Parking Brake Fails Safety Standards May Cause Unintended Vehicle Movement

Certain sport utility vehicles fail to conform to the requirements of Federal Motor Safety Standard # 135 "Passenger Car Brake Systems" To meet the standard, vehicles must not move for 5 minutes when stopped on a steep hill with the parking brake applied and the vehicle in neutral. Some of these vehicles failed this test. When the parking brake is released the driver may notice unintended braking while accelerating, decelerating or coasting. This could lead to unintended vehicle movement and cause an accident. The dealer will inspect each rear parking brake caliper and replace free of charge if slippage is noticed. The GM recall # is 05059
