The transmission has developed a transmission whining noise which Toyota has released a TSB 0008-21. My vehicle has 104,000 miles and is now out of warranty. If this is a known defect on many Toyota vehicle models a transmission replacement should be free if no longer in warranty.

To whom it may concern I hope I've chosen the proper avenue for my problem. I purchased and new 2021 Toyota Highlander. I chose Toyota for it reputation of high standards of dependability. However I took the vehicle in at 20,611 miles (9/22/2021) into the dealership for multiple transmission issues. When passing it would kick down into a lower gear and race the motor. There was also chunky shifting and a small whining noise. (service Ref #XXX). The service manager only wrote down the first symptom. Upon doing a computer diagnostic without driving the vehicle the service manager told me to just drive it more that it probably needed more breaking in. The downshifting and chunky shifting did go away for the most part, but the whining persistently got worse. Finally at 115,000 miles it got much worse and I took it back to the dealership. They informed me that the transmission needed replaced at over $9,000. I reached out to Toyota upon finding out there was a in company TSB alert for this very symptom (Case #XXX). Toyota informed me there was nothing they were willing to do since it was out of warranty even though I reported the problem with no resolution when it was in warranty. My wife and I are in our [XXX] and don't have cash like that. we don't feel we should be responsible for the repair, especially when the issue was report properly before the warranty expired. How can you help? Thank you for your attention. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I brought my 2021 Highlander L in for some regular maintenance and reported that within the last 2 weeks I have been hearing a whining sound when the vehicle is decelerating. I was informed at the end of the day that the transmission is bad and needs to be replaced. My vehicle is just outside of warranty (69k miles). I have always ensured my Highlander got an oil change on time, had all recommended maintenance done at that appropriate time/milage, and brought it in for safety recalls promptly. This vehicle has never been in an accident, and while I have owned it (and according to Carfax when I purchased it) I have always brought it to a Toyota dealership for any and all work. There have never been any warning messages, and even though my vehicle has been into Toyota regularly for oil changes and regular maintenance, I was never notified of any other issues. I also use this vehicle at least once a year for road trips (over 200 miles) and before every trip bring it in to have it checked. I'm being told it'll be about $10K to fix. Based on my research I have discovered this is a problem MANY people with a 2021 Highlander are having, also a class action lawsuit was filed due to transmission issues but only covered Highlanders up to 2020. This seems to be the same issues those vehicles had but I'm being told it's not covered or a recall.

SERVICE BRAKES
37 complaints
I own a 2021 Toyota Highlander Hybrid. The vehicle exhibits a dangerous braking surge defect. When braking during cornering or in stop-and-go traffic, the vehicle randomly surges forward even though the brake pedal is depressed. This creates a serious safety hazard and increases the risk of collision. On multiple occasions, this defect has nearly caused an accident. The last time it happened we were driving in stop and go traffic and the vehicle surged forward while depressing the brakes and the engine died leaving a red triangle on the dash. Toyota has acknowledged this condition through Technical Service Bulletin T-SB-0059-23, which applies to my vehicle. The bulletin involves reprogramming the brake actuator assembly control module to address the braking transition between regenerative and hydraulic braking. Despite this, Toyota has refused to apply hybrid system warranty coverage, misclassifying the defect as a conventional brake issue. My vehicle is available for an inspection. I contacted Toyota corporate, who initially responded but failed to provide follow-up or resolution. The defect persists after the bulletin was applied. Toyota’s refusal to cover the repair under the hybrid warranty leaves me with an unresolved safety defect. This complaint is intended to document the ongoing safety risk and Toyota’s failure to provide adequate remedy under warranty. I request NHTSA investigate this issue as a systemic safety defect affecting 2020–2022 Highlander Hybrid models.

When I apply my foot to the brake pedal the car slows, but just as I am about to reach the final part it feels like the brake is let go and the vehicle goes forward and I have to push harder on the brake to stop the vehicle. This issue can cause me to run into a vehicle that is stopped. I have not taken it to a dealer yet. No warning signs on the dash. This has been going on for about a year now.

My 2021 Toyota Highlander Hybrid has a braking issue identified in Toyota Service Bulletin T-SB-0059-23, Hybrid Regenerative Brake Transition Feeling Improvement. When going downhill and applying the brake, the vehicle lurches forward temporarily as the braking system transitions from regenerative to hydraulic braking. The first time my vehicle did this, it was very alarming and I had to take additional measures to slow my vehicle as I was driving downhill. My vehicle frequently demonstrates this problem, however, I did not report it to my local Toyota dealer because I read in an online chat group that it was a characteristic of this vehicle. Although the TSB recommends a Reprogram of the Brake Actuator Assembly Control Module, the repair is only covered under the Toyota Basic Warranty which is in effect for 36 months or 36k miles, whichever occurs first. My vehicle is past the warranty limit, and because I did not report it to my dealer previously, this repair is not covered under the TSB or the Toyota Basic Warranty. Toyota Highlander Hybrid model years 2020-2022 are affected. The Technical Service Bulletin was issued August 29, 2023, so if a 2020 model Highlander Hybrid has this problem, 2020 models would have already passed the warranty limit by the time the TSB was issued and thus would not be covered. This is a safety risk as drivers can lose control of the vehicle when braking, particularly when going downhill. The Warranty should be extended, or this problem should be elevated to a RECALL so that older affected vehicles, or those with higher mileage can be covered under warranty. Drivers should not have to pay for a recognized problem that affects the safety of this vehicle and has been identified in a Technical Service Bulletin. This problem puts drivers at risk of losing control of the vehicle and the problem can be mediated with a software reprogram. T-SB-0059.23 should be elevated to a RECALL, or extended regardless of age or mileage.

As your braking coming to a stop, the vehicle surges forward, feels like you lost your brakes and then it stops. If the car in front of you were to stop suddenly, you would hit them from behind. It had been going on for a while, but since it was my wife’s car she said she just stayed way back from the car ahead of her. I came within inches of hitting someone in early June 2025. I took the car to my Toyota dealer June 25, 2025 and they said there was a computer update for the braking system. It took away most of the problem, but it still surged.On August 19, 2025 I took the car back to the dealer where they had another computer update for the brakes. We will see if that works!! I feel it’s a safety issue, we should have been notified. Out of warranty cost me $348.01

Started with a transmission whining. Now is setting check engine light and jerking. Toyota knows there is a manufacturing defect in the UA80 transmission in these vehicles, but continued to sell them even after the released TSB# T-SB-0008-21, and refuses to repair this under warranty. Toyota is the only company offering replacement transmissions and therefore can set there own price to scam consumers. Please help us get a resolution.

Glass in sunroof exploded, loudly, while driving on interstate, at 65 miles an hour, showering passenger and driver in shards of glass. There was no impact to the sunroof. Just a loud explosion. Heavy traffic at high speed while covered in glass had to make emergency stop. Glass could have easily gotten in our eyes. Thank goodness the two of us were wearing a ball cap and a visor. Would gladly have car available for inspection upon request. We will take pictures.

