2014 GMC TERRAIN Engine Problems

THE ENGINE IS BURNING OIL. LOSING OIL QUICKLY AND NO LEAK. WIPER MOTOR SHOT. 90K MILES ON VEHICLE

For the last 6 months my vehicle has excessive oil consumption 1/4 to 1/2 quart of oil every week. When it starts up it sounds like a diesel engine. In 2019 it did the same using about a 1/2 quart every 3 weeks. We have kept an eye on it ever since as over time it has increased oil consumption and just recently found out this is a problem for many others as well. We have always kept the oil changed when due per mileage sticker and vehicle oil life indicator.

My GMC Terrain makes a clunking noise under the hood when I accelerate and go into a lower gear. Does it mostly going up hills but also even on flat road.

The contact owns a 2014 GMC Terrain. The contact stated while driving at various speeds, the vehicle hesitated while depressing the accelerator. The service engine warning light was illuminated. The contact had taken the vehicle to several independent mechanics and was informed that the catalytic converter needed to be replaced. The contact then took the vehicle to the dealer and it was confirmed that the catalytic converter was defective and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 140,000.

Car is burning oil excessively and the timing chain is loose putting the vehicle is reduced power mode. The timing chain was replaced at 40,000 miles and now it needs to be replaced again and the car only has 87,000 miles. I bought it with 70,000 miles on it. Someone needs to do a recall on these engines

THE TIMING CHAIN BROKE WHILE I WAS DRIVING.

THE ENGINE IS BURNING OIL. LOSING OIL QUICKLY AND NO LEAK.

TIMING CHAIN ACTUATORS DIAGNOSED PROBLEM BY DEALER . CAR HESITATING, STALLING OUT WHILE DRIVING.

DRIVING ONE DAY ON A BEGINNING WINTER MORNING CR HAD RAN PERFECTLY FINE AND UP-TO-DATE ON OIL CHANGES PREVIOUSLY OF SIX MONTHS OF BUYING IT THEN CAR STARTED TO AUTOMATICALLY SHUT ITSELF OFF EVERY TWO MINUTES WHEN DRIVING DOWN THE ROAD NOT KNOWING THAT THE FUEL FUMES ADMITTED FROM THE ENGINE DO NOT HAVE A LARGE ENOUGH OUTLET CAUSING MY MAIN OIL SEAL TO BURST AND BLOW MY INTAKE AND THERE IS NO GUARANTEE THAT THIS WILL NOT BE FIXED AFTER GETTING REPAIRED DUE TO NOT BEING ABLE TO MODIFY THE ORIGINAL DESIGN.

WHILE DRIVING ON THE INTERSTATE IN BELOW FREEZING WEATHER THE LOW OIL PRESSURE LIGHT ILLUMINATED DIRECTING ME TO STOP THE VEHICLE IMMEDIATELY. AFTER WAITING 2 HOURS IN FREEZING TEMPERATURES I WAS ABLE TO GET VEHICLE TOWED TO A MECHANIC AND THE REAR MAIN OIL SEAL HAD BLOW OUT DUE TO A BLOCKED PCV VALVE. THIS IS A KNOW ISSUE UP TO 2013 GMC TERRAINS AND MINE IS 2014. PICTURES FROM THE SPECIAL COVERAGE BULLETIN 14882 LOOKS LIKE IDENTICAL PART STILL USED IN THE 2014.

WHILE DRIVING ON HIGHWAY AT APPROXIMATELY 70 MPH, ON LOW TEMPERATURE DAY (~10*F), SMOKE BEGAN EMITTING FROM BOTTOM OF VEHICLE WITH PUNGENT SMELL. THE VEHICLE WAS IMMEDIATELY PULLED OVER AND SHUT OFF. THERE WAS OIL COVERING THE ENTIRE UNDERCARRIAGE. THE OIL WAS PRESENT SUBSTANTIALLY ON THE EXHAUST SYSTEM, ALLOWING FOR POTENTIAL OF FIRE IF VEHICLE CONTINUED DRIVING. THE REAR MAIN SEAL WAS LEAKING AND REQUIRED TO BE TOWED HOME THEN TO DEALER AT LATER DATE FOR REPAIR. THE REPAIR AND ASSOCIATED REMEDIES FOLLOWED TSB 19-NA-021 BUT WERE NOT WARRANTIED AS THE VEHICLE'S VIN DID NOT FALL UNDER THE ASSOCIATED BULLETIN'S GUIDELINES. ALL REPAIRS AND REMEDIES WERE IDENTICAL TO PREVIOUS REPORTED FAILURES OF ABOVE LISTED BULLETIN.

