Windshield randomly became extremely hazy in one section to the point where Eyesight forward facing obstacle detection turned off. Cerium oxide rubbing compound was required to clear the haze enough for Eyesight to work again. Other sections have less significant haze. It appears to be hairline cracks in the outer layer of the windshield or the windshield scratches extremely easily without any obvious debris impacting it.

Windshield started cracking and crack doubled in size within a few hours, we did not hear a rock chip the window and don't know where the crack came from. Car is available for inspection. This is a safety issue as it can impede the drivers clear view of the road. Will call dealer Monday to have windshield replaced. The windshield has not been inspected by manufacture or insurance. Did not see any warnings prior to failure.

I noticed the windshield of my Ascent premium has thousands of millions of glaring specks/dots when facing the sunlight in early morning or late afternoon. The windshield becomes so blurry and extremely annoying. This happens only in early morning when facing the sun or late afternoon.

Without anything noticeable hitting the windshield, it was fine on July 2nd 2022 and when I went to get in to drive the next morning there was a crack in the windshield.

I bought a 2021 Ascent - Touring , lately there was an ever increasing amount of wind noise. It sounded like it was coming from the sunroof, but I couldn't see anything from the inside that looked out of place and there were no signs of water leaking. I finally looked up on the roof from the outside and the weather stripping along the back of the sunroof was coming out. The glue is thin, and didn't even stick to it anymore.. This is an ongoing issue. There are people people on the Subaru Ascent, Facebook Reddit forms that have said they are having the same issue..

Battery draining. Bought car from dealership preowned with 25k miles. Owned it for 3 weeks and so far -Battery dead, jumped it, good for a day then dead again. -took back to dealership, said bad battery, replaced it, good for a week and a half then dead again -scheduling to go to a subaru dealership for diagnoses Ive read about the DCM on these vehicles trying to connect to 3g towers continously even when the car is off. The 3g towers are no longer in use in the USA. Subaru should have a software update to remedy this issue but have not found that thus far. Just a lawsuit over this issue.

Aug 23, 2024

The vehicle has a parasitic battery draw. I purchased a new gel cell (Redtop) battery, the most powerful one that fits the car, and was reimbursed by Subaru. The car battery still goes totally dead after about one week, even with occasional driving. I have to carry a jump battery in case I am traveling to insure that I can get the car started when I stop.

The transmission/CVT component on the vehicle, 2021 Subaru Ascent is malfunctioning. When being driven, the malfunctioning transmission will cause the vehicle to hesitate in traffic, as well as feeling the slippage of the transmission when in motion. The vehicle also has a burning odor when being driven. NYS inspection was conducted on 10/27/25. The transmission malfunction has been confirmed by a Subaru dealer, who has had the vehicle at their dealership since 11/5/25, 34 days as of today. Subaru Advocacy , whom I have had many calls and emails with, is unwilling to replace the transmission at their cost.

The contact owns a 2021 Subaru Ascent. The contact stated while driving 65 MPH and attempting to accelerate, the vehicle inadvertently lost motive and failed to accelerate at intended. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission, and informed the contact that the transmission was slipping. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 75,000. The VIN was not available.

On Friday, June 13, 2025, while (thankfully) in my driveway, the transmission broke on my 2021 Subaru Ascent in my driveway. I simply started my car, put it in reverse, and my car jerked and stopped. NO prior warning. I was on a slight slope. I thank my lucky stars I did not have my kids out on the road when it happened. I had to have it towed to the closest Subaru dealership (a $395 charge). Upon inspection, my transmission (the CVT model) was no longer working. My car was bought in December 2021 and it has around 80,000 miles on it. In researching, I saw that the 2019 and 2020 models with the CVT had been recalled (or had their warranties extended to 100,000 miles coverage) for the EXACT thing that happened to my car. If I am correct, my car was manufactured in November of 2020 from what I was told. I find it so hard to imagine that a transmission should fail due to "no reason" at this point, my car is not even 5 years old! The fact that this has happened on cars right in the timeframe of when mine was made, it's hard to imagine I should have to pay almost $10,000 for a new transmission when the history of these transmissions failing have been quite newsworthy! It was not fixable, the only choice I was given was to buy a new transmission. In today's economy, I just find this unacceptable.

