2007 Isuzu F Series problems

What is wrong

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.

Remedy

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.

Recall number 09V309000 · Recall details

What is wrong

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.

Remedy

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.

Recall number 07V385000 · Recall details

What is wrong

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.

Remedy

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.