TL* THE CONTACT CALLED ON BEHALF OF HIS DAUGHTER WHO OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT WHILE HIS DAUGHTER WAS DRIVING 60 MPH, WITHOUT WARNING, THE REAR MAIN SEAL FRACTURED CAUSING OIL TO LEAK FROM THE VEHICLE. THE VEHICLE WAS TOWED TO THE RESIDENCE. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE CONTACT, A CERTIFIED MECHANIC, INSPECTED THE VEHICLE AND NOTICED THE OIL LEAKING FROM THE REAR MAIN SEAL. TOM DAVIS CHEVROLET BUICK (2831 N 16TH ST, PARSONS, KS 67357, (620) 860-0751) WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS INFORMED THAT THE VIN WAS NOT UNDER RECALL. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE HOWEVER, NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 106,000.

CAR IS EXPERIENCING OIL CONSUMPTION AT A HIGH RATE. I LOOKED INTO HIS AND I GUESS IS VERY COMMON. AND I GUESS GM WON'T DO ANYTHING ABOUT IT. WHAT DO I DO NOW? DO I JUNK IT AND TAKE A LOSS AS THE MOTOR IS NOW MAKING NOISE . THERE HAS GOT TO BE SOMETHING TO DO.

LEFT MY HOUSE ON A VERY COLD MORNING (BELOW 10 DEGREES) AND WHILE I WAS DRIVING AND MY ENGINE STARTED MAKING A VERY LOUD CLATTERING NOISE. LOW POWER MESSAGE DISPLAYED ON THE DASH AND SEVERAL LIGHTS DISPLAYED. NOTHING PRIOR TO THE NOISE. IMMEDIATELY PULLED IN AND PARKED MY VEHICLE. I HAD THE CODES RAN, CHECKED THE OIL AND IT HAD NONE! THE VEHICLE WAS CHECKED OUT AND THE PCV VALVE FAILED/FROZE CAUSING COMBUSTION IN THE ENGINE AND BLEW OUT THE REAR MAIN SEAL. ACCORDING TO SERVICE BULLETIN 14882 THIS WAS AN ISSUE ON THE 2010-2013 GMC TERRAINS AND 2010-2014 CHEVROLET EQUINOX (WHICH IS BASICALLY THE SAME THING) A RECALL WAS ISSUED. MY VEHICLE IS A 2014 (WHO'S TO SAY WHEN THE ENGINE WAS NOT BUILT IN 2013?) AND IT DOESN'T APPEAR THE ISSUE WAS FIXED ON THE 2014S WHICH IS GOING TO COST ME APPROXIMATELY $3000 TO FIX. WHEN THE...

DURING COLD TEMPERATURES (14 DEGREES) MY PCV VALVE FAILED TO WORK WHILE SITTING AT A READ LIGHT WHILE I WAS DRIVING HOME FROM WORK ON A CITY STREET RESULTING IN MY REAR MAIN SEAL BLOWING. THIS WAS AN ISSUE ON THE 2010-2013 GMC TERRAINS AND OTHER GM VEHICLES AS NOTED IN THE SERVICE BULLETIN 14882. MY CAR IS A 2014 AND CLEARLY THE ISSUE HAS NOT BEEN RESOLVED WHICH HAS COST ME NEARLY $3000 IN REPAIRS. LUCKILY I WAS CLOSE TO HOME BUT THIS ISSUE COULD'VE LEFT ME STRANDED IN BELOW FREEZING TEMPERATURES. THIS ISSUE ALSO CAUSED OIL TO LEAK EVERYWHERE AND COULD'VE RESULTED IN A FIRE. MY CAR WAS SMOKING AND SMELLED AS THOUGH SOMETHING WAS BURNING.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED WHILE DRIVING 35 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TOWED TO THE LOCAL DEALER ETTLESON BUICK GMC (6201 SOUTH LA GRANGE ROAD, HODGKINS, IL 60525, (708) 529-5871) WHERE IT WAS DIAGNOSED WITH NEEDING THE PVC VALVE TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD NOT BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 91,000. *LN*JB

