2010 Buick Enclave engine problems

ENGINE

I am filing this safety complaint regarding a sudden and dangerous engine failure in a 2010 Buick Enclave CXL purchased from Frankfort Car Outlet on 8/25/2025. On 10/25/2025, while driving on the expressway, the engine suddenly began knocking, lost power, and stalled. This created a serious safety risk to myself and other drivers. The failure occurred only 60 days after purchase and approximately 2,000 miles later, suggesting a pre-existing internal defect that the dealership did not disclose. The dealership has refused to inspect the vehicle, acknowledge the safety risk, or assist in any way. This type of sudden engine failure could pose a serious hazard if similar vehicles have the same issue, and I believe NHTSA should be aware of the potential risk.

ENGINE

The engine and fuel pump system failed while driving the vehicle. It is available upon request to inspect. I just towed it to the shop today on 10/22/25 to get a full inspection. My sister and I were put at risk while driving towards a hill in San Francisco. It was on a busy main road when suddenly the vehicle began to jerk and thud back and forth. While I pushed the gas pedal, I began to question why the vehicle was suddenly reacting this way. In efforts to pull over to the side, a huge smoke fog began to come out of the exhaust pipe. As I tried to reach the curb the car didn’t want to move any further as I pushed on the gas. I put it in park and called the tow truck (receipts below) while there were cars passing me by almost causing an accident. I have looked online to see if there was a problem or recall with this vehicle having the same issue I was having. Come to find out there was a recall issued for certain vehicles only, with the same issue as my vehicle. The vehicle was taken into a local auto shop, where they diagnosed it and inspected it. The reports show it has the same exact issues with the car as those that were recalled. No there were not any warning signs nor failure signals. Due to this reason, I was completely caught off guard.

ENGINE

The engine was built with the same components as the 2008/2009 models and they have been recalled, the oil drains out of the engine rapidly and causes engine to seize and had to be replaced.

WHILE DRIVING DOWN THE ROAD, THE LOCKS ON THE DOORS WILL SUDDENLY LOCK, UNLOCK, LOCK AND UNLOCK. AFTER THAT THE ENGINE SLOWS WAY DOWN LOSING POWER, THEN IT WILL BE OKAY TO GIVE IT MORE GAS AND IT SPEEDS UP. THE LAST COUPLE OF TIMES THIS HAPPENED, THE CAR LOST ALL POWER AND STAHLED.

ENGINE

I WAS DRIVING MY VEHICLE WHEN IT SUDDENLY STALLED AND WOULD NOT START, I HAD IT TOWED TO A MECHANIC AND WAS ADVISED IT NEEDED AN ENGINE, THIS WAS A KNOWN PROBLEM WITH THE 2008, 2009, 2010 BUICK ENCLAVES, BECAUSE OF THE OIL PUMP DRAINING THE ENGINE OF OIL IT SEIZED THE ENGINE. I CALLED GM AND ASKED WHY THEY HAVEN'T RECALLED THE 2010 ALONG WITH 2008, AND 2009 MODELS WITH THE SAME ENGINE AND ISSUE. THEY SAID ITS BEEN ACKNOWLEDGED BUT THERE IS NO FUTURE DATE IF OR WHEN THE 2010 BUICK ENCLAVE WOULD BE RECALLED FOR THE ENGINE- OIL FAILURE! THIS COST OVER $4800 DOLLARS TO GET FIXED, I JUST PURCHASED THE CAR FROM A DEALERSHIP LESS THAN A YEAR PRIOR, VERY DISAPPOINTED WITH DEALER FOR NOT MAKING ME AWARE TO CHECK OIL EVERY FEW DAYS SO THIS WOULDN'T HAPPEN. I ALSO JUST HAD THE OIL CHANGE DONE A MONTH BEFORE THE ENGINE SEIZED!

ENGINE

2010 BUICK ENCLAVE WITH 116,164 MILES, JUST OVER 10,00 PER YEAR, ENGINE DEVELOPED A SPUN ROD BEARING AND QUIT WHILE DRIVING. STEERING LOST POWER AND ENGINE STOPPED. I HAD TO PUSH IT BACKWARDS TO GET OUT OF AN INTERSECTION. I HAD JUST STARTED A RIGHT TURN. 22 MONTH EARLIER THE TIMING CHAIN STRETCHED ON THE VEHICLE COSTING $2000 IN REPAIRS. OIL WAS CHANGED EVERY 5000 OR LESS MILES AND USED MOBILE 1 SYNTHETIC OIL THE ENTIRE TIME. THIS AND OWNERS OF EARLIER MODEL YEARS REPORT THIS SAME PROBLEM FROM THIS VEHICLE. A WELL MAINTAINED VEHICLE SHOULD NOT HAVE THESE TWO PROBLEMS WHICH POINTS TO SOME FAILURE IN DESIGN OR MANUFACTURE. VEHICLE IS NOW JUNK.

