Open the full vehicle complaint log (all categories)RANDOM AND UNPREDICTABLE FROZEN PASSENGER DOOR. WILL NOT OPEN MANUALLY OR ELECTRICALLY. CAN NOT OPEN !!!!!. AFTER SEVERAL MINUTES OF CONSTANT LOCKING AND UN-LOCKING DOOR HAS RELEASED. HAS HAPPEN FOUR TIMES SINCE PURCHASE IN 2016
NOTICED BLACK FLUID ON LIFTGATE FRAME. SEVERAL DAYS LATER I HAD GREAT DIFFICULTY RAISING THE HATCH. WHEN I RELEASED IT THE GATE FELL VIOLENTELY INJURING MY HAND. IT APPEARS BOTH PISTONS FAILED. MY CONCERN IS THAT HAD THE GATE BEEN IN THE RAISED POSITION AND IT FELL, MYSELF OR A FAMILY MEMBER WOULD HAVE BEEN SERIOUSLY HURT. THIS IS VERY DANGEROUS. THE GATE IS EXTREMELY HEAVY. MY DEALER DID NOT RECOGNIZE THE URGENCY OF THIS PROBLEM NOW MAKING ME WAIT NEARLY A WEEK FOR REPAIR. VEHICLE WAS PARKED IN MY DRIVE AT THE TIME.