Transmission. I believe the transmission is defective. A lot of customers has complained that toyota Highlander 2021 transmission is defective I was driving my car and the transmission went bad, I could not move my car again. I had to tow it to a mechanic and they diagnose that the transmission is bad

My car has been making a grinding and whining noise. I took it to the dealership and the service manager stated Toyota has been having a known issue on transmission and it will have to be replaced. The vehicle can stop working while i am driving and cause a very bad accident.

The sunroof glass on our 2021 Highlander unexplainably shattered on our ride home on 7/20/25 at approximately 12:30PM. Sky was overcast, and the temperature was in the mid 80's. We had just entered the highway and were still accelerating to highway speed. We were not near a pedestrian overpass where a rock could have been tossed from above. Broken glass edges are pointing upward. The sunroof was in the fully closed position and not tilted. Safety would have been at extreme risk if we did not have the inner slide closed. The vehicle has not yet been inspected by the Toyota dealership or insurance.

Recall remedy is not a available in timely manner. Recall # 23ta15
Dec 01, 2025
The contact owns a 2021 Toyota Highlander. The contact received notification of NHTSA Campaign Number: 23V865000 (AIR BAGS). However, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure.
Oct 21, 2025
The contact owned a 2021 Toyota Highlander. The contact stated that while his wife was driving at an undisclosed low speed and in the process of merging into the highway, the vehicle was suddenly rear-ended in the rear quarter panel area, near the rear tire, causing the vehicle to face oncoming traffic. The driver-side and passenger-side air bags did not deploy. The message "Park Brake Malfunction" was displayed. The contact transported his wife to an urgent care clinic the evening of the incident for a medical check-up because the contact's wife was pregnant and was starting to feel pain. The contact's wife sustained neck injuries. A police report was filed. The vehicle was towed to a tow yard. The insurance company was notified of the incident and towed the vehicle to Copart to be inspected. The vehicle was totaled. The manufacturer was not made aware of the failure. The failure mileage was approximately 51,000.

The airbags did not deploy when I was involved in an accident on the freeway July 2025. During the collision, there was a message on the driver dashboard that read "SRS Airbag System Malfunction Visit Your Dealer". When I took my Highlander into the collision autobody shop, they notified me that my car had an open recall and that I needed to get in touch with manufacturer or schedule an appointment with a local Toyota dealership to see if they could remedy the recall as soon as possible. When I called Toyota, they confirmed that there was a recall on the Highlander's that opened in 2023 and that there was supposed to be a remedy in 2024, but unfortunately there is still no remedy available. They let me know that I would not be able to bring the vehicle in for service and that the collision center would not be able to remedy the situation on Toyota's behalf. This safety issue put myself and my family that includes multiple children that were in the vehicle at the time of the accident, in a very unsettling situation. We were afraid to drive the car any further than 5 miles or on the freeway, wondering if the airbags would deploy at any minute. There was little to no information provided whether the airbags were in fact supposed to deploy upon impact compared to if it was just a sensor mishap. There were no prior warnings, message, symptoms or mailers sent out notifying us that there were any recalls on the car.

The component that has failed is the passenger airbag system under Toyota Recall 23TA15 (Interim Notice 23TB15). The recall notice states that the passenger airbag may not deploy in the event of a crash. My vehicle is a 2021 Toyota Highlander (VIN: [XXX] ). This safety defect has been outstanding and unresolved for over 21 months with no available repair or remedy. The vehicle is available for inspection upon request. The safety of my family is directly at risk. I am a mother of three young children, and we frequently travel with passengers in the front seat. If the passenger airbag does not deploy during an accident, it could result in catastrophic injury or death to anyone sitting in that seat. This ongoing recall forces me to make a difficult choice between risking my family’s safety or not using the vehicle as intended. The problem has been acknowledged by Toyota and confirmed by their recall notice. I contacted Toyota and opened a case with their Brand Engagement Center, but they denied my request for assistance and informed me there is no current remedy. I was told my case has been taken to the highest level within Toyota and that the only option left is to pursue lemon law. The vehicle has been inspected and serviced at Toyota authorized facilities in the past, and Toyota has my warranty and repair history. However, since the recall remedy does not yet exist, no inspection has resolved the issue. There have been no warning lamps, dashboard messages, or other visible symptoms prior to or during this recall; the only notice is Toyota’s acknowledgment that the defect exists and has not been fixed. In summary, I have been forced to drive an unsafe vehicle with a known airbag defect for nearly two years. This delay in remedy is unacceptable and puts my family and the public at risk every day. I am requesting NHTSA’s assistance in holding Toyota accountable for this unresolved safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Failed seals on roof rack that allowed water to enter the A pillars. Unknown potential damage to air bag system, and electrical wiring. Smaller leaks can go undetected and damage components over time without owners knowledge. Dealer confirmed water intrusion, Toyota refused to repair the defect. Toyota is aware of the problem and had issued a service bulletin on April 22, 2024 (T-SB-0040-24) with a range of 2020-2023 Highlander vehicles affected. This defect may also affect components within the B pillars, and more.

The contact owns a 2021 Toyota Highlander. The contact received notification of NHTSA Campaign Number: 23V720000 (Structure). The contact stated while driving approximately 35 MPH and exiting a highway with his family, the front bumper assembly detached from the vehicle. The contact stated that the vehicle was steered to the side of the road where duct tape and glue was used to secure the bumper, and the vehicle as taken to the residence. The vehicle was then taken to the dealer where the dealer and the dealer refused to perform the recall repair due to temporary repair that the contact had performed. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

I purchased a 2021 Toyota Highlander Hybrid brand new. This vehicle was manufactured during COVID (production date of 10/2020) with significant mfg defects that have surfaced after several years of ownership. Both the passenger and driver’s side doors have growing cracks/defects which has slowly caused the doors/windows to bow out. A collision company estimates the repairs to be at least $11,000 and after confirming that I had no accidents or work done on the vehicle to cause this problem, agreed that this is a manufacturing defect. Toyota has additionally refused to acknowledge that the vehicle is most likely a safety hazard to drive with the window now so bowed out on the passenger window, that it is exposed to the elements. The Corporation has refused to remedy the mfg defects citing that it has been 4 years and too many miles later, even though I have a nearly 4 year history with them of meticulously taking my vehicle in to get serviced etc. Ultimately they know that this defect was a hidden/growing problem, but because of the extent of the damage involved, they have refused to take ownership.

