ENGINE
Vehicle: 2021 Subaru Legacy Base 2.5i Mileage:~65,000 miles My engine suddenly began making loud internal knocking/tapping noises with no warning lights, no overheating, and no prior symptoms. The vehicle immediately became unsafe to operate. I had it towed to a Subaru dealership, where technicians confirmed the noise was coming from inside the engine and recommended a full engine replacement. The failure happened without any warning indicators, misfires, overheating, or oil pressure warnings. All diagnostics (including compression and leakdown) were clean, and the vehicle has been properly maintained. Subaru of America acknowledged the internal failure but only offered $1,000 goodwill

ELECTRICAL SYSTEM

60,000 miles

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

POWER TRAIN
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

ENGINE
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

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
