No first gear. Engine stalls if car is brought to a halt. On take off, car will stall if given too much throttle. If able to roll from dead stop, it will jerk and hesitate as if in too high of gear or dragging clutch.

Shortly after purchasing my 2017 enclave premium around 60000 I noticed a problem that felt like vehicle's tires were skipping when making sharp turns. Upon my own extensive research (as I didn’t have time money and couldn’t go won’t vehicle) discovered a clutch pack needed replaced. This is after replacing the battery and brakes nit even a month after buying. Later after taking it for an oil change I received a report stating the rear differential was cracked and power steering rack needed replaced. While driving in rush hour traffic one day all power steering was lost with no explanation. Still having problems with tire pressure monitor replacing multiple tire stems and tires. Won’t start after filling with gas or is stuck in crank position trying to start when it finally dies it wants to stall out. Currently headlights are flickering with no known cause. Oh and the driver heated seat stopped working right after purchase. I’m at a huge loss with repairs costing more than the worth of a vehicle that continues to have serious issues even after fixing the problem it seems to repeat itself. Owe too much to trade in. All these problems are known to occur I cannot believe this isn’t a lemon or recalled parts. If not in enclave same thing happens in similar vehicles made by sane manufacturers during the same years. I will never purchase another GMC nor purchase from Toyota who failed to help after purchase.

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 the federal safety agency should be aware of the potential risk.

What component or system failed or malfunctioned, and is it available for inspection? The issue appears to be related to the auto start-stop system and/or an EVAP-related component, as the vehicle will sometimes completely shut off instead of restarting when stopped. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? When the engine shuts off, the vehicle loses all power, including steering and brake assist. This has happened at red lights, stop signs, and in school zone traffic. I have to restart the vehicle while stopped in active traffic lanes, which puts me and others at high risk of being hit. I am a single mom with 3 young children. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. A Buick dealership inspected the vehicle earlier this year. They observed the stalling issue but could not identify a single cause. They suggested possible repair attempts, but the issue has continued. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? It has only been inspected by a Buick dealership service department. No other agencies have inspected it. Were there any warning lights, messages, or other symptoms prior to the failure? When did they first appear? No warning lights or messages appeared when it first happened. The problem began before I replaced the battery, and replacing the battery did not resolve the issue. Additional Description: When I come to a stop—at red lights, stop signs, or in traffic—the vehicle’s auto start-stop system activates like normal, but instead of restarting, the engine will completely shut off. I then lose power steering and braking support and must restart the car in the middle of the roadway. It is unpredictable and unsafe. Sometimes it’s instantly but today I sat there for 15 minutes waiting. I took it straight to autozone and everything tested good.

The vehicle began shuddering and losing power during normal driving. The issue occurs at various speeds, especially between 35–60 mph, and feels as though the car is slipping or will stall. A certified service center diagnosed a failing torque converter, which is part of the transmission/power train. The repair estimate was several thousand dollars. This failure poses a safety risk because the vehicle can suddenly lose acceleration or struggle to move in traffic. The service center confirmed the defect but stated there is no recall or assistance from Buick or GM. I have contacted Buick Customer Care and GM Executive offices with no response. The vehicle remains unsafe to drive.

The dealership is unable to identify the failing component or system. The vehicle shuts off while driving above speeds of 60mph, which causes the power steering pump and power brake pump to fail. This symptom of shutting off while driving creates a significant life safety risk for the driver, passengers, and other motorists. The vehicle has been inspected by the dealership over 4 times in 3 months. Since the vehicle shuts off, there are no warning lamps, messages or other symptoms prior to the failure.

The car stalled and is stuck in park. It has electronic shift and if the engine doesn't run it has to be put into neutral manually. The Buick dealerships don't know how to do this and keep referring me to an obsolete video. One service representative suggested the manual lever is under the air filter housing but they cannot provide any information on this design, The car is stuck in a garage and cannot be towed. It is stuck in place.
