I am reporting a serious safety defect involving a 2011 Buick LaCrosse CXL. The vehicle has repeatedly shut off while being driven, creating a dangerous situation. The issue first occurred in January 2026. The vehicle was later towed for repair in February 2026, and I was told the issue had been fixed and picked up the vehicle 3/20/2026 and gave $1600. However, on April 9, 2026, the vehicle shut off again while driving. This issue has occurred multiple times and persists despite repair attempts. When the vehicle shuts off, it creates a loss of power and poses a significant safety risk in traffic. I am concerned that this may be a broader safety issue and am requesting that this defect be documented and investigated.

The component is the brakes and the brake pedal while not engaging the brakes they remained on even after the vehicle was shut off .the vehicle brake lights remained on this was not duplicated when I took the car in by the dealer of how the brake remains engaged we even when not being used I would have to release the break by pulling it up with my foot while driving . This was duplicated and witnessed by two others the dealership where I bought the car and a trusted mechanic. which no avai there was no warning light indicating any type of concern prior to it doing this. the brake pedal being slightly stuck my transmission shifts not properly and hot feeling to the car now I have a warning saying that AC will not work due to the overheating of my engine which I believe to have repaired however the repair that was believed to be the problem obviously wasn't the problem because the light still remains on and the fan runs continuously the minute I start the car to the time I shut the car off I live in North Dakota and it is -1 today and the fan continues to run at all times and the warning light is on cooling fan the car lunges at times which is easy to lose control over when it does this it lunges to the point where it physically noticeable and and no warnings of this that a compensation is going to need to be made in my driving with this lunge issue. I do feel this break issue has affected many other parts of the vehicle and the safety associated with these components. Also at times the driver's seat will not move it goes up to the dash or back to the back seat leaving me in a position where I cannot drive the vehicle safely at all. Also the cruise control would not engage because of the brakes being slightly engaged. Took her to the dealership discussed this problem with them and they could not duplicate and it's been going on since I purchased the car It had 30,000 miles on it when I bought it and it continues to do this and I think it's a safety issue

Driving 60 MPH on the highway. Suddenly the information panel flashed stabilitrak service required (or similar) then low power mode. Car went from 60 to 30 MPH on the highway. Unable to speed up. Needed to pull over to the side of the road. Turned car off. Tried to restart and it wouldn't restart for several tries. Restarted and still said low power and was idling low. Tried again and was normal. This has happened several more times and always is similar. Sometimes it doesn't happen at all in a 30 mile trip, sometimes it happens 3 times. Very dangerous! Could be rear ended! I have read many other accounts of this happening in the 2011 buick lacrosse. After this the check engine light stayed on. When I had the auto parts store run diagnostics it flagged multiple misfires, throttle position sensor 3 times, power control module indicator, traction control. It seems this is a flaw in this car. I attempted to get a picture of the satbilitrak sensor indicator light, but it flashes on and off pretty quickly and you never know when it will happen.