I BOUGHT IT IN JUNE 2020. USED EXCESSIVE OIL. I KEPT ADDING OIL. I THOUGHT IT WAS AN OIL LEAK AND TOOK IT IN TO FIRESTONE TO GET FIX. AS I WAS ALMOST THERE THE ENGINE LIGHT CAME ON AND WAS MAKING A LOUD NOISE UNDER THE HOOD. FIRST WARNING OF ANYTHING WAS WRONG, NO OTHER LIGHTS SHOWED ON DASH INDICATING A PROBLEM. I WAS DRIVING WHEN THIS HAPPENED. FIRESTONE SAID REALLY BAD OIL LEAK THAT DAMAGED TIMING CHAIN AND LOWER ENGINE. THEY SAID I NEED TO REPLACE THE ENGINE. WHY DIDN'T I GET ANY WARNING LIGHTS INDICATING THERE WAS A PROBLEM BEFORE MY ENGINE WAS DAMAGED DUE TO EXCESSIVE OIL USAGE. I SEE THIS SAME ISSUE HAS HAPPENED TO OTHER OWNERS WITH THIS VEHICLE. I WAS DRIVING ON THE HIGHWAY AND COULD HAVE BEEN IN AN ACCIDENT.

RADIO STSYEM WENT OUT, WIPED BLADE MOTOR DEFECTIVE, CAM SHAFT SENSORS WENT OUT DUE TO OIL CONSUMPTION, SENSOR ACTUATOR WENT OUT DUE TO OIL CONSUMPTION, CAR WOULD DIE WHILE DRIVING BECAUSE OF OIL CONSUMPTION/CAM SHAFT ERROR, ENGINE IS CONSUMING TO MUCH OIL-PER ENGINE OIL STUDY DONE BY MY DEALERSHIP.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT WHILE HIS WIFE WAS DRIVING AT AN UNDISCLOSED SPEED, THE VEHICLE STALLED WITH THE CHECK ENGINE AND LOW OIL PRESSURE WARNING LIGHT ILLUMINATED. ADDITIONALLY, THERE WAS A MESSAGE FLASHING ON THE INSTRUMENT PANEL WITH A MESSAGE TO TURN OFF THE VEHICLE. THE DRIVER PULLED OVER AND TURNED OF THE VEHICLE. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE REAR MAIN SEAL WAS BLOWN DUE TO EXCESSIVE CRANKCASE PRESSURE. THERE WAS ALSO A MINIMAL AMOUNT OF OIL IN THE ENGINE. THE MECHANIC INFORMED THE CONTACT OF TSB: 14882 AND 19NA021. ROBERT BROGDEN BUICK GMC (1500 E. SANTA FE ST., OLATHE, KS 66061 (913)782-1500) WAS CONTACTED AND STATED THE VIN WAS NOT UNDER RECALL. THE CONTACT WAS INFORMED TO TOW THE VEHICLE TO BE DIAGNOSED. THE VEHICLE WAS REPAIRED AT AN...

DRIVING FROM WORK CAR WAS WORKING FINE. CAME TO A STOP. CAR STARTED SOUNDING LIKE A DIESEL TRUCK. NEXT STOP CAR STOPPED ALL OF A SUDDEN. TOWED IT HOME THEN TO THE SHOP. MECHANIC ASKED ME WHEN I DID THE LAST OIL CHANGE. OIL CHANGE WAS DONE AT DEALERSHIP 8 WEEKS AGO. OIL HAD BURNED COMPLETELY AND CAUSED THE ENGINE TO FAIL. I NOW NEED TO REPLACE COMPLETELY. $5K ON A 6 YEAR OLD CAR WITH 84K MILES.

