2015 GMC TERRAIN Structurebody Problems

First occurrence in September 2015. Rear lift gate acted abnormally, when I was parked,y son opened the lift gate using the normal door handle button, it raised, but as he was loading it lowered onto him. He is small, I had to get out and pull it off of him, it went up and down a couple times and then closed. You cannot stop it from closing down on you if you are trying to load or unload into that compartment. We have had to stop using altogether.

WHILE PULLING INTO A PARKING SPOT VERY SLOW THE VEHICLE ACCELERATED AND DAMAGED CAR IN FRONT THERE ARE TRACTION MARKS SHOWING THE SUDDEN ACCELERATION. THE CAR WOULD NOT STOP UNTIL THE IGNITION WAS TURNED OFF. BECAUSE THE CARS IN FRONT WERE HIT I PLACED THE CAR IN PARK AFTER THE IGNITION WAS TURNED OFF.

THERE IS WATER LEAKING (POSSIBLY FROM THE AIR CONDITIONER) ONTO THE FLOORBOARD OF THE FRONT PASSENGER SIDE. THIS HAS CAUSED MOLD TO FORM AND GROW IN THE CARPETING. IT IS CONSTANT AND IS GETTING WORSE.

THE REAR HATCH WILL FULLY OPEN AND THEN FALLS PART WAY OR FULLY WITHOUT ANY CAUSE. IT HIT ME IN THE HEAD AND BACK AS I WAS NOT EXPECTING THE HATCH DOOR TO FALL. THIS WAS OBVIOUSLY WHILE THE CAR WAS PARKED IN A GARAGE.

WHILE PARKED IN MY DRIVEWAY. THE AUTOMATIC LIFTGATE GOES UP AND THEN FALLS HALFWAY, GOES UP AN THEN FALLS BACK ALL THE WAY DOWN. IT HIT ME AN KNOCKED ME OWN THE FIRST TIME. IT STARTED IN JULY OF THIS YEAR AND DOES IT CONSISTENTLY. I COULD HAVE BEEN SERIOUSLY HURT OR A CHILD COULD EVEN BE CRUSHED AS IT IS EXTREMELY HEAVY. I CANNOT USE THE REAR COMPARTMENT AS THE LIFTGATE WILL NOT STAY OPEN. THERE IS A LAWSUIT ON CERTAIN YEARS FOR THIS VERY PROBLEM AND GMC HAS A TSB UP THROUGH 2014 BUT FOR SOME REASON THE 2015 MODEL IS NOT INCLUDE EVEN THOUGH IT HAS THE EXACT SAME ISSUE. HERE IS A VIDEO OF THE ISSUE. THIS IS ANOTHER TERRAIN AS I DON'T KNOW HOW TO GET A VIDEO OF MINE ON YOUTUBE. HTTPS://WWW.YOUTUBE.COM/WATCH?V=U3NCKL-DETA

FRONT PASSENGER SEAT BELT CHIME COMES ON WHEN THERE IS NOTHING ON THE FRONT SEAT OR ALMOST NOTHING ON THE SEAT. THIS HAS HAPPENED AT LEAST 1/2 DOZEN TIMES OR MORE. I CAN BE DRIVING AND ALL OF SUDDEN COMES ON. IT CAN SCARE ONE ESP 1ST TIME. YOU DON'T KNOW WHAT IS HAPPENING. I THOUGHT I BLEW A TIRE OR DOOR CAME OPEN. MY ATTENTION WAS EVERYWHERE BUT ON 65 MPH TRAFFIC ON FREEWAY. BREAKS ONE'S DRIVING CONCENTRATION. INDEPENDENT OF TEMPERATURE. OTHER PROBLEM I HAVE IS LOTS OF WIND COMES IN ON PASSENGER DOOR. IT IS NOT ALIGNED PROPERLY. GM HAS TRIED A COUPLE OF TIMES WITH NO SUCCESS. VERY ANNOYING AND HARD TO HEAR RADIO ETC.. 3RD PROBLEM IS NAVIGATION,COMMUNICATION CENTER,IT KEEPS DISAPPEARING. IT IS GIVING ME DIRECTIONS SOMEWHERE AND THEN JUST DISAPPEARS AND RESETS. IT HAS BEEN REPLACED ONCE. IT HAS GOTTEN ME STRANDED MORE THAN ONCE....

IN THE EARLY MORNING OF 9-5-15 MY DAUGHTER BEGAN DRIVING HOME FROM PITTSBURGH TO DE. SHE SWERVED TO AVOID AN ANIMAL ON THE PA TURNPIKE, HIT THE JERSEY WALL ON THE RIGHT, ROLLED OVER COMPLETELY TWICE TO THE LEFT, LANDING UPRIGHT IN THE MEDIAN. LUCKILY THE SEAT BELT SAVED HER AND SHE HAD ONLY MINOR INJURIES. HOWEVER THE SIDE AIR BAGS DID NOT DEPLOY. IN FACT ONSTAR CALLED 911 BECAUSE THEIR MONITORING EQUIPMENT SHOWED THAT THE AIR BAGS HAD DEPLOYED, BUT THEY DID NOT. THE VEHICLE WAS DECLARED A TOTAL LOSS. THERE IS NO RECALL ON THIS VEHICLE FOR AIRBAG PROBLEM THOUGH I'VE HEARD THAT THERE SHOULD BE SO I WANTED TO REPORT THIS.
