2012 GMC TERRAIN Complaints

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. WHILE IDLING, THE VEHICLE SUDDENLY STALLED AND SHUT OFF. WHILE DRIVING AT VARIOUS SPEEDS, THE DASHBOARD LIGHTS SUDDENLY BEGAN TO DIM AND THE SPEED REDUCED TO 15 MPH. THE "ENGINE POWER REDUCED" MESSAGE APPEARED. THE VEHICLE WAS TAKEN TO THE DEALER ON SEVERAL OCCASIONS AND THE ELECTRONIC CONTROL MODULE WAS REPLACED AND THE THROTTLE BODY WAS CLEANED, BUT THE FAILURES CONTINUED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS 32,000.

SUDDEN UNINTENDED ACCELERATION WHEN VEHICLE SHIFTED FROM PARK TO DRIVE, RESULTED IN EXTREME HIGH SPEED ACCELERATION AND NO CONTROL OF VEHICLE. THIS RESULTED IN A HIGH IMPACT CRASH INTO GARAGE SIDE WALL. ALSO AIR BAG DID NOT DEPLOY. ASSUME THROTTLE WIDE OPEN CAUSING SUDDEN ACCELERATION. INSURANCE REPORT , AND POLICE REPORT PENDING

AT LOW IDLE OR WHEN BACKING UP AND ACCELERATING VEHICLE THE ENGINE STALLS. THIS TYPICALLY OCCURS AFTER DRIVING CAR FOR 10-15 MINUTES. ENGINE LIGHT APPEARS. IT WILL CONTINUE TO STALL UNLESS HOLDING DOWN BRAKE & ACCELERATOR AT SAME TIME. STOPS STALLING WHEN SPEED INCREASES, BUT STALLS ON LOW SPEEDS & BACKING UP CONTINUALLY. CODE INDICATES CAMSHAFT ADJUSTER SENSOR. FIRST SENSOR REPLACED. PROBLEM OCCURRED AGAIN IMMEDIATELY AFTER LEAVING GARAGE. SECOND SENSOR REPLACED. PROBLEM OCCURRED ONCE AGAIN! MECHANIC THINKS IT COULD BE GROUND WIRING ISSUE IS BURNING UP THE CAMSHAFT SENSORS. THE CAR IS NOT SAFE TO DRIVE.

SUMMARY: I HAD TO DECIDE TO BRAKE OR SHOOT THROUGH A YELLOW LIGHT, GOING ABOUT 35 MPH, I BRAKED! ALL OF A SUDDEN I HEARD A CLUNK AND THEN ALARM DING FROM THE DASH AS WELL AS MESSAGE "SERVICE STABILTRAK" THEN "REDUCED ENGINE POWER". I WAS UNABLE TO GO ANY FASTER THAN 25MPH. I DROVE IN THIS MODE FOR ABOUT 2 MILES TAKING THE BACK STREETS TO MY DESTINATION. AT DESTINATION SHUT VEHICLE OFF TO SEE IF THIS WOULD RESET SOMETHING, IT DID! IT WAS SUPER SCARY. SO NOW TERRIFIED TO BRAKE HARD.

I WAS TRAVELING ON THE TOLL WAY AND WENT TO PASS A VEHICLE GOING BELOW THE SPEED LIMIT. UPON ACCELERATION (APPROX 53 MPH), I HEARD A MUFFLED POP IN THE ENGINE COMPARTMENT AND WHITE SMOKE TRAILED THE VEHICLE. NO WARNING LIGHTS WENT OFF PRIOR AND I DO NOT RECALL SEEING ANY AFTER THE "POP". I STOPPED THE VEHICLE AND TURNED OFF THE ENGINE, OPENED THE HOOD TO FIND FLAMES UNDER THE ENGINE IN VICINITY OF THE OIL PAN. I WAS UNABLE TO PUT OUT THE FLAMES AND THE FIRE CONSUMED THE VEHICLE. I VEHICLE WAS WELL MAINTAINED AND HAVE NO IDEA WHAT THE ORIGIN OF THE FIRE WAS.

