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 in 2018 that this was an issue or that it was "taken care of" if I had i wouldn't have paid over $20,000. into my car. Reading several complaints online about this exact issue is all new to me. Knowing i could have been driving a vehicle and it could have started a fire in my engine is crazy to think. Because I may have been driving a car with a serious recall on it. I am at a loss right now, financially i am screwed.

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 of the owners but the manufacturers & dealerships that knowingly sell these autos that can be dangerous.

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.

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.

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 THE ISSUE WAS FIXED. THEY SAID THEY TEST DROVE IT AND EVERYTHING IS FINE AND THEY DIDNT DO ANYTHING BUT PUT OIL IN IT AND TEST. ON THE WAY HOME JAN. 7TH THE SAME DAY THE CAR STARTING DYING ON ME, STALLING AND MAKING POPPING NOISES AND JERKING WILDLY WHICH IS WHY I BROUGHT IT IN THE FIRST PLACE. DEALERSHIP B KNOWING DEALERSHIP A "FIXED" THIS ISSUE 6 MONTHS BEFORE SO THEY SAID THEY WOULD NOT FIX IT EVEN THOUGH THEY KNOW FOR SURE THIS ISSUE WAS CAUSED BY COVERAGE 14882. I TOLD DEALERSHIP A THIS AND THEY SAID THEY ARE ONLY GOING WITH WHAT GMC SAYS WHICH IS THAT MY VIN # IS NOT COVERED BUT THEY WERE WILLING TO SPLIT THE COST WITH ME (ROUGHLY $850, ADMITTING PARTIAL FAULT, LOL) I SAID NO AND THEN PLEADED WITH THEM THAT I SHOULDNT PAY ANYTHING CAUSE IM COVERED. THEY ENDED THE CONVERSATION WITH THE VEHICLE IS NOT COVERED BECAUSE COVERAGE 16882 IS NOT RELATED IN ANY WAY TO 14882 BUT EVEN GMC AND DEALERSHIP B SAYS THEY ARE DIRECTLY RELATED. WHO IS LYING HERE? I PAY $450 A MONTH FOR A GIANT SUV THAT SITS IN MY GARAGE. GMC IS KNOWINGLY BREAKING THE LAW, HOW CAN THEY DO THIS TO SO MANY PEOPLE?

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 CLEARLY A MANUFACTURING ISSUE. WHAT ARE YOU WAITING FOR TO ADD THIS VEHICLE TO THE RECALL LIST? PROPERTY DAMAGE AND PERSONAL INJURY WILL EVENTUALLY OCCUR AND THEN I WILL SUE GMC FOR DAMAGES. I AM OFFICIALLY PUTTING GMC ON NOTICE. PLEASE RECALL THIS VEHICLE AND FIX THIS ISSUE.

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 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 WITH SIMILAR DEFECTIVE REPLACEMENT ELECTRONIC PARK LOCK LEVERS. AS SUCH, THESE VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD (FMVSS) NUMBER 114 "THEFT PROTECTION AND ROLLAWAY PREVENTION."

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 CATALYTIC CONVERTER WAS NOT COVERED ENOUGH THOUGH HE STATES THAT THEY KNOW THAT THE ENGINE CONSUMPTION RECALL MADE THE CATALYTIC CONVERTER GET CLOGGED. I HAVE CHANGED MY O2 SENSOR TWICE AND I WILL PROBABLY HAVE TO CHANGE IT AGAIN BECAUSE ONCE THE CATALYTIC CONVERTER GOES, TYPICALLY THE O2 SENSORS GO AS WELL. IF YOUR CAR IS CONSUMING A LOT OF OIL, BLOWING BLACK SMOKE AND IT IS A GMC TERRAIN (NO MATTER THE YEAR), GET IT CHECKED, HONESTLY, I AM NOT BEING OVERDRAMATIC, IT COULD BE LIFE OR DEATH. IF YOU HAVE KIDS AND YOU HAVE THE CAR, GO FOR A OIL CONSUMPTION TEST ASAP. MY CAR STALLED OUT ON THE HIGHWAY, STOP LIGHTS AND STOP SIGNS, EVEN WHEN NOT COMPLETELY STOPPED OR PERFORMING A "ROLLING STOP".
