2011 GMC TERRAIN Complaints

CURRENT KEY IS 10+ YEARS OLD. STEERING LOCKS UP SOMETIMES AND CANNOT START CAR. IT IS HELL TO UNLOCK STEERING. I ORDERED A NEW KEY BOB ABOUT 5 WEEKS AGO. GMC PARTS SAYS GM HAS NOT SNET NEW KEY BOB YET!!! SO, STEERING MAY LOCK UP AND WITH NO NEW KEY BOB CANNOT DRIVE CAR. SO, I'M SUPPOSE TO PUSH CAR???

CAR RANDOMLY SHUTS OFF WHILE DRIVING IT DOESN'T MATTER IF I AM ON THE HIGHWAY OR DRIVING THROUGH THE CITY, ALSO ENGINE POWER REDUCED MODE. THROWS RANDOM CODES EVEN AFTER CODES HAVE BEEN SERVICED. WE HAVE BEEN DEALING WITH THIS ISSUE FOR CLOSE TO 2 YEARS WITH NO RESOLVE. AFTER FURTHER INVESTIGATION WE HAVE FOUND THERE ARE MULTIPLE COMPLAINTS OF THIS EXACT ISSUE.

MY VEHICLE HAD BEEN HAVING TO COMMON OIL CONSUMPTION MEANING I CHECKED THE OIL EVERY TIME I GOT FUEL. THIS LAST TIME I WENT TO CHECK THE OIL LEVEL THE DIPSTICK WAS UNDER SO MUCH PRESSURE IT SHOT TWENTY FEET INTO THE AIR WHEN THE HOOD OPENED. I THEN DROVE THE VEHICLE FROM THE GAS STATION BACK HOME AND THIS TIME TOOK THE OIL FILL CAP OFF AND WHEN I TURNED THE CAP A QUARTER TURN IT BLEW OFF INTO THE AIR FOLLOWED BY BURNING HOT OIL DROPLETS AND STEAM. WHEN I RUN THE VEHICLE FOR ANY AMOUNT OF TIME THE OIL DRAIN BACK SYSTEM BUILDS MORE PRESSURE THEN THE COOLING SYSTEM EVENTUALLY CAUSING THE VEHICLE TO STALL UNDER LOAD SUCH AS WHEN TAKING OFF FROM A STOP. WHEN THE VEHICLE DOES STALL IT WILL TAKE FROM 2-10 MINUETS TO RESTART.

WHILE DRIVING ALONG WITH ONGOING TRAFFIC THE VEHICLE STOPS AND ALMOST CAUSED ME AN SEVERAL ACCIDENTS.

EXCESSIVE ENGINE OIL CONSUMPTION ABOUT A QUAKER OF OIL EVERY 2000 MILES. THIS VEHICLE WAS BOUGHT FROM A NON GMC AS USED CERTIFIED WITH 145450 MILES DATE 01/18/2019. BY THEN THEN VEHICLES WAS CLASSIFIED AS RECALL. WITH ESPECIAL COVERAGE WARRANTY FROM GMC PLEASE SEE BULLETIN NUMBER 15285A. I REACH OUT TO GM CUSTOMER ENGAGEMENT CENTER OF CA, BUT THEY REFUSED TO PAY FOR DIAGNOSES FEES AND REPAIRS , QUOTE THE VEHICLE IS OVER 120000. I HAD ALSO MADE A COMPLAIN TO THE BETTER BUSINESS BUREAU. I WOULD LIKE GMC PAY FOR DIAGNOSES AND REPAIRS TO A CERTIFIED LOCAL GMC DEALERSHIP. THANK YOU FOR YOU HELP RESPECTFULLY, CUSTOMER

