2022 Subaru Ascent Complaints

ENGINE — Filed 05/10/2026

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.

STEERING,POWER TRAIN,ENGINE — Filed 04/21/2026

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.

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.

SEATS — Filed 12/02/2024

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 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.

POWER TRAIN — Filed 09/09/2025

Traveling back home from our vehicle downhill the vehicle started aggressively started to downshift that caused disengaging it was scary and almost wrecked into a tree.

AIR BAGS — Filed 03/18/2026

While driving under normal road conditions at approximately 35mph, the side airbags in the vehicle deployed unexpectedly without any collision, impact, or apparent external cause. There were no warning lights, alerts, or prior indications of any system malfunction before the deployment. The sudden airbag deployment startled the driver and created an immediate safety risk, including potential loss of vehicle control and risk of injury to occupants. The vehicle had not struck anything, and there were no road hazards or events that would reasonably trigger airbag deployment. The vehicle has since been inspected by insurance representatives and a dealership, and repair estimates have been completed. At this time, the cause of the deployment remains UNKNOWN. This incident raises serious concerns about a potential defect in the airbag system or related sensors, as the airbags deployed without a triggering event.

UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE — Filed 02/20/2026

2022 Subaru Ascent. Noticed progressive strong odor in the car. After rain had significant fluid accumulation in the front passenger ceiling, inside front passenger door (sloshing), and wet carpets on the floor on the passenger side. Serviced by Subaru dealer water specialist who reported (1) clogged moonroof drains and "popped off connector" leading to flooding of the entire front passenger ceiling; (2) detached vapor barrier in the passenger door allowing water to collect inside the door and drain into the car; (3) significant concern for mold based on the extent of damage and odor accumulating over time. Told by dealer the drains could be unclogged and they'd repair the popped off connection with a zip-tie fastener since it was not tight enough before, re-affix the vapor barrier in the door, but otherwise their expressed SAFETY concern related to the extent of suspected mold and the poor effects that would have on the health of us and our children. Told the mold was unlikely to fully remediate despite usual efforts, as it creates a fibrous web that is very difficult to ever fix, and the recommendation was that we probably not drive the car again. Told no water damage of any etiology is covered under any Subaru warranty. Dealer refused at first to give documentation about the service or recommendations. Later gave but left off mold documentation - we requested they add it back on, if we choose to sell or trade in the vehicle later we refuse to do so without the mold and associated health risks being public knowledge for a future owner of this vehicle. We also reported that our Subaru Eyesight (collision avoidance system) had been intermittently shorting out, online reports show this can be related to drain floods. No report/update thus far by Subaru on this, also not included in report. We filed a complaint with Subaru of America but have not been called back despite two weeks of repeated calls to them for an update.
