CVT Transmission Failure. Failure occurred at approximately 66,706 miles on 5/16/25. The Check Engine and AT Temp lights appeared in the instrument cluster. The driving conditions when this happened were a safety concern. First, the vehicle would crawl, shutter, and almost stall with high RPMs when attempting to climb a hill. Second, on a level surface at any given time the vehicle would not respond then lunge forward unexpectedly. The vehicle was inspected by a Subaru Dealership and the diagnosis was "Internal failure of transmission". The transmission needs to be replaced. The same driving conditions and error codes were experienced by an AAMCO Transmission repair facility. The diagnosis was codes P0843 and P0867 present prompting the transmission to be replaced. This repair was completed on 6/4/25. The failed transmission is no longer available.

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.
