NHTSA Recall Number 22V354000 has been active since May 18, 2022. The dealership says no dealers in the area have received the part to fix it. The recall itself carries serious safety concerns as the seatbelt will explode metal fragments in an accident. The dealer has also told me that 35 other people are waiting for the recall to be fixed as well. This is ridiculous, Hyundai needs to get these parts to the dealers.

FORWARD COLLISION AVOIDANCE

18 complaints

The Forward collision warning light comes on randomly at times and disables the system. It’s done this on 3 occasions. No one has inspected the vehicle. I was told everything was normal. No injuries involved. The problem has occurred 3 times now with code c1620078. The history codes show this has happened to the previous owner as well. I bought it in 7/2025 and it happened driving it home from buying it, in 11/25, and 12/10/25

Dec 11, 2025

Forward sensors in vehicle have been failing while driving rain or snow since 2021; would go way on its own. Most recent failure has occurred with no debris or obstruction to sensor on a clear and sunny day. The sensor failure has been stagnant and will not go away, increasing a safety concerns while driving.

Sep 19, 2025

Front sensor problem. Sensor Check Forward Safety System. ABS, Auto Hold light came up out of no where. No damage to sensor.

Jun 04, 2025

Radar equipped to front of vehicle has malfunctioned, disabling all forward safety systems and adaptive cruise control. Without this equipment functioning, cruise control is completely disabled and the vehicle will not automatically brake or provide forward warnings. The vehicle component has not been inspected, but this is a recurring issue amongst other owners of this model. There is a warning lamp that turns out that states "Check Forward Safety System"

Nov 22, 2024

Several times, including yesterday, my forward collision avoidance engaged by braking suddenly and strongly and INAPPROPRIATELY, almost causing me to be rear-ended. I was nowhere near the car in front of me, and fortunately due to traffic was traveling below the speed limit. This seems to happen whenever there is an overpass above the road. I have reported this to Hyundai, and they don't seem very concerned. Very dangerous. I would think there could be a software or sensor update that can correct this situation.

Odometer Fraud. The contact purchased a 2021 Hyundai Elantra. The contact stated that it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the mileage was 51,192 and at the time of receiving the vehicle from the dealer it was discovered that the mileage was 50,310.

My back up camera fails to work consistently. This issue appears to only worsen with every use. Sometimes to screen will appear half on and half off. I have yet to receive any notice of a recall and would like to get this fixed if at all possible. Thank you!

The reverse camera does not work

Dec 25, 2024

I am writing to file a formal complaint regarding a significant safety issue with my vehicle’s backup camera system. The backup camera consistently malfunctions, displaying glitchy images with distorted lines across the screen. This issue renders the camera essentially unusable, as it fails to provide a clear view of the area behind the vehicle, posing a serious safety hazard. This malfunction directly impacts my ability to safely reverse, especially in crowded areas where visibility is crucial. The camera’s unreliability puts pedestrians and other drivers at risk, as I am unable to fully ensure that my path is clear when reversing. I strongly believe this defect poses a significant safety concern that needs to be addressed by the manufacturer. I request that the NHTSA investigate this issue and take appropriate action to ensure that this problem is resolved for myself and the many other affected vehicle owners. Thank you for your attention to this matter.

Oct 21, 2024

Since last year around 55k miles, my backup camera has stoped working. The first incident happened as I was about to back out of my garage. I opened the garage door and put my car into reverse. As I looked down at the screen and began to back up, I realized the screen showed me an image of a closed garage door ever though the door was open. Almost as if it had taken a screenshot or froze. The second occurrence was similar except it was when I was parking in a job site parking lot. When I put my car in reverse to park, what came on my screen was the image of the highway about 15 minutes prior. I’ve had several experiences like this where the backup camera freezes, has static-like lines all over the screen, discoloration, or delayed effects. This is dangerous because if someone is looking down at the screen and doesn’t realize the backup camera is giving an incorrect output, this can result in an accident (whether it be a single car or multiple car accident). This is because you can end up hitting something/someone if you get delayed feedback on the camera and don’t realize.

The horn does not work. I've been out of a horn for the last 4 1/2 months. The horn fuse blows every time I replace it and if I use the horn it blows. Now I replace the fuse and the horn still doesn't work on this vehicle

Apr 11, 2025

The horn is a known issue to stop working on the Hyundai Elantra. I have had my car for 10 months, and the horn does not work. This is a very big safety concern and I have been told by mechanics and other Hyundai Elantra owners this is a constant issue.

