2012 GMC TERRAIN Unknown Or Other Problems

Liftgate automatically closing and failure to remain open causing a safety hazard for anyone standing at the liftgate.

I think the manifold on GMC Terrain need to be on a recall because mine already cracked.

My vehicle is 2012 GMC Terrain. Oil changes on my vehicle we kept up and i had no major issues with this vehicle. I had an oil change done about a month before i went to start my car and all the lights came on and my car would rumble and wouldn't stay started and was longer drivable. After towing it a service shop they stated the following: The timing chains are damaged, skipped teeth, metal debris found in oil and screen of intake and exhaust camshaft solenoids due to many oil leaks coming form engine and serious internal issues w/engine we recommend replacing the engine. Est cost, 11,061. I had no reason to think my car was in any trouble, as it was driving fine with no problems. I received no such recall letter or phone call and no mention from the dealership i bought the car from back...

My 4 cyl. AWD GMC Terrain has had excessive oil use which caused premature failure of the timing chain, loss of power/compression, blown engine, damage to exhaust manifold, cellinoids, and melted the catalytic converter. Its was a road safety, poor emissions due to failed catalytic converter. Headlights are too bright for oncoming traffic at night. Another road & safety hazard. Auto warranty is refusing to cover parts listed above caused by the timing chain and excessive oil consumption problems.

My lift gate has been failing since i bought it used from a local dealership. It's closed down on my mom's leg when she was situating luggage that she'd put in. It has tried closing on myself as well each time i opened it(4×) & when I tried to stop it by pushing up on it, it only forces itself down not up. This is very dangerous & had an old recall from GM motors due to the struts in the lift gate was faulty & made by stabilize whom had numerous lawsuits from other manufacturers due to injuries & deaths. The dealership refuses to fix it for free even though they knew the issue with it cause it was brought to their attention by their detail guy whom had it close on him as well. This a is major issue that needs addressed asap. And not at the expense...

Drive side frame is rotted out which has allowed rear driver side control arm for the wheel to freely move. The passenger side is completely fine. Contacted gm and was told it has to be taken to a dealer to be diagnosed. It’s easy to see the issue I have pictures that can be provided. This car should not be rotted out frame was perfect 8 years ago with no rust and has been washed twice a week during winter to remove salt with undercarriage car wash.

The timing chain is failing on my 2012 GMC Terrain. It’s dangerous to drive and it started without warning (to me). It’s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? Many thanks.

The rear tailgate on a 2012 GMC Terrain has auto lift and close. The tailgate opens, but wont stay open then closes hitting you in the head. The heavy tailgate comes down hitting you in the head, and it takes a lot to hold the gate up. I called the dealer who said it could be the power lift. He said there was a previous recall to fix the same issue, but that part is not holding. I spoke with the dealer and found issued on line. No warning lamps or messages appeared.

My oil in my truck is depleting rapidly. It do not last 3months or 3k miles. Sometimes I'm barely 1800 miles in and I'm low on oil

My timing chain went out due to losing oil to quickly.

CAR BURNS OIL QUICKLY. I HAVE TO GET FREQUENT OIL CHANGES. TWO WEEKS AGO OIL HAD LEEKAED INTO MY CAR.

THE LEFT FRONT TIRE PRESSURE SENSOR NO LONGER WORKS. MY HUSBAND BOUGHT A NEWER CHEVY AND THE SAME SENSOR NO LONGER WORKS. FRIENDS HAVE THE SAME EXACT PROBLEM WITH THE SAME SENSOR ON THEIR GMC/CHEVY VEHICLES. SENSOR LIGHT WARNS OF THE SENSOR NOT WORKING FOR THE LEFT FRONT TIRE PRESSURE. LIGHTED SIGN ON DASHBOARD SAYS "SERVICE TIRE MONITOR SYSTEM". WHEN YOU ENTER MENU AND SELECT TIRE PRESSURE IT SAYS LEFT FRONT TIRE 0. MANUFACTURER DEFECT?

THE BACK GATE COMES DOWN ON YOUR HEAD WHEN YOU ARE TRYING TO PUT THINGS IN BACK OR TAKE THINGS OUT, ALMOST IMMEDIATELY. IT HAS HIT MY HEAD SEVERAL TIMES CAUSING IMMENSE PAIN AND A MIGRAINE. IT STARTED IN JULY OF 2019 AND WAS SLOW AT FIRST. NOW IT HAPPENS ALMOST IMMEDIATELY.. IT HAS HIT MY HEAD SEVERAL TIMES AND MY SON. I SAW THERE WERE PROBLEMS WITH THIS MODEL WITH THIS ISSUE. GMC TELLS ME IT IS NOT COVERED.

