Vehicle has only 1650 miles on it. It is driven conservatively especially so during the first 1000 miles of use “break in period”. Was leaving our neighborhood and the vehicle was searching for a gear, revving and jerking. Check Engine light came on. Limped the vehicle slowly back home and contacted dealer. Had vehicle towed to dealer and they diagnosed the issue as a faulty valve body. Part is on national backorder.
