2009 GMC Acadia Engine Problems

There was a recall for gmc premature timing chain engine recall. This recall was complete in 2011 but it did not fix the problem. The timing chain keeps breaking off the cam shaft sensor and needs to be replaced.

Got code po0008 crank sensor/cam did resurch said timming chain replaced complete chain still noisey changed cam phasers and sensors still making noise it is so frustrating bee going on 3 weeks I'm disabled not easy to work on myself being I'm a master technician and this has really been mind boggling

The contact owns a 2009 GMC Acadia. The contact stated that after purchase of the vehicle, the vehicle lost motive power and stalled while driving at 45 MPH. There was no warning light illuminated. Despite the failure, the contact was able to coast the vehicle to a stop as the vehicle failed to restart after multiple attempts. The contact's husband inspected the engine and had the vehicle towed to the residence. The contact's husband replaced the crank shaft position sensor, purge valve, high pressure tank, fuel pump, and battery; however, the failure persisted. The contact then towed the vehicle to an independent mechanic where it diagnosed with engine failure due to the timing chain, and a cylinder #1 and #5 defect. The manufacturer was notified of the failure and informed the contact that there were no recalls on the vehicle related to the engine. The vehicle remained in possession of the mechanic unrepaired. The failure mileage was 194,726.

Engine jumped out of time driving down the road

CHECK ENGINE LIGHT CAME ON AND ENGINE LOST POWER DURING RUSH HOUR COMING HOME. LOST AT LEAST 50% POWER, VERY LITTLE ACCELERATION AND QUITE THE CHALLENGE TO MERGE OVER 4 LANES TO GET TO THE SHOLDER OF THE HIGHWAY. CODE WAS CHECKED AND CODE WAS FOR TIMING. MECHANIC PULLED TIMING CHAIN COVER AND FOUND THAT IT WAS STRETCHED. HE TOLD ME THE 3.6 ENGINE WAS WELL KNOWN FOR THIS. TWO FREAKING MONTHS AFTER WE PAID IT OFF. WILL NOT PURCHASE ANOTHER ACADIA AND WILL STAY AWAY FROM ENCAVE AND TRAVERSE AS WELL AS THEY HAVE SAME ENGINE IN MANY. VERY DISCOURAGED THEY WOULD KNOWINGLY ALLOW THIS ISSUE TO GO ON WITHOUT BEING ADDRESSED.

MY 09 ACADIA IS HAVING TIMING CHAIN ISSUES. JUST ABOUT EVERYONE OF THEM DOES. WHY IS THIS NOT RECALLED?

TL* THE CONTACT OWNED A 2009 GMC ACADIA. THE CONTACT TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC TO HAVE THE TIMING CHAIN REPLACED. WHILE THE MECHANIC WAS TEST DRIVING THE VEHICLE AT 30 MPH, THE VEHICLE BEGAN TO SMOKE. THE MECHANIC PULLED THE VEHICLE OVER AND DETERMINED THAT THE VEHICLE "BLEW UP". THE VEHICLE WAS DESTROYED. A FIRE AND A POLICE REPORT WERE FILED. THERE WERE NO INJURIES. THE VEHICLE REMAINED AT THE SCENE OF THE INCIDENT. THE MANUFACTURER AND DEALER WERE NOT NOTIFIED OF THE FAILURE. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE FAILURE MILEAGE AND VIN WERE UNKNOWN.

TL* THE CONTACT OWNS A 2009 GMC ACADIA. WHILE DRIVING 70 MPH, THE VEHICLE EXPERIENCED A LOSS OF ACCELERATION AND POWER. THE CONTACT VEERED TO THE SHOULDER OF THE ROAD AND ATTEMPTED TO RESTART THE VEHICLE. THE VEHICLE FAILED TO RESTART AND ALL THE WARNING INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE TIMING CHAIN FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE RECURRED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 138,000.

BOUGHT THE CAR ON FEB. 28, 2018. FOUND OUT ON JANUARY 23, 2019 THAT IT NEEDS A NEW ENGINE. THIS IS NOW THE 2ND GMC ACADIA WE BOUGHT IN LESS THAN TWO YEARS THAT NEEDS A NEW ENGINE. THAT IS NOT RIGHT. WE HAVE NOW SPENT OVER $20K FOR TWO CARS WE CURRENTLY DON'T HAVE A WORKING CAR. THE LAST CAR I BOUGHT WAS A 2010 GMC AND I WAS DRIVING THE CAR ON THE HIGHWAY AND SMOKE STARTED COMING OUT OF THE ENGINE. LATER IT WAS DETERMINED THAT THE ENGINED DIED - THERE WAS NEVER EVER WARNING LIGHTS OR WARNING THAT THERE WAS TROUBLE WITH THE CAR. BOTH CARS HAVE THE 3.6L SIDI VG ENGINE. OUR AUTO PLACE SAID THEY ARE HAVING A HARD TIME FINDING THAT ENGINE BECAUSE MANY PEOPLE NEED THAT ENGINE FOR THE EXACT SAME PROBLEM. CAN NOT BE A COINCIDENCE. I HAVE CONTACTED GMC AND THEY DON'T CARE.

