By System
The 2010 Buick LaCrosse has 3 recalls, all concerning the same rear suspension toe link defect: the protective coating on these links can chip away, allowing rust to develop until the link breaks and the driver loses directional control.
The toe link issue is particularly relevant for vehicles registered or sold in northern and mid-Atlantic states where road salt is common, as corrosion is the primary way this part fails. A broken toe link changes the angle of the rear wheels without warning, which can make the car difficult to steer and raise the risk of a crash.
