2007 GMC Topkick recalls (5)
Tap a recall to see the problem, the risk and the fix.
Service brakes, air:supply:compressor
Problem: Gm is recalling 1,880 model year 2007 chevrolet kodiak and t-series, gmc topkick and t-series, and isuzu f-series and h-series passenger vehicles equipped with 7.8l diesel engine. The air compressor in some of these vehicles may not build enough air pressure to support the air brake system. If this condition were to occur while the vehicles was stationary (brakes applied), the air brakes would remain applied and prevent the vehicle from moving.
Risk: If the driver ignores these warnings and continues to drive the vehicle, and if there was a continued loss of pressure, the rear spring parking brakes would automatically apply, preventing the truck from being driven.
Fix: Dealers will inspect the air compressor for its ability to build air pressure, and either modify the air compressor by elimination of the suppression valve or replace the air compressor assembly free of charge. The recall is expected to begin during august 2009. Owners may contact chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, isuzu at 1-800-255-6727 or at www.gmownercenter.com.
Steering
Problem: On certain medium duty trucks equipped with zf model 8018 steering gears, the steering gear may have been produced incorrectly. A steering gear with this condition may produce the feeling of hitting a curb and a cracking or pinging sound when the steering wheel is turned.
Risk: The steering wheel position may be off-center and increased effort may be required when turning, increasing the risk of a crash.
Fix: Dealers will inspect for certain date codes and verify the mileage on steering gears and replace gears as necessary. The recall began on october 25, 2007. Owners may contact chevrolet at 1-800-630-2438; gmc at 1-866-996-9463; or isuzu at 1-800-255-6727.
Parking brake
Problem: On certain straight towing or non-towing trucks equipped with bendix air brakes, the air brake park control valve may develop either an internal air leak or an air restriction. The park brake may not release or may release only partially.
Risk: If the vehicle is on an uneven surface, the park brake may not hold the vehicle and could result in unintended vehicle movement and a vehicle crash. This condition does not affect normal service braking.
Fix: Dealers will inspect and replace the external check valve on the air brake park control valve if the inspection determines the external check valve is damaged, the air brake park control valve will be replaced and may require the replacement of an internal check valve in the air brake park control valve. Remedy will be free of charge. The recall began on october 22, 2007. Owners may contact gm at 1-800-862-4389 or isuzu at 1-800-255-6727.
Service brakes, air:supply:compressor
Problem: On certain medium duty conventional and tilt cab trucks equipped with 7.8l diesel engines and air brakes, the air compressor may not build enough air pressure to support the air brake system.
Risk: If this condition were to occur while the vehicle was stationary (brakes applied) the air brakes would remain applied and prevent the vehicle from moving. If this condition were to occur while the vehicle was in motion, the dual system air pressure gauges would register the drop in pressure. If the pressure continued to drop, the low air pressure warning buzzer and warning lamp would activate as designed, warning the driver to move the vehicle to a safety location. If the driver ignores these warnings and continues to drive the vehicle, and if there was a continued loss of pressure, the rear spring parking brakes would automatically apply, preventing the truck from being driven.
Fix: Dealers will replace the air compressor head. The recall began on may 23, 2007. Owners may contact chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, or isuzu at 1-800-255-6727.
Power train:axle assembly
Problem: On certain trucks, the rear drive axle housing was manufactured with steel below the specified thickness and, as a result, it could develop a crack.
Risk: If a crack develops and is not detected and repaired, the outboard end of the housing could eventually separate, allowing the hub, axle shaft, or wheel and brake assembly to separate from the vehicle increasing the risk of a crash.
Fix: Dealers will inspect and replace the axle free of charge. The recall began on april 12, 2007. Owners may contact chevrolet at 1-800-630-2438 or gmc at 1-866-996-9463.
