2020 Subaru Ascent Complaints

The Transmission is slipping on my 2020 Ascent. I had the recall wrk-21 performed in July of 2025. Over the last 6 months the car has been hesitant to go at low speeds and shakes at high speeds. Over the last month the transmission started to slip while accelerating , especially up hill. There would be a grinding noise and RPMs would jump. I took it to the dealer and they confirmed it was the transmission via camera test. I called Subaru of America for goodwill help with the cost knowing that there is a know issue with the transmission. They refused due to the mileage, 121,010. •What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission is slipping •How was your safety or the safety of others put at risk? The car is hesitant to go from a starting position. The car will jerk back and forth when trying accelerate when merging or crossing a road. I am also very concerned of catastrophic failure at high speeds. •Has the prob...

My strut bearings have been replaced several times in the drivers sides, my shock and strut has been replaced twice on the drivers side and now the passenger side is doing the same thing. The dealership tells me that there is nothing wrong but research shows this car has known suspension issues. My passenger side front has a loud metallic grinding sound when turning the wheel in park. I’m told this is the brakes which makes no sense. The car feels like it is on ice or sailing down the road, and the car does not maintain an alignment causing the insides of tires to wear out after 15,000-20,000 miles and need to be replaced.

I am reporting a repeat safety concern involving a 2020 Subaru Ascent. The vehicle was involved in two separate collisions after failing to decelerate as expected following normal brake pedal application. The first incident occurred on January 26, 2026. While approaching a traffic signal, I applied the brakes under normal driving conditions. The vehicle did not slow as expected and struck the rear of another vehicle. Property damage occurred, but no injuries were reported. The second incident occurred on May 5, 2026. While approaching a stop sign at approximately 35 mph, I again applied the brakes under normal driving conditions. The vehicle did not decelerate as expected and entered the intersection, colliding with a vehicle traveling perpendicular to my direction of travel. Both vehicles were towed. No injuries were reported. During both incidents, there were no forward collision warnings, automatic emergency braking interventions, or other alerts observed prior to impact. Following...

I am submitting this complaint regarding a known exhaust manifold/flex pipe failure affecting my 2020 Subaru Ascent Touring (VIN: [XXX] ). My vehicle was diagnosed by a Subaru dealership with a “broken flex pipe on the header” causing excessive exhaust noise and exhaust leak concerns. Repair estimate was slightly over $2,000. After researching the issue, I discovered numerous reports from other Subaru Ascent owners describing identical failures involving cracked exhaust manifold welds and failed flex pipe sections. Subaru has also issued TSB 09-106-23 involving exhaust manifold weld cracking and redesigned replacement components for this issue. Symptoms began in the low 70,000-mile range and progressively worsened before formal diagnosis at approximately 83,000 miles. This appears to be a widespread defect involving emissions/exhaust components. Many owners online report loud cold-start exhaust noise, cracked manifold welds, failed flex pipe sections, exhaust fumes/smells, and expe...

The pressure sensor coming out of the transmission has failed, and it's pushed transmission fluid throughout the engine harness, transmission harness, the bull harness in the dash and the 02 sensors. All of those have been damaged. The car is now unsafe to drive due to the pressure sensor failing. This information comes directly from the Subaru dealership. There was nothing prior to this that indicated there was a problem. I bought the car from a certified dealership 8 months ago and it was a certified pre owned vehicle.
