2020 Subaru Forester

While driving, the 2020 Forester, the check engine light, collision light, eyesight function lights all went on at the same time. I brought vehicle to check diagnostics and it is showing Engine Coolant Bypass Valve "A" Control Circuit low in Power Train System. Their were no messages prior to all the lights turning on and I was able to bring into the dealer for oil change but not able to make an appointment for repair for a few days from now

For the 3rd time in less than 3 years my windshield crack from a small pebble hitting it. Either Subaru is making very thin windshield glass, or the material used is not sufficient to suppress small pebbles and causes the windshield to crack, often. The latest crack happened July 25, 2023 in the PM with a small 1/4 inch crack, by morning it had grown to over 2 feet. It seems to me there is a design flaw here.

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.

The contact owns a 2020 Subaru Forester. The contact stated that there was a chip on the front windshield that was not caused by an impact. The front windshield was cracked. The contact called the local dealer and was referred to an auto glass shop. The vehicle was taken to the auto glass shop that replaced the front windshield, but the failure recurred. The contact stated that while her son was occupying the vehicle, he noticed that the front windshield was cracked. The vehicle was not repaired. The manufacturer was contacted. The failure mileage was 25,000.

Error code (P26A3?)for - Engine Coolant Bypass Valve. Causes the "Check Engine" light to come on and automatically disables ALL of the safety and collision mitigation systems. The Engine Coolant Bypass Valve failure is common and a known issue and Subaru has already updated the part on newer vehicle models. The common failure of the coolant bypass valve should not be disabling the safety features and the collision avoidance systems.

The contact owns a 2020 Subaru Forester. The contact stated that while driving approximately 70 MPH, the accelerator pedal was depressed, and the vehicle started to lose motive power. The check engine warning light was illuminated. The vehicle was steered to the side of the road where the vehicle then stalled. The vehicle was restarted approximately 15 minutes later. The vehicle was towed to a dealer where it was diagnosed that the thermal control valve and electric water pump needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 13,000.

I was driving on a paved two lane rural route and hit a small bump in the road. Immediately, my check engine light came on and all the safety features turned off. Control panel showed multiple safety features off and the Sport mode indicator light blinking. My car only has 17K miles on it and I have had it just over a month. I was able to drive it safely home and when I called the dealership the next morning I was told I could continue to drive it until the service appointment six days later. When I got home, my husband checked it with his CEL reader and got the code for the temperature control valve (an issue known by Subaru). This was confirmed by the dealership and I was told after having driven it for several days that it should not be driven. The repair is being covered under the power train warranty.

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).