SERVICE ENGINE SOON LIGHT COMES AND GOES, TOOK TO MECHANIC AND DIAGNOSED WITH P0017 CODE. CAM SHAFT PROBLEM, MECHANIC PUT NEW PART ON AND SERVICE LIGHT CAME BACK ON. THE PROBLEM NOW IS TIMING CHAIN AND THEN GET A NEW ENGINE ON A CAR THAT HAS APPROX 140,000 MILES. THE CAR EXPERIENCES A JITTER WHILE DRIVING AND WON'T ACCELERATE OR LAGS WHEN GAS PEDAL IS PUSHED.

P0017 AND P0008 ERROR CODES: MY WIFE LOVES HER ACADIA! DEALERSHIP HAS DONE RECALLS, REPLACED RACK AND PINION AND PS PUMP. I AM CLOSE TO POSITIVE THAT ECM HAS BEEN MODIFIED TO SHORTEN OIL CHANGE, TO NOT DEFINE A CHAIN POTENTIAL FAILURE THAT SENDS AN ERROR CODE, AND UPDATE SOFTWARE TO ALLOW FOR MORE "SLOP" IN CLEARANCE SPECS SO THAT CHAIN ISSUES ARE CONCEALED UNTIL A CRITICAL FAILURE OF EQUIPMENT. AT 121K I DROPPED CRADLE DOWN TO REPAIR/REPLACE WAVE PLATE. PLATE WAS GOOD AS NEW. MUST HAVE GOTTEN A "GOOD" PLATE. NOW AT ABOUT 140K I HAVE THE P0017 AND P0008 CODES. ENGINE NOT RESPONDING ACCELERATOR WISE AS BEFORE. I AM GOING BACK TO DEALER AND ASK TO SEE SERVICE RECORD OF WHAT WAS DONE TO ENGINE. I KNOW I WILL JUST BE WASTING MY TIME. TO COVER UP A PROBLEM BY MESSING WITH PARAMETERS ON AN ENGINE TO FOOL A CUSTOMER IS CLOSE TO BEING DISHONEST, AND THAT IS WHAT'S HAPPENING WITH THE CHAINS. IF ALL ELSE FAILS AT THE DEALERSHIP, AND THEY SEND ME AWAY, I WILL PARK THE ACADIA IN THE GARAGE AND DO MY BEST TO REPLACE THE CHAINS AND GEARS WITH THE ENGINE IN VEHICLE. I HAVE NO WAY TO DROP THE ENGINE OUT. I CAN'T AFFORD $4000 FOR THE DEALERSHIP TO DO IT. GM, I HAVE ALWAYS BEEN A LOYAL FAN ON YOUR VEHICLES, AND HAVE ONLY OWNED CHEVY'S AND GMC'S SINCE 1965, NEVER OWNED ANY OTHER BRAND, EXCEPT A 1947 JEEP UNIVERSAL THAT I PUT A SMALL BLOCK IN, BUT THIS ACADIA TRANSMISSION/ENGINE ISSUE MIGHT JUST TEST OUR RELATIONSHIP IN THE FUTURE. WHAT I HAVE READ ON SOCIAL MEDIA, THESE CODES ARE POPPING UP ALL OVER THE PLACE, AND GM IS NOT CARING, EVEN THO THEY NOW HAVE A 10 YR/120,000 COVERAGE. I AM BEGINNING TO THINK THAT THIS ISSUE WILL NEVER BE RESOLVED IN FAVOR OF THE CUSTOMER. DESIGN PROBLEM AND POOR BACK VALVE COVER VENTING. GM, YOU CAN DO THE RIGHT THING HERE.

TL* THE CONTACT OWNS A 2009 GMC ACADIA. WHILE DRIVING 55 MPH, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED AND THE VEHICLE MISFIRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THERE WAS FLUID INSIDE THE ENGINE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 151,000.

CAM ACTUATOR WENT BAD MAKES THE CAR SOUND LIKE A TRACTOR STARTS UP VERY LOUD AND MOTOR SOUNDS HORRIBLE ENGINE MAKES EXHAUST PIPES VERY LOUD. VERY LOUD ENGINE PERIOD.

