While driving a message of service shifter displayed and vehicle went like on park mode but in d shift. Car was in motion and became stationary. Shift lights came on. All wheels were locked, service engine light on. Turning car off and back on didn't help. I was unable to move the shift from d to any other shift. It was very scary as I was on heavy traffic road, unable to move the car in the middle lane during work rush hour. It had to be towed to the dealer, tow guy had issues getting into the flat bed as the wheels were fully locked. Awaiting a diagnosis.