THE VEHICLE HAS EXCESSIVE OIL CONSUMPTION. I HAVE TO KEEP ADDING MOTOR OIL A COUPLE WEEKS AFTER DOING OIL CHANGE.

SEVERAL TIMES IN 3 YEARS, THE DEALERSHIP CAN NOT DUPLICATE THE PROBLEM LOSS OF POWER STARTS RUNNING SLOW, WONT GO OVER 20 MPH, CHECK STABILITY LIGHT COMES ON, CHECK ENGINE LIGHT STARTS BLINKING, ACTS LIKE MISFIRE OR NO FUEL IN VEHICLE, STARTS ANYWHERE AT ANY TIME, VERY UNSAFE AND SCARY. AT LEAST TAKEN TO A CERTIFIED DEALERSHIP 7 OR 8 TIMES AND EVERY TIME THEY DO SOMETHING DIFFERANT , YET THE PROBLEM PERSISTS! THE VEHICLE CAN BE STATIONARY AT RED LIGHT AND BIG OR WHILE DRIVING GOING 45 OR 65 AND DROP TO 20 MPH AND NOT WANT TO GO, I PUSH THE GAS PADDLE TO FLOOR AND IT DOES NOTHING. THIS HAS BEEN INTERMEDIATE AND A PROBLEM SINCE MONTH 3 OF BUYING MY VEHICLE. THIS IS NOT SAFE AND THE DEALERSHIP HAS BASICALLY GIVIN UP ON ME AND MY VEHICLE.

TIME CHANGING ACTUATORS.

MY CAR OIL CONSUMPTION IS EXCESSIVE. I HAVE REPETITIVE CODES: P0089, P0300, P0366, P228D, P0014 AND THE CHECK ENGINE LIGHT BEING ON. CAR IS JERKING BACK AND FORTH WHEN AT A STOP LIGHT. TAPPING NOISE MADE ALSO. EVERY 1000-1500 MY CAR IS ALWAYS NEEDING OIL (AT LEAST 2 QUARTS) AND I ALSO HAVE TO PUT MORE THAN THE USUAL AMOUNT OF GAS IN IT THEN WHEN I FIRST PURCHASED.

EXPLODING SUNROOF.:DRIVING DOWN THE FREEWAY AND THE SUNROOF JUST BROKE OUT WITH A BIG HOLE IN IT.

STABILITRAK FLASH'S AND EVERYTHING ELECTRIC IN THE VEHICLE STARTS FLICKERING

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.

WHEN I HAVE MY ECO LIGHT AT STOPPING OR SITTING IT WILL CAUSE THE VEHICLE TO SHAKE OR LIKE IT STALL OR WANTS TO CUT OFF CUT OFF. WHEN THE ECO IS TURNED I DON'T HAVE THAT PROBLEM. THE ENGINE IS NOTOWN WHAT IS THIS PROBLEM? THIS HAPPENS ON STREET NOT THE HIGHWAY ON WHEN SITTING AT A STOP.

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..

JANURARY 7TH 2018 MY 2012 GMC TERRAIN RAN OUT OF OIL EVEN THOUGH IT WAS ALREADY FIXED 6 MONTHS PRIOR FOR SPECIAL ADJUSTMENT COVERAGE 16118 WHICH HAD PISTONS, PISTON RINGS, TIMING CHAIN ETC. FIXED TO REPAIR THE OIL CONSUMPTION ISSUE (SEE ADJUSTMENTS 14882 AND 16118. COVERAGE 14882 IS A RESULT OF FAILURE TO CORRECTLY FIX THE 16118 AND IS A DIRECT RESULT OF 14882 AND GMC STATES THEY WILL COVER ME IF THIS HAPPENS. GMC CUSTOMER SERVICE SAYS MY VIN # IS NOT COVERED UNDER THIS COVERAGE. IF ITS THE SAME EXACT ISSUE FOR (MODEL/ENGINE) WHY WOULD VIN # MATTER? ON TOP OF THAT I TOOK MY VEHICLE TO ANOTHER DEALER (DEALERSHIP B) AS I BROUGHT MY VEHICLE TO LETS CALL IT DEALERSHIP A SO MANY TIMES BEFORE WITH THE SAME ISSUE. DEALERSHIP B FILLED IT WITH OIL AND SENT ME ON MY WAY. I TOLD THEM TO MAKE SURE...