MY CHECK ENGINE LIGHT CAME ON ABOUT A MONTH AGO AND WAS SERVICED FOR A PROBLEM WITH THE CAMSHAFT. AFTER GETTING MY GMC TERRAIN BACK I NOTICED THAT ON OCCASION THE RPM WOULD SHOOT UP WHILE DRIVING AND THEN CRASH BACK DOWN CAUSING ALMOST A JERKING MOTION (IT HAS HAPPENED IN ALL TYPES OF SCENARIOS I.E. WHILE DRIVING ON THE HIGHWAY, BACK ROADS (ALL WHILE AT A STEADY SPEED) AND THEN FINALLY YESTERDAY 3/5/2016 WHILE BREAKING AS I APPROACHED A STOP SIGN.) NOW THIS MORNING (3/6/2016) I WENT OUT TO START MY CAR AND IMMEDIATELY AFTER IT TURNED OVER THE ENGINE WAS MAKING A VERY LOUD NOISE THAT I CAN ONLY DESCRIBE AS THE SOUND OF AN AIRPLANE ENGINE WITH A LIGHT KNOCKING SOUND. I STOOD THERE UNSURE OF WHAT TO DO AND THE CAR JUST TURNED OFF. I WENT INSIDE, GOT MY HUSBAND, STARTED IT AGAIN THIS TIME WITHOUT THE NOISE, BUT THE DASHBOARD WAS FILLED WITH LIGHTS ON- CHECK ENGINE, TRACTION CONTROL, AND A WARNING SERVICE STABILITRACK. I LET IT RUN FOR ABOUT 5 MINUTES, TURNED IT OFF, AND RESTARTED IT. THE CHECK ENGINE LIGHT IS NOW OFF, BUT THE TRACTION CONTROL AND STABILITRAK WARNING REMAINED ON. I DECIDED TO TRY TO DRIVE THE CAR AROUND THE BLOCK TO CHECK IT OUT AS OF COURSE IT'S SUNDAY AND I CAN'T GET IN TOUCH WITH THE SERVICE DEPARTMENT AND ALSO BECAUSE I AM THE PRIMARY DRIVER OF TWO CHILDREN UNDER 10. I BACKED OUT OF THE DRIVEWAY, AND WENT INTO DRIVE AND THE CAR STALLED AGAIN. I GOT IT STARTED AND GOT HALFWAY BACK UP MY DRIVEWAY BEFORE IT STALLED AGAIN. TRUTHFULLY, I AM SCARED TO EVEN TRY TO DRIVE IT NOW, AND IF I AM BEING HONEST I DON'T THINK THAT THE CAR WILL MAKE IT TO THE DEALERSHIP (1HR. AWAY BY HIGHWAY) WITHOUT STALLING. I'VE NOTICED OTHERS WITH SIMILAR COMPLAINTS ON GM/CHEVY ALL MAKES AND MODELS, AND DON'T UNDERSTAND WHY THIS ISSUE IS NOT BEING RESOLVED. WHAT ARE THEY WAITING FOR- A FAMILY OF 4 DRIVING ON A HIGHWAY CAUSING AN ACCIDENT BECAUSE THEIR CAR STALLED? DEATH?