FUEL/PROPULSION SYSTEM

My gas tank does not fill up to 17 gallons like it claimed it would when I purchased the vehicle, It also keeps automatically shutting off after filling up a little bit 8-10 gallons and it is not full, I have to hold the handle and fuel manually and constantly worried its going to over fill.
Nov 22, 2025
Impossible to completely fill the gas tank on the Highlander Hybrid. 17+ gallon tank, yet car will accept at most 12-13 gallons of fuel. Fuel gauge reads between 3/4 and 7/8 full after each fill-up. This issue has persisted since the vehicle was new. Multiple requests to the dealer to fix this problem are largely ignored with them telling me that they aren't aware of any issues, research suggests that many other owners are experiencing the same problem.
Feb 28, 2022
SINCE I HAVE OWNED THE 2021 HIGHLANDER, THE LOW FUEL WARNING LIGHT DOES NOT COME ON UNTIL NEARLY EMPTY. THIS HAS BEEN AN ISSUE SINCE DAY ONE. MY LAST TOYOTA THE LOW FUEL LIGHT TYPICALLY ILLUMINATED ON THE DASH AROUND 35 MILES DTE. I WAS RELIEVED TO SEE TOYOTA ISSUED A SPECIAL SERVICE CAMPAIGN (21TC05) ACKNOWLEDGING THE ISSUE... BUT IT DID NOTHING TO FIX THE PROBLEM!! I HAD THE REPROGAM SERVICE PERFORMED AND STILL, THE LIGHT AND DTE DID NOT IMPROVE OR CHANGE. THE LOW FUEL LIGHT DOES NOT COME ON UNTIL ABOUT 10 MILES DTE. AND I ONLY GET 16 MPG, SO THIS IS VERY LITTLE WARNING ESPECIALLY IF TRAVELING OR GAS STATIONS ARE NOT AVAILABLE IN A REASONABLE DISTANCE. BACK TO THE DRAWING BOARD TOYOTA!
Feb 25, 2022
My concern has to do with an inability to completely fill the gas tank in my 2021Toyota Highlander Hybrid XLE (AWD), and the gas tank capacity has worsened over time. I purchased the vehicle new from a Toyota dealer in Maryland in April 2021. Initially, I could fill the gas tank to almost full per the gas gauge. Over time, the amount of gas the tank can hold has decreased. As of early 2022, I can only fill the tank to just above 3/4 full per the gas gauge. Please note that when filling the tank at a gas station, I always stop filling when the gas pump shutoff switch activates (1st click) - I never "top off" the tank. It is certainly annoying to not get anywhere close to advertised range of the vehicle (the vehicle display shows a range just over 400 miles/tank versus an expected 600+ miles). However, my main concern is safety-related - I don’t trust my fuel gauge and fuel monitoring system, and as a result I fill the tank whenever I approach 1/2 full per the gas gauge. This is so I don't inadvertently run out of fuel. In Sept 2021, I took my vehicle to the Toyota dealer where I purchased it to report this fuel tank issue. The dealer's service department "verified [customer's] concern that the fuel pup clicks off before gas tank was full." The dealer also "created a TAS Case #xxx and with the information give was informed there is an active investigation by Toyota on this concern and there is no repair available at this time." Since then, the dealer has not reported anything new from Toyota USA (they said "we'll hear about any fix the day before you do.."). I called Toyota USA last Fall and also got no indication on an impeding fix. Bottom line - Toyota USA has been silent on the matter, although there is certainly lots of online chatter from other owners and mention of a lawsuit against Toyota. I am wondering if this issue is similar to what was noted (and finally fixed?) for Toyota's late model RAV4 hybrid vehicles.
Feb 02, 2022
CAN NOT FILL IN A FULL TANK OF GAS. AT MOST THE CAR TAKES 13 GALLONS, WHERE AS THE TANK CAPACITY IS 17, WHICH IS 4 GALLONS SHORTER AND GIVES 140 MILES SHORTER RANGE (CALC ACCORDING TO EPA RATING). 140 MILES IS A HUGE DIFFERENCE. EVEN IF YOU FILL MORE THAN 13 GALLONS, THE RANGE STAYS AT 423 MILES AND DOESN`T INCREASE.

My 2021 with 73000 miles is now at a dealershop 700 miles away from home. I didn't drive far while away but a week into my vacation, i started hearing a whining sound upon accelerating. Sound seemed to get louder on second day of hearing the sound. Took it to a dealership in the Leesburg Virginia area....they charged me 203.00 for diagnostics and indicated need new transmission for near $11,000. Each time I went to my dealership in my area for an oil change, they indicated that I needed a transmission fluid change. I read that when Toyota installed a "Sealed Transmission System" these changes would not be needed or at least limited.... Because the so call system is sealed, only dealership techs can check your fluid levels. How do you know if, when they check it, do they replace what they took out and if they do this regularly and don't refill what they took out, your fluid would eventually be pretty low...there is no way to check because "Sealed Transmission System" is only check by the dealerships (no transmission fluid dip stick on 2021 highlanders (and 2022, 2024, 2025). So you can't check it like an oil dip stick. We're [XXX].....INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 21 Highlander has a wine noise coming from the transmission. There is currently a bulletin out by Toyota T-SB-000821 confirming that the transmission in this model needs to be replaced. I took my car to two separate mechanics who confirmed the noise is coming from transmission. I called Toyota this morning. Spoke with a lady and she told me she cannot locate the bulletin on my VIN number so pretty much there’s nothing they can do to help. I’m having the issue with my car that Toyota is aware about and has put out a bulletin regarding the issue. I think Toyota needs to take care of this. This is not something that should be VIN specific if I’m having the issue then fix it! At least send me to a Toyota dealership for you guys to confirm the issue and fix it!

TRANSMISSION, Jolts when backing up, and hesitates in traffic. The dealership confirmed it's the transmission. No warning lights, just running poorly with hesitation, afraid of breakdown. First appear a month ago after my warranty expired. I have a 2021 Highlander with 80,000 miles and still owe $22,992.84 on the vehicle. My warranty 60/60,000 is of is not any good. The issues is the transmission. The dealership is telling me it's not covered even though this is an issue with this model. For a another $11,000 they can install a new transmission. Toyota you are better then this, my Camry I had almost 300,000 on it. I had another highlander before this one. Very disappointed.

My car out of no where once it hit 60k miles (which makes it fall off warranty) I start having transmission problems. It’s a 2021 which is very weird for that to happen. Bought it brand new. I was driving with my kids in the car on the highway and the car decelerates and I freaked out. I see that I’m not the only one that is having this issue and it looks like it’s 2020-2021 models that are having transmission issues and I think this needs to be something to get checked. Automatically after driving the car decelerates and you don’t know where or when it can be the rpm drops. Took it to the dealership they said it’s transmission but a brand new car right when it hits 60k miles then this happens.

Vehicle windshield glass has a distorted and wavy quality that impacts visibility for the driver. I have contacted the dealership about this issue and there is not a current recall for the windshield. The windshield says Toyota Pilkington laminated acoustic heated [XXX] , DOT15. I purchased this vehicle in the last week and did not notice the distortion on the short test drive. At first, I thought it was a reflection issue from the dash, but it is not.

The driver side mirror wiggles at highway speed or with strong wind and the image in the mirror is not clear which causes the driver to do a double take on where and how far the car is. This is a safety issue that needs to be addressed and fixed by Toyota. I’m not the only one experiencing this issue, see other reports. Thanks for your quick action on this matter.

Visibility for interior windows defroster/defogger is not functioning. Inside windows are fogging up and icing no matter what heating setting is used. This poses significant risk of visibility in all windows. I have had to try to defrost the inside of my windows just to see out of my side windows and see in my rearview mirror. I have not gone to the dealership, but do intent to. No warning messages present.

Driver side mirror vibrates and gets worse on the interstate and windy days. It does not give clear, steady view. Night time all you see is shaking headlights. It’s highly distracting and discomforting to eyes and causes headaches. Taken it to dealership plenty of times. It was replaced one time and still same issue. Dealership contacted Toyota about the issue and still no solution.

