Exactly what failed

NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2011 Buick Lacrosse

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2020615 10,006 units in Canada

Suspension

Issue: On certain vehicles, the protective coating on the rear suspension toe links may chip away. If this happens, the metal can rust and the toe link could break. A broken toe link can affect vehicle stability and could cause a loss of directional control. Note: This recall only affects vehicles that were originally sold or ever registered in areas of heavy road salt usage (Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador). Safety Risk: A loss of vehicle stability could cause a loss of control and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the rear suspension toe links and adjuster fasteners.

Recall 2014311 29,555 units in Canada

Seats And Restraints

On certain vehicles equipped with power height adjustable front seats, a bolt securing the adjuster mechanism may loosen and fall out. This would cause the seat to drop to the lowest vertical adjustment position, which could affect the driver's ability to safety operate vehicle controls as well as cause reduced driver visibility. These issues could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the bolt.

Recall 2011103 568 units in Canada

Heater And Defroster

Certain vehicles fail to conform to Canada Motor Vehicle Safety Standard 103 - Windshield Defrosting and Defogging. Software in the Electronic Climate Control (ECC) module may disable the ability to adjust the Heating, Ventilation, and Air Conditioning (HVAC) system settings. If this happens, the driver will not be able to control the heating, cooling, and ventilation of the vehicle. Loss of windshield defrosting and defogging function may, under certain driving conditions, compromise the driver's ability to see the road and its users, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will reprogram the ECC module.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

Decatur, GA

ELECTRICAL SYSTEM

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.

SERVICE BRAKES

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

VISIBILITY/WIPER

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.

UNKNOWN OR OTHER

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.

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.
