Chronological view of owner reports
Multiple incidences approximately 8 since 2022. Stopped for 8 months with new battery. No issues are recorded in the computer in any of the troubleshooting visits. Normal Sequenced of events: Stopped at a stop light, Start/Stop engages, take foot off brake, start providing gas, car stalls, dashboard lights up, alarms, provides instructions to place the car into park and restart, and the car restarts after that is performed. Danger situations that this has caused: Aggressive car behind not paying attention to the stall and Green light with no one behind and car coming up behind quickly while you are attempting to restart the car. As this cannot be disabled without modification to the car this created a dangerous situation.
I was driving my 2019 Subaru Forester on 5/16 and it was operating normally that morning with no visible warning lights. I got back into the car later and it started fine. While getting onto a local highway, accelerating to highway speeds, multiple warning lights including the check engine light turned on. I was subsequently unable to accelerate and needed to coast to a stop on the closest off ramp, fortunately avoiding an accident. After turning the vehicle off and back on again the check engine light was still illuminated and the car would only make short lurching movements. I needed to have the car towed to a local Subaru dealership (Maita Subaru in Sacramento, CA) and they diagnosed it as a problem with the engine's thermo control valve. This was replaced under warranty and the vehicle is now working normally. The dealership told me this is a known issue with 2019 Foresters and that they've repaired other vehicles under similar circumstances. Multiple other owners have detailed similar experiences on an online forum as well. There does not appear to be a recall but this is a serious safety issue.
The contact owns a 2019 Subaru Forester. The contact stated while driving 20 MPH, the check engine warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the temperature control valve (TCV) to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 67,000. The consumer had to get the vehicle repaired due to this TCV valve issue all the security systems were not functioning causing safety issues.

The vehicle was taken to Auto Zone, where it was diagnosed that the thermal control valve was faulty. The vehicle was then taken to the dealer, where the thermal control valve was replaced. The manufacturer was made aware of the failure. The contact related the failure to Technical Service Bulletin: 09-80-21 (Thermal Control Valve – Design Change) however, the vehicle was not covered under the TSB. The failure mileage was approximately 93,000.
The Subaru Forester 2019 Thermo Control Valve (TCV) fails. It is responsible for cabin temperature but also engine temperature and can result in overheating. There are numerous reports that this is a frequent problem and dealerships want to charge $1200+ to replace. It is certainly a design flaw and should be issued for recall. Mine is available for inspection and has been inspected by the dealership. It was first detected by a check engine light.
2019 SUBARU FORESTER. CONSUMER WRITES IN REGARD ILLUMINATED CHECK ENGINE LIGHT.
Keep getting check engine light. Blue cold engine light stays on. Getting code P26A5 Engine Coolant Bypass Valve 'A' Position Sensor Circuit Range. Parts are unavailable at the dealer. They can’t give me a time frame when they become available.
Thermo electro valve failed, tripping check engine lights in the dashboard. I was told that the vehicle was undrivable until the part, which has been affected by supply chain issues, can be acquired by the dealer.
Check engine light came on and code was for the TCV. The dealership said it would be $1500 to repair and was not under warranty…even though my car is a 2019 Subaru Forester with just 17,000 miles. The Subaru forums on Facebook show that numerous other people are also having this problem.

THE ENGINE HAS OIL LEAKED ON THE LEFT SIDE WHICH I REPORTED ON DEALERSHIP SERVICE LAST NOVEMBER 30 2020 AND WAS FIXED AND REPAIRED AT DECEMBER 8, 2020. I SOMETIMES CHECK AND POP UP THE HOOD TO SEE THE LEVELS OF WIPER WASHER, COOLANT, AND OTHER FLUIDS AT LEAST TWICE A MONTH AND NOTICED LAST WEEK MARCH 4 THAT THERE IS AGAIN OIL LEAKED ON THE SAME LEFT SIDE OF THE ENGINE. I CALLED THE DEALERSHIP TO SCHEDULE SERVICE AND THE CAR WAS BROUGHT AGAIN YESTERDAY TO HAVE IT FIX. IT IS ONLY THREE MONTHS OR MAYBE LESS COZ I DID NOT CHECK THE ENGINE LAST 2 WEEKS OF FEBRUARY DUE TO COLD SNOWY WEATHER. MY WORRY IS THAT THE WARRANTY WILL END THIS NOVEMBER OF 2021 AND OIL LEAKED ON ENGINE WILL COME BACK ALL OVER AGAIN AND EVEN AFTER THE WARRANTY.