. IN OCTOBER 2019 MY CAR NEEDED TO HAVE EXTENSIVE WORK DONE ON ITS TIMING CHAINS, VARIABLE VALVE TIMING SOLENOIDS, INTAKE VARIABLE ENGINE VARIABLE TIMING SOLENOID, VARIABLE VALVE TIMING SPROCKET, HEATED OXYGEN SENSOR, TIMING COVER GASKET SET, VALVE COVER GASKET SET, IRIDIUM SPARK PLUGS, WATER PUMP, ENGINE OIL FILTERS, SYNTHETIC DEXOS MOTOR OIL, COOLANT. THEN IN JULY 2020 THE TIMING CHAINS COLLAPSED ON ME WHILE I WAS ON MY WAY HOME FROM WORK. THE ENTIRE ENGINE HAD TO BE REPLACED. MY CAR WAS COMPLETELY TOTALED AFTER THE ENGINE COLLAPSED AND I WAS STUCK OWING 12000 DOLLARS ON A USELESS CAR.

OWN 2014 GMC TERRAIN WITH 56K MILES ON IT, HAVE HAD THE CAR TWO YEARS AND HAVE HAD MULTIPLE ISSUES. FIRST INCIDENT, WAS DRIVING ON HIGHWAY IN RAIN WIPERS JUST SHIFT OFF. ALMOST WRECKED TRYING PULL OFF SIDE OF THE ROAD. COST $300 FOR NEW MOTOR. 2ND ISSUE HAD TO HAVE A SENSOR REPLACED BECAUSE CAR BURNED EXCESSIVE OIL IN BETWEEN OIL CHANGES, WITH NO INDICATION OF LOW OIL. FRIED THE SENSOR. 3RD ISSUE, A REPEAT OF THE 2ND CAR WOULD NOT PICK UP SPEED ON HIGHWAY, STABILTRAK LIGHT CAME ON, ENGINE LIGHT CAME ON, SPEEDOMETER STOPPED IMMEDIATELY, I CHECKED OIL. WASN'T BONE DRY. DROVE IT STRAIGHT HOME AND WAS IN EVEN WORSE CONDITION REVERSING INTO DRIVEWAY. THE OIL EXPLODED ALL OVER DRIVEWAY, HAD IT TOWED TO PRIVATE MECHANIC. NOW I HAVE TO PUT A WHOLE NEW ENGINE IN BECAUSE GM IS NEGLIGENT WITH ISSUING RECALLS. OIL WAS LEAKING FROM...

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED WHILE DRIVING 20 MPH, WHEN SHE STARTED TO HEAR AN ABNORMAL NOISE. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE CONTACT ALSO STATED THAT WHILE STATIONARY AT A TRAFFIC LIGHT, THE VEHICLE BEGAN TO STALL. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND WAS INFORMED THE TIMING CHAIN NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED AS OF YET. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED AS OF YET. A DEALER WAS NOT CONTACTED. THE MANUFACTURER HAD BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 45,000. THE VIN WAS NOT AVAILABLE.

MY 2014 TERRAIN 2.4 ECO TECH IS USING EXCESSIVE OIL CONSUMPTION. I NOTICED THERE HAS BEEN A RECALL AND CLASS ACTION SUIT ABOUT THIS. THIS HAS ALSO CAUSED MY TIMING CHAIN TO NEED REPLACED. I WAS DRIVING TO WORK A COUPLE WEEKS AGO AND THE ENGINE ENTERING LOW POWER MODE NOTIFICATION CAME ON. ALONG WITH THE CHECK ENGINE LIGHT. AND THE STABILITY CONTROL LIGHT CAME ON.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT THE VEHICLE CONSUMED AN EXCESSIVE AMOUNT OF ENGINE OIL. THE CONTACT STATED THAT OIL HAD TO BE ADDED BETWEEN OIL CHANGES. THE EMISSIONS WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO TWIN CITY BUICK GMC (3046 ALCOA HWY, ALCOA, TN 37701(865) 970-2977) AND THE CAMSHAFT SENSOR WAS REPLACED HOWEVER, THE FAILURE RECURRED. ADDITIONALLY, THE TIMING BELT MALFUNCTION AND THE VEHICLE WAS TAKEN TO ANOTHER INDEPENDENT MECHANIC. THE TIMING BELT AND CAMSHAFT WERE REPLACED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 89,000.