I PARKED MY VEHICLE IN THE DRIVEWAY. UPON EXITING THE VEHICLE I USED THE KEY FOB TO LOCK THE VEHICLE, IT BEEPED AND BEGAN TO WALK AWAY. AS I WAS ABOUT 10 STEPS FROM THE VEHICLE, IT BEEPED AGAIN AS IF I HIT THE FOB AND RESTARTED ITSELF. IT LITERALLY RESTARTED ITSELF. THEY KEYS WERE NOT IN THE IGNITION, THEY WERE IN MY HAND. I WAS UNABLE TO UNLOCK THE VEHICLE USING THE KEY FOB AND HAD TO MANUALLY OPEN THE DOOR USING THE ACTUAL KEY IN THE DOOR LOCK. I WAS UNABLE TO TURN THE VEHICLE OFF BY REINSERTING THE KEY IN THE IGNITION. I WIGGLED THE SHIFTER AND THE CAR TURNED OFF. THIS IS THE FOURTH THE CAR HAS BEEN RUNNING WHILE THE KEYS WERE NOT IN THE IGNITION AND IT IS THE SECOND TIME THE VEHICLE RESTARTED ITSELF WITHOUT THE KEY BEING IN THE IGNITION. THIS IS...

09/08/18 I PUT THE VEHICLE IN PARK, TURNED THE IGNITION OFF, REMOVED THE KEY FROM THE IGNITION AND EXITED THE VEHICLE. I GOT SOME ITEMS FROM MY TRUNK AND WENT ABOUT MY BUSINESS. ABOUT 45 MINUTES LATER, I RETURNED TO MY VEHICLE ONLY TO NOTICE THE LIGHTS WERE ON AND IT WAS RUNNING. I WAS UNABLE TO UNLOCK THE VEHICLE USING THE KEY FOB AND HAD TO MANUALLY UNLOCK THE DOOR. I PUT THE KEY IN THE IGNITION TO TURN THE VEHICLE OFF AGAIN AND IT WOULD NOT TURN OFF. I WIGGLED THE GEAR SHIFT AND IT FINALLY TURNED OFF. THIS IS THE SECOND TIME THIS HAS HAPPENED. PLEASE ADD MY VEHICLE TO THE RECALL LIST AS THIS IS THE EXACT ISSUE THAT THE OTHER GMC TERRAIN 2012 ARE HAVING.

I PUT THE VEHICLE IN PARK, TURNED THE IGNITION OFF, REMOVED THE KEY FROM THE IGNITION AND EXITED THE VEHICLE. I GOT SOME ITEMS FROM MY TRUNK AND WENT ABOUT MY BUSINESS. I RETURNED TO MY VEHICLE A FEW MINUTES LATER ONLY TO NOTICE THE LIGHTS WERE ON AND IT WAS RUNNING. I WAS UNABLE TO UNLOCK THE VEHICLE USING THE KEY FOB AND HAD TO MANUALLY UNLOCK THE DOOR. I PUT THE KEY IN THE IGNITION TO TURN THE VEHICLE OFF AGAIN AND IT WOULD NOT TURN OFF. I WIGGLED THE GEAR SHIFT AND IT FINALLY TURNED OFF. THIS IS THE THIRD TIME THIS HAS HAPPENED. PLEASE ADD MY VEHICLE TO THE RECALL LIST BEFORE SOMEONE GETS INJURED OR BEFORE THERE IS PROPERTY DAMAGE.

I TURNED OFF THE IGNITION TO MY 2012 GMC TERRAIN, REMOVED THE KEY AND OPENED THE TRUNK/HATCH TO RETRIEVE SOME ITEMS. AS I ATTEMPTED TO LOCK THE VEHICLE I REALIZED IT WAS STILL RUNNING. I WAS UNABLE TO USE THE KEY FOB TO UNLOCK THE DOORS AND HAD TO OPEN THEM MANUALLY. IT TOOK TWO ATTEMPTS AT INSERTING THE KEY IN TO THE IGNITION AND TURNING IT "OFF" BEFORE THE VEHICLE ACTUALLY TURNED OFF. THIS IS AN ISSUE WITH THIS VEHICLE YET ACCORDING TO THE DEALERSHIP "NOT WITH MY SPECIFIC VEHICLE" AND THEY WON'T EVEN LOOK AT IT WITH. PLEASE INCLUDE MY SPECIFIC VEHICLE IN THIS RECALL THAT WAS MADE ON 07/05/2016 STATING "GENERAL MOTORS LLC (GM) IS RECALLING CERTAIN MODEL YEAR...AS THE ELECTRONIC PARK LOCK LEVER MAY ALLOW THE IGNITION KEY TO BE REMOVED WITHOUT THE TRANSMISSION BEING IN PARK. ALSO, CERTAIN...2011-2013 GMC TERRAIN VEHICLES MAY HAVE BEEN SERVICED...

