2021 Subaru Ascent owner complaints

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..

The contact owns a 2021 Subaru Ascent. The contact received notification of NHTSA Campaign Number: 22V907000 (Electrical System) 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 manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

The moon roof/sunroof has leaked numerous times. The dealer has tried to fix it on three occasions. It continues to leak- it leaks water into the front eyesight cameras causing them to not work & cut off sporadically. The water leaks into the cab causing the headliner to be wet, the floorboard and the entire console and cup holders fills up with water. I have had it at the dealership on three occasions dec 2012 jan 2021 nov 11 2022 and it has now happened a 4 th time on nov 15 2022 and is still not repaired. I have been without my vehicle for 34 days. It has less than 18,000 miles on it.

Car would not start in morning. @20,000 miles. Battery dead..not even trying to turn over..Had to get car jumped then all safety features went dead..looked on Subaru sight and it showed every safety feature disabled..I did not drive car till next day to bring to dealer..next day all features fine like nothing happened..Dealer found nothing wrong. Dealer tested battery and showed fully charged..

The battery constantly drains when the car is not in use for a very short time. It appears to be an electrical drain. I have already replaced the battery two times and the car has less than 15,000 miles. Apparently this is the same problem as in the 2016 - 2019 class action suit.

The battery died after 2 years and 15000 miles. I was with my whole family ( 2 months old, 2 and 4 years old) away from home. I was able to reach the dealership leaving my family in a store and they said that nothing was wrong with the battery. Next day the car wouldn’t start and they finally replaced the battery under my extended warranty. Today I discover that there is a class action settlement for older models of my car. I was advised to write a complain to you. Apparently they didn’t fix the problem with newer models either.

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

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.

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.

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.

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.

Car has always refused to accelerate if gas pedal is pushed down too quickly. Just before 60K miles, on way home we had pulled over at a roadside stop on a hill. Tried to pull across highway to continue up road, car refused to accelerate and luckily were able to brake in time to keep from getting t-boned by big truck heading down the hill. No trouble lights came on, so weren't sure if this was operator failure from pushing gas down on hill or mechanical problem. Also were too close to 60K miles to get home and back to dealership without going over warranty and serious service issues with dealership previously, and leaving for vacation following day. Decided to see if there were further problems. Live at 8K elevation, vacation at half that. No further problems until after returning from va

When operating the 2021 Ascent, I experience intermittent problems at various shift-points in the CVT and at various RPMs. The transmission seems to shudder and slip between shift-points, and the shuddering sensation is so severe that it transfers up through the steering column and the steering wheel shakes. I have brought the vehicle to my dealership (Kocourek Subaru in Wausau), and they have acknowledged that the shuddering is taking place and even documented it in the 18K service invoice. They ran it through the protocols for NHTSA TSB 10185089, and were not able to achieve fluctuation in the gear ratio. Since the TSB test, the dealership again took the vehicle and has had it for ca. three-weeks, and have tested it, replicated the issues described above, downloaded data, sent data

At 1 month old with 1,661 miles - the driver's side window started showing a cracked line that began to grow throughout the course of driving on a Saturday afternoon.

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.

The contact owns a 2021 Subaru Ascent. The contact stated that after the vehicle was parked in the garage, the contact returned to the vehicle and noticed a crack on the windshield. The crack was on the lower driver’s side of the windshield and moving upward. There was no impact to the windshield to cause the fracture. The vehicle was taken to the dealer but was not yet diagnosed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 3,141.

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.

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!

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 w
