2020 GMC TERRAIN DOOR LOCKING AND UNLOCKING ISSUES.
SOMETIMES IT LOCKS AND SOMETIMES IT DOESN'T LOCK AT ALL. YOU CAN'T TELL UNLESS YOU CHECK DOORS. YOU'LL HEAR THE LOCKING SOUND BUT ITS DOESNT MEAN IS LOCKED.
UNRESOLVED AFTER MANY DEALER VISITS AND FEW SOFTWARE UPDATES AND PARTS REPLACE.
KEYFOBS DON'T WORK
MUST CLIMB FROM TAIL GATE TO OPEN DRIVER OR FRONT PASSENGER DOOR.
ACCORDING TO GM DEALERS THIS IS A VERY COMMON ISSUE THAT HAPPENS DUE TO 5G WI-FI CELL TOWERS AND MILITARY BASES FREQUENCIES.
WE ALSO HAVE A RECORDING IN REGARDS TO THIS FROM A GM DEALER SERVICE MANAGER/AGENT.
THIS ISSUE COULD BE HAPPENING TO ANY GM VEHICLE
