Once or twice a day my vehicle hesitates from a light and I have to almost floor it to get it going again.I have brought it to 2 different Subaru dealers 3 times and they say they can't fix the problem.
2021 Subaru Forester transmission complaints
Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
Thermo control valve failed at about 42000 miles on 2021 Subaru Forester Premium, on 1/1/24. Owned 3 yrs 1 mo. Car was parked at work. Immediately after car was started up for return commute -- check engine light was on, ADAS systems ("Eyesight") disabled, blue low coolant temperature light on, and no heat through HVAC. Fortunately car driveable, despite safety being compromised with disabling of the safety features (blind spot monitor, rear cross traffic alert) and concern about damaging engine being forced to drive home with check engine light on. Engine failed to warm despite 40+ min highway trip. As this was commute vehicle, forced to take next day off work to have check engine light looked at. The next morning windshield ice had to be manually scraped (no heat). Drove car gingerly to dealership ( $1000 to replace). Furthermore, if TCV fails whilst driving (as could have happened, and has been reported by others elsewhere), this will be a safety hazard with sudden disabling of blind spot monitor / rear cross traffic alert.

The contact owns a 2021 Subaru Forester. The contact stated while depressing the brake pedal and attempting to park in the driveway, the vehicle excessively independently accelerated in speed. The brake pedal failed to stop the vehicle and the vehicle was shifted into Park in order to come to a stop. The vehicle caused damage to the door and garage. There were no injuries reported. The vehicle was not diagnosed. The dealer was contacted, and they stated they were not aware of any recalls or complaints for the failure. The manufacturer was not contacted. The failure mileage was 10,000.
Car was parked on driveway (6 degree slope to rear) Car was placed in park Driver exited car to go into house when she came out car had rolled down the driveway to hit another car parked across street rear facing bot cars had rear damage. The same thing happened to the car one week later when parked in the garage placed in park but started to roll back. Was able to stop it because I was still in the car I use the parking brake now all the time
On 04/02/2022, several minutes after having filled the gas tank, I was driving at about 35 mph on a two lane road at constant throttle, when the engine suddenly lost power for several seconds before it regained acceleration. There was a pickup truck following me very closely and it swerved around me to avoid hitting me. On 04/13/2022 , several minutes after leaving my driveway, at about 27 mph on a two lane road, the engine again lost power for several seconds before resuming power. In the first case the engine was at operating temp., in the second case it was cold. I will take the vehicle to the Subaru dealer from whom I purchased it in a couple of days to evaluate the problem, which I consider to be serious. In both cases I was so surprised that I didn't look at the tach etc. 12,500 miles.
The vehicle gets a shudder at different speeds and it feels like it's either the transmission is slipping or its coming from the motor but it NEVER THROWS a Trouble Code so as the dealership says if its not throwing a trouble code they can't diagnose it until it does. So that's why I don't like these vehicles because no one know how to fix it old school by being a real mechanic and going old school to find the issue.