ON A HIGHWAY WAY HOME AND SAYS REDUCED ENGINE POWER LIKE 3 DAYS AFTER GETTING TRANSMISSION REPLACED HAD TO GET IT TOWED I HAD MY KIDS WITH ME AND MECHANIC TOLD ME IT'S THE ENGINE IT HAD NO OIL IN IT WHEN IT DID HAVE OIL BEFORE THAT HAPPENED IT DIDN'T SHOW LEAKING OR NOTHING NOW I'M OUT OF MY MONEY UNDER 86,000 MILES YET 2011 TERRAIN

TL* THE CONTACT OWNS A 2011 GMC TERRAIN. THE CONTACT STATED THAT HER VEHICLE WOULD FAIL TO START UP AFTER MULTIPLE ATTEMPTS WITH AN UNKNOWN ENGINE WARNING LIGHT ILLUMINATED ON THE DASHBOARD. DUE TO THE FAILURE, THE CONTACT HAD THE VEHICLE TOWED TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DIAGNOSE THE FAILURE BUT STATED THAT THE FAILURE WAS LIKELY CAUSED BY A DEFECT INSIDE THE ENGINE. NEITHER THE DEALER NOR THE MANUFACTURER WERE NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 115,497.

PURCHASED A 2011 GMC TERRAIN IN MAY WITH 94K MILES. W?HEN CHANGE OIIL LIGHT CAME ON, TOOK TO A GMC DEALER TO HAVE IT SERVICED. DROVE IT HOME ABOUT 50 MILES, PARKED IN GARAGE AND 4 DAYS LATER STARTED IT. ENGINE MADE A WEIRD NOISE SO I TURNED IT OFF. WOULD NOT START AGAIN AND HAD IT TOWED TO A LOCAL GARAGE WHO TELLS ME THE TIMING CHAIN BROKE AND BENT ALL THE VALVE STEMS AND DAMAGED THE HEADS. THE VEHICLE IS FINANCED SO I'M MAKING PAYMENTS ON A WORTHLESS SUV THAT NOW NEEDS A NEW ENGINE AT A COST OF ABOUT 7500.00.

ON 08/05/2020 I WAS SOLD THIS VEHICLE WITH A CRACKED MANIFOLD. UPON REPLACEMENT OF THE MANIFOLD IT WAS DISCOVERED THAT TWO MANIFOLD BOLTS WERE SEARED ON THE ENGINE BLOCK SIDE. AFTER CONSULTING MY MECHANIC AND ANOTHER, I WAS ADVISED THAT 1) TO REPAIR THE ENGINE HAS TO BE LIFTED AS THE SPACE BETWEEN THE FIREWALL AND THE ENGINE IS TOO SMALL TO MAKE REPAIRS WITHOUT LIFTING THE ENGINE ( MANUFACTURE DEFECT) . FURTHER, IT WAS ADVISED TO ME THAT COMPLETELY SEALING THE MANIFOLD COULD LEAD TO A FIRE IN THE CATALYTIC CONVERTER BECAUSE ' THESE ENGINES RUN HOT'. AS I EXPRESSED THAT THIS VEHICLES 'ANTIFREEZE' LEVEL IS NOT STABLE AS I HAVE EXPERIENCED WITH OTHER VEHICLES. IN OTHER WORDS THIS VEHICLE BURNS UP ANTIFREEZE QUICKER THAN I'VE SEEN OCCUR IN OTHER VEHICLES. AFTER RESEARCHING THE TOPIC IT WAS DISCOVERED BY CONSUMER REPORTS THAT THESE VEHICLES HAVE MAJOR DEFECTIVE ENGINES WITH REPAIRS TO MANIFOLD BEING NOTORIOUS. AND TO HAVE TO HAVE THE ENGINE LIFTED EACH TIME IS UNREASONABLY COSTLY. AND I NO LONGER FEEL SAFE DRIVING THIS VEHICLE IF A DEFECTIVE ENGINE RUNS HOT AND THERE'S A RISK OF FIRE. THIS IS EXACERBATED BY THE FACT OF THE TINY SPACE BETWEEN THE ENGINE AND FIREWALL WITHIN THE VEHICLE.
