Open the full vehicle complaint log (all categories)The contact owns a 2021 Subaru Legacy. The contact stated that while driving at various speeds during colder weather, the heater failed to operate as intended. Additionally, the Eyesight system was inoperable. The check engine and other unknown warning lights were displayed. In addition, the contact stated that the engine failed to warm up as intended after being started, and the engine temperature was 107°F, which was below the normal engine temperature of 200°F. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the Thermal Control Valve needed to be replaced. The contact related the failure to Technical Service Bulletin: 09-119-24; however, the vehicle was not repaired because the vehicle had a Salvaged Title. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.
Subaru has released a service bulletin regarding concerns with the Thermo Control Valve in specific vehicles. Unfortunately, individuals with vehicles bearing a rebuilt title, including myself, are required to cover expenses exceeding $2,000 out of their own pockets. Despite evidence indicating that the issue with the engine area is unrelated to the vehicle's rebuilt title, Subaru has chosen not to initiate a recall. This unequal treatment of titled vehicle owners is unjust, especially considering that these vehicles have passed all necessary local inspections and regulations to be deemed roadworthy. All vehicles falling within the designated mileage and age parameters should qualify for assistance. It is my belief that a recall must be issued, as this is a mechanical flaw present since the vehicle's initial manufacturing. In the accompanying service bulletin, Subaru acknowledges fault by stating that they have developed a more reliable and durable component. A P26A3 check engine light code.
