2020 Subaru Forester

Subaru of America is aware of the problem which impacts several models and model years, see Subaru Service Bulletin 16-132-20R. Transmission slippage and bounce feel during acceleration. Can be strong enough at times to visually see occupants moving with momentum/bounce at times. Could contribute to vehicle not maintaining/reducing/responding to speed control systems, failure of transmission components, stranding occupants, and other similar hazards that come with the mechanical failure of a transmission. Has caused slowing of acceleration which impacted surrounding traffic on a few occasions. Vehicle is scheduled to be inspected by manufacture dealership on morning of 08/27/24.

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)

The contact owns a 2020 Subaru Forester. The contact stated while driving 70 MPH, the vehicle failed to accelerate and then stalled. The driver was able to pull over safely. There were no warning lights illuminated. The vehicle was towed to an independent mechanic, who determined that the failure was due to the thermal control valve and produced DTC codes: P2682 and P26A. The mechanic replaced the cooling gasket and coolant control valve and added coolant. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and assisted with the repair. The approximate failure mileage was 52,395.

While driving temperature light, check engine light, all ADAS lights came on as inoperable (cameras, warning, ABS, BSD/RCTA), no heat (including defrost) available to defrost or for cabin. Appointment 3/13 replaced thermo control valve assembly , coolant bypass valve, intake gaskets, fuel line, coolant, total charges $2070. Luckily had extended warranty I bought, that I had to make a claim on. Dangerous to drive (no camera based safety features available, no defrost for the snowy weather, no emergency braking or other collision safety features on, this affected the entire 'eyesight' system). The engine also had no thermo control regulation during this time, affecting not just then, but possible future performance and early aging due to disregulation.

The thermo control valve on vehicle failed on 2020 Subaru Forester which is causing vehicle to loose acceleration, multiple errors codes displaying on the vehicle instrument dash panel and no heat in the vehicle (see attached photo for reference). The failure of this device could cause a vehicle fire depending on what position/ and or state the thermo valve failed in. There needs to be a manufacturer recall on this particular part as there is numerous amounts of complaints and issues. Subaru needs to make it right with the customer. we need to drive safe vehicles on the road.

On 11/18/2023, as soon as I started the vehicle, put it in reverse and let off the brake to back down the driveway, the car made a loud unfamiliar noise (like bzzzzzt) and suddenly and unexpectedly accelerated on its own. Nothing worked, brakes, automatic gear shift, gas pedal, and steering were all disengaged. It was terrifying to me and I was worried about anyone or anything behind me. At the street corner the car turned somehow (I was trying to steer, but the vehicle was jostling wildly and the steering, brakes didn't work at all), ran over a high curb, knocked over a street sign, and took out the neighbor’s sprinkler system, and then came to a stop, dead!

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.
