“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…”

“When going around town or on the highway the steering wheel will start shaking badly and when going to break even after the breaks have been changed the parking break will not stay on and the steering wheel will start shaking horribly to the point where your might crash your car I have had the car looked at multiple times by different manufacturers dealerships and auto shops and they all say to Change the breaks I tell them that I had them changed by Buick and Chevrolet of Dan Cummins where I had got the car and they done the same thing over again as when I bought the car”

“When driving in rain and high humidity, the windshield and front windows will often completely fog up with moisture on the inside of the car. It can make seeing outside while driving impossible and risks an accident. In three years we have found no settings on the climate control system that will avoid this problem. We have had the heater core replaced in a futile attempt to remedy the situation. We have been told by Buick that there is no fix or recall.”