CAMSHAFT ACTUATOR MALFUNCTION CAUSING VECHILE TO SHUT DOWN -VERY UNSAFE. HAVE BEEN TOLD BY DEALER THIS HAPPENS TO ALL GMC TERRAINS AND ONCE FIXED IT WILL HAPPEN AGAIN - SHOULD NOT HAVE TO PAY FOR SOMETHING THAT IS YOUR PROBLEM.

I WAS ON MY WAY TO WORK. ALL OF A SUDDEN MY CAR STOPPED ABRUPTLY, WITH NO WARNING LIGHTS OR SIGNALS. IMMEDIATELY AFTER THE CAR SHUT OFF, THE ENGINE LIGHT CAME ON. THE CAR WAS TOWED TO GMC. I WAS CONTACTED ON SATURDAY, AUGUST 30TH, BY THE SERVICE TECH FOR AN UPDATE. APPARENTLY, THE SPARK PLUG MOVED OUT OF PLACE, AND THE PISTON PUSHED IT INTO THE ENGINE. THE TECHNICIAN MENTIONED THAT HE HAD NEVER SEEN ANY LIKE THIS BEFORE. THE VEHICLE IS ONLY 6 YEARS OLD. THERE SHOULD BE NO WAY THAT SOMETHING LIKE THIS COULD TAKE PLACE AND I LOSE EVERYTHING AND HAVE TO PURCHASE AN ENTIRE NEW ENGINE. MOREOVER, HAD I BEEN ON THE INTERSTATE WHEN THIS HAPPENED, I COULD HAVE BEEN KILLED ALONG WITH OTHER PEOPLE AS WELL. IN A WORLD OF TECHNOLOGY, THERE IS NO WAY THAT THIS SHOULD HAVE HAPPENED WITHOUT ANY WARNINGS OR...

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE SHUTOFF WITHOUT WARNING. THE CONTACT ATTEMPTED TO RESTART THE VEHICLE MULTIPLE TIMES BEFORE THE VEHICLE WOULD RESUME NORMAL OPERATION. NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE VEHICLE HAD YET TO BE REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 81,000.

VEHICLE WILL SPUTTER AND DIE WHEN SLOWING DOWN OR STOPPING. HAS HAPPENED ON FREEWAY AND NORMAL DRIVING. TOOK VEHICLE IN AND THEY LET ME KNOW THE TIMING CHAINS, PHASER AND SENSORS ARE NEEDED TO RESOLVE THE ISSUE. THE PROBLEM IS DUE TO THE ENGINE BURNING TOO MUCH OIL. VEHICLE WILL ALSO NOT PASS EMISSIONS TESTING.

I AM HAVING AN ISSUE WITH THE OIL IS BURNING AND IT IS CAUSING OTHER COMPONENTS TO GO BAD ON MY CAR LIKE THE CATALYTIC CONVERTER . AND IT IS BURNING OUT AND I HAVE TO CONTINUE TO PUT OIL IN THE CAR... I HAVE RESEARCH AND I SEE THAT ALL THESE MODELS IS HAVING ISSUES WITH THE BURNING OF THE OIL. *TR