Jul 08, 2025

Every time I go out of park there is a massive clubking noise from under the car. It's actually a super common item with these cars I am seeing as well in other forums. I believe this could lead to sheared parking brakes in the future.

After 3 years the battery died completely and the car was unable to start, I replaced the battery with AAA and the next the day, it also died again. I was able to jump start the battery the next day and continued to use the vehicle. I have the battery for about a month and again the battery on the vehicle had drained where I was unable to start the car but I was able to jump start the car with a battery jump starter. There has been 3 occasions of battery just draining and I have a new battery installed. I called Subaru and they mentioned that there could be an issue with the back latch no closing which could drain the battery, however, the have confirmed that the back door does completely close and lock or it will just automatically come back up. I feel there is something wrong with the electrical system and AAA has confirmed with me the the alternator or the battery is functional.

Blue smoke from tailpipe upon start

Jul 17, 2023

Windshield is extremely soft and cracks easily. In less than 1.5 years I've owned the car I've gotten 3 chips/cracks and now a 4th major one that requires a full replacement. No car previously owned ever had this issue, not even the previous Subaru. After searching online this seems to be a common problem in Subarus, as there was a class action suit for earlier models. Yes, car is currently available for inspection until repaired. Super soft windshield - if the windshield is broken completely on a highway, it's obviously a concern and a risk. Have not taken the car in yet, but will be to get it replaced.

April 25, 2022: The trunk/liftgate of the vehicle failed to detect an obstruction and closed without retracting when it came in contact with an individual's head. The impact caused a head injury, blackout, and concussion, and resulted in permanent damage to an individual (6' 2" - 190lbs). Subaru’s stated that an inspection of the vehicle was performed on May 19th and informed me that “the vehicle is operating as designed…and has met all federal specifications,” and that their inspection concluded that this is “no manufacturing defect.” Prior to the inspection, Subaru requested signed consent to inspect the vehicle's internal data which I provided. When I requested a copy of the report, Subaru informed me of their policy not to share this information despite the vehicle "operating as designed." One of the first things that we learn about computers is “Garbage in, garbage out.” My position is that if Subaru’s computers are not programmed to look for issues pertaining to incidents that contradict their message of superior safety features, then their computers will not find issues that do not reflect their preferred image. No warning messages or symptoms prior to this occurrence. Subaru's response is included in this report.

SERVICE BRAKES

Brakes shudder and fade when slowing down from highway speeds. Subaru has issued many "fixes" but it keeps happening. See most recent "Ascent Front Brake Warranty Extension Coverage" it still has not fixed the problem!

Sep 25, 2024

Brake rotors, front and back warp. Rotors have been replaced and resurfaced multiple times. The vehicle is over-sized for the braking hardware included with the vehicle. I have spoken to the dealer multiple times and they are aware of the undersized brake component issue across this model line. Although promised, Subaru has not addressed the issue and it is a safety hazard in hilly terrain.

Jun 27, 2024

Started having problems with the brand new car shaking and brakes making grinding noises when stopping around 20K miles. Brought the car to the dealership and they ended up replacing the brake pads and rotors. It’s been just over a year and less than 15K miles since the replacement and the car started shaking and brakes are making a grinding noise again. Again took the car to the dealership and the rotors are bad. After further research, this is a constant and known issue and has yet to be resolved by Subaru. Instead they wait for the new car warranty to wear off and let their customers pay out of pocket to have this fixed. Some owners have had to replace up to 4 times in less than 40K miles.

May 11, 2024

Front brakes (pads and rotors) had to replaced 2 times. The dealer said that Subaru used undersized pads and rotors on the bigger Ascent model. The brakes were not designed for such a big vehicle, and it has been a known issue. The brakes were replaced under warranty, but my warranty will expire soon. I'm stuck replacing and poorly designed braking system, that is a known issue.

