2021 SUBARU LEGACY — Problems, Recalls & Safety Data

See attached document for complaint.

Car intermittently will studder and not go into first gear or go into second gear dangerously having car bog down and almost stall and then it violently downshifts having car RMP Hague go very high then slip and have no power to wheels and then a few seconds later go into second gear violently taking off again. Have tried taking issue to dealer but won’t even look unless check engine light comes on. Which it sometimes will for this issue and will shut back off before my short drive to dealership. Very frustrated especially being my first new car paying monthly to have this problem

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.
