2007 GMC TOPKICK 8500Transport Canada Recall #2009234
Defect
On certain trucks, the air compressor may not built enough air pressure to support the air brake system. If this condition were to occur while the vehicle is stationary (brake applied), the air brakes would remain applied and prevent the vehicle from moving. Should it occur while the vehicle is in motion, the rear spring parking brakes would engage, slowing the vehicle to a stop, and preventing it from being driven.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the air compressor for its ability to build air pressure, and either modify the air compressor by eliminating the suppression valve or replace the air compressor assembly altogether.
