2020 Subaru Ascent UNKNOWN OR OTHER

i purchased this vehicle from Northwest Chevrolet in McKenna, Wa on [XXX] and they did not disclose to me that there were open recalls prior to my purchase. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Although the NHTSA form does not include a transmission category, this complaint concerns a critical transmission-related defect in my 2020 Subaru Ascent, which caused oil migration into the wiring harness and contamination of the Engine Control Module (ECM). This complaint concerns a critical transmission-related defect in my 2020 Subaru Ascent. The vehicle has been inoperable since June 2025 due to a failure of the transmission secondary pressure sensor. This failure caused oil to migrate into the wiring harness and ultimately contaminated the Engine Control Module (ECM), rendering the vehicle undrivable. Authorized Subaru dealership Huberger Subaru in Colorado Springs documented the following: - Replacement of the transmission secondary pressure sensor - Replacement of the engine wiring harness - Check engine light returned after repair - Confirmed oil contamination of the ECM Despite repeated repairs and part replacements, the vehicle remains out of service for over seven months, with no confirmed timeline for resolution. Subaru of America has not provided meaningful updates or a clear repair plan, and corporate representatives have failed to respond to emails and phone calls. The extended downtime and lack of repair constitute a safety concern, as the vehicle could fail while in use under certain conditions. Additionally, $400 was improperly withdrawn from my account in July 2025 for rental reimbursement during the warranty repair period and has not been refunded. I am seeking prompt resolution, including repair or replacement of the vehicle, reimbursement for the rental charge, and any appropriate actions from Subaru to address this safety-related defect.

Vehicle: 2020 Subaru Ascent Issue: Cold weather software glitch If you are operating an Ascent or possibly other Subarus with the CVT in temperatures below -20F be certain to have either a small wrench or the appropriate size socket to loosen the ground clamp on the battery ground cable with you so you can employ what I call the magic Windows fix wherin one completely de-powers the system and reboots it. With all the ridiculous interconnections, if the CVT temperature sensor thinks the tranny is too cold the cars operating system looses it mind and goes completely bonkers. Subaru obviously did no cold weather testing. We have had 2 failures in cold weather. It only happens at temperatures well below the-20F range. The first case happened last year while driving after being stopped for a couple of hours. Everything seemed normal and then suddenly several warning lights came on and all of the safety systems and the eyesight system shut down. The car ran and drove, but none of the associated systems would work. No traction control. No cruise control. Several other systems. The only solution was to disconnect the battery and get this rolling computer to reboot. This was a temporary fix as the condition repeated itself although the car was driveable but with none of the safety systems operational. This year we were out in cold weather, -25 to -32. We went to a place to have lunch and when I went to restart the car the app failed to do so. So I put on all my gear and went out to start it manually. It would not start and all the warning lights were on and the radiator fan was running full tilt at -25F with the car off. I tried twice to get it going by pulling the battery cable to get it to reboot. Evidently when this happens you must leave the battery disconnected long enough (about 5 minutes) for all the capacitors in the electronics to drain. Once restarted, the car drove normally but we did not shut it down for any reason for the rest of the day.

Lug nut studs fail frequently. Have replaced 3. An additional failure identified today during routine tire rotation. Safety issue as wheel can separate from vehicle while driving.

Driver side window malfunctions intermittently. When raining, slow to go down or up, also skips as it goes up and down.

There is a significant crack in the inside rear panel of my panoramic sunroof, and no apparent or visible point of impact. The crack is spreading and needs to be replaced or I fear the glass will shatter. There is no evidence of the crack on the exterior, only on the interior. Car is out of warranty but only has 23K miles and is 4 years old. Took the car to the dealership, and they wanted to charge $4000 to fix. Contacted Subaru of America and they refused to fix. Have been on many Ascent/Subaru forums online and it appears there are multiple complaints about these cracks.

Unknown

The driver door window gasket cracked and is hanging loose inside the door, letting air to get air while the vehicle is in operation. I would expect this after 10 years of use, but the vehicle is about 3 years old.

The hood shakes alot. I've taken it in a couple of times. They say it's in the design. I fear that the hood is going to come up some day and cause an accident. It lifts and shakes to the side. Even a passenger noticed it and was scared after seeing it. I'm stuck with the car, but am afraid when on the road. I bought it brand new. Have had it almost 4byears. Only have 27,000 miles on it. I'm afraid to drive it!

Drive chain could compromised but there is lack of parts to fix issue which could prove costly to the transmission. Need to know what I can do to fix before it becomes a problem.

The windshield is fragile- there have been 2 broken windshields in the last 3 months- one from a minor ding and one that is not confirmed as to why the crack started (dealer says a ding- we did not hear or see a ding prior to the crack popping into place as we were driving). In both cases the cracks extended to over 50% of the windshield rapidly and suddenly while driving. The sudden nature and force/sound of the cracking causes distracted driving and creates panic in the car. Both windshields have been replace so inspection is not available. The problem has been reported to the dealer and replaced by the dealer. There were no symptoms or warning of the cracks- I have never seen windshields be destroyed so easily.

