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.

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.

Purchased new, dealer twice during warranty kept vehicle for 6 weeks to do recall notice repairs. Now this 2010 has 42,000 miles and the steering is going bad. SB10056459-3388 describes the exact problem. During these two periods that recall repairs were done that should have addressed the problem even though the problem had not surfaced yet. This was a wear condition i was never informed of. It is getting worse now.