DRIVING BETWEEN 40-45MGH AND STABILITRAK FAILURE SERVICE AND ABS FAILURE LIGHT COMES ON. AT EVERY BUMP THE SERVICE LIGHTS GOES ON AND OFF. THEN ON A SMOOTH SERVICE THE STABILITRAK LIGHTS COMES ON UNTIL I GET HOME. WITH THE COLLISION WARNING TURNED ON THE CAR ALSO AND ALMOST FREQUENTLY TENDS TO BRAKE ON ITS OWN WHILE DRIVING. BUT HERE'S THE REAL PROBLEM THIS 2014 GMC TERRAIN DENALI CAR IS NOT ON THE 'RECALL' LIST - WHY? SEEMS IT'S FROM THE SAME CAR MANUFACTURER WITH SAME ISSUES, SHOULDN'T IT BE ON THE SAME RECALL LIST.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT SOON AFTER RECEIVING AN OIL CHANGE, THE OIL WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE PCV VALVE WAS CLOGGED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, A RATTLING SOUND WAS PRESENT COMING FROM THE ENGINE. ADDITIONALLY, THE ENGINE OIL PRESSURE LOW WARNING LIGHT WAS ILLUMINATED. THE CONTACT INSPECTED THE VEHICLE AND BECAME AWARE OF AN OIL LEAK UNDERNEATH THE VEHICLE. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE REAR MAIN ENGINE SEAL WAS BLOWN AND THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE LOCAL DEALER AXELROD BUICK/GMC (6603 BROKE PARK RD, PALMER OH) AND THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 92,000.

ENGINE WILL NOT HOLD OIL. CAUSING ENGINE TO STALL AT ANY GIVEN MOMENT WHILE IN MOTION. VEHICLE HAS BEEN DIAGNOSED BY DEALER AND THIRD PARTY AUTO MECHANIC. BOTH HAVE DETERMINED PISTON + PISTON RINGS NEED REPLACED BUT A FULL ENGINE REPLACEMENT IS THE PREFERRED REPAIR. VEHICLE HAS LESS THAN 119,000 MILES. VEHICLES NOTIFICATION LIGHTS INCLUDE: CHECK ENGINE LIGHT, SERVICE STABILITY TRACK AND REDUCED ENGINE POWER.

MY 2014 TERRAIN STALLED OUT AT A STOP SIGN. I RESTARTED THE TRUCK AND WAS IT MADE A NOISE AS THOUGH SOMETHING WAS WRONG WITH A BELT. I WENT AROUND THE BLOCK AND IT STALLED OUT 3 MORE TIMES. I BACKED IT INTO MY DRIVEWAY AND NOTICED ALL OF THE OIL ON THE GROUND. I HAD THE TRUCK PUT ON A FLATBED AND TOWED TO THE DEALER. ACCORDING TO THE SERVICE DEPARTMENT, THE REAR MASTER SEAL BLEW. SOMEHOW, AS EXPLAINED TO ME, WATER GETS INTO THE ENGINE AND FREEZES. THIS CAUSES PRESSURE AND THAT IS THE CAUSE OF THE DAMAGE. MY TERRAIN TURNED 5 YRS OLD ON 11/21/19 WITH ONLY 50,249 MILES. I AM VERY DISAPPOINTED. I HAVE ALWAYS OWNED A GM VEHICLE AND HAVE NEVER HAD A PROBLEM UNTIL NOW. THE WARRANTY DOES NOT COVER SINCE IT IS 5 YRS OLD AND I AM OUT $3,000 FOR REPAIRS. I...

ENGINE STALLS/ HESITATES ESPECIALLY WHEN AT A STOP, IDLE FOR A PERIOD SUCH AS AT A STOP LIGHT, ALSO WHEN IN REVERSE AND DOES NOT HAVE A CHECK ENGINE LIGHT. THIS DID HAPPEN BEFORE AND A CHECK ENGINE LIGHT DID APPEAR. I PULLED THE CODES P0010 AND P0011.