Premature AC refrigerant leak and failure in system in the 2021 Toyota Highlander due to corroded/defective rear AC lines located near the exhaust/spare tire, observed at very low mileage and upon official inspection at the nearest Toyota dealership. Noticed early in ownership and decided to have the vehicle scanned when air being released only continued to grow warmer in the sweltering summer months. Reporting due to advice from friends and owners in my exact situation with the very same issue as well as the pricey three-thousand dollars and upwards quote to have this work done from Curry Toyota, 3026 E Main St, Cortlandt, NY 10567. Vehicle purchased new to avoid these very issues.

The contact owns a 2021 Toyota Highlander. The contact stated while driving at 55 MPH, the driver’s side mirror was vibrating abnormally. There were no warning lights illuminated. The vehicle was taken to a dealer and the vehicle was diagnosed and it was determined that the screw securing the mirror had loosened. The vehicle was repaired; however, the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was approximately 38,000.

I feel this makes it very hard to see properly especially on the interstate traveling 70mph & trying to get a clear view of the roadway & cars around me. I took the car to my local Toyota dealer & was told this is a common problem among the new design with the Highlander’s. I do not feel safe not being able to see properly.

The contact owned a 2021 Toyota Highlander. The contact stated while driving approximately 50 MPH with a passenger in the rear passenger seat, she heard an abnormal popping sound and the sunroof exploded from the inside-out without warning or impact. The shattered pieces of glass were propelled outside the vehicle. The occupant in the rear passenger seat sustained a cut on the finger but did not seek medical assistance. The vehicle was taken to the local dealer where it was diagnosed that the sunroof glass panel needed to be replaced and it was confirmed that the failure was not due to an impact to the sunroof. The vehicle was repaired. The manufacturer was not notified of the failure. The contact stated that she was concerned about a potential reoccurrence of the failure. As a result, she traded the vehicle. The failure mileage was approximately 7,500.

The headlights of the Toyota Highlander are too bright for other drivers. When driving at night, I am constantly flashed because the drivers think the highbeams are turned on when in fact, the lights are too bright for their visibility.

The front headlights (low beam) are aimed too high resulting in blinding of oncoming drivers. More than half of all oncoming cars flash their lights suggesting. This has occurred for a year and a half since the vehicle was purchased. While a small adjustment was made to the headlights by the vehicle owner, this type of adjust was denied from the Toyota service department, and should never have been needed in the first place.

The rear hatch of the vehicle started malfunctioning right when the three year manufacture's warranty was expiring on 08/2024 (very convenient). It would only open part way, barely or sometimes not open at all. One instance, my dog's tail got stuck in the hatch and it would not open. I had to force it open and thankfully I am able to do that. January of 2025 I took the car into Will's Toyota in Twin Falls, ID (where I purchased it new) and they told me that my option was to replace the hydraulic struts that were $1000 for the service. I took the car in on 10/23/25 due to the issue getting worse to have them replace the hydraulic struts. The dealership said they've had a lot of cars with the same issue. I just do not understand how a company can sell a car and a major part of the car fail conveniently when the warranty is to expire. Oh and I called Toyota customer service to complain and they said they don't keep track of this kind of thing...

[XXX], while driving on a [XXX], my 2021 Highlander Platinum unexpectedly shut down without ANY prior warning or indication of a malfunction. This abrupt failure put my safety, as well as that of my passengers and other motorists, at considerable risk. As a longtime Toyota customer, I have always valued the reputation of Toyota vehicles for their reliability and safety. However, this incident has significantly shaken my confidence in that reputation. I trusted that my vehicle, particularly one as recent as the 2021 Highlander, would perform safely and effectively in all driving conditions. The complete and sudden failure of the vehicle on a busy highway is not only unacceptable, but also alarming. I now find myself questioning whether I can continue to rely on this vehicle or the brand itself. After having the vehicle towed from obstructing a busy lane of traffic, the battery was jump started to get the car running again. I had NEVER had ANY issues with battery and all regular services had been completed at a Toyota Service Center, but several codes appeared on the dashboard after this incident advising the vehicle be taken to a dealer. Vehicle was taken to Toyota Service Center [XXX] for a diagnostic check, but they couldn’t find any error codes or issues with the vehicle. I contacted Toyota to thoroughly investigate this matter and address the underlying issue that caused the shutdown, so that I can regain confidence in its safety and dependability.

The contact owns a 2021 Toyota Highlander. The contact stated while driving 60 MPH, the vehicle inadvertently attempted to navigate the steering and lane direction to the opposite direction of where the contact was attempting to steer the vehicle. This caused the contact to manually steer the vehicle into the center lane. There were no warning lights illuminated. The contact took the vehicle to a local dealer who inspected the vehicle but could not diagnose the cause of failure. The dealer informed the contact that the vehicle lane sensor and steering assist sensor were performing as intended. The contact was concerned that the sensor should be adjusted so that the sensor would not have to adjust so easily while the contact was driving. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 5,000.

I consider this a vehicle safety issue. Was on the freeway, center lane of a 3 lane highway. The vehicle to my left began to move into my lane. I had to quickly move to my right, activating my lane departure and steering assist. This caused my vehicle to attempt to move me back into my lane (where the other driver was now trying to occupy!). I was shown how to disable this feature if desired but what I wasn't told by the dealer, is that this feature can no longer be set to default to off. I just finished a lease of a 2018 Toyota Rav4 which also had this feature but once I disabled it, it was disabled unless I re-enabled it. With this new vehicle, when you disable this feature, it's only disabled until you turn off the vehicle. When the vehicle is turned on again, this feature is set back to active. I checked with the dealers service department and they said that this is how this feature will work moving forward, that you can no longer set it to off as the default setting.

Almost caused high speed accident merging onto toll road! The vehicle is experiencing a severe transmission slippage, shudder, and grinding noise, consistent with TSB-0008-21 (UA80 transmission failure). This defect causes hesitant acceleration and erratic shifting, creating a safety hazard when merging onto highways or crossing intersections. I am concerned the transmission will fail completely while driving, resulting in a sudden loss of motive power and increasing the risk of a crash. Toyota has covered this exact safety defect in 2017–2019 models (CSP ZJC) but has failed to recall the 2021 models despite identical symptoms. First reared it's head as slipping when putting vehicle in reverse, 25k ago. Was told by Toyota Certified mechanics it was an operator error. Morphed into larger issue.

The vehicle pulls/jolts foward as I slow down at a stoplight. At first, I thought this was normal, but over the past year, I've noticed something unusual, possibly with the gear shifting. It has become more noticeable over time. It has happened enough where I almost get into a fender bender with the car in front of me. I started researching this issue and it's a common complaint among other Highlander vehicle owners. [XXX] . I reported this issue to the Toyota Dealership and all have stated this was normal. I have also seen other issues with the transmission with the similar year and build. Leading me to believe this car may have an early sign of transmission issues.