Dec 08, 2023

Two matters: 1) The recall notice "Campaign 216" regarding my 2021 Hyundai Elantra has not yet been remedied nor has Hyundai announce a timeline for a remedy. It is regarding the windshield. 2) Secondly, my horn stopped working 100% and I took it to Hyundai last week and they said a lot of 2021 Elantra's were coming in with broken horns. They ordered me a brand new part that seems as though they redesigned the horn system. It will be replaced this week. I asked if I missed a recall and they said no, the horn problem has not yet required a recall but they seemed to suggest that the horn issue is a real matter effecting their Elantra's. I would hate for other 2021 owners to suffer a horn failure when they actually need it in a real life safety situation. The horn just stopped working. The horn is a safety function and if that is broken what can one do in an urgent matter "yell", not likely. No warning ahead of time...just one day it stopped working with no indicators.

Wireless Apple CarPlay frequently disconnects at random during drives. I’ve got the latest iPhone update, done every reset in the book, and spoke with my dealership and there is NO solution. It is also impossible to use a wired CarPlay function despite a data-USB input. It is a totally unnecessary move to force users into using this failure of wireless technology. The screen will frequently black out for an extended period of time creating a challenge if you are following the navigation. Additionally, you must tap through 3 warning pages before being able to access the streamed maps or other content again. It is distracting, unpredictable, and continuously more frustrating as neither Hyundai nor Apple have provided a solution that works and instead resort to a “blame game” of each other. Furthermore, both companies act surprised when hearing about this issue, but a quick Google search shows many users struggling with no solution in site! This started the week I bought my car (brand new) and has only gotten worse since.

While Driving the car suddenly turns off. It puts me at risk because if I am in a situation where there are other cars, I can be hit and undangering my life and others! This problem happened suddenly and the car restarted only to fail again,multiple times. Towed to dealer /Danbury Hyundai and they claim not to find problem. The car had a full tank of fresh gas. This happened without warning.

The contact owns a 2021 Hyundai Elantra. The contact stated that there was a knocking sound coming from the engine compartment while the vehicle was idling. The RPM fluctuated and the vehicle stalled while at a complete stop, and while shifted to park(P). The contact restarted the vehicle and was able to continue driving. The check engine warning light was illuminated. The failure had occurred intermittently. The vehicle was taken to the dealer, who confirmed that the 2.0L engine was known for similar issues. The dealer confirmed that the VIN was not included in NHTSA Campaign Number: 21V301000 (Engine). The vehicle was not diagnosed due to a lack of diagnostic trouble codes being displayed. The vehicle was not repaired. The manufacturer was informed of the failure, and a case was opened. The failure mileage was approximately 127,000.

Feb 21, 2025

The contact owns a 2021 Hyundai Elantra. The contact stated that the vehicle was taken to the dealer for an unknown recall repair and for an oil change. However, while driving at an undisclosed speed after the services were performed, there was smoke coming from the exhaust pipe and the engine oil warning light was illuminated. The contact noticed that the engine oil had leaked onto the roadway while driving. Upon inspecting the vehicle, the contact noticed that the engine oil drain plug was missing. The dealer was made aware of the failure but provided no assistance. The vehicle was then taken to a second dealer, Columbia Hyundai (10981 Montgomery Rd, Cincinnati, OH 45249). However, the vehicle was not diagnosed or repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,500.

At about 11 months old my car suddenly seized while attempting to enter the highway. This came with no type of warning from the vehicle until the car had stopped and then every light on the cluster came on. I was fortunate not to be rear ended. The car was towed and 2 days later the dealership called to tell me there were no errors and NOTHING WAS WRONG with the car. I told them what had happened and they called later that day and I was informed that they needed to install and entire new engine assembly. The car only had 7000 miles on it and should not need a new engine. There is some major design flaw with this car which poses a safety issue. Additionally I looked at my service records for the car and it looks as if the dealership is trying to cover up the fact that a new engine was placed in the vehicle as it is listed as routine maintenance. Please look into this and contact me if needed

On 1/27/2022 my daughter was driving home from school in her 2021 Hyundai Elantra SEL which was purchased new on 6/19/ 2021 when at 5600 miles on the odometer a message came on the instrument cluster which read put car in neutral and turn off engine, when it was safe to do so she stopped the car and turned it off in the middle of a two way road because there was no shoulder and no place to exit the roadway when she tried to restart the car the engine would not crank or turn over to start the car so she called me and I called a tow truck while she was waiting vehicles behind her where forced to go around her car when it was safe for them to do so, the tow truck came and took her car to the dealership where she purchased it two days later they called and informed us the engine was completely seized up and that they would have to replace it with a NEW ENGINE despite the fact the original engine had oil and was only six months old with only 5600 miles on it.

VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

5 complaints

One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

Jul 20, 2024

Driving on highway, dashboard reported "Check Forward Safety System" and "Check Smart Cruise Control System". The car then disabled both while I was driving. This has happened 6 times to me. The first time I brought it to dealer and they stated it was a calibration problem. They reset it and I had no problems for a while. The problem has occurred 5 times more and will stay on for about a week or so and then just go away. It works again and then occurs again. So, it is intermittent and recurring. Each time the diagnostic code reported by the software to my phone is C162078. I see the 2018 Kona had the same exact problem and a software update TSB was put out there.

The forward collision warning stopped working several months ago. We gave the (leased) car to the dealer for repairs after 4 weeks of waiting (parts, etc.) We were told the car was fixed and ready for pick-up. I drove it from Baltimore to DC for a meeting and on several occassions when car stopped abruptly in front of me on the highway it did not give a warning, when I tried using cruise control, it would not engage because the conditions for doing so had not been met - same message I had when foward collision was not working. It's pretty clear that this was not fixed and instead they must have changed the messaging so that it does not appear as a warning when you start the car. The feature is really important to us because it has prevented a potentially fatal accident on a winding road in NY state where we found a truck on our lane due to a downed tree on the other lane - the car braked well before I did- which is the point of these safety systems. The dealer is Len Stoler Hyundai in Owings Mills

I have had to get the horn replaced on my ELANTRA six times the horn goes out and this can be a very big safety hazard as it has caused people to almost hit me because they didn’t see me and my horn wasn’t working to alert them this needs to be addressed as soon as possible as this could cause someone to lose their life in the wrong instance

car problems started with back up camera not working, it has caused dash lights to go out, headlights to go out while driving safety sensors to sound for no reason. I have also started having problems with radio flashing and going blank. The vehicle has been checked by Hyundai dealer they did say back up camera bad but no answers for rest of issues.there were no warning lights prior to any of these problems. I still do not know what is really wrong and cannot drive vehicle at night or bad weather for fear of losing headlights. Vehicle is 2021 hyundai elantra with 10,500 miles on it.

The windshield is damaged very easily when a small rock hits it on the road. It's been hit before the recall and the new windshield is damaged. It's a hazard especially if it can be easily cracked. I've had other vehicles that can handle small rocks on road ways. These are damages from tiny rocks. This windshield is very weak, the Crack continues to spread all over day to day.

Engine shots off while on the automatic stop and go idle . It is being doing it for a while but it is happening more often even with the auto idle off and it even happened at the freeway. It gives me a message to put it in park or neutral and turn the engine on manually. Making this a very dangerous situation because cars behind me don’t know that my engine suddenly shots off. Thanks

Oct 25, 2023

Driving headlight output is so diminished that it is very difficult to safely drive in adverse conditions, ie., darkness, rain and oncoming vehicles. The projector lamp assembly used in this vehicle is old technology and is somewhat compounded by the use of a smoked acrylic outer lens cover assembly. I feel that safety was compromised for style and this is not acceptable. I have sent a letter to Hyundai Motors Customer Care dated Sept. 7th in this regard asking for a Hyundai sanctioned solution and authorization for selling dealer to correct situation

The Horn never worked since I bought it in August 2023, i’ve been in a countless near accident situations where I was rendered helpless. I’ve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the ALM dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasn’t guaranteed that the issue would be fixed.

Unintended acceleration is happening. After about 15-30 minutes of driving, accelerating from a stopped position becomes very difficult in the sense that the vehicle does NOT accelerate when gas pedal is pressed. This can be extremely dangerous as you do not know when the vehicle will no longer accelerate and could get hit when crossing an intersection or turning onto any road at all. ESC warning light came on today and vehicle will no longer start but goes into auxiliary mode. This is not the first time, second, third, nor even 5th time a report on this vehicle has been made and with each report more issues are arising with seemingly NO fix in sight.

