Daily the automatic transmission will erratically and forcefully downshift at highway speed. When changing Driving Modes the transmission display on the dash has numbers disappear and the transmission downshifts with great force which has lead to injuries. After sitting for more than a few hours the transmission will not go into reverse at first but will then violently shift into reverse after several minutes. These issues began not long after we purchased this vehicle new. The service manager at the dealership the vehicle was purchased from when I told him about these problems told me that I donât understand how a 10 speed transmission works. Sometimes the driverâs seatbelt will not buckle.