About 15 minutes prior to the incident, the interior shade cover was closed beneath the moonroof. Mostly sunny day about 85° F, about 55mph, the moonroof exploded. The sound was that of a shotgun, followed by wind noise and tinkling noises of shattered glass just beyond the shade cover. Upon external examination, 100% of the glass sliding moonroof was shattered, approximately 30% of the glass had departed the vehicle from a forward and central portion of the glass area. The remaining glass was bowed outward. The roof aft of the moonroof displayed 1-3 millimeter length flags of clear coat paint where the glass shards had etched the painted surface and the rear spoiler fairing panel over the aft hatch had gouges in the plastic composition along the upper surface of said fairing. All components on the vehicle were factory installed. Vehicle had 10,000 miles and was in service just over 5 months. There were no indications of an impeding problem. The moonroof was secured with tape and cardboard to prevent shards of glass from departing the vehicle. The dealership body shop estimates repairs at $4319. Safety threat: If shade were open at the time of explosive incident, shards of glass would fall onto driver and passengers, which might create a loss of control from panic (explosion was very loud and disconcerting) glass in facial area (between eyes and sunglasses) or falling into clothing at the neck area and creating a painful bloody situation at highway speeds. Shards of glass departing incident vehicle might reach a following vehicle (motorcyclist) depending upon upward trajectory of glass and forward speed. Might affect vehicles traveling in opposite direction. Driver following incident with window down might be exposed to shards of glass slip streaming into that vehicle.

Vehicle: 2021 Toyota Highlander XSE Approximate Mileage: 92,000 Location: Boerne, TX (Texas Hill Country) ⸻ Summary of the Problem: My vehicle experienced serious electrical failure after heavy rainfall in the Texas Hill Country, where catastrophic flooding recently occurred. At a red light, the dashboard began flashing, power windows stopped working, and the electronic parking brake would not disengage. I was nearly rear-ended with my children in the car because the vehicle temporarily lost responsiveness. ⸻ Pattern of Issue: This problem only occurs after rain. Once the vehicle dries out, the systems return to normal. Toyota tested the battery and alternator and found no faults. The dealership and Toyota Corporate have been notified, but they have so far refused to approve a Goodwill Repair or perform deeper inspection for water intrusion into the fuse box, firewall harness, or Body Control Module (BCM). ⸻ Suspected Cause: I believe there is water intrusion due to a design flaw, likely through the windshield cowl or firewall. Other Highlander XSE owners have reported nearly identical symptoms following rain exposure. Toyota has issued service bulletins in the past about water reaching electrical components in other models. ⸻ Safety Concern: This is a serious safety issue. A near-crash involving my children occurred. If Toyota does not resolve this issue and it leads to an accident, I will hold them fully accountable. I am reporting this so it can be formally investigated and linked with similar complaints.

Vehicle was driving at highway speed, transitioning to off ramp. Warning lights came on stating Braking Power low. Brakes proceeded to fail. Stepping on brakes did nothing but initiate a stuttering response. Vehicle would not slow down. Rolled into dealership that was luckily .5 miles away. It was diagnosed to be a wheel speed sensor. A sensor failing should not cause a vehicle to be unable to brake. Shocked and traumatized over the incident.

This is in regards to a 2021 Toyota Platinum AWD with 8500 miles. While cruising at about 40 miles/hour, the car suddenly lost power, and an alpha numeric code popped on the digital display that said “Chip malfunction” and something else I don’t recall. It also said to see your dealer immediately. On the dash, the check engine light came on with a message that said “reduced engine power”. This message alternated with another alpha numeric code. I did not write down the actual codes because I thought the car would record them. I was able to roll onto a side street and turn off the car. After 5 min, I restarted the car and took it to the dealer later that day. They not only could not find a code in the record, the entire trip was not recorded, even though it’s on my Toyota app. First, they tried to say it couldn’t have happened because it was not recorded. Then, they said the recall regarding a power issue was the culprit, but also admitted the “fix” had nothing to do with, and would not affect, the engine. After insisting more be done to iD the problem and fix it, they agreed to keep the car and run a diagnostic. It turned up nothing except “maybe bad gas”. Really? We only use premium from reputable sources. I do not feel safe on the car and most certainly do not feel safe putting my child in it. I cannot believe they cannot find the problem.

Yesterday, as I do a couple times a month, I went to switch parking places, putting my 2021 Toyota Highlander where my 2007 Mazda was parked, in order to drive it and keep the battery from dying. After starting both cars I first moved the Mazda to make room for the Toyota. As I was slowly steering the Toyota at (idle speed) into the now vacant parking spot, the car accelerated on it's own, prompting me to hit the brakes, but to no avail. The car jumped the curb hitting, knocking over and and damaging a large ceramic planter and small tree in my neighbor's yard. My split second reaction upon having no brakes and a run away car was to push it out of drive, which ended up putting the car into reverse, causing a harsh jolt, followed by the car accelerating again on it's own, in reverse towards another neighbor's garage. I live in a condo complex, so all of this took place within about 30 feet of forward/backward/forward motion. My second split second decision (with no brakes) to avoid smashing into the garage was throwing it back into drive, which sent it accelerating back towards the parking place again. This time I had the presence of mind to push the power button on the dash, allowing me to barely come to stop before jumping the curb again. Whole thing lasted about 15 seconds. I had an appointment to attend, so after a brief conversation explaining to my (now outside) neighbor what happened, I left in the older car. Returning later in the day I found damage to the front of my Toyota and wonder if my transmission is damaged as well. I'm reimbursing my neighbor today. I've not attempted to drive the Toyota since, and am seeking your advice on how best to proceed, whether I should initiate contact with Toyota regarding this incident, or is that something you should initiate? Please advise. Thank you.

Upon attempting to engage the brakes, it was found that they did not work. Immediately thereafter, the car began an uncommanded full acceleration. The insurance company has totaled the car. Our safety as occupants was obviously at serious risk. The driver chose to take the car off the road rather than jeopardize the lives of others on the same road. The car plowed through boulders and trees, coming to rest upside down wedged between an earthen berm and a tree......suspended about 2 feet above the ground. There were no warnings prior to the incident. The car has been inspected by the insurance company, and has been authorized for inspection by the manufacturer. There were no serious injuries as a result of the accident. We were VERY lucky! Uncommanded acceleration without any control is a frightening event any time....but definitely in the vicinity of other vehicles full of families.

My vehicle was rear-ended while stopped by a 2014 Toyota Corolla that was estimated to be traveling between 60-70 miles per hour. During the crash, the driver seat failed, resulting in the partially reclining into the second row passenger. The failure mechanism appears to be internal to the seatback, as the seat twisted during the failure, causing me to lean more towards the passenger side of the vehicle.

I was vacuuming the second row carpet in my vehicle. I was leaning into my vehicle and pulled the second row seat release to move the seat back. The back of the seat flipped forward hitting me in the right side of my head so hard it resulted in a pinched nerve at C5-C6. It was a substantial blow. I had to stop what I was doing and sit down. I would be very concerned at that amount of force hitting a child. Has Toyota measured the force and done a risk analysis to the vehicle occupant?

The electric park brake makes a loud screaming sound during engaging cycle as I put the gear in park. The sound gets worse during warmer weather. I visited the dealer twice for the same problem and reported it to Toyota. During my visit another highlander came into dealership. It made the same sound when the driver placed it in Park. According to the dealer, this sound is normal. I say it’s not. I have way cheaper cars with Electric park and they don’t make this sound. If the park brake unit fails it’s going to be real costly to repair and may fail while driving and gets engaged.

