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.

I was driving down the highway and when I went to apply my brakes the pedal completely broke off. It was just dangling on the floorboard. I had no brakes. I was forced to put my car in neutral to slow myself down and apply my parking break in order to stop. The road was very busy and I was going 60mph. I could have died. Luckily I was able to make it over 2 lanes and stop in the grass on the side of the road. I had the car towed to my mechanic and he had to replace the whole brake assembly. I have the broken parts and they are available for inspection. There were no warning lights

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.

The brakes are getting stuck on while I am driving. The most recent occurrence happened while I was on the highway. The car would not accelerate, the whole system was shaking, there was no safe space for me to pull over. This vehicle has a recall for this exact problem but from what the dealer is saying, not my VIN. I find it hard to believe that this has occurred and it is unrelated to a previous recall for faulty brakes on 2011 Buick LaCrosse. Since this incident, the abs light has been on and another dash light has been on. My mechanic believes the brakes getting too hot may have lead to further damage to the abs sensor.

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

I noticed today as I was stopped at a red light with my foot on brake the vehicle was kinda jumping like it was trying to go while foot was on brake. I drove a little further and the service stabilitrak light came on followed by the reduced engine power. The car proceeded to die in the middle of a busy street. After a few minutes it did restart and I was able to get it home. This seems to be a common problem with 2011 buick lacrosse. Ihave seen several complaints about this same issue.