ENGINE

THE CAR SHUT OFF WHILE I WAS DRIVING IT, I WAS STARTING TO GO FROM SITTING AT A RED LIGHT AND IT JUST SHUT ITSELF OFF! I'VE JUST PURCHASED THIS CAR AND ALREADY IT'S A HUNK OF JUNK. ALSO THE AMOUNT OF ELECTRICAL PROBLEMS CAUSED BY WATER ENTERING THE MOTOR COMPARTMENT IS RIDICULOUS AND SHOULD BE A RECALL AS IT'S JUST A BAD DESIGN. THE AC FAN MOTOR LOCATED ABOVE THE PASSENGER FLOOR FILLS WITH WATER AND RUINS THE MOTOR. THE CAR SHUT OFF TODAY BECAUSE OF SHODDY SOLDERING.

I AM WRITING BECAUSE WE PURCHASED A 2010 BUICK ENCLAVE IN 2018. IMMEDIATELY AFTER PURCHASING I NOTICED ISSUES WITH THE VEHICLE AND IT HAD TO BE SERVICED TWICE WITHIN A COUPLE WEEKS OF HAVING IT. AT THE TIME THE SERVICE DEPT. COULD NOT DIAGNOSE THE ISSUE AND BLAMED IT ON MY ACCIDENTALLY TOUCHING THE MANUAL SHIFT ON THE SHAFT. I KNEW I WAS NOT DOING THIS. I HAVE VIDEO OF THE CAR DOING THIS WEIRD ACCELERATION AND ALL DURING THE LAST COUPLE OF YEARS BUT [XXX] KEPT SAYING THE VEHICLE WAS FINE. WELL, I WAS STRANDED BECAUSE IT JUST STOPPED A FEW DAYS AGO AND HAD TO TAKE A 50.00 UBER HOME. I HAVE HAD TO UBER 3 TIMES NOW AND PURCHASED A CODE READER. THE CODE COMES BACK AS A TIMING CHAIN STRETCHED. IT SEEMS WHAT I WAS FEELING FROM THE VERY BEGINNING WAS IN FACT THIS ISSUE. I AM NOT HAPPY ABOUT THIS. I HAVE HAD TO RENT VEHICLES FOR THE LAST 3 DAYS AND WILL HAVE TO HAVE THE VEHICLE TOWED BACK TO MY HOME TOMORROW. SINCE THIS ISSUE WAS BROUGHT TO YOUR ATTENTION FROM DAY ONE I EXPECT IT TO BE REPAIRED AT NO COST TO ME AND SOME OF THE CHARGES I HAVE ACCUMULATED BE REIMBURSED. THIS IS NOT JUST! I WILL BE LOOKING INTO THE LEMON LAW AND IF IT APPLIES TO ME. I AM HOPING YOUR COMPANY TAKES RESPONSIBILITY. HAD THEY PAID ATTENTION TO WHAT I WAS SAYING AND ALL THEN THIS WOULD NEVER HAVE HAPPENED,. THE STRESS AND ISSUES THIS HAS CAUSED GOES SO MUCH DEEPER THAN THIS THE CODE THAT COMES BACK IS P0008. THE CRANK SHAFT. I HAVE READ NUMEROUS REVIEWS ON THIS AND WILL CONTINUE TO CARRY THIS ON. FURTHERMORE THE FACT THAT THERE ARE RECENT ISSUES WITH THE POWER STEERING AS WELL. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

