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 contact owns a 2023 Subaru Ascent equipped with Falken Tires, Tire Line: ZIEX, Tire Size: 245/50/R20, DOT Number: 1R8KH DM2R 0323. While the contact's wife was driving at an undisclosed speed, there was rubber flying from the vehicle. The vehicle was driving to the shoulder of the road, and the driver became aware that the rear passenger's tire sidewalls were shredding, and the tread was separating. The contact's grandchildren were inside the vehicle during the failure. AAA Roadside Assistance was contacted. Roadside Assistance replaced the tire with the spare tire. The vehicle was driven to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced NHTSA Campaign Number: 23V258000 (Tires); as a possible cause for the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 25,000.

I am reporting two issues with my vehicle that I believe require further attention and repair assistance. I am requesting that both issues be properly repaired without any charges to me. There are no warning lights, error messages, or other dashboard warnings related to either issue. However, both conditions are abnormal and affecting the vehicle’s operation and ownership experience. 1. Steering Noise (Inside Cabin). The steering assembly inside the cabin. Whenever I make any type of turn, either left or right, I hear a noticeable clicking/clocking noise coming from inside the steering column area. I want to clarify that this noise is not coming from the wheels, tires, suspension, or steering components connected outside the cabin. The sound is specifically coming from the steering wheel/steering column area inside the vehicle. I have had this concern checked, and the only suggestion provided was to replace the suspected component. The dealer did not provide written confirmation of the diagnosis but verbally advised that they could replace the component and see if it resolves the issue. However, since there is no guarantee that the replacement will correct the problem, I do not feel comfortable spending my own money on a repair that has not been confirmed. I have also spoken with multiple third-party mechanics, and some have verbally indicated that this type of steering noise is a known issue that can occur after a few years and may be related to the clock spring (spiral cable/ribbon) or another internal steering column component. Because this appears to be a known manufacturer-related concern and not a result of misuse or neglect, I request that the issue be properly repaired at no cost. 2. Rear Brake Squeaking Noise. The rear brake pads and rotors are new, but the brakes continue to make a noticeable squeaking/squealing noise. The noise usually occurs after driving for some time, especially in warm weather when the brakes reach normal operating temperature.

The vehicle exhibited transmission slippage but did not provide any warning lights or other symptoms . About 100 miles later, the Automatic Transmission Oil light came on (flashing YELLOW), and all other systems light up (both Yellow and Red) disabling front collision, auto vehicle hold, RAB, etc. Pulled to a safe location and left in park for 10-15 minutes per guidance. Had towed to dealer to determine issue, transmission failure on a 3.5 yr old vehicle with 80,019 miles.

Sirius XM ads showing up and there’s no way to opt out. The ads are distracting/difficult to close and cover a good amount off my media system even while driving.

2023 Subaru Ascent, under manufacturer basic warranty. Factory OEM battery has repeatedly failed. Voltage drops below 11.5V in normal use. Three documented failures in six weeks. SAFETY INCIDENT: Vehicle died on a public street and became completely immobilized. Brake warning light activated. Vehicle would not move even after a jump start. Passengers had to exit in a live traffic lane. A second vehicle was used to transport a replacement battery. The original battery is in my possession and available for inspection. A subsequent failure occurred when the original battery was reinstalled for a manufacturer-required diagnostic. Vehicle again would not start. KNOWN DEFECT: Subaru TSB 07-213-22R (revised 03/28/24) covers the 2023-24 Ascent battery and acknowledges the factory specification as inadequate, directing dealers to replace the battery, tray, cover, and holding rod with higher-capacity parts. This TSB was not proactively applied to my vehicle. The dealer did not identify or disclose it at earlier service visits where the battery concern was reported and "could not be reproduced." No recall or proactive owner notification has been issued. Dealers are not applying the TSB preventively. A complaint is open with Subaru of America Customer Advocacy. The manufacturer has declined to reimburse the out-of-pocket emergency replacement and has required a dealer diagnostic that has been repeatedly blocked by manufacturer/dealer procedural requirements.