My car has two warning lights on my dashboard. First one is Check Foward Safety system. Second one is Check Smart Cruise Control System. Both of them turned on when I was driving in the middle of a highway. These warning lights activated out of the blue, without any unusual circumstances.I cannot use my smart cruise control system and the car is not able to alert me about forward collision. This issue has already been addressed through a recall for my vehicle's model and year in Korea. My vehicle was produced in Korea and was imported to the United States; however, Hyundai has not issued a recall regarding the same problem in the United States. This is a safety concern, and Hyundai should repair it free of charge, and the company should compensate customers who have already undergone repairs for the repair costs.

The horn stops working. It is not a fuse related issue. It is the horn itself. There are multiple reports of horn failure in this model, 2021 and 2022, on the internet and social media. There are people reporting that dealerships are also seeing a lot of cars with horn failure. This is a serious safety issue. Someone could go off the road into the woods and crash, unable to signal with a horn that they’re there. Unable to beep their horn to get the attention of a child or animal that is about to run into the road. There are countless scenarios where the horn is important. Cellphones don’t work everywhere… a horn should always work. There are far too many reports of the horn issue for it to not be a manufacture related issue. Please look into this. This could have pretty tragic implications that could otherwise be avoided. I will attach a screenshot from a social media Hyundai group of the 2022 model. I need to get into the dealership to have mine repaired and will do so asap. I’m just very concerned about the safety of everyone. Some are reporting dealerships are not clear about if the horn issue, which involves replacement of the steering assembly, is covered, while others are saying it is.

I completed an oil change at Greggs oil express in Porterville California on 02-11-2023. I have the invoice. On 02-24-2023, I went out of town. At approximately, 5:00 pm, I heard a loud bang, large amount of oil pouring out of the bottom of the car, the car became disabled and I pulled over to the side of the road. I had it towed to the closest Hyundai dealership in Victorville Ca. They provided me with a report that stated when receiving my oil change stating due to the drain plug issue is a direct result of a third party and was not covered under warranty. I then made contact with my insurance, an investigator also reported the same. I have both reports. I have made contact with Greggs Express where I received the oil change and it was suggested to report the incident as they have come across situations like this with the particular vehicle. Therefore, I am now stuck. It is not covered under warranty, not covered under insurance, and the cost is 10,000. Besides the fact that I could have been injured.

I picked up my Hyundai Elantra n-line today 12/1/22. My car was at the dealership for almost 3 weeks for transmission judder (shudder?) issues and they claim to have fixed the issue with a TSB (Technical Service Bulletin) from Hyundai with some snap and cable and additional work that was not disclosed. After picking it up and driving only 3 blocks my car went berserk where all dummy lights went on, the car's engine revved to redline, took off and suddenly the front wheels turned left (due to the avoidance features of the car perhaps) and I was able to pull the emergency break and stop the car. The car stopped luckily and if the e-brake did not work I would have ended up hitting the rear corner of a car and into a house. While the car was stopped, it was still on (unable to be turned off), all lights blinking including dummy lights and the car was showing still in DRIVE mode even though the revving stopped and the car was dead stop. After 10 minutes I was able to turn the car off (push button). Dealership dispatched a tow truck and now my car is back at the dealership for investigation. NOTE: TSB is something that is a known issue from Hyundai but not yet to the level of an official recall is what I was told by the dealership.

