“DRIVER DOOR OCCASIONALLY DOES NOT UNLOCK WITH THE DOOR HANDLE. STANDARD OPERATION IS TO PULL HANDLE TWICE TO UNLOCK AND OPEN THE DOOR. THIS DOES NOT ALWAYS WORK, AND I CAN'T GET OUT OF THE CAR, WITHOUT FINDING THE KEYFOB, OR USING THE CENTRAL LOCKING BUTTON ON THE DASH. THIS IS A SAFETY ISSUE. IF THE BATTERY WERE TO FAIL, OR IF IN AN ACCIDENT AND THE POWER IS LOST, THE DOOR WON'T OPEN. I HAVE VIDEOS OF THE FAILURE. THIS OCCURS WHEN PARKED, VEHICLE IS TURNED OFF, AND ATTEMPTING TO EXIT THE CAR. IT HAS OCCURRED AT HOME, AND AT SEVERAL OTHER LOCATIONS. HAS OCCURRED TO ME BETWEEN 06-2018 AND 9-2018, AND WEATHER HAS NOT BEEN COLD.”