Apr 05, 2024

Vehicle braking reduced to about 10%. Brakes was making lots of noise and couldn’t stop for almost 1/4 mile. Managed to stop vehicle was taken to dealer. Calipers were changed and rotors serviced. After several trips to dealership for repairs to brakes vehicle still having braking noise and reduced stopping power which gets worst with time.

STRUCTURE

The windshield on the 2021 Subaru Ascent is dangerous because it chips extremely easily. I purchased the car new in 2021 and since then I have had 7 rock chips (in all different states (TX, CA, WA) and driving conditions/speeds/roads). In the 4 years since I have owned it I have had the windshield replaced twice so I am on my 3rd windshield. Each time the rock hits, it causes a large chip to form which distracts the driver momentarily. It also creates defects in the windshield which could lead to safety issues of the windshield shattering.

Apr 04, 2025

I noticed that the driver's door was making an odd clicking sound when the door was closing. Upon further investigation, I found the silver door bolt holding the door to the frame was loose. I have since then had the bolt tightened.

Hello, my vehicle 2021 Subaru Ascent Limited with Navigation Package had it's panoramic sunroof cracked while the vehicle was parked in the garage. Upon researching the internet, it appears that this issue is systemic design or material flaw for Subaru vehicles.

LANE DEPARTURE

4 complaints

Vehicle drifts on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer; they did a calibration of the eyesight. The problem still persists, especially when driving the vehicle on the highway. This has almost pulled me into traffic on a few occasions!

Apr 05, 2024

It is actually the lane centering system. Even a gentle hand on the wheel, which is required, will gradually pull you to one side of the lane. When ever you lift your hand or when the car thinks you have gone to far one way or the other it will throw you into the other lane, into a car, motorcycle, semi, or even off a cliff. This system is so dangerous I cant believe it hasnt been recalled. If using this you will get thrown one way or the other several times during most trips. Dealer states its normal and I got that in writing.

May 03, 2022

The car constantly over-corrects when it tries to keep me centered in a lane on the highway. It always over-corrects to the left shoving me to the left into the adjoining lane, and potentially side swiping vehicles in the adjoining lane. It never over-corrects to the right. I reported this to the dealer and I was told that this is normal.

Nov 17, 2021

The lane keeping assist pull abruptly into the other traffic lane when traveling on the highway for example when on a 4 lane road with two lane in the same direcstion and passing a semi truck the steering assist abruptly pulls the car into the truck's lane and requires immediate hard handed reaction to keep the car from hitting the truck. The lane assist on this subaru vehicle is more dangerous than it is helpful. Subaru is terribly un response to request for help although the car is less than 1-year old and has a mult-year extended warranty---subaru's customer service is the worst we've experienced. BTW my son's Honda Acura's lane assist is excellent!

Vehicle wanders on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer, did an alignment and took it back a month later because the issue persisted. The problem persist, specially when driving the vehicle on the highway. I am really concern about my family safety and the safety of others in the road.

