2010 GMC TERRAIN Complaints

SITTING IN CAR WITH KEY IN CUP HOLDER AND THE ENGINE TRIED TO CRANK UP ALL MY ITSELF. CAR TAKEN TO DEALERSHIP AFTER THE 3 RD TIME HAPPENING,DEALERSHIP CLAIMS THEY CAN NOT FIND AN ISSUE WITH THE CAR. TODAY CAR HAS DONE THE SAME NHING THREE TIMES ALREADY.

TL* THE CONTACT OWNS A 2010 GMC TERRAIN. WHILE OPERATING THE VEHICLE, THE DEFROSTER AND DEFOGGER SYSTEMS MALFUNCTIONED AND BECOME INOPERABLE. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 09V489000 (VISIBILITY). THE CONTACT STATED THAT THE VEHICLE EXPERIENCED THE SAME FAILURE LISTED IN THE RECALL. THE FAILURE MILEAGE WAS 50,000.

I PURCHASED THE VEHICLE 12/13/09. BEGINNING AROUND 3/26/10, I FIRST NOTICED THAT MY HATCHBACK WAS OPEN WHEN I WENT TO GET IN TO GO TO WORK, AND IT HAD BEEN PARKED OVERNIGHT. THIS HAS HAPPENED IN THE VICINITY OF 15-20 TIMES SINCE THAT DATE. I THOUGHT SOMEHOW I WAS ACCIDENTALLY PUSHING THE RELEASE BUTTON ON THE KEY; HOWEVER, I OFTEN WOULD NOT HAVE HAD THE KEY IN HAND OR IN MY POCKET TO DO SO ACCIDENTALLY. IT LAST HAPPENED ABOUT 2 WEEKS AGO, I WALKED OUT TO MY PARKED TERRAIN IN THE GARAGE AT MY APARTMENT, AND THE LIFTGATE WAS WIDE OPEN. NOTHING HAS BEEN STOLEN YET, BUT I AM CAREFUL NOT TO LEAVE ANYTHING IN IT OR AT LEAST IN SIGHT. *TR

WE HAVE A 2010 GMC TERRAIN AND THE HATCH DOOR OPENS ON ITS OWN. IT OCCURS WHILE PARKED AND WHILE DRIVING, HAPPENING SEVERAL TIMES A WEEK AND OFTEN SEVERAL TIMES A DAY. WE HAVE CLOSED AND LOCKED THE DOOR/CAR WITH THE BUTTON IN THE CAR, WITH THE KEY AND MANUALLY AND IT STILL OCCURS. THE HATCH LATCH HAS BEEN REPLACED BUT THE PROBLEM CONTINUES. NOT ONLY COULD SOMETHING FALL OUT OF THE BACK AND CAUSE AN ACCIDENT, IT LEAVES US OPEN TO THEFT AS WELL AS BEING A NUISANCE AND A WORRY. *TR

2010 GMC TERRAIN STARTED MAKING A RATTLING NOISE AND SHAKING A STOP, LIKE A ROUGH IDLE, TOOK IT TO THE DEALERSHIP TO GET IT FIXED UNDER WARRANTY, HAD TO REPLACE WATER PUMP, BALANCE SHAFT CHAIN AND TENSIONER REPLACED INTAKE AND EXHAUST. CAMSHAFT POSITION ACTUATORS AND BOLTS REPLACED HIGH PRESSURE, FUEL PUMP REPLACED V/C GASKET TIMING CHAIN TENSIONER AND LEFT TIMING CHAIN GUIDE. THAT WAS REPLACED 09/07/13 IN WARRANTY. NOW IT IS 3/09/15 AND THE SAME PROBLEMS HAVE COME UP AGAIN AND MY CAR IS CURRENTLY IN THE SHOP AT THE DEALERSHIP , THAT MEANS THERE IS A SERIOUS PROBLEM WITH THIS MAKE OF ENGINE AND IT SHOULD BE RECALLED BEFORE SOMEONE GETS HURT BECAUSE OF IT. *TR