CHECK ENGINE LIGHT KEEPS COMING ON AND THE CODE COMING UP IS FOR THE CAMSHAFT PISTION. I HAD IT REPLACES AND WHEN I RUN MY AC FOR MORE THAN AN HOUR IN PARK, THE CHECK ENGINE LIGHT WILL COME ON AND THE TRUCK WILL DIE, OR THE TRUCK WILL DIE AND THE CHECK ENGINE LIGHT WILL NOT COME ON. THE TRUCK IS ALSO MAKING A LOUD RUMBLING NOSE.

2012 GMS TERRAIN 4 CYLINDER FLEX FUEL- CAMSHAFT CODE, CAM SENSORS REPLACED, SPITTING AND SPUTTERING, STALLED X3 AND SHUT OFF, FUEL CONSUMPTION NOTED, LOSS OF POWER. GMC DEALERSHIP REFUSED TO PERFORM DIAGNOSIS ON MY CAR DUE TO MY REFUSAL TO PAY FOR RULING OUT THE DOCUMENTED FUEL LEAK RECALL/SPECIAL COVERAGE. MY REQUEST WAS ONLY TO HAVE FUEL THE ISSUE LOOKED AT AND RULED OUT, NOTHING FURTHER, TO ENSURE THIS WAS NOT CAUSING MY PROBLEM. I REPORTED MY PROBLEMS THAT ARE CONSISTENT WITH THE NOTED FUEL SPECIAL COVERAGE AND TURNED AWAY BECAUSE I DID NOT HAVE $120 TO PAY IF THEY FOUND IT WAS NOT THE PROBLEM. UPON READING MY ISSUE CORRELATES WITH NUMEROUS TERRAIN AND EQUINOX OWNERS. I WANT IN THIS ACTION TO GET SOMETHING DONE FOR PEOPLE LIKE MYSELF.

WHEN I FIRST PURCHASED THIS SUV, IT WAS FINE. THEN TWO YEARS INTO HAVING THIS VEHICLE I HAD TO KEEP PUTTING OIL INTO IT. IT TURNS OUT THAT THIS YEAR CAR HAS AN OIL COMSUPTION RECALL. HOWEVER, I HAD TO GO IN FOR A TEST, I ALMOST RAN OUT OF OIL WITHIN A WEEK MY CAR WOULD STALL ON THE HIGHWAY, I WAS ALSO REAR ENDED BECAUSE IT WOULD OUT OF OIL WHEN IT WASN'T SUPPOSE TO. IN DEC 2017 I TOOK THE CAR IN AND GOT THE CAR RECALL DONE WHICH WAS NO CHARGE TO ME. HOWEVER, TWO DAYS AFTER THE RECALL WAS DONE MY CHECK ENGINE LIGHT CAME ON AGAIN. I TOOK IT BACK TO THE DEALERSHIP WHICH IS CAPPELLINO BUICK GMC IN WILLIAMSVILLE AND THEY CHARGED ME THE 119 TO DIANOGSIS THE CAR AND TELL ME THAT IT WAS THE CATALYTIC CONVERTER. HE TOLD ME THAT THE...

VEHICLE CHECK ENGINE LIGHT CAME ON AT 50,000 MILES, WOULD NOT PASS INSPECTION. COMPUTER DID NOT SHOW WHAT PROBLEM WAS. CAR WOULD CUT OFF IN DRIVE IN IDLE. CAR WOULD SHAKE. MECHANICS PUT IN NEW PARTS AND BATTERY FOR MORE THAN $1200. STILL WAS NOT FIXED. MECHANIC WENT TO A DEALERSHIP TO INQUIRE IF THEY HAD SEEN THIS PROBLEM. AT THE DEALERSHIP IT WAS DISCOVERED THAT MANY OF THE PARTS THAT WOULD CAUSE THE PROBLEM WERE ON RECALL. GM HAD NOT POSTED THESE RECALLS OR NOTIFIED ME, THE OWNER. AFTER INSPECTING THE CAR THEY SAID THERE WAS TOO MUCH WRONG TO REPAIR AND THE ENTIRE ENGINE WOULD NEED TO BE REPLACED. THEY SAID I WOULD NEED TO DRIVE 2000 MILES TO CHECK OIL CONSUMPTION. THEY NEVER MADE US AWARE THERE MAY BE PROBLEM WITH THE OIL CONSUMPTION. I AM 68 YRS OLD AND WALK WITH A WALKER. I AM IN...