TOOK VEHICLE TO LOCAL GMC DEALER FOR CHECK ENGINE LIGHT, AT 159,879 MILES. DEALER SAYS TIMING CHAIN IS MAKING NOISE AND GOING BAD. ESTIMATED REPAIR COST, $3,600. NOISE IS HEARD WHEN ENGINE IS STARTED AND SUBSIDES A LITTLE WHEN DRIVING.

THE CAR BEGAN MISFIRING SHORTLY AFTER I PURCHASED IT. HAD IT REPAIRED. SPARK PLUGS AND FUEL INJECTOR CAPS REPLACED. IT'S BEEN LESS THAN 6 MONTHS AND AGAIN THE CHECK ENGINE LIGHT IS ON AND THE CAR WILL NOT SHIFT GEARS OR ACCELERATE. EXTREMELY DANGEROUS TO N THE EXPRESSWAY. I DRIVE MY CHILDREN IN THIS CAR! CAR THREATENS TO DIE WHEN ATTEMPTING TO ACCELERATE.

THE 3.6L ENGINES HAVE AN ISSUE WITH TIMING CHAINS GOING BAD, POSSIBLY BREAKING.

TL* THE CONTACT OWNS A 2009 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING AT ANY SPEED, THE VEHICLE STALLED AND THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS PUSHED OVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO THE DEALER. THE VEHICLE WAS DIAGNOSED THAT THE CATALYTIC CONVERTER HAD TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED ABOUT THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

I HAVE REPLACED TWO IGNITION COILS AND NOW HAVE A THIRD GOING OUT. WHEN THE CAR IS UNDER LOAD IT MISSES.

GMC KNOWS OF DEFECTIVE TIMING CHAINS IN THIS MAKE AND MODEL. THEY ADDRESSED SOME OF THESE ISSUES IN TSBS AND THE INFORMATION WAS KNOWN BY DEALERS BUT NEVER CONVEYED TO OWNERS THAT DID NOT RECEIVE A TSB. THE DEALERSHIP PERFORMED NUMEROUS OIL CHANGES, WHICH IF INCREASED IN FREQUENCY AND MORE CLOSELY MONITORED, COULD HAVE BEEN PART OF THE FIX, BUT THE DEALERSHIP NEVER INFORMED THE OWNER OF POTENTIAL CATASTROPHIC CONSEQUENCES OF NOT INCREASING OIL CHANGE FREQUENCY. ACCORDING TO DEALER, GM FORBIDS THEM FROM DISCLOSING SUCH INFORMATION. THESE ENGINES WERE ALSO EQUIPPED WITH A PRESSED ON CRANKSHAFT RELUCTOR THAT COULD SHIFT AND RESULT IN A TOTAL CRANKSHAFT REPLACEMENT. FAILURE OF ANY OF THESE VITAL ENGINE PARTS ALONE OR TOGETHER WHILE THE VEHICLE WAS IN MOTION COULD, I BELIEVE, CAUSE AN ENGINE SEIZURE WHICH COULD POTENTIALLY LEAD TO DEVASTATING CONSEQUENCES. NON DISCLOSURE BY DEALERS TO ALERT OWNERS WHO COULD THEN DIVEST THEMSELVES OF THESE VEHICLES BEFORE THE 120K DEADLINE SET BY GM IS DISHONEST AT BEST. NO TSBS RELATING TO THIS WERE RECEIVED BY OWNER. THERE IS NOW AN ENGINE WARNING LIGHT CONCERNING THE TIMING CHAIN AND POSSIBLE RELUCTOR BUT GM IS UNWILLING TO ASSIST WITH REPAIRS SINCE THE VEHICLE IS ABOUT 15K BEYOND THEIR ARBITRARY 120K DEADLINE.

I JUST ENTERED THE HIGHWAY WITH AN INCREASED SPEED OF 50 MPH WHEN THE DASHBOARD FLASHED..."ENGINE POWER REDUCED." MY CAR WAS ABOUT TO SHUT DOWN IN THE MIDDLE OF A VERY BUSY HIGHWAY. I MADE IT TO THE SIDE OF THE STRETCH WITH CARS ALMOST HITTING ME TO CALL A TOW TRUCK. THE CAR WAS TOWED TO GATEWAY BUICK GMC IN ST. LOUIS, MISSOURI WHERE THE SERVICE WORKER INFORMED ME THAT I NEEDED THE FOLLOWING: VALVE ELEMENT HEATER HOSE CAMSHAFT ACTUATOR THERMOSTAT MODE DOOR ACTIVATOR I THEN RECEIVED A CALL BACK THE NEXT DAY STATING THAT I NEEDED A NEW ENGINE. MY CAR IS UNDER TEN YEARS OLD.
