Consumer Description

EVERY TIME I PARK AND TRY TO SHUT CAR OFF THE CAR REFUSES TO TURN OFF AND GIVES A MESSAGE THAT SAYS SHIFT TO PARK. REQUIRES 20+ ATTEMPTS OF RESTARTING, SHIFTING OUT OF PARK AND BACK INTO IT BEFORE SUCCEEDING. CAR IS CLEARLY IN PARK, NOT ROLLING BUT I'M UNABLE TO TURN OFF CAR FULLY. THIS HAS BEEN OCCURRING THE LAST MONTH OR TWO. I BOUGHT THE CAR BRAND NEW.
