Electrical system
160 reports4 fires1 related recall
“All the safety systems become disabled and check Engine light goes on because transmission fluid is being pumped Out of a faulty secondary pressure sensor part 31878aa020,( defective and replaced with 31878aa021), into the engines wiring at the car computer, transmission computer, and bulkhead connector in fuse box causing all sorts of engine codes. The setting of the engine code closes all the vehicles driver safety systems and changes the dynamic of the drivers driving experience. As the problem gets worse, it can render the car powerless on roads and highways making operation dangerous. I have my car parked in front of the house with the battery and electrical connectors unplugged. This problem is covered by one or more recalls and safety campaigns, but subaru refuses to fix mine and other peoples that I found on Facebook. Someone online listed a $6500.00 repair estimate. They just had it repossessed instead. This part causes the pressure differences that cause the jerky ride and is specifically alluded to in the recall, plus subaru even changed the part because it was defective.”
Power train
90 reports2 crashes3 related recalls
“The contact owns a 2019 Subaru Ascent. The contact stated that while driving at 50 MPH, the vehicle hesitated. The vehicle was taken to a local dealer, where diagnostic trouble codes were identified, and a vehicle reprogramming was performed. While driving, the failure recurred. The vehicle was taken back to the dealer, where it was diagnosed that the transmission had failed and required replacement. Warranty coverage was not available; however, a loaner vehicle was provided. The contact associated the failure with NHTSA Campaign Number: 21V955000 (Power Train). The manufacturer advocacy center was notified. The failure mileage was approximately 108,000.”
Visibility/wiper
66 reports
“Subaru windshild in my 2019 Ascent have been replaced twice in 30,000 miles due to very inadequate glass. I'm struggling to get Subaru to acknowledge their responsibility to replace this current cracked windshield with a new part, as per my reading of a settlement that they should be following [XXX] ). They are currently trying to send me to a 3rd party repair business to do the repair, but supposedly they have fixed the part on more recent versions of the car. By comparison, I had a Toyota Highlander for 11 years and never once had to replace the windshield glass. Yes, it took a beating, but never once cracked like this glass does. It's not up to the task, and clearly dangerous.”

“The contact owns a 2019 Subaru Ascent. The contact stated that while his wife was driving at approximately 75 MPH, a deer ran across the highway and hit the left driver's side of the vehicle. The air bags did not deploy upon impact. A grayish smoke began to emit from the vehicle as the contact's wife immediately pulled off to the side of the road. Due to the damaged cause by the impact of the deer, the contact's wife had difficulty exiting the vehicle. The contact's wife used excessive force to open a crack in the door, which was enough to slide herself out of the vehicle. The vehicle became engulfed in flames soon after exiting the vehicle, and the authorities were called to the scene. The fire department arrived at the scene and managed to extinguish the fire. The contact's wife sustained bruising to her left shoulder, left leg, and left arm but did not seek medical attention. A police report was filed. The vehicle was initially towed to an independent tow yard and was later towed to an insurance holding facility. The contact stated that the vehicle was destroyed as a result of the fire, but the insurance adjuster had yet to determine a final ruling on the…”
Service brakes

“Replaced rear brakes and rotors in August 2025. By may 2026 they had worn down to the metal and needed replaced again. Only had 13000 miles on them. After multiple diagnostics testing was done, no issues were found with the brake system. Monitoring new pads and rotors. Still wearing rapidly but even. After only 6 weeks, they have reached about half of their life.”

“Over the course of 5 years, a lot has been mechanically wrong with our vehicle. Each service appointment yielded a 'cannot duplicate' response. Recently, my car has been in the service department a few times. My car had recall work performed on a ground bolt, and my husband advised them that the car had a 'rich fuel' smell when starting with the hood open. I've complained since 2021 of a smell when pulling up the mountain. The smell is what I described as a perm solution smell. Each time, the response was 'cannot duplicate.' In February, I took the car in to have the exhaust inspected because it was getting louder each passing day. I was advised that the entire exhaust needed to be replaced, and I would be responsible for costs. I brought my car home, unrepaired, and called Subaru of America to file a claim through them. I had repeatedly expressed concerns, and nothing was done, yet I'm expected to foot the bill now. Since February 12th, I have been back and forth with Subaru and just made the appointment to get the exhaust work completed, with a small contribution from Subaru. However, this past Saturday, [XXX] my vehicle caught on fire while driving. I am…”
