2012 GMC TERRAIN Complaints

TO WHOM IT MAY CONCERN: PLEASE NOTE THAT I HAVE OBSERVED MY VEHICLE A PROFOUND AMOUNT OF WATER ENTERING THE VEHICLE SOMEWHERE WITHIN, AT, OR IN VICINITY OF THE FRONT PASSENGER SIDE OF THE VEHICLE AND DRIVER'S SIDE (FRONT). THIS OCCURS DURING RAIN-FALL. MY VEHICLE BEGAN DISPLAYING AN ODOR AND SHOWING WHITE-YELLOWISH COLORED MATTER IN THE CARPET AREA. THE WATER IS NOW DEVELOPED INTO A PUDDLE ON THE PASSENGER - SIDE AND CARPET SOAKED ON THE DRIVER'S SIDE (THE LOST OF FOOTING ON THE DRIVER'S SIDE, MAKES IT SOMETIMES DIFFICULT WHEN DRIVING, AND SHIFTING MY FOOT FROM THE ACCELERATOR TO (AND) BRAKING (TO STEER, AND PERFORMING TURNING MANEUVERS). I HAVE RESEARCHED AND NOTED SEVERAL CONSUMER CHAT PAGES, IN WHICH CONSUMERS HAVE DISCUSSIONS EXPERIENCING THE PROBLEM OF WATER LEAKING INTO THEIR GMC TERRAIN, AND OTHER GMC VEHICLES.

IN MAY 2018 MY REAR CAMERA AND BACKUP LIGHTS STOPPED WORKING. WHEN I WENT TO THE DEALER, THE DEALER TOL ME THAT THE REAR CAMERA WAS BAD AND IT WAS TIED TO THE BACK UP LIGHTS. THEY WOULD NOT FIX IT FOR FREE. I WAS CHARGED $175 DOLLARS TO DISCONNECT THE CAMERA. THE CAMERA SHOULD BE LINKED TO THE BACKUP LIGHTS WHEN IT MALFUNCTIONS. I ALMOST HIT A PERSON BECAUSE THE BACKUP LIGHTS WOULD NOT TURN ON THIS IS A SERIOUS DEFECT. SUNRISE CHEVY SHOULD NOT HAVE CHARGED ME FOR THIS PROBLEM.

SEAT BELT RETRACTORS FAIL TO RETRACT AND BELT CLIP GETS STUCK IN CLOSED DOOR. DEALER FIXED ONCE BUT REFUSES TO FIX AT THEIR COST. I BELIEVE THIS IS A SERIOUS GM DEFECT AND A SAFETY HAZARD BECAUSE A HALF OPEN JAMMED DOOR WILL NOT OPEN.

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. WHILE DRIVING 55 MPH, THE CONTACT STRUCK A DEER. THE DRIVER'S SIDE AIR BAG FAILED TO DEPLOY. THE CONTACT STATED THAT THE IMPACT WAS ON THE PASSENGER SIDE OF THE VEHICLE. THE CONTACT STATED THAT THE SERVICE AIR BAG WARNING INDICATOR WAS ILLUMINATED. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE CONTACT STATED THAT THERE WAS AN ODOR FROM THE AIR BAG PROPELLANT EVEN THOUGH THE AIR BAGS FAILED TO DEPLOY. THE CONTACT STATED THAT THE SEAT BELT OPERATED AS INTENDED; HOWEVER, THE SEAT BELT SEIZED IN POSITION AND WOULD NOT RETRACT EVEN AFTER THE VEHICLE WAS TURNED OFF. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, BUT HAD NOT BEEN DIAGNOSED. NEITHER THE DEALER NOR THE MANUFACTURER WERE CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. THE CONTACT STATED THAT THE DRAINING HOSE FROM THE SUN ROOF LEAKED WATER INTO THE VEHICLE. AS A RESULT, THERE WAS A BUILD UP OF WATER THAT CAUSED A FOUL ODOR AND MOLD. THE VEHICLE WAS TAKEN TO MATAGA BUICK GMC CADILLAC (LOCATED AT 3261 AUTO CENTER DR, STOCKTON, CA 95212, (209) 951-2600) AND THEY UNCLOGGED THE HOSE. THE MANUFACTURER WAS NOTIFIED AND PROVIDED CASE NUMBER: 8-4853270190. THE APPROXIMATE FAILURE MILEAGE WAS 100,000. THE VIN WAS NOT AVAILABLE.