I HAVE HAD ISSUES WITH THIS VEHICLE EVER SINCE ITS PURCHASE 01/2015. I TOOK THE VEHICLE IN FOR SERVICE AND WAS TOLD THE SERVICE CONTRACT WOULD NOT COVER MY ISSUE AND THAT THE ISSUE WAS CAUSED BY LACK OF MAINTENANCE, WHICH IS NOT THE CASE AS I MAINTAIN THE OIL IN THIS VEHICLE AND EVEN HAD TO PURCHASE A NEW BATTERY FOR THE VEHICLE RECENTLY.THIS CAR'S ENGINE REPEATEDLY STOPS, ESPECIALLY WHEN APPROACHING A RED LIGHT OR STOP SIGN OR AT THE MOMENT OF ACCELERATION. I HAVE HAD TO AVOID MANY ACCIDENTS DUE TO PEOPLE DRIVING UP ON ME BECAUSE I SHOULD HAVE BEEN ACCELERATING AT THE TIME BUT MY CAR TURNED OFF. THE BATTERY WOULD DIE ON THIS CAR ON A WEEKLY BASIS WHICH CAUSED ME TO PURCHASE A BATTERY AND THERE IS STILL NO PROGRESS IN THE VEHICLE. THE MOTOR KNOCKS BADLY UPON STARTUP, ESPECIALLY IN THE MORNINGS. THE ENGINE IS VERY WEAK AFTER AN INDEPENDENT DIAGNOSTIC CHECK. AND JUST LAST WEEK, AS I WAS DRIVING ON THE HIGHWAY AT NORMAL SPEEDS, THE MUFFLER SHIELD BROKE, FELL, AND BEGAN SCRAPING AGAINST THE HIGHWAY. THERE ARE ELECTRICAL ISSUES AS WELL AS THE LIGHTING IN THE CAR GETS DIM WHEN WE ARE IN THE DARK BUT BRIGHT WHEN THE SUN IS OUT. ALSO, THE SEATBELT FOR THE PASSENGER'S SIDE CONSTANTLY RINGS SENDING A NOTIFICATION THAT THE SEATBELT NEEDS TO BE LATCHED, EVEN WHEN NO ONE ELSE OR NOTHING ELSE IS IN THAT SEAT. I FEAR THAT ONE DAY I MAY NEED THAT AIR BAG AND IT MIGHT NOT WORK BECAUSE THE SEATBELT APPEARS TO BE FAULTY. ALSO, ANOTHER ISSUE, WHICH IS NOT NECESSARILY A SAFETY ISSUE, BUT AN EXTREME NUISANCE AND ALSO MAYBE AN ELECTRICAL ISSUE IS THE CAR RADIO AND VOLUME WILL FREEZE AT ANY GIVEN MOMENT AND THE CAR HAS TO BE STOPPED AND IDLE FOR A PERIOD OF TIME BEFORE THE RADIO IS ACTIVE AND ABLE TO TURN CHANNELS AGAIN. THE SAFETY ISSUES FOR THIS CAR ARE REAL AND I AM IN FEAR THAT I WILL GET HIT FROM BEHIND DUE TO THE FAULTY ENGINE.

EXCESSIVE OIL BURN WITH NO WARNING OF LOW OIL UNTIL ABOUT ONE QUART LEFT IN ENGINE. ONLY CHECK ENGINE LIGHT CAME ON. YES THE MANUAL SAYS CHECK OIL AT EVERY FILL UP BUT AFTER OWNING MANY CARS OVER 38 YEARS WITHOUT THIS PROBLEM IT WOULD SEEM THE MANUAL WAS WRITTEN TO PROTECT GM. I WOULD NOT HAVE PURCHASED THE VEHICLE IF I KNEW I HAD TO PUT IN A QUART OF OIL EVERY 1500 MILES. GOOGLE THIS. IM NOT THE ONLY ONE.

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS BROUGHT TO THE DEALER FOR DIAGNOSTIC TESTING, BUT THE DETAILS COULD NOT BE PROVIDED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE BEGAN TO JERK AND HESITATE AND A LOUD ABNORMAL KNOCKING NOISE WAS HEARD. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE VEHICLE WAS IN WORKING CONDITION. THE CONTACT STATED THAT THE ENGINE FAILED SHORTLY AFTER, MAKING THE VEHICLE INOPERABLE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS 135,000.

WITHIN TWO DAYS' TIME, MY 2012 GMC TERRAIN STALLED FOUR DIFFERENT TIMES, ALL AT LOW SPEEDS. THE FIRST TIME WAS BACKING OUT OF THE DRIVEWAY; THE OTHER THREE HAPPENED THE FOLLOWING DAY STARTING UP FROM CITY STREET INTERSECTIONS. MY CONCERN IS BEING REAR-ENDED IN THOSE SITUATIONS, OR BEGINNING TO MAKE A LEFT HAND TURN IN FRONT OF ONCOMING TRAFFIC THINKING YOU HAVE ENOUGH TIME AND THEN HAVING THE CAR STALL. ANOTHER CONCERN IS HAVING THE STALLING ISSUE OCCUR AT HIGHER SPEEDS, ALTHOUGH THAT NEVER HAPPENED TO ME. I TOOK THE CAR INTO THE DEALERSHIP ON THAT SECOND DAY, AND THEY REPLACED THE INTAKE CAMSHAFT POSITION ACTUATOR SOLENOID VALVE. THE PROBLEM HAS NOT REPEATED ITSELF SINCE. THANK YOU.