DRIVING BACK FROM A TWO HOUR TRIP AT APROX 55 MPH OUR 2010 GMC STARTED FLASHING "REDUCED ENGINE POWER" WITH THE CHECK ENGINE LIGHT, AND "SERVICE STABILITRAK" WITH THE STABILITRAK LIGHT. SPEED DROPPED DOWN TO ABOUT 30 MPH WITHOUT CONTROL. THE CAR WAS IDLING HEAVING WITH RMPS JUMPING. WE PULLED OVER TO THE SIDE OF THE ROAD AND RESTARTED THE CAR, THE ONLY LIGHT THAT REMAINED ON WAS THE CHECK ENGINE LIGHT. SPEED CONTROL WAS RESTORED. BY THE TIME WE MADE IT HOME, APROX 20 MILES, THE CHECK ENGINE LIGHT TURNED OFF. THEN A COUPLE WEEKS LATER AGAIN, TWICE IN ONE NIGHT, BACK TO BACK. I CALLED THE DEALER FOR AN APPOINTMENT BECAUSE I ASSUMED IT WOULD BE COVERED BY A GMC WARRANTY, THEY DID NOT HAVE AVAILABILITY FOR 7+ DAYS. THE NIGHT BEFORE MY APPOINTMENT IT HAPPENED AGAIN BUT DID NOT CORRECT ITSELF AND WE HAD TO DRIVE IT TO THE DEALERSHIP AT 30 MPH. I JUST RECEIVED THE NEWS, $800 LATER, IT NEEDS A NEW THROTTLE BODY, EXHAUST CAM SOLENOID AND ANOTHER REPAIR TO THE CAMSHAFT. I DO NOT HAVE THE PAPERWORK BACK FROM THE DEALER YET FOR ADDITIONAL DETAILS, BUT AM DISAPPOINTED THAT THIS IS A COMMON PROBLEM WITH THE 2010 GMC TERRAINS AND THEY TAKE NO RESPONSIBILITY FOR THE REPAIRS. THIS SHOULD BE A RECALL. THERE IS A LOT OF POTENTIAL DANGER TO HAVING YOUR SPEED DROP WITH NO WARNING OR CONTROL.

DRIVING THE VEHICLE DURING THE HEAVY RAIN AND NOTICED THAT DEFOGGING/DEFROSTING OF THE WINDSHIELD ARE NOT BLOWING THE AIR ON IT FROM DASHBOARD VENTS.VISIBILITY WAS VERY LIMITED AND HAVE TO USE TOWEL TO CLEAN THE WINDSHIELD SO I CAN SEE WHERE I'M GOING.MAKE A STOP AND NOTICED THAT THE AIR IS ONLY COMING FROM VENTS TO THE FLOOR AND FRONT NOT MATTER WHAT THE CONTROL IS SET TO.WAS LUCKY TO GET HOME SAFELY BUT DO NOT WANT TO EXPERIENCE THIS SITUATION AGAIN.TODAY DROP CAR AT GMC SERVICE WHERE THEIR FOUND THAT MODE DOOR ACTUATOR IS BAD CAUSING DEFOGGING/DEFROSTING FUTURE ON THE CAR TO BE INOPERATIVE IF IT IS NOT REPLACED.I THINK THAT IS RESPONSIBILITY OF GM TO CORRECT THIS PROBLEM FOR ALL OWNERS OF GMC TERRAIN WHO EXPERIENCE SAME PROBLEM AT NO COST TO THEM FOR THEIR SAFETY AND SAFETY OF ALL USING PUBLIC ROADS. *JS

THE DRIVER AIR BAG LIGHT WENT ON AND MY CAR IT'S NEVER BEEN IN AN ACCIDENT. I THINK THIS SHOULD BE A MANUFACTURER DEFECT.