The car drains the battery prematurely overnight

2020 Subaru Ascent that I purchased in November of 2019 had original brand new battery replaced in July of 2020 The “ new battery “ is now defective and car needs to be jump started. Defective battery or defective electrical system?

Battery life issue

The windshield spontaneously cracked, for no apparent reason. It was not hit by anything. The car was sitting still and the windshield just cracked. I have babied this car. It only has 15,000 miles on it, kept in a garage, no ice or snow build up, rarely driven in bad weather.

Front windshield cracked for no reason

It has been six months and I have not received any communication from Subaru since the recall was announced. Submitting a complaint that the known recall has not been addressed in a timely manner.

First, we received the recall letter after the allowed deadline. We were told that the recall would be fixed by May from Subaru. The recall says it can cause an increase risk of a crash. We bought this car primarily due to their high safety rating as a way to transport our new born child. She is now two. We have minimized and avoided taking long trips on the car. But with summer coming up and no fix in place, I think this justifies "unable to repair in a reasonable amount of time". Currently I am fighting to get an alternate source of transportation. They initially agree to pay $50 for a rental. But with rental prices that only covered half. They do not offer a loaner. I am getting bounced back and forth between Ascent dealer and the subaru corporation. As of now, nothing has been done. We have a trip scheduled in a few weeks. We don't feel safe using this vehicle. What can be done to remediate this?

My car did not start and the anti-theft light came on the dashboard (the one with the car and lock symbol). I know battery issues have been a known problem with my subaru model and i bought the car in oct 2019 so it's been less than 3 years. The battery should not be dying this quickly. I had to get a jump start to get the car on. After a few hours, i tried starting it again and it did not work. I was told I'd need to get my battery replaced.

My vehicle windshield made a popping noise and a crack appeared on the front window, which was about 4 inches long, but the crack continues to grow as the vehicle is driven. The crack appeared on Dec 30 2021

My Driver’s side window cracked while sitting in driveway after 7ish pm Saturday night, June 5th, 2021. My car was sitting outside from roughly 6:30 pm to 7:15 pm with windows down and then I put up the windows as I was going to move into the garage. I got out of the car and was side tracked with neighbors for approximately a half hour. I went to move the car into the garage about 7:45 pm and my window was cracked about a foot. It has since spread the length of the window. (see picture attached) I called Subaru as a window should not do this. A Resolution Specialist is suppose to call me back, but who knows when that will happen. I need to get it fixed as it is not safe and I don’t want it to shatter into my lap.

2020 SUBARU ASCENT WITH APPROXIMATELY 6,700 MILEAGE. WINDSHIELD CRACKED FOR NO APPARENT REASON WHILE PARKED IN OUTDOOR PARKING LOT. IMMEDIATELY HEARD NOISE AFTER WE GOT IN CAR AND SAW THE CRACK. STARTED MIDWAY AT TOP OF PASSENGER SIDE OF WINDSHIELD AND PROCEEDED DOWN AND ACROSS 23 1/2 INCHES. NEAR TOP OF CRACK THERE APPEARED TO BE A CHIP SMALLER THAN A SMALL PEA OR PEARL. CRACK HAPPENED FOR NO APPARENT REASON.

WITHIN A FEW MONTHS OF DRIVING THE CAR OFF THE LOT THE WINDSHIELD CRACKED FOR NO APPARENT REASON UNDER NORMAL DRIVING CONDITIONS. WHEN THE CRACK FIRST APPEARED IT WAS STATIONARY.

I drove the vehicle Tuesday October 26th 2021 and the radio was on, but no sound coming from speakers. I found this odd as no changes were made to settings and dismissed this as something I would take a look at when home and not driving. The car was parked and turned off in the garage from Tuesday October 26th until Friday October 29th 2021. My husband went to run errands Friday October 29th and the car was dead- couldn't get the battery to charge with jumper cables or even put the car in neutral to have it towed. We called a tow truck Saturday morning October 30 2021 and the tow driver jumped the car to start- it started up fairly quick and was able to attach to the truck to be towed to Byers Subaru in Columbus Ohio. The technician told me the battery died as a result of leaving the keys in the car when it was not being used. I asked why the stereo speakers appeared not to work and I was told that was likely an update issue and unrelated to the battery being dead. I asked that they take a second look at the car and keep another day till Tuesday November 2nd 2021 so they did and then texted me there are no issues with the car and refused to replace the battery or address the stereo issue.

WHEN I PARKED MY CAR 3 DAYS AGO, MY WINDSHIELD WAS PERFECTLY FINE. SINCE PARKING IT THE CAR HAS NOT BEEN DRIVEN. TONIGHT WHEN I GOT IN THE CAR TO DRIVE TO THE STORE I NOTICED A CRACK IN THE LOWER PASSENGER SIDE OF THE WINDOW THAT WAS ABSOLUTELY NOT THERE WHEN I PARKED THE CAR 3 DAYS AGO. THE CRACK IS LARGE AND VERY OBVIOUS, AND IT'S SOMETHING I CERTAINLY WOULD HAVE NOTICED. THIS WINDSHIELD HAS CRACKED FOR ABSOLUTELY NO REASON. THE CAR HAS BEEN GARAGED THIS ENTIRE TIME AND THE WEATHER MILD.
