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.
A loss of vehicle stability could cause a loss of control and increase the risk of a crash.
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.