While accelerating onto the freeway the vehicle suddenly loses power creating a serious safety issue. A check-engine light comes on but the safefy issue is that the vehicle goes into a power loss mode ON THE FREEWAY. A truck nearly rear-ended me the first time it happened. Toyota Service was unable to duplicate and so said National Toyota advised them to release the vehicle back to me. The same issue happened to my boyfriend and his son - total loss of power while accelerating onto the freeway. Then a mechanic recreated the issue 5 additional times (usually in the dawn hours when traffic was light due to safety concerns). Was unable to find the cause of the issue but a loss of power in a vehicle is as serious a concern as an unwanted acceleration. I am frustrated that Toyota is not taking this seriously.

Unwanted acceleration happen more the 5 to 6 times. While driving in highway exit ramp my vehicle lurched forward while I was trying to slowdown. Dealership had the vehicle for more than 2 days and unable to duplicate the issue. Currently Toyota dealership informed they don't any know issues or condition like this.

I was heading up a hill into a slow stop at a stop sign and once I applied the brakes it suddenly jolted forward for a second until I slammed on the brakes more over riding it. I have had the car for a week and thought it could be just happen stance but it has happened multiple times.

Upon starting my 2021 Highlander Platinum with 10,700 miles on it several warning lights repeatedly came across my display including reduced engine power, brake system malfunction, pre collision system malfunction. See your dealer. No codes showed up on their scan but every time they cleared the screen the messages came back. They decided it was a bad knock sensor. Then I received a call that a critter had chewed wires and they might find further damage. I was surprised because I’ve been in my house for 45 years and I’ve never had a critter in my garage. The service manager said “Toyotas attract critters because of the covering they use on the wires.” I said, “Soy?” And he said, “Yes”. So, isn’t this a manufacturing defect? How many times a year is this going to happen? I’ve owned Toyotas for 27 years. I’ve never had a problem until this car. I’m also having problems with the navigation system, 2 visits to the dealership and 45 minutes on the phone with the Toyota Engagement Center.

Rear passenger seatbelt has torn in multiple places. I believe something inside may be cutting it when it retracts. The buckle is now stuck in a tear and the seatbelt will not fully retract. Toyota refuses to fix it under warranty because it’s “not usual wear and tear” and there’s no recall. I believe this is a significant safety risk.

We had to cut a seatbelt because it was cutting into a child’s stomach. The child was screaming and complaining and it left a scar on his stomach.

Forward Collision Warning and Automatic Emergency Braking isn't functioning as stated in the Toyota Highlander 2021 Owner's Manual. Dealer stated that software tests were conducted and the vehicle's radar and optical sensors are performing in accordance with the test results. However, there is only intermittent warning lights and alarms that are functioning. The dashboard audio and visual alarms only function in rare encounters on approaching a vehicle. The service manager rode with me and when I was approaching a vehicle where an alarm should have sounded or illuminated inside the vehicle, that did not occur. However, the software tests showed that the vehicle was approaching on a collision event that was recorded on the system, but failed to alert the driver. After additional testing, the service manager stated that the vehicle reads stop lights from the vehicle ahead to execute the safety functions of the forward collision warning and automatic emergency braking safety feature. The Owner's Manual doesn't make that claim. In addition, another service manager stated that the system uses artificial intelligence to learn the driver' habits and the system adapts to the driver. The Owner's manual doesn't state that claim either. Lastly, the invoice stated that the owner should read pages 257 and 260 of the Owner's Manual to understand how the system operates. This describes the Dynamic Radar Cruise Control functions and not the Forward Collision Warning or Automatic Braking functions. This information is found on pages 235-238. They missed the problem. My suggestion was that their test only looked at a single variable that may have covered the external sensor operation and didn't test the dashboard internal warning system of the audio/visual alerts inside the vehicle. My recommendation was to seek assistance from the supplier that manufactured this system and seek guidance from their engineering staff. I complained to the Toyota Corporate Customer Servi

I am reporting a serious safety defect involving the rear brake system of my 2021 Toyota Highlander, purchased from Penn Toyota (Glen Cove, NY). The dealership represented the vehicle as “Toyota Certified” and indicated that it passed all safety inspections. On November 15, 2025, I discovered that the rear brake rotors and pads were in extremely unsafe condition, showing severe corrosion, deep pitting, uneven pad wear, and structural deterioration. This damage clearly developed over a long period of time and indicates that the vehicle could not have passed a legitimate safety inspection at the time of sale. The rear brakes had to be replaced immediately to prevent potential brake failure. After replacing the rear rotors and pads, the vehicle passed the New York State Inspection on the same day, proving that the previous brake condition was unsafe and improperly inspected. This raises concerns of: Brake safety failure Improper or falsified dealership inspection Risk of reduced stopping power Potential loss of vehicle control I am submitting photos, the repair invoice, and the inspection result that confirmed the brakes were unsafe prior to repair.

This is a supplemental complaint to add more detail to a prior submission. I am the original owner of a 2021 Toyota Highlander with 10,000 miles at the time of the issue worsening to the point that I finally broke down and was forced to pay the Toyota dealership's hefty diagnostic fee. The air conditioning system has failed due to a refrigerant leak in the rear A/C lines, specifically near the exhaust area under the vehicle. The dealership diagnosed the issue and quoted me over $3,000 to replace “all necessary components in the rear.” They offered no coverage or goodwill repair despite the vehicle’s age and mileage. Upon researching the issue for longer than a year at this point, I discovered far too many similar complaints from other Highlander owners (years 2019–2021) describing identical failures — typically rear A/C lines corroding, cracking, or leaking prematurely. In some cases, customers were told Toyota is aware of the issue but not issuing a TSB or recall. In other cases, dealers said no permanent fix exists. These repairs are prohibitively expensive and, in some reports, recurring due to poor line placement or dissimilar metal corrosion near heat sources. This significantly impacts safety in several ways: Impaired Visibility: The AC system is integral to effective defogging and defrosting of the windshield, especially in humid or cold conditions. Without it, visibility is severely compromised, increasing the risk of an accident. Driver Impairment: In extreme temperatures, lack of climate control can lead to driver fatigue, distraction, and reduced concentration, posing an indirect safety risk. I am reporting it to request NHTSA monitor the trend. This seems to reflect a possible engineering or design flaw, and the number of similar owner reports suggests it may warrant further review by Toyota and NHTSA. Customers should not be facing multi-thousand-dollar repairs on near-new vehicles with basic systems failing. Thank you for tracking this issue.

Was driving and all of a sudden ‘steering power low’ came on and engine died, got stuck in a busy intersection and needed assistance from police officer until I could be towed. Steering did not work to push car to side of the road so I was stuck in the center of the traffic. There was absolutely no lights or warnings before the steering power low and it died. Could have been very dangerous, I am supposed to drive north through the mountains to go camping in 2 days, lucky it didn’t happen then. At the mechanic now and they jumped the battery and say it’s working fine and they can’t find the problem.

