The contact owns a 2013 GMC Terrain. The contact stated that the vehicle was taken to be inspected however, the contact was informed that the vehicle could not be inspected due to the frame, rocker panel, rear bumper support, and the e-brake cable mounting bracket being extremely corroded. The contact was informed that the parts needed to be replaced before the inspection was completed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 91,276.

The hydraulics that are intended to hold up the rear lift gate have failed. After opening the lift gate and leaning in to get something out of the rear of the car, the lift gate will begin to close and hit or hurt the person that is standing at the back of the car. I have not shown this to a dealer or independent service provider, but it is easily reproducible. Likewise, I have not shown this to a manufacturer, the police, or an insurance representative. There were no warning lamps regarding this issue. The problem just started happening approximately 12 months ago.

TL* THE CONTACT OWNS A 2013 GMC TERRAIN. WHEN THE LIFTGATE WAS OPENED REMOTELY, IT WOULD OPEN AND THEN CLOSE UNEXPECTEDLY. THE CONTACT ALSO STATED THAT THE FAILURE OCCURRED EVERY TIME FOR APPROXIMATELY FOUR MONTHS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE DEALER WAS NOT NOTIFIED. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 86,000.

TAILGATE DOES NOT STAY OPEN. SLOWLY CLOSES. STARTED HAPPENING 3/1/2017. HAPPENS WHENEVER I OPEN REAR TAILGATE FOR ACCESS.

THE BACK HATCH OF MY 2013 GMC TERRAIN HAS PERFORATING CORROSION AND THE DEALERSHIP (WHITE'S MOUNTAIN, CASPER, WY) WON'T REPAIR IT AND NEITHER WILL GENERAL MOTORS DESPITE IT STILL BEING UNDER WARRANTY

THE BACK HATCH DOES NOT HAVE A FEATURE TO REVERSE CLOSING IF SOMETHING (SAY, A CHILD) IS IN BETWEEN THE VEHICLE AND THE CLOSING DOOR. YOU HAVE TO PULL UP ON IT VERY HARD TO GET IT TO STOP CLOSING ON A CHILD AND OPEN BACK UP. IF A PARENT ISN'T THERE TO STOP IT, IT WILL DEFINITELY INJURE (POSSIBLE SEVERELY) A CHILD'S HEAD. *TR

SNOW, MUD AND ALL ROAD DIRT ACCUMULATES INSIDE THE BOTTOM OF ALL DOORS, UP TO THE INSIDE INTERIOR PANEL OF THE DOORS. AM CONCERNED ABOUT RUST IN THE FUTURE AND IF IT'S DUE TO AN IMPROPER SEAL ON DOORS. *JS

ROAD DIRT, SNOW, MUD ACCUMULATES AT INSIDE BOTTOMS OF DOORS ALL THE WAY UP TO BOTTOM OF SPEAKER AREAS. I CAN SEE WHERE IT IS PULLING DOWN THE BOTTOM PANELS. CALLED DEALER AND ASKED FOR GM INFO ON THIS AND NOTHING BACK FROM DEALER. ALSO 2 WEEKS AGO ENGINE LITE CAME ON, TOOK TO LOCAL DEALER FOR REPLACEMENT OF GASOLINE SENSOR? AT 10,000 MILES? ASKED IF I USED CORN GAS? NO, I USE PLUS OR PREMIUM. DOES THIS HAPPEN EVERY 10,000 MILES? ALSO I AM CONCERNED I WILL HAVE RUST ON MY DOORS VERY SOON. *TR

STARTED RIGHT AFTER I PURCHASED THE VEHICLE IN JAN 2013 AND CONTINUES EVERY WINTER. WHEN OUTSIDE TEMPERATURE FALLS BELOW 40 DEGREE'S THE VEHICLE WINDSHIELD MAKES A CRACKING SOUND. I LIKE TO REFER TO IT AS MAKING "POPCORN" SAME SOUND. CONTINUES WHILE DRIVING UNTIL I HEAT UP CAR. I HAVE BROUGHT IT TO DEALER ATTENTION EVEN HAD IT IN SERVICE DEPARTMENT BUT THEY ARE UNABLE TO DUPLICATE SOUND. I HAVE VIDEO AND SENT TO GMC.