I HAVE ONLY HAD THE VEHICLE SINCE 11/2019. IT TWICE HAS HAD THE CHECK ENGINE LIGHT TO COME ON. THE FIRST TIME IT WAS IN 12/2019. THE CHECK ENGINE LIGHT WAS ON FOR ABOUT A WEEK. THE AUTO START WAS NOT WORKING, AND THE ONLY ISSUE I SEEN WAS THAT IF IT SAT RUNNING FOR A WHILE LIKE FOR INSTANCES, WARMING UP, IT FLOODED AND THE ENGINE WOULD CONTINUE TO RUN A FEW SECONDS AFTER IGNITION KEY WAS TAKEN OUT OF THE IGNITION. ENGINE WOULD STOP AFTER BUBBLING TO A STOP. THEN THE CHECK LIGHT WENT OUT AND EVERYTHING WORKED PROPERLY. BUT, ON 2/1/2020, MY CHECK ENGINE LIGHT CAME ON AGAIN. MY AUTO START IS NOT WORKING AGAIN. AS LONG THE CHECK ENGINE LIGHT IS ON, THE VEHICLE WILL NOT AUTO START. THE CAR IS AGAIN FLOODING OUT AFTER ENGINE SHUT DOWN. AFTER IGNITION KEY IS TAKEN OUT OF IGNITION....

THE CAR AT 80K HAD ITS ENGINE REPAIRED UNDER WARRANTY FOR A BAD DEAL WHICH THEN RUINED PISTONS AND ETC. AT 155K IT DID THE SAME AND POWERED DOWN ON THE SIDE OF THE ROAD WITH ENGINE ISSUES. I WAS DRIVING ON THE ROAD WHEN THIS HAPPENED LEAVING ME ON A CURVE AND THE ENGINE FUMING AND OIL POURING OUT UNDER NEATH

THIS CAR BURNS 3 QUARTS OF OIL BETWEEN 5000 MILE OIL CHANGE INTERVALS. IT HAS DONE IT SINCE IT WAS NEW. I JUST FOUND OUT IT IS BECAUSE OF A FAULTY PCV SYSTEM.01

VEHICLE HAS 85000 MILES AND NEEDS NEW TIMING CHAIN DUE TO BURNING OIL. QUOTED $2200-$2800 FOR REPAIR. ROUGH RIDING, WANTS TO STALL AT LOWER SPEEDS, SLOW DOWNS AND STOPS. STILL OWE ON THIS VEHICLE, BOUGHT FROM DEALERSHIP NOT EVEN TWO YEARS AGO.

TL* THE CONTACT OWNS A 2014 GMC TERRAIN. THE CONTACT STATED THAT WHILE DRIVING AT 40 MPH, OIL PRESSURE WARNING LIGHT ILLUMINATED. THE CONTACT VEERED TO THE SHOULDER OF THE ROAD, GOT OUT THE VEHICLE AND DISCOVERED THE OIL FLOWING OUT THE ENGINE. AAA WAS CONTACTED AND TOWED THE VEHICLE TO THE DEALER REICHARD CHEVROLET: 575 ARLINGTON RD, BROOKVILLE, OH 45309(937) 833-4011 WHERE IT WAS DIAGNOSED THAT THE ENGINE MAIN SEAL FRACTURED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND MADE AWARE OF THE FAILURE INFORMED THE CONTACT THAT THE EXTENDED WARRANTIES EXPIRED BUT THEY WOULD OFFER $100 CERTIFICATION FOR REPAIRS. THE FAILURE MILEAGE WAS APPROXIMATELY 109,000.

I BEEN CHANGING MY OIL EVERY 2000 MILES HOWEVER ENGINE OIL STAYS LOW; SEVERAL SENSOR MALFUNCTIONED STATING THAT THE THROTTLE POSITION SENSOR, CAMSHAFT SENSOR, AND CRANKSHAFT SENSOR WAS BAD BUT IN FACT IT WAS THE ENGINE. WHILE AT THE REPAIR SHOP TO REPLACE THE CAMSHAFT SENSOR BECAUSE THE VEHICLE WOULDN'T START I LEARNED THAT THE ENGINE LOCKED AND HAD TO BE REPLACED THE ENGINE DUE TO LOW TO NO OIL IN THE ENGINE BUT IN FACT I GOT THE OIL CHANGE 2-3 MONTHS AGO

