Suspension: rear
- What is wrong
- General Motors, LLC (GM) is recalling certain 2010-2013 Buick Lacrosse, 2012-2013 Buick Regal, and 2013 Chevrolet Malibu vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received an improper amount of electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately fracture.
- Risk
- A rear toe link fracture may reduce the driver's ability to control the vehicle, increasing the risk of a crash.
- Remedy
- Dealers will replace the rear suspension toe links and adjuster fasteners, free of charge. Owner notification letters were mailed January 27, 2022. Owners may contact Buick customer service at 1‑800‑521‑7300 or Chevrolet customer service at 1‑800‑222‑1020. GM's number for this recall is N212346640. This recall is an expansion of the federal safety agency recalls 20V‑764 and 21V‑633.

What 2011 Buick Lacrosse owners say
Most recent owner complaints, unedited.
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.

#07-06-04-019F: Intermittent Malfunction Indicator Lamp (MIL} Illuminated, OTC Pl':1.~J with Reduced Engine Power (Repair Instrument Panel (IP) to Body Harness Connector). Lost power on I-84 and had to cross over the right lane because I had no power, barely missing a rear end collision.
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
Car lost all steering while driving down the road
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.
