2020 Subaru Forester Engine

While driving my 2020 Subaru Forester at approximately 15 mph, the engine unexpectedly shut off, resulting in an immediate loss of propulsion (vehicle stall while in motion). This created a safety risk because the vehicle was in traffic and could have been struck from behind or lost the ability to accelerate out of danger. No crash occurred and there were no injuries. There were no warning lamps, warning messages, check engine light, or limp mode before, during, or after the stall event. The vehicle later experienced catastrophic engine failure, also without any warning indicators. The vehicle has been inspected by an authorized Subaru dealership. The dealership confirmed the failure and diagnosed crankshaft bearing failure on cylinder 3, and recommended short block replacement along with related engine component replacement (including cam phasers and gaskets/seals). The engine/vehicle remains available for inspection upon request. Manufacturer has been notified through Subaru of America Customer Advocacy. Subaru has offered partial goodwill assistance but has declined further escalation or full remedy. Note: I have video of this showing no engine lights however unable to upload it below. Can send via email if required. Thank you. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

my Subaru suddenly had numerous warning lights go on. Took it to the dealer and they said it was due to a recalled part: thermo control valve. They replaced it for free but said my head gaskets needed to be replaced after checking my oil for $4000 plus. I believe the recalled part caused the head gasket issue and shouldn’t have to pay also the mileage is only 66k

Upon exiting freeway, all lights on car came on including brake light. When placed in park, the engine would rev. If placed in drive, car would drive without gas given. Car towed to Subaru dealership and diagnosed with thermo control valve defect which seems to be a known widespread issue. Thankfully I was located close to a Subaru dealership however if not, this could cause others to be stranded. Given this widespread issue, a recall should occur to fix this issue.

I stopped at a red light. The car's auto shutoff feature turned the car off for the fuel savings. When the light turned green and I went to go, the car tried to start and failed. I had to put it in park and start the car manually.

DEFECTIVE THERMOSTATIC CONTROL VALVE- This part NEEDS to be recalled. Manufacturer has extended the warranty on the part, so it was free to replace. Otherwise, it's a $1600 part. I'm thankful they covered the price, but upset that this KNOWN issue is preventable and they've been letting people continue to be put in danger for four years now?! Incident 1) I was driving 45 mph on a busy street when the car bucked & All engine lights turned on (not helpful to pinpoint a problem) EyeSight turned off (when I needed it most.) The car was worse than dead. I was desperate to get to the shoulder, so I slammed on the emergency lights. Horrified, I realized turning the wheel did almost nothing. I had to lean on the steering wheel to get to the shoulder. When I applied gas it would choppily accelerate, so instead i let the car coast. Since i had no gas, i was stuck in the middle of a side road. I put it in park and turned it off. Someone started walking up from the bad neighborhood, wanted me to get out so he could push the car. I said no, but It took a few minutes to talk him into leaving through the glass of my window. But, this time when i started it up the dash warning lights were off Incident 2) between Oct& Nov 2024 Intermittently all the dash lights turned on, no cruise control or Eyesight. Resolved on its own. No engine trouble acompanied these. Incident 3) Nov 5th, 2024. I started my car, warmed it up, and drove for about 3 minute's when all the dashlights lit up, Eyesight failed, and the whole engine acted like it was on choppy seas. This was at night in a rural area and I was barely able to guide the car to the right shoulder because the accelerator was not working at all. Ended up slashing up my tire and ruining my rim on the shoulder of the road since the car was barely maneuverable. I could have been killed or in an accident - where is the recall on this part?? Mileage at total failure : 46,434

My thermo value went bad on my 2020 Forrester with no symptoms or warning causing me to become stranded in the middle of an extremely busy road. This is seemingly known problem and I'm unsure why Subaru has not been more proactive with this knowledge, not allowing others to end up in the same dangerous situation I was left in. Also, even after having the thermo value replaced, I have no way of knowing if any permanent damage was caused to my engine.

P2682 Engine overheating and engine gauge flashing red due to a recall related to the engine coolant bypass valve. The vehicle stopped and required a tow for $417 to the nearest Subaru dealership to repair. After towing to the dealership they charged 31% of parts to labor and would not eliminate or discount the invoice.

The Thermo Control Valve is faulty and renders the vehicle non-operative. There have been numerous instances in Subaru Foresters in the same make and year.

I was at a red light when the engine shut off and the check engine and several other warning lights came on. After multiple tries I was finally able to restart the vehicle and drive it off the road.

The Thermal Control Valve failed on my car and it’s only 3 years old. This is a common issue and is widely known within the forums. Subaru should recall these valves as they are failing prematurely.

Subaru Forester engine stalls at an intersection due to auto start stop feature of subaru to save fuel, except that this is the second time when engine is idling it lowers the revs and then it stalls when trying to auto start engine; first time the dealer said is battery issue, I replaced the battery at my cost, and this is the second time. It is dangerous because there are oncoming traffic and I have only a split second to turn on my flashing lights. This is a brand new battery install on 9/2024.

While driving on the highway, the engine suddenly stopped and several warning lights appeared on dash. Driver was able to coast to shoulder but could have been a bad accident. It happened again on the way to dealer service center. Dealer reproduced the problem and identified it as a faulty thermo control valve. Dealer fixed it under warranty. Review of web reports makes this seem like a common problem with various Subaru automobiles.