I HAVE A 2014 GMC TERRAIN WITH 102000 APPROXIMATELY. I RECEIVED NOTICE THAT I NEEDED TO CHANGE MY OIL. I WENT ABOUT 50 MILES AND STARTED MAKING A BUBBLY SOUND. WHEN I WENT TO GET MY OIL CHANGED, THE MECHANIC SAID IT WAS SO LONG THEY COULDN'T GET SOME ON THE DIP STICK. I LEFT THE MECHANIC WITH 100% OF OIL AND JUST DROVE TO SAN ANTONIO AND IT IS DOWN TO 98 %. I HAVE A 2008 CHEVY TRAILBLAZER AND HAVE NEVER HAD THIS PROBLEM.

THE PCV SYSTEM THERE'S PLUGGED UP DUMPING OIL INTO THE INTAKE AND TO THE THROTTLE BODY OILS IN THE INTAKE MANIFOLD CRANKCASE TOO MUCH PRESSURE

2014 GMC TERRAIN WITH 66,000 MILES STALLING OUT WHEN SLOWING/STOPPING, LOW ACCELERATION, LOUD ENGINE. DEALER SAYS OIL IS LOW WHEN IT WAS JUST REPLACED 2 MONTHS (2,700 MILES) AGO. CANNOT DETERMINE WHY VEHICLE IS CONSUMING MORE OIL THAN WHAT GM ALLOWS.

VEHICLE WITH ONLY 75,00 MILES, RUNS ROUGH AND STALLS, WENT TO DEALER AND THEY SAY DUE TO LOW OIL AT SOME POINT THE TIMING CHAIN HAS STRETCHED AND NEEDS REPLACED ALONG WITH SENSORS AND ACTUATORS. TIMING CHAIN AND ASSOCIATED PARTS REPLACED TO THE TUNE OF $1715.00. I CHECK THE OIL AND THE DEALERSHIP HAS BEEN CHANGING IT. THIS LOOKS TO BE A FACTORY DEFECT. I HAVE SENT A LETTER TO GM FOR RESOLUTION AS WELL.

MY CAR COMPLETELY SHUT DOWN WHILE TURNING A CORNER (POWERED OFF). I ALMOST HIT A TREE BECAUSE I WAS UNABLE TO TURN THE STEERING WHEEL. ONCE I APPLIED THE BRAKE AND PUT IT INTO PARK, I WAS ABLE TO RESTART IT WITH NO APPARENT ISSUE.

WAS DRIVING AN CAR CUT OFF AN WILL NOT START WAS DRIVING ON A CITY SREET

AS I WAS DRIVING HOME AFTER WORK THE CAR JUST STARTED MAKING A NOISE AND CUT OF AND DID NOT START HAD TO TOW TO A GMC DEALER THAT SAID IT NEED A NEW ENGINE I AS DRIVING ON THE CITY STREET

AROUND 90,000 MILES THE ENGINE BEGAN BURNING OIL. I HAD TO ADD OIL EVERY 2,000 MILES. AT 101,000 MILES RADIATOR FAILED. AT 123,000 MILES THE ENGINE COMPLETELY FAILED. THE MECHANICS AT GM DEALERSHIP COULD NOT EXPLAIN IT. THEY SAID IT APPEARED THAT THE ENGINE WAS BURNING OIL. I HAD TO SPEND $7,000 TO REPLACE ENGINE AND ADDITIONAL PARTS THAT WERE DAMAGED DUE TO THE ENGINE FAILURE. I HAVE SEEN MANY REPORTS ABOUT THE ENGINES FOR THIS MODEL AND YEAR BURNING OIL WITH NO ACTION OR RECALL FROM GM. ONCE MORE OWNERS HIT 100,000 MILES, I BELIEVE THAT THERE WILL BE MORE REPORTS OF THIS ENGINE ISSUE. HOPEFULLY GM WILL THEN RESPOND AND ISSUE A RECALL.
