Our thermo control valve (TCV) assembly failed and caused dangerous loss of speed and control while on the highway. Subaru is fully aware of the defect in their design as they issued a service bulletin to inform their service centers of a new, fixed TCV assembly that is retaining the same part number (a notice only sent to their service centers, NOT to owners). Please see attached. Despite being aware of the defect, Subaru has not voluntarily replaced the defective TCV assemblies or even bothered to notify owners. Instead, they are letting us put our families and other drivers in dangerous situations through sudden loss of control. There are pages and pages of other owners experiencing this dangerous issue and - like me - being surprised to find it's a known issue that Subaru is not proactively fixing (see any of the owner forums like subaruforester.org).
2020 Subaru Forester acceleration complaints
Page 2 of 2: complaints 11 to 24 of 24, newest first, as owners wrote them.
While merging into a lane, I went to accelerate. I pressed the accelerator pedal to the floor to quickly get up to the speed of traffic. After successfully merging into the lane, I took my foot off of the accelerator pedal and noticed that my vehicle was still accelerating. The floor mat was not interfering with the accelerator pedal. Thankfully, slamming on my brakes while in the middle of a lane caused the accelerator pedal to come off the floor and my vehicle began to decelerate. This was frightening and an absolute hazard to the well-being of myself and other drivers and pedestrians on the road. Without quick thinking and a lack of traffic ahead of me, I and others would have likely been involved in a life-threatening traffic accident. Whether this is a reoccurring incident or a one-time incident, this is not acceptable for any vehicle sold and allowed to be driven by a manufacturer or dealership.

I drive this V little, but the steering wheel has repeatedly tried to jerk me into the left lane when tuning right and right when turning left! I stopped using cruise, but it still does it. I am an advanced driver, but don't low, if I could overcome this if it acted like some other 2020 Foresters I've read owners state have gone off the road and rolled over! Also the auto stop - start often shuts engine off when power is needed - is totally unpredictable! This is my wife's car, but she got it as the seat works with my V bad back! Had I known the Eyesight system would malfunction (I did not trust it, but hoped it would be ok!), I'd have insisted on getting a good older car without unproven so called driver aids! We really don't have the $ to replace the car!

The car was parked and idling for a few minutes as a passenger exited the vehicle. While parked, the car began to shake slightly, it was then placed in reverse to get out of the parking space. Still shaking. When it was put in gear to go forward, the car began to accelerate on its own. The driver was able to use the brake to stop the vehicle but, when she took her foot off the brake to make a left turn and towards the park exit, the vehicle accelerated abruptly, and the car surged towards a main road. The passenger in the seat next to her was able to see clearly that the driver’s foot was not on the gas pedal. The driver was able to steer the vehicle clear of the park visitors, avoid other vehicles in the parking lot, and stop the car prior to reaching the traffic light at the main road. Stunned by the incident, the driver decided to return the vehicle to the parking lot, so she opted to make a U-turn at the light. As she turned the vehicle, the vehicle accelerated once again without her foot on the gas pedal. After the driver was able to maneuver the car into a parking space, the vehicle started to shake violently, and the driver shut off the engine. When the driver attempted to restart the car with the intent to drive home slowly, the driver placed the vehicle in reverse, and applied her foot to the gas pedal but, the vehicle would barely move. The engine revved when the pedal was pushed all the way to the floorboard but, the vehicle only moved at approximately 5MPH. Once parked in a space, the vehicle shook violently, and the dashboard lights lit up. The vehicle was turned off and emergency call button inside the vehicle was used to contact Subaru. The car was towed to the dealership.
