Subaru Ascent Reliability by YearBest & worst years, problems & recalls — NHTSA data

While driving the passenger door window behind the driver burst, then began falling into the car. The safety issue would have occurred if one of my grandchildren were sitting there. Also, the startling event of it just bursting and possible causing a jerk in the car. The dealer said that they have not heard of this and would not repair under warranty (brand new car, purchased in September). Police investigated and saw nothing that would have caused an outside force to break the window. No warnings

I own a 2025 Subaru Ascent Limited. At approximately 20,000 miles, one of the original tires (factory-installed) developed a straight split along the tread/shoulder area. The cut was very straight, almost like along a seam, and I could see metal/steel cords exposed through the opening. There was no major impact, curb strike, or pothole event that I’m aware of, and there was no obvious sidewall or wheel damage. The Subaru dealer inspected the tire and replaced it, but I do not have the tire in my possession, so I no longer have the exact tire brand/model or DOT number. I have photos of the damage and a repair order from the dealer showing the tire replacement. I have also reported this incident to Subaru’s customer advocate department because I am concerned this may be a safety-related tire or manufacturing issue on a relatively new vehicle with low mileage.

The driver side rearview mirror shakes and vibrates under normal driving conditions. This is distracting and nauseating to the driver. This is a safety issue because this mirror is used for checking for vehicles before changing lanes.

Driver side mirror vibrates making the view in the mirror blurry. The distorted picture causes confusion and safety hazard as it's very difficult to see in day and almost impossible at night. Vibrations are noticeable in the driver's side B pillar. According to the dealership, this is related to the car's frame, no further details were provided so far. Car has been in the service for almost two weeks due to this issue.

The drivers side mirror glass shakes while driving. Visibility in the mirror is extremely limited making it impossible to see vehicle approaching or to judge distance. After dark the mirror is useless.

No particular incident happened, but the driver's side view mirror vibrates when moving especially at high speeds and/or bumpy roads. Worse at night as when you look, headlights in rear are shaking and make me dizzy and not look. The passengers side is nice and stable. Doesn't vibrate and shake.

The driver side mirror is unusable. The mirror it self shakes so much while driving you cannot see anything clearly or safely.

The front exhaust pipe on my 2022 Subaru Ascent cracked at approximately 77,800 miles. The component is available for inspection. Prior to diagnosis, I noticed a rattle/fluttering noise coming from the undercarriage during acceleration. The problem was confirmed by an authorized Subaru dealership. Subaru has issued TSB 09-106-23 acknowledging this is a known design defect affecting 2019-2023 Ascents, and has redesigned the part to correct the issue. Despite being within the 8 year/80,000 mile federal emissions warranty period, the dealership denied warranty coverage, claiming coverage only applies in California and Maryland. This is incorrect - the federal emissions warranty applies nationwide. The dealership quoted over $1,000 out of pocket for a known manufacturing defect on a 4 year old vehicle. The cracked exhaust pipe poses a safety risk as exhaust fumes can enter the vehicle cabin. I am requesting NHTSA to investigate whether Subaru is improperly denying federal emissions warranty claims on affected vehicles outside of California and Maryland.

The contact owns a 2022 Subaru Ascent. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle experienced a loss of power steering assist, the speedometer was inoperable, and the transmission failed to shift into gear. The vehicle was taken to an independent mechanic, who inspected the brakes and reset the check engine warning light, but the failure persisted. The vehicle was then taken to the dealer, who determined that the rear radar sensor module beneath the rear bumper had corrosion from car wash or road salt. The dealer replaced the rear radar sensor module and sealed it with silicone. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 60,000.

Exhaust "Nut" mysteriously went missing, causing noises, and Subaru technician stated to replace exhaust if issues persist. Vehicle was under warranty, only been serviced by certified Subaru technicians, and multi-point inspections were allegedly performed during every service, however, the exhaust "nut" were somehow still went missing.

The front driver seat cushion/seat cover is deteriorating and ripping at the front portion of the seat. While driving, I can feel road vibration and impacts through the driver seat much more than normal, and the seat no longer feels properly cushioned or supported. I am concerned this affects the driver seating position, comfort, and ability to maintain proper control, and it creates a distraction while driving. The failed component is the front driver seat cushion/seat cover and it is available for inspection upon request. I have seen Subaru Service Bulletin 12-273-19 for earlier Ascent model years describing redesigned front seat cushion trim covers due to early wrinkling/durability concerns, and my vehicle appears to have a similar front seat cushion/cover failure. The problem has not yet been confirmed by a dealer or independent service center. The vehicle/component has not yet been inspected by the manufacturer, police, insurance, or others. There were no warning lamps or messages before the problem appeared. The first symptoms were increased road feel through the driver seat and visible deterioration/ripping of the seat cushion/cover. Cause is UNKNOWN.

The contact owns a 2022 Subaru Ascent. The contact stated that while operating the vehicle, there was a whining sound coming from the transmission, and the vehicle failed to properly accelerate. The vehicle was slowly driven to the local mechanic, who diagnosed the vehicle and determined that the transmission had failed and needed to be replaced. The transmission was replaced, and the vehicle was repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 115,000. The VIN was not available.

My eyesight camera keeps failing, it just started like a week ago I had it scanned and it is saying there is an error with the eyesight camera, I have not had an issue with it until now.
