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.

Dear NHTSA Team, I am writing to report a recurring and distressing issue with my Subaru Legacy 2021 which I believe raises significant safety concerns. Since purchasing the vehicle, I have experienced consistent problems with the battery. Despite replacing the battery five times, the vehicle has repeatedly stopped functioning, including a recent incident where it stalled in the middle of the road. This required me to call law enforcement and a towing service, adding considerable mental and financial stress. These unexpected breakdowns are not only inconvenient but also pose serious safety risks to myself and others on the road. I am concerned that this issue may not be isolated and could affect other Subaru owners as well. I kindly request your assistance in investigating this matter to ensure that appropriate actions are taken to address this potential defect. Please let me know if you need additional information, such as detailed records of the incidents, repair history, or communication with Subaru regarding the issue. Thank you for your attention to this matter. I appreciate your efforts in ensuring road safety and protecting vehicle owners. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A Recall was issued Mar 22, 2024 for a dangerous safety issue. AN AIR BAG That Does NOT Deploy During A Crash CAN Increase THE Risk OF Injury. Remedy Dealers Will Replace THE ODS Sensors ON THE Front Passenger Seat, Free OF Charge. Interim Letters Informing Owners OF THE Safety Risk Were Mailed MAY 17, 2024. Owners Will Receive A Second Letter Once THE Remedy IS Available. Owners MAY Contact Subaru Customer Service AT 1-844-373-6614. Subaru's Number FOR This Recall IS Wra-24. NHTSA issued their Recall for this problem. NHTSA Recall Number24V227000 Recall Status Recall Incomplete, remedy not yet available Now 8 months later Subaru drivers are still forced to drive around with this dangerous defect. This is totally unacceptable, irresponsible and local Subaru dealers have received no part for this repair and have not idea when they will ever get them. NHTSA needs to step in and get answers from Subaru and issue notices to owners with this problem of the danger involved if there is a crash and their passenger is killed because of this delay