The contact owns a 2021 Toyota Highlander. The contact stated that while operating the vehicle, the display screen malfunctioned and displayed a solid black screen. During the failure, several functions and features could not be accessed or activated, including the front and rear defrosters. The contact was unable to clear the front and rear windshields, which created a visibility hazard for the driver. The vehicle was taken to the local dealer, who diagnosed that the display screen unit needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 45,000.

Toyota continues to knowingly not remedy an airbag sensor issue. My vehicle has the light on indicating it is suffering from the same recall. I bought this car from them in 2024 and they sold it to me with the knowledge that there was a safety issue. I’ve tried to find a solution as this is a major safety issue. Toyota took my money in full for the car, yet can only offer me a loaner for 25 days. They said in CA, it most likely won’t get fixed until the end of 2026. I don’t have money. I have one car and I need a vehicle to transport to work and kids to school. This is not right and this is not safe. A remedy for people in CA that won’t be fixed for two more years that is an ACTUAL SAFETY issue , is not right. This is to document the safety complaint as the dealership continues to ignore the issue, and the 1-800 Toyota line continues to ignore it. All BBB complaints shows I’m not the only one. I can’t take a rental because they won’t pay me back, it’s not guaranteed, and I’m out another $40,000. They put people in impossible situations. The manager at the service center it’s your fault if you walk out of here without taking a loaner. You’re choosing to put your family at risk. And I said no, you’re offering me a loaner and you can’t guarantee a vehicle that will fit my family. I don’t know what to do.

On February 16, 2025 the vehicle was parked. The temperatures that day were in single digits. After approximately 1 1/2 hours the 12V system was drained. The driver panel was blank and the vehicle did not respond to any attempt to start. This vehicle had a similar incident the prior year, also in extreme cold conditions. During that incident the vehicle was towed to the dealership. They recharge the 12V system and did not find any problems once the faults were cleared. For the February incident, an attempt was made to jump start the vehicle. After the jump start the driver panel was active, but the vehicle reported a hybrid system malfunction and would not start the engine. The vehicle was then towed to the dealership. Attached is the report from service team. Problem #1. Under cold weather conditions this vehicle will drain the 12V system leaving the driver stranded in dangerous weather. Problem #2. The jump start procedure leaves the ECU exposed to severe damage. This leaves the vehicle inoperable.

Subject: Transmission Issue – 2021 Toyota Highlander Dear NHTSA, I am reporting a serious transmission issue with my 2021 Toyota Highlander (82,000 miles). I recently took it to the dealership for an unusual noise, and they diagnosed a transmission failure, quoting over $9,000 for replacement and service. After researching, I discovered Toyota has known about transmission issues in the 2021 Highlander since at least 2021. I have always serviced my vehicle at the same dealership, yet they never informed me of this known defect. Instead, they waited until my warranty expired to disclose the issue, despite my repeated maintenance visits where I reported the noise. I also found a 2021 Toyota document acknowledging transmission problems in this model, and many other owners have reported the same issue. It seems dealerships avoided addressing this until warranties expired, leaving owners with massive repair costs. This raises serious concerns about Toyota’s handling of known defects. I urge the NHTSA to investigate and take action to protect consumers from unfair repair costs and potential safety risks.

The Check Engine light came on and I took it into Toyota of Downtown dealership where I was receiving periodic maintenance. After 2 days, they said the light was out but they hadn't found the cause. I could either leave if for a few more days or take it and bring it back if the light came on again. This was early August. I chose to take the car & when the Check Engine warning light came on again, I took it in on Aug 15, 2024 before I left to Portland to give them more time. I returned on Monday & couldn't reach them. The next day they informed me that while on a test drive, there was a loud bang, it started smoking and by the time 911 arrived it was on fire. After a 2 month investigation by Toyota's Engineering Analysis fire inspection, they concluded Toyota was not involved. The dealership has not provided me with the report although I've requested it but they aren't accepting responsibility either although it was in their possession when the fire occurred.

The start/stop operating system failed. When the engine cut off while waiting for train to pass, the engine went to turn over and completely stopped the vehile. Although the car would not start, I was unable to cut the car off completely. It would say ignition on. The lights in vehicle were on. Running the ac caused the car to say high power consumption but there was no way to cut vehicle off without removing the battery to reset the vehicle. Caused the car to malfunction while sitting at a complete stop. Also cause the parking break to engage and I was unable to disengage parking break. A message came across saying parking break unavailable. My safety and others were put at risk because had it happened at any other time a crash would have been caused. It caused a roadway to be blocked off which caused confusion and near accidents.

The contact owns a 2021 Toyota Highlander. The contact received notification of NHTSA Campaign Number: 23V865000 (Air Bags); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was not made aware of the issue. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available. I am VERY concerned that Toyota hasn’t taken this more seriously. I notice in the NTSB website it has injuries and fatalities listed to the left of the complains. Does someone have to be injured or killed before Toyota gets their act together??? Thinking we may need to trade this for another SAFER, RELIABLE vehicle. I have also had many people flash me due to the headlights being too high and in their face-another SAFETY concern.

While depressing the brake pedal the vehicle continues to accelerate before finally slowing to a stop. This happens on bumpy road surfaces as well as level road surfaces. There were no warning lights, alarms or messages prior to or during the failure. This issue started around 35,000 mileage and has progressively gotten worse to current day. (Current mileage as of 1/29/2024 is 54,346.) This issue would cause the vehicle to potentially rear end a vehicle you are following or propel the vehicle into an intersection typically controlled by a traffic signal or device. Local dealer has said there is nothing wrong as they could not replicate the issue.

While slowing and braking to stops (approximately less than 20 mph), the vehicle will lurch/lunge forward. It feels like you took your foot off the brake pedal but you did not. This occurs randomly. It does not happen every time. There are no warning lamps, messages, etc., prior to or during this issue. The vehicle has ~39000 miles. This has been occurring for at least 20000 miles. Risk: If this occurs when close to pedestrians, other vehicles, intersections, etc., it could result in an impact.

The steering technology in this vehicle reads lines on the road that are not correct or valid lanes and almost caused several accidents during the 2 years I had the vehicle.

I came to a stop sign in my neighborhood on Windy Drive and I heard what sounded like a gunshot. I immediately put my vehicle into park and got out and noticed that the sunroof glass was shattered. The best description I can give is the glass looked like a volcano where the broken pieces were facing upward. I then proceeded to my local Toyota dealership located in Alexandria, Louisiana. They told me my car was out of warranty and provided me with a quote of $1,450.00. I believe that this occurred due to a defect from the manufacturing process and I don't think the consumer should be responsible for the cost to fix the sunroof. After researching on the internet, I see several complaints from other Toyota owners that have experienced the same incident and I feel this should be a recall on Toyota's part. I am frustrated that I have to pay $1,450.00 for damage that I know was a manufacturing defect after I researched and found hundreds of other consumers with the same experience.

