There are 10 owner-reported speed control & cruise complaints for the 2020 Subaru Foresterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Eyesight pre-collision braking feature and pre-collision throttle management feature malfunctioned and caused the 2020 Forester to accelerate unexpectedly and lurch forward while I was manually braking and slowing to come to a complete stop behind two other vehicles stopped at a steady red light. See class action lawsuit Weston, et al. v. Subaru of America, Inc., et al. In US District Court Case No. [XXX] which alleges that the vehicle contains certain defects that caused sudden and unintended acceleration without driver input; acceleration while manually braking; and that these defects created a safety risk, because they severely affected the driver's ability to control the car's speed, acceleration, and deceleration, and increase the risk of a collision, which did in fact occur. The defective car was completely totaled and towed to a salvage yard by the police and the insurance company. Defect malfunction caused a collision which resulted in property damage and personal injury to three vehicles and three people. I mentioned the defect to my insurance company at the time of the accident. I do not know if they chose to follow up and inspect the vehicle. The problem occurred twice before ( not resulting in property damage or injury) and I took it to my Subaru dealer both times and they claim that they could not find anything wrong, but oddly did not note that they checked for the problem which I brought to their attention on the written summary/invoice for my service visit. See the class action lawsuit- this is apparently the typical dealer non-response to the problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving, most of the dash errors lights lit up- alerting me that the Eyesight Warning, RAB ( Reverse Auto Braking) and other safety functions were disabled. The Check Engine light was on and a flashing S next to it. Cold Engine light was illuminated as well. Dealer diagnosed with a faulty Thermal Control Valve, which somehow disabled all safety features. This is a common failure of Subarus and a recall is needed.
Unintentional acceleration. After making right turn, vehicle accelerated for approx 1/2 mile until crashing into wall. Several attempts at braking and trying to shift into neutral did nothing.
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.

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.
