All three recalls describe the same underlying defect: the rear toe links losing their protective coating, rusting, and potentially fracturing.
The 2010 Buick LaCrosse has 3 recalls, all concerning the same rear suspension defect where toe links can rust through and break, causing the vehicle to lose directional control and raising the risk of a crash.
The toe links are small but critical rods that keep the rear wheels pointed in the correct direction. When the protective coating on these links chips away, bare metal is exposed to moisture and road salt, and the links can corrode to the point of fracturing. If a toe link breaks while driving, the rear axle geometry shifts unpredictably, and the driver may feel the rear end pull or dart to one side with little warning. These recalls appear to be focused on vehicles registered in states and regions with harsher winters and heavy road salt use, where corrosion risk is highest.