WELL WHAT HAPPENED WAS THE VEHICLE DEAD STOPPED IN THE MIDDLE OF TRAFFIC. THIS MAY NOT SEEM UNUSUAL, BUT THIS PARTICULAR VEHICLE HAS BEEN REPORTED FOR THE SAME ISSUE, P0008 WHICH IS A STRETCHED TIMING CHAIN ISSUE. THIS ISSUE SEEMS TO BE COMMON WITH THE 3.6L VVT ENGINE THAT IS SHARED ACROSS ALL MODELS. MY WIFE AND CHILD WERE IN THE VEHICLE AT THE TIME AND WERE ABOUT TO BE HIT BY ON COMING TRAFFIC. LUCKILY, THE VEHICLE COMING TOWARD THEM WAS ABLE TO GET OUT OF THE WAY. THE VEHICLE BLOCKED TRAFFIC FOR SEVERAL HOURS. THE DESCRIBED PROBLEM IS A STRETCHED TIMING CHAIN, BUT MY RESEARCH HAS ELUDED THAT GM HAS HAD THIS SAME ISSUE WITH MULTIPLE MODELS OVER MULTITUDES OF MODEL YEAR VEHICLES. THIS ISSUE OFTEN LEADS TO A HEFTY REPAIR BILL UPWARDS OF $3500 OR EVEN MORE. IN MY OPINION WITH MULTIPLE REPORTS OF THIS VEHICLE OR MODELS THAT SHARE THE SAME ENGINE, THE PROBLEM CAN LEAD TO POSSIBLE SAFETY CONCERNS FOR A DEAD STOP WHILE DRIVING. A VEHICLE COULD POSSIBLY BE ON ICY, WET, ROAD CONDITIONS AND COULD CAUSE A GREAT DEAL OF MORE INJURIES. I BELIEVE THAT THIS ISSUE SHOULD BE LOOKED INTO FOR MODEL YEARS FROM 2008 - 2020. THE ENGINE HAS NOT CHANGED. THIS ENGINE IS NOT ONLY SHARED WITH THE BUICK ENCLAVE, BUT THE CHEVY TRAVERSE, GMC ACADIA, BUICK LACROSSE, AND THE LIST GOES ON. DUE TO THE TIMING CHAIN FAILURE, MY FAMILY COULD HAVE BEEN SERIOUSLY HURT OR WORSE. PLEASE LOOK INTO THE DESIGN ISSUE. I'M GLAD THAT MY FAMILY IS OK. NOW, I HAVE A HEFTY $3500 REPAIR THAT I NEED TO TAKE CARE OF FOR A CAR THAT I STILL OWE MONEY ON. GM NEEDS TO GET IN FRONT OF THIS AND PROVIDE SOME TYPE OF RELIEF FOR THEIR CUSTOMERS. GM KNOWS ABOUT THE ISSUE. IN 2011 GM RELEASED CUSTOMER SATISFACTION PROGRAM 10287 WHICH DIDN'T WORK THEN IN 2012 GM RELEASED A SPECIAL COVERAGE ADJUSTMENT (#11340C) EVEN WHEN PROPER OIL CHANGES ARE DONE. PLEASE LOOK INTO

THE AIR CONDITIONER HOSE WAS MELTED WHERE IT TOUCHES ANOTHER HOSE, THERE WAS AN ACADIA AND A TRAVERSE THAT HAD THE SAME PROBLEM. WHEN I CALLED BUICK TO SEE IF THERE WAS A RECALL, I WAS TOLD ONLY YUKON HAD THE RECALL. I HAVE A PROBLEM WITH THIS, THEY ARE BASICALLY THE SAME. THEY KNOW THESE HOSES RUN TOO HOT NOT TO BE SEPARATED OR AT LEAST INSULATED. THE PART COSTS AN INSANE $861 DOLLARS. ALL OF THESE VEHICLES NEED TO BE RECALLED OR CORRECTED.

TODAY I WAS DRIVING TO WORK, AS I PULLED INTO THE DRIVEWAY OF WORK TICKING NOISE STARTED AND THEN CAR DIED RIGHT ON A HILL BLOCKING TRAVEL, IT WOULD NOT RESTART, SO I HAD IT TOWED TO MY MECHANIC WHO ADVISED ENGINE BLOWN DO TO TIMING BELT WEAR...ALL MY OIL WAS SUCKED INTO ENGINE (JUST HAD AN OIL CHANGE 2 MTHS AGO) AND BLEW THE MOTOR! THIS IS A KNOWN PROBLEM WITH THIS YEAR, MAKE, MODEL OF BUICK, WHY IS NO ONE DOING ANYTHING ABOUT A RECALL! I CAN'T AFFORD A NEW ENGINE, NOR A NEW CAR, I JUST PURCHASED THIS USED AT HURD BUICK IN RHODE ISLAND 5/2017 EXPLAINED NEEDED DEPENDABLE CAR, I'M A SINGLE PARENT WORKING FULL TIME AND THEY GAVE ME A LEMON KNOWING FULL WELL THE ENGINE PROBLEMS WITH THIS MIDEL! NHTSA NEEDS TO MAKE GM ACCOUNTABLE TO THE CONSUMER OF 2010 MODELS LIKE THEY DID WITH THE 2008-2009 MODELS THIS IS SO UNFAIR. I HAD TO RENT A CAR TO GET BACK AND FORTH TO WORK...I DON'T KNOW WHAT OR HOW I'M GETTING AROUND NEXT WEEK!
