2016 Scion IA Transmission and drivetrain Problems

“Transmission whine after used car purchase with 91k miles. Took it to toyota of greenville for diagnostic. Needed a new transmission. Took the car back to ralph hayes toyota of anderson whew I purchased and they replaced the transmission. Since then there has been a transmission grinding and severe vibration while in drive or reverse. I called toyota customer service and asked for a buy back. They declined. I also complained about the dealership and their lack of caring and understanding. Toyota corporate does not care. …”

“Four times now( on different occasions) after shifting the car into reverse the engine made horrible grinding sounds and the car began to lurch violently as I attepmpted to back up. It eventually stalled out completely. On one occasion I was able to have somebody shift the car into reverse so I could look under the hood while the car was grinding and lurching. I saw the engine start to vibrate and then dump forward and then repeat that cycle. I do have video of the event on my phone but I am not able to download it to this lap top.”

When this started it was a once a month problem, then weekly, now it happens daily/hourly. It started at approximately 40,000 miles. This happens while driving on city streets and highway, most of the time at stops and lower speeds but does happen on freeway too.”

During the failure, a loud grinding metal noise was present under the vehicle and an unknown warning indicator displayed. On one occasion, while driving, the failure occurred and caused a second vehicle to crash into the rear of the contact's vehicle. The driver sustained neck, back, and shoulder injuries. In a separate incident, the passenger sustained head, neck, and shoulder injuries from when the vehicle abruptly reduced speed. …”