WHILE DRIVING DURING HEAVY RAIN AT 50 MPH MY WINDSHIELD WIPERS STALLED RIGHT IN FRONT OF MY VIEW. THE MOTOR WAS OBVIOUSLY STILL FUNCTIONING BECAUSE I COULD HEAR IT BUT WIPERS WERE NOT MOVING. HAD TO PULL OVER TO KEEP FROM BEING INVOLVED IN ACCIDENT DUE TO OBSTRUCTED VIEW AND RAIN ON WINDSHIELD...THIS NEEDS TO RECALLED!! SAFETY ISSUE AND A HAZARD TO BOTH DRIVER AND OTHER VEHICLES ON ROAD. CALLED BOTH DEALERSHIP AND GMC DIRECTLY WHICK BOTH STATED DUE TO NO SET RECALL IT WOULD HAVE TO BE ON ME TO REPLACE AND PAY OUT OF POCKET FOR DIAGNOSIS OF VEHICLE AND THEN REACEMENT IF NEEDED! THIS 2012 TERRAIN ONLY HAS 65,900 MILES. THEY NEED TO GET IT TOGETHER BEFORE THEY END UP SUED FOR CAUSING ACCIDENTS OR DEATHS!

I RECENTLY RECEIVED A LETTER FROM GMC INFORMING ME THAT VEHICLES WERE BUILT INCORRECTLY, THAT THE FUEL COMPOSITION SENSOR MAY BE MOUNTED BELOW THE FRAME, EXPOSING THE SENSOR AND FUEL LINES TO ROAD DEBRIS, WHICH MAY RESULT IN THE FUEL LINE EMITTING FUEL ODOR, WEEPING, OR LEAKING. IN ADDITION, THE VEHICLE MAY EXPERIENCE ENGINE STUMBLE, LOSS OF POWER AND STALL WHILE DRIVING. IT DID NOT PROVIDE A PICTURE OF THE FUEL COMPOSITION SENSOR, NOR DID IT PROVIDE INFORMATION AS TO WHERE IT IS LOCATED. I WAS TOLD BY THE CUSTOMER ASSISTANCE CENTER THIS WAS INTENTIONAL. I AM NOW FEARFUL EVERY TIME I DRIVE THE CAR, BUT THIS IS MY ONLY MEANS OF TRANSPORTATION. I AM HIGHLY CONCERNED REGARDING NOT ONLY THE FAILURE OF THE FUEL COMPOSITION SENSOR AND FUEL LINES, BUT ROAD DEBRIS, OR AN ACCIDENT MAY PUNCTURE THE FUEL COMPOSITION SENSOR AND/OR FUEL LINES, CAUSING A POSSIBLE FUEL LEAK...

MY COMPLAINT IS IN REGARDS TO TIRES. SPECIFICALLY MICHELIN LATITUDE TOUR. MY TERRAIN IS 5 YEARS OLD WITH 27K MILES ON IT, NOT EXACTLY A LOT OF USE. HOWEVER I JUST FOUND OUT THAT THE TIRES ON THE VEHICLE, NOT THE ORIGINAL TIRES ARE FALLING APART. THE TREAD IS SEPARATING FROM THE TIRE BODY. AND THE TIRES ARE DRY ROTTED. IF YOU MEASURE THE TREAD DEPTH, THESE ARE ALMOST NEW TIRES. I AM AGHAST THAT AN EXPENSIVE TIRE LIKE THESE SHOULD JUST FALL APART. MICHELIN HAS GIVEN ME A RUN AROUND. THE TIRE TECH AT COSTCO TOLD ME THIS WAS A COMMON PROBLEM WITH THIS MODEL TIRE. HOW IN GOOD CONSCIENCE CAN A COMPANY LIKE MICHELIN CONTINUE TO SELL A DEFECTIVE DESIGN? CAN ANYTHING BE DONE TO MAKE THE PUBLIC SAFE?

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

I WAS PUTTING A PACKAGE IN THE REAR COMPARTMENT, WHEN THE HATCH STARTED TO CLOSE, IT HIT MY HEAD AND DIDNOT STOP, I HAD TO GRAP THE HATCH,AND HOLD IT UP..THERE IS SOMETHING TERRIBLY WRONG WITH IT.

CAR CRASH AT 45 MPH. FRONT IN DAMAGE AND AIR BAG DID NOT DEPLOY. SEATBELTS DID NOT LOCK UP.
