EXPERIENCED THE "VEHICLE NOT IN PARK " WHEN SHIFTER WAS IN PARK. ENGINE WOULD NOT TURN OFF BECAUSE ELECTRICAL SWITCH DID NOT RECOGNIZE THE VEHICLE WAS IN PARK. AFTER MANY TRIES I WAS ABLE TO TURN VEHICLE OFF. HAD VEHICLE SERVICED AND SHIFTER WAS REPLACED (3 WEEKS AGO ). TODAY SHIFTER FROZE IN PARK YET CONSOLE INDICATED VEHICLE WAS IN DRIVE. DID NOT REMOVE FOOT OFF OF BRAKE BECAUSE VEHICLE WOULD MOVE FORWARD BECAUSE IT WAS IN GEAR. COULD NOT SHUT OFF VEHICLE BECAUSE IT IS A PUSH BUTTON START/STOP AND FOOT MUST BE OFF BRAKE TO STOP ENGINE. CALLED DEALER FOR HELP. FINALLY WE PUT EMERGENCY BRAKE ON AND PUSHED STOP BUTTON. THE ENGINE TURNED OFF BUT ELECTRICAL SYSTEM WAS STILL ON. HAD VEHICLE TOWED TO DEALER. THEY WILL ADVISE IN A WEEK OR SO THEY ARE SHORT HANDED.
VEHICLE STATES "ACTION REQUIRED - SHIFT TO PARK" EVEN THOUGH VEHICLE IS IN PARK. ACCESSORIES STAY ON AND VEHICLE CONTINUOUSLY SOUNDS WARNING CHIME. THIS PROBLEM OCCURS EVERY TIME THE VEHICLE IS SHIFTED TO PARK AND ENGINE IS SHUT DOWN.
VEHICLE WILL NOT SHUT OFF DUE TO A SHIFT TO PARK MESSAGE WHEN THE SHIFTER IS ALREADY IN THE PARK POSITION.