THE 2021 ASCENT HAS LANE CENTERING ASSIST WITH VERY STRICT MARGINS. IT IS A CONSTANT TUG OF WAR WITH THE VEHICLE WHEN LANE CENTERING IS ACTIVE. WHEN YOU LET THE CAR TAKE OVER, IT VIOLENTLY JERKS YOU INTO THE NEXT LANE. THIS PROBLEM HAS BEEN CROSS CHECKED WITH OTHER USERS ON A SUBARU FORUM AND ALL HAVE THE SAME ISSUE. THE CAR OVERCORRECTS AND IS PRONE TO CAUSE AN ACCIDENT AT SOME POINT. I AM LUCKY NO ONE WAS IN THE LANE NEXT TO ME WHEN THE CAR SWERVED ME INTO THE NEXT LANE. MY 2021 IS A REPLACEMENT OF A 2020 MODEL BECAUSE THE 2020 WAS DEEMED A LEMON. THE 2020 MODEL DID NOT HAVE LANE CENTERING BUT LANE KEEP ASSIST INSTEAD. THE 2020 DID NOT VIOLENTLY JERK INTO THE NEXT LANE. THIS ISSUE HAS BEEN REPORTED TO LESLIE KARPIAK AT SOA WHO HELPED ME THROUGH MY LEMON ISSUE ON THE 2020 MODEL. I REQUESTED A FULL BUY BACK AND SHE SUGGESTED I HAVE MY CAR INSPECTED AT A DEALERSHIP, BUT THAT IS A LENGTHY PROCESS AND I HAVE ALREADY SPEND 3 MONTHS IN AND OUT OF DEALERSHIPS WITH MY 2020 MODEL. THIS APPEARS TO BE A COMMON ISSUE ON ALL 2021 MODELS AND SHOULD BE INVESTIGATED FULLY. I AM HOLDING SUBARU 100% LIABLE WHEN AN ACCIDENT OCCURS BECAUSE OF THIS LANE CENTERING ISSUE. THIS ISSUE HAPPENS ON A CONTINUOUS DRIVING BASIS. YOUR HELP AND ASSISTANCE IS GREATLY APPRECIATED FOR THE SAKE OF SAVING LIVES.

VEHICLE WANDERS ON THE HIGHWAY. WHEN PASSING A VEHICLE ON THE ROAD THE LANE CENTERING ASSIST TRIES TO HUG THE CENTERLINE AND THE DRIVER MUST KEEP PULLING HE VEHICLE BACK TO THE CENTER OF THE PASSING LANE. A SHORT LAPSE OF STEERING COULD PULL THE VEHICLE INTO THE SIDE OF THE VEHICLE BEING PASSED. FULL TIME JOB TO KEEP THE VEHICLE FROM WANDERING WHEN VERY LIITLE WIND AND ALMOST IMPOSSIBLE TO KEEP IT FROM WANDERING WHEN THE WIND IS BLOWING 15-20 MPH. NOT A PLEASANT RELAXING DRIVE.

Vehicle smells of fuel inside the cabin and when parked in the garage. To date the dealer is unable to diagnose the problem. 60k miles

Dec 26, 2025

The contact owns a 2021 Subaru Ascent. The contact stated while driving at 65 MPH, the vehicle shut down completely. A message indicating that the vehicle had unexpectedly stopped, and to check the vehicle as the remote start had failed was displayed. The contact was able to veer to the side of the road safely and waited until the vehicle cooled down. The contact restarted the vehicle and continued driving. The vehicle was taken to the dealer where it was diagnosed that no issues were found. However, the failure reoccurred several times while driving. The vehicle was not repaired. The manufacturer was contacted and informed the contact that they could not assist as the dealer diagnosed that no issues were found. The failure mileage was 300.

Oct 12, 2022

I found a lot of oil leaking from the oil filter cup and that would splash all around the filter area. I brought the car at the dealership and they have replaced the filter but when I checked after few days ( smoke was coming out of the hood) there was oil all over again. I bought an aftermarket filter and I installed it myself. No one drop of oil found. So I believe this a is a safety concern because the oil might catch on fire with the heat of the engine. I believe a defective oil filter design or a bad technician training or both are causing the problem.

I was driving along with no traffic in front of me and no oncoming traffic when the automatic braking system engaged with no vehicles in front of me, this was at 7:42 AM on Monday August 12, 2024. This was not the first time it had done this, but the first time I had the time and no traffic anywhere around to confuse the system.

The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.

2021 Subaru Ascent with 15,735 miles on it with the factory Falken tires. The tread and metal was showing and separating from the tires. 2 tires, original to the car off the lot. Tires should last 30-40-50 miles. The other 2 tires were labeled as a 4-5 category. The car did not steer to the left or right, no noise at all. If driving on the highway and 2 tires failed, I could have been injured, my passengers or another vehicle crash. This was very dangerous. In going to the Subaru website and seems hundreds of other customers had the same issue. Failing, inferior, defective Falken tires and alignment issues. I hope these tires don't fail and cause someone to lose their life.

Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Eye Sight, RAB, some ! Symbol, and check engine light are all on and not working. You know everything that makes a Subaru. This is not the first or even second time. We are on the fourth instance of this happening. We live 2+ hrs away from the closest dealers. The first few times it occurred, we called to make a appointment. Each time was always a few weeks out and the issue would clear a day or two before. This last time has been going on for 6 weeks. We both work full time and have a very sick kid so making a appointment is hard. This last time I asked if I can drop in just for a scan due to being in town for an appointment. Was met with we are backed up with way to many repairs. Also it would not be fair to any other people. It is most likely your gas cap. I have made sure the cap is tight as it can get every time from the first time it occurred. So all safety features on the Subaru Ascent just stop working if the cap is not tight. Not only is this a major safety issue their QA is asleep at the wheel. Known issue, just check the forums.

SEATS

1 complaint

Purchased 2021 Subaru Ascent Limited outright, drove it for few months, started having pain in my right thigh that resulted in cramping and severe discomfort which affected my ability to feel the break pressure. This nearly ended up causing a couple of near miss rear end collisions. The pain got so bad that it caused me to lay prone and apply muscle cream to the affected area then remain prone for like 15 minutes before being able to continue driving until the pain returns. I consulted my Doctor and went through all the hoops to get an MRI, steroids, pain meds, heating pads, etc, without results or elevation. Ive tried cushions, padding and every possible seat adjustment still without any relief. I am scheduled for surgical consultation over this matter with strong possibility of surgery. There are thousands of Subaru owners throughout the web suffering from this same issue which has been medically classified by physical therapy professionals as " Subaru Sciatica Syndrome". The poorly designed seat has hard bolsters that jam into my thigh causing the sciatic pressure that causes the abnormal break pressure sensation. Therefore meeting two requirements for investigation. Subaru USA is aware of this problem and has banned me from posting anything educational on all their websites informing owners to the solution and action available. I had the seats looked at by an experienced car upholstery shop and repairs were estimated, submitted to Subaru upon their request, only to be denied.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,LANE DEPARTURE

1 complaint

My mirror on my car has started melting. They told me it was a outside force, from a lighter. I told them it was electrical or something wrong from the inside of the mirror. There are forums recently posted up regarding this and Subaru has ignored them all claiming it is reflective light from the sun. That they can’t do anything about it. Others have replaced their mirrors 3 times now. This is a potential fire hazard and could be unsafe. They are not addressing this as it should be. https://www.thesubaruforums.com/threads/melting-side-view-mirror.12397/

ENGINE,FUEL/PROPULSION SYSTEM

1 complaint

Unknown. I am smelling gasoline in the cabin of the car. A LOT of fumes fill my garage when I start the car. The car sometimes accelerates when I put it in park, resulting in more fumes. Fuel efficiency is lower than expected as well.

FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

1 complaint

THE LANE ASSIST FEATURE (ONLY AN OPTION WHEN USING ADAPTIVE CRUISE CONTROL; NOT THE SAME AS LANE CENTERING WHEN NOT USING THE ADAPTIVE CRUISE CONTROL [THE BASICS LANE CENTERING WORKS JUST FINE]) SEEMS OVERLY AGGRESSIVE. EACH TIME I HAVE USED LANE ASSIST WITH CRUISE CONTROL, IT JERKS THE CAR VERY ABRUPTLY AT TIMES, ALMOST TO THE EXTENT OF SENDING IT INTO ANOTHER LANE IF I DO NOT INTERVENE. I NO LONGER FEEL SAFE USING LANE ASSIST, SO I TURN IT OFF WHEN USING CRUISE CONTROL. I AM VERY CONCERNED IT'S GOING TO CAUSE AND ACCIDENT. THIS HAS HAPPENED AT LEAST 5 TIMES NOW WHILE DRIVING ON THE FREEWAY (EVERY TIME I HAVE ATTEMPTED TO USE LANE ASSIST).