WHILE DRIVING STRAIGHT IN THE RAIN, THE WINDSHIELD WIPERS QUIT WORKING. DIAGNOSIS REVEALED THAT THE WINDSHIELD WIPER TRANSMISSION HAD COME APART AND NEEDED TO BE REPLACED. THIS WAS THE SECOND OCCURRENCE OF THIS ISSUE ON THE SAME VEHICLE. THE FIRST OCCURRENCE WAS IN JUNE 2016

WHILE DRIVING STRAIGHT ON A HIGHWAY IN THE RAIN, THE WINDSHIELD WIPERS STOPPED WORKING. INVESTIGATION REVEALED THAT THE WIPER TRANSMISSION HAD COME APART AND NEEDED TO BE REPLACED. THIS FIRST OCCURRED IN JUNE 2016 WHEN MY VEHICLE HAD 71048 MILES ON IT. THE SAME ISSUE OCCURRED A SECOND TIME IN AUGUST 2018 WITH 111446 MILES ON MY VEHICLE.

I ALSO HAVE A 2012 GMC TERRAIN THAT HAS AN OIL CONSUMPTION ISSUE THAT HAS CAUSED COMPLETE ENGINE FAILURE. APPROXIMATELY 2.5 WEEKS AGO THE CAR WOULDNT START. ENGINE WOULD TURN OVER BUT NOT START. I THOUGHT THAT IT MIGHT BE THE FUEL PUMP. HAD IT TOWED TO MY MECHANIC SINCE IT HAS 87K MILES AND OUT OF WARRANTY. SO I WENT TO CHECK THE STATUS OF THE CAR AND THE FIRST THING I WAS TOLD WAS THERE WAS NO OIL WHEN THEY CHECKED IT. THEY ADDED 4 QUARTS BEFORE TRYING TO DIAGNOSE THE PROBLEM. MIND YOU THE OIL WAS CHANGED 3K MILES AGO AND OIL LIFE MONITOR SAID IT HAD 54% LIFE LEFT. THEY RAN THE CAR FOR CODES AND THE ONLY CODE THAT CAME UP WAS FOR THE TIRE PRESSURE SYSTEM, ALSO AN ISSUE WITH THE TERRAIN. NO ISSUE WAS FOUND WITH FUEL PUMP OR SENSORS. SPARK PLUGS WERE REPLACED DUE TO THEM BEING ALL FOULED UP. THAT DIDNT FIX THE ISSUE SO IT WAS DETERMINED THAT IT MUST BE THE TIMING CHAIN JUMPED. AT THAT POINT I HAD IT TOWED AGAIN TO THE DEALERSHIP I PURCHASE IT FROM. I WAS TOLD IT WOULD BE 125.00 TO RUN A DIAGNOSTIC. FINE. SO I GET A CALL THE NEXT DAY THAT IT WAS INDEED THE TIMING CHAIN. I ASKED THE SERVICE GUY WHAT WOULD CAUSE THIS AND I WAS TOLD POOR LUBRICATION OR LOW OIL PRESSURE. THATS WHEN I STARTED TO EXPLAIN THAT THE FIRST SHOP HAD TO PUT 4QTS OF OIL IN BC IT WAS BONE DRY. I ASKED ABOUT THE VIN SPECIFIC LETTER I RECEIVED LAST YEAR,2017, ABOUT THE OIL CONSUMPTION ISSUE AND ISNT THAT WHY THERE WAS NO OIL AND HENCE CAUSING THE TIMING BELT TO JUMP. HE ANSWERED "NO". THEN TOLD THAT UPON FURTHER INSPECTION, THE VALVES WERE BENT SO WE WERE NOW LOOKING AT 3500 TO FIX OR 6K TO REPLACE THE ENGINE WITH ANOTHER PROBLEMED ENGINE. SO THAT IS WHEN I CONTACTED THE TOLL FREE CUSTOMER SERVICE LINE ABOUT THE SITUATION. THEY TOLD ME TO GO BACK TO DEALERSHIP AND SPEAK TO THE CUSTOMER EXPERIENCE MANAGER.

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. WHILE STOPPED AT A TRAFFIC LIGHT, THE VEHICLE STALLED. THE CONTACT STATED THAT THE VEHICLE RESTARTED, BUT STALLED AGAIN AND THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE CAMSHAFT POSITION SENSOR NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. ADVANTAGE CHEVROLET OF BOLINGBROOK (LOCATED AT 115 S WEST FRONTAGE RD, BOLINGBROOK, IL 60440, (630) 243-4460) WAS NOTIFIED OF THE FAILURE. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 59,000.

WHEN I COME COMPLETE STOP OR WAITING FOR THE LIGHT TO CHANGE. THE TRUCK SHAKES OR ACT IT WANTS CUT ONLY WITH ECO BUTTON IS PUSH ON. THIS DOES NOT HAPPEN WHILE DRIVING ONLY WHEN I COME YOUR COMPLETE STOP. IF THE IS CUT OFF DO NOT HAVE PROBLEM RUNS FINE. DEALER WAS IN FORM HE SAID NOTHING THEY CAN UNTIL THE ENGINE LIGHT COMES ON..