We purchased 2021 highlander in March 2021. Since the day we experienced some vibration in the driver side mirror and we first notice bad vibrations when we drove above 40 to 50 mph. We never bought this up with Toyota or the dealer untill May 5th 2023. When we created a case with Toyota, they directed us to the dealer. Once we scheduled the service they confirmed the vibration and replaced Part Number: 879400E351. After the replacement we noticed that the vibrations are getting bad even during lower speeds now. The mirror is vibrating during idle and any speed higher than 30/ 40mph. We scheduled another appointment with the dealer and the manager did test drive another highlander 2022 model and confirmed that it is also vibrating. It was surprising to see that all the highlanders have these mirror vibrations. They said eventhough theres is vibration, it'd be considered normal. I rive mostly during night. The driver side mirror is blurry, vibrating and is extremly difficult to drive the car and is scary that the image on the mirror is not steady and create confusions to the driver. Changing lanes or entering to highway is really challenging as the mirros are vibrating too much and extremely hard to concentrate. This may even can cause major accidents as the image is not clear. The vibrations (humps, dips, rumble strips) are even translated to driver side vibrations and is very hard to see. The dealer even agreed to it but said that it’s a Toyota flaw in design because all Highlanders have this… and after talking to them, they said the only way Toyota would even look at this issue or have an engineer take a look in to it is if they get enough complaints or see a pattern. This is why I am reporting this to NHTSA. I want to keep Americans road safe and sound to all my fellow humans. They also said Toyota RAV4 also had these issue and Toyota issued a TSB however there is nothing on Highlander. I humbly request NHTSA to seriously look in to this and assist us.

While parking, the shifter was inadvertently left in reverse. The engine was turned off while foot was still on the brake. After preparing to exit the car and removing my foot from the brake, the car began rolling forward until I noticed and slammed on the foot brake. We are used to the vehicle parking brake engaging automatically as there is no way to do so manually, that we know of. There was no warning that the shifter was not in park and no audible or noticeable visual notification that the vehicle was not in park. In some cases, on a flat surface when the vehicle wasn't in park, it didn't allow me to shut off or arm the security system. In this case, I was able to stop the vehicle and fortunately there was nothing in front of the vehicle. Since the vehicle was powered off, anti-collision likely would not have stopped a collision.

The contact owns a 2021 Toyota Highlander. The contact stated that while driving approximately 3 MPH, the brake pedal was depressed; however, the vehicle surged over the curb and sidewalk. The contact was able to release the brake pedal, stopped the vehicle, reversed, and parked the vehicle. While driving on a hill with the accelerator pedal depressed, the vehicle hesitated and failed to properly drive forward. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The vehicle was taken to another local dealer, Germain Toyota of Naples (13315 Tamiami Trail N, Naples, FL 34110), who informed the contact about a brake issue and provided an unintended acceleration form; but the vehicle was not diagnosed or repaired. The vehicle was taken back to the original dealer who informed her about brake calibration. The vehicle was not diagnosed or repaired. Additionally, the tailgate failed to open, and the seat heaters became inoperable. The remote start failed to turn off. The windshield wipers randomly came on for five minutes but self-corrected. The manufacturer was contacted but provided no additional assistance. The failure mileage was approximately 12,000.

We rented this vehicle from Avis at Detroit Metropolitan Airport on Tuesday, 11/22/22 at approx. 7:50 pm. It was raining, cold and temperature was dropping. We drove approx. 1/8 to 1/4 of a mile from the facility. As we turned left on to a major roadway (Goddard) southbound, I turned on the rear defroster. Suddenly, the engine went into limp mode. I tried to make a U-turn to drive back to the facility. Engine lights flashed (low oil pressure, check engine, etc) and then the engine stopped. We barely had enough power to turn the vehicle out of the turn lane before we would have been struck by a bus. We sat in left northbound lane of Goddard for approx. 2 min without our hazard lights on. The vehicle would not start. I then pressed the defroster again and the engine fired up. We drove back to the facility and demanded a new vehicle. While we waited for a new vehicle to be prepared, I demonstrated to the manager what had happened. Again, after depressing the rear defroster button, the engine shut off and would not restart. Again, after turning off the defroster button, the engine started back up. This engine condition was replicated multiple times. I warned the Avis manager not to rent this vehicle as it was a death trap.

We have owned our 2021 hybrid awd platinum highlander for 8 months and within the past two months (around 16k miles) it has started to do an acceleration upon applying the brake. The car does catch itself and then after hitting the brake harder it does stop. This has happen on 7 different occasions, flat roads, hills, parking spots now. It has happened while my husband drives it and myself. It was brought it for computer recalls around the same time that this issue started. After the recalls were fixed I brought it back in and left it with the dealer for a few days. They cannot replicate it and therefor won’t do anything. They tried to tell me that I can’t drive with two feet…. Which I don’t. I’ve seen other reports where Toyota claims it’s inexperienced regenerative braking driving. We have owned a 2011 Prius that we had for 6 years and it never did it once. We also had a 2021 Audi e-from which fully relies on regenerative braking. We are not novice when it comes to hybrid driving systems. It has come to the point where I’d like to sell the car and get something else rather than worry about a car crash with my babies in the car. I also owned a 2019 awd regular gas highlander that never had any braking issues. So I don’t know what the solution is, but this is a very expensive car to be having these kinds of issues.

Recently purchased this Highlander on August 2021. On 11/29/21 at around 8:00 AM, the Check Engine light illuminated resting stop at a red light. Engine still running. Took the vehicle to the dealership at 9:45AM. Vehicle was found to have had misfires as a result of bad gasoline. I have been pumping at the same gas station ever since I bought the vehicle. If it was the bad gas, this issue should have happened sooner. Now, the dealership is telling me to pay for the diagnostic fee which they claimed it was my fault. The vehicle is under warranty. Another non-power/fuel issue that came with the vehicle was a loud wind noise when reaching 40 MPH. The noise is very annoying, like someone whistling into your ear. The dealership is ordering a part to fix this issue. The vehicle is still at the dealership.

Regarding brakes: There is an inconsistent involuntary brake pressure release occurring when slowing down via braking where the brakes let loose for about a second before applying again. This occurs with no change in pressure applied to the brake pedal. This is a dangerous situation, especially if in emergency braking situation. This has occurred multiple times over the 16k miles that it's been driven, but more recently. There is no consistency on the speeds it occurs at either. Regarding fuel: We are unable to fill fuel tank completely due to poor venting in gas tank, which could lead to spilled gas similar to overfill, causing a hazard. This vehicle has a 17.1 gallon fuel tank but we are only able to get 12-13 gallons upon fill-up at empty. Both of these issues have been reported to our local Toyota dealership, with no resolution.

I was forced to change lanes quickly from the left lane to the left shoulder of an interstate when a double tandem tractor trailer moved into my lane of traffic. The interstate was dry and the left shoulder was in excellent condition and wide enough to accommodate my vehicle easily. All lane assist options were turned off, the driving mode was set to “economy” and the cruise control was turned to “off”. A few seconds after entering the left shoulder of the interstate, I felt the rear end of my vehicle sway from side to side for a few seconds. After the swaying ended, I thought there was a brief loss of vehicle control after which the vehicle returned completely to my control. My vehicle is a Toyota Highlander Limited AWD gas engine SUV with about 2700 miles when this occurred. I drove my vehicle without any emergency steering maneuvers 2700 miles prior to and 500 miles after this incident without any problems. I had my Toyota dealer examine the suspension, steering and event recorder of the vehicle and test drive it. They found the vehicle to be performing within manufacturers specifications and without any defect in the steering or suspension and found no codes found in the event recorder.
