2010 Buick Enclave

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.

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.

I purchased a 2010 Buick Enclave from a dealer who did not disclose any major issues with the vehicle. After purchase, I began experiencing significant problems while driving, including difficulty shifting, loss of power, and unstable handling. Concerned for my safety, I took the Buick to a mechanic for inspection. The mechanic verified that: •The wrong transmission had been installed in the vehicle, causing unsafe shifting and performance issues. •The driveshaft was malfunctioning, which affects the stability and control of the SUV. •No warning or check engine lights were on •CV axel bolts were zip tied closed Because of these defects, the mechanic told me the vehicle is not safe to drive. These problems were never disclosed to me at the time of sale, and I would not have purchased the vehicle had I known.

The timing chain broke and my transmission needs to be replaced.

Bad timing chain at 141,000 miles

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.

Car was running just fine had its oil changed new tires added and it just stopped running. Got it checked with a car technician and he stated it’s the engine.

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.

When the driver seat is moved the service air bag light comes on. When you move the seat again the light goes off.

This was a wear condition i was never informed of. It is getting worse now.

I have 2 of these booster seats and both of them the back is no longer locking into the base. It folds as the child is getting into the Seat. It doesn't stay in place even if the child has their car seatbelt on making it dangerous while riding in it as it may fold. I have not had it inspected. I am just wanting to know what you can do to help me. Also, thus won't let me put the correct Manufacturer date of 09/21/2019 in.

The power steering has issues when turning it seems to not work. Been have this problem for about a year. I’ve talked to other Buick owners and they have the same problem. I also have electrical issues on the drivers side door panel, where none of the switches work. Just all of a sudden quit.

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!

THE 2010 BUICK ENCLAVE HAS BEEN WELL KEPT. I HAD JUST PURCHASED IT AND ONLY DROVE IT FOR 2 MONTHS. I WAS DRIVING ON THE FREEWAY AT 70MILES PER HOUR THEN THE CHECK ENGINE LIGHT CAME ON AND THE CAR LOST POWER DOWN TO 40MILES I HAD TO PULL OFF THE FREEWAY. ALMOST HIT. THE HOLE SYSTEM SHUT DOWN IT WOULDN'T START AT ALL HAD IT TOWED TO THE DEALER THEY SAID THE TIMING CHAIN JUMMPED AND LOCKED UP YOUR MOTOR IT WILL BE 10 THOUSAND TO FIX I DONT HAVE THAT KIND OF MONEY SO NOW I M PAYING A LOAN ON A CAR THAT DOES NOT WORK.

WHILE DRIVING IN SINGLE DIGIT TEMPS IN ICY ROAD CONDITIONS IN TRAFFIC USING THE BRAKES A LOT MY TRACTION CONTROL LIGHT CAME IN AND I GOT A SERVICE YOUR TRACTION CONTROL SYSTEM AND ENGINE POWER WAS REDUCED CAUSING ME TO NOT HAVE CONTROL OF THE VEHICLE IN HEAVY TRAFFIC AND DANGEROUS ROAD CONDITIONS. TRACTION CONTROL WILL NOT COME BACK ON AFTER THE VEHICLE HAS BEEN TURNED OFF AND RESTARTED. ROAD CONDITIONS WERE SO BAD TRAFFIC WAS MOVING 5-10MPH ON HIGHWAY. THE REDUCED ENGINE POWER HAPPENED AS SOON AS I STARTED TURNING RIGHT ON ANOTHER ROAD DUE TO HOW SLICK THE HIGHWAY WAS.
