On certain vehicles, the parking brake operating shaft in the rear brake caliper could rust and become stuck. If this happens, the parking brake may not work properly. As a result, the brakes could drag or parking brake performance could be reduced. If the vehicle is not left in in gear when it is parked, it could roll away.
A parked vehicle that rolls away could create the risk of an injury or a crash.
Mitsubishi will notify owners by mail and instruct you to take your vehicle to a dealer to replace the rear brake calipers.