On February 23, 2022, I was involved in an accident with the Hyundai Elantra, Vin# [XXX]. The vehicle’s brakes failed, and I struck a Blue Ford Escape from behind with a speed of approximately 37 mph. On January 13th, I made an appointment with the Napleton Valley Dealership in Aurora, IL. where the vehicle was purchased complaining about the brakes and drifting into an intersection on Route 83 and Sycamore Rd. for 20 feet. The mechanic checked the brake pads, drove it for 3 miles and deemed that the vehicle’s pads were adequate. It was determined that no problem was found, brakes checked good, all within specs. (12,818 miles). The vehicle was towed from Hinsdale, IL. to Dekalb, IL., approximately 85 miles to my residence at 612 Magnolia St. Dekalb, IL. 60115. It was then towed a distance 3.2 mile to Dekalb Body and Collision, 116 Industrial Dr., Dekalb, IL. 60115. Since then, it has been back in the dealership for issues related to the engine, taillight, and a series of additional Inspections verifying that the codes were working. On March 8th when I visited the Body Shop & Collision I was told to “hire an attorney”. The vehicle was defective and should have never been on the streets. Preliminary findings on vehicle were concerning as far as airbag sensor was impacted but no airbags deployed at the time of impact. Upon vehicle arriving at our repair facility, we conducted pre-repair scan vehicle codes read as followed (see picture). Impact sensor was highly damaged, expected to have had airbags deployed at the time vehicle was impacted. Vehicle received front-end damages which resulted in needing the following parts replaced, front bumper and grille. Crash impacted the front bumper reinforcement resulting in some hours needed on frame machine to align front-end. Engine cooling system was impacted resulting in the need to replace radiator assembly and A/C condenser assembly. Hood and both front lamps are needed to be replaced as well. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Hello everyone. I NEED HELP i have a 2021 hyundai elantra and i have had the same issue for over 10k+ miles and 6 months. My traction control light, (no matter what speed or acceleration/deceleration.) will flicker on and off, make a horrible noise almost as if the ABS is applying but no ABS light comes on, and the pedals will go stiff and the whole car jerks. My 2021 elantra has had a new transmission put into it AND when that didn’t fix the issue, the wheel speed sensor was replace… well if that had fixed the issue, i wouldn’t be writing this post. after a new transmission, and wheel speed sensors, didn’t fix the issue the dealership themselves advised me to look into the lemon law being they had no idea at this point what was going on with my car. i have attempted getting my car bought back under the lemon law (Ohio) which my car meets the qualifications being that the issue was brought the the dealerships attention, before the 12 month or 18k (whichever came first) which in this case was taken to them before both. and that my car had been in the shop more then 30 days cumulative (it’s been 41) and hyundai has denied my request for a buy back, and has told me i need to do more research or get an exterior 2nd opinion. (pretty much a lawyer). they’ve advised me to “just keep taking it to the shop and get it fixed”. the issue is, this does not occur all the time. it is completely random and will do it once in a week and then not again for another 3. but when this happens, it’s scary. it’s loud, the pedals go stiff and the whole car jerks. accelerating or decelerating. the dealership will not replace something if they cannot duplicate the issue which is also a reason it’s taken so long to get any sort of answers. i have multiple videos, the service MANAGER, has rode in my car with me while this issue has occurred and stated himself my vehicle is unsafe, and i should not be driving it. i need help!

My vehicle was slowing down and was halfway into a parking spot. Then, it suddenly accelerated, jumped over commercial parking blocks, and ended up stopping after hitting a wall. My brake was not working at that moment. I initially reported it to Hyundai USA (as a dealership doesn't seem to consider this a serious issue at all), but decided not to let them investigate on their end based on their slow and unprofessional responses.

STEERING,SUSPENSION,SERVICE BRAKES

1 complaint

The car was brought back to the dealership after a few months after noticing that the steering wheel would shake and the car would jerk when brake was applied to slow down. In normal street driving as well as during highway driving. The dealership since it was under the warranty replaced the front rotors and the brake pads to solve the issue. Within the one year of purchase of the car, it was once again having the same issues of steering wheel shaking and the car jerking motion back and forth. When he car was brought back to the dealership they said that it was not under the warranty and that they would not address the issue And that if i wanted it to be fixed i would have to pay out of pocket I think that there is something wrong with either the rotors or the braking system that is casing this shaking and the car jerking when trying to slow down, and it should be addressed and investigated further.

UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE

1 complaint

In the middle of crossing the Verrazzano Narrows Bridge in New York City, the forward collision warning came on and the braking system automatically engaged REPEATEDLY. I was traveling about 30 MPH and had about 4 car lengths between my car and the one in front. The system kept engaging no matter how much room I put between myself and the car in front of me, and as I was in the middle lane of a bridge in heavy traffic I could not pull over. I always keep a good distance in front when driving, but because of the system inappropriately engaging I almost got rear-ended about four times. I was terrified and this continued to happen until I got off the bridge. I use my car mainly on the weekend, and also travel this bridge almost every weekend and this was the first time this happened but it was terrifying and EXTREMELY DANGEROUS!!!!

STRUCTURE

1 complaint

The hood of the car is clearly larger and "off-kilter" with the rest of the body (and front grill) of the car. Although the body indentations match, the hood looks as if it were from a completely different model. It also shifts down on the driver side of the vehicle giving concern that it may shift further and get damaged. A clear manufacturer defect and safety hazard. After the dealer told me they could do nothing, I opened a case with Hyundai Motor. Hyundai Motor has failed to reply or report back on a resolution. Initial report was made on 5/13/21 and a case # was assigned (case manager assigned on 6/5). As of today, 6/9/21, Hyundai Motor has not yet contacted me for a resolution. I am concerned about driving my vehicle if it causes the hood to shift even further and causes damages, detaches, bumps up against the front grill, or causes an accident.
