The specific potting compound used in the subject products for insulation was found to be capable of conducting electricity after being exposed to heat.

Risk

Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.

Recall number 14V070000 · 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.

Recall number 07V190000 · Recall details

What is wrong

Certain medium duty trucks equipped sr-7 bendix brake valves, the check valve inside the valve cavity may not properly set, causing internal air leakage. If the check valve does not properly seat, the resulting leakage can cause a delay in the application of the spring brakes to park the vehicle after operator pulls the dash valve button.

Risk

The delayed parking brake application can occur without warning, leading to unintended vehicle rollaway increasing the risk of a crash.

Remedy

Dealers will inspect the valves and replace it free of charge. The recall began on july 31, 2006. Owners may contact chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, or isuzu at 1‑800‑255‑6727.

Recall number 06V254000 · Recall details

What is wrong

Certain medium duty c-series and b7 school bus chassis equipped with a 7.4 liter gas engine and an impco lpg conversion kit. Some of these vehicles may have engine backfires with sufficient force to damage the engine air intake system and the air cleaner filter element.

Risk

If the damaged air cleaner parts are dislodged from their normal position, these parts could come in contact with the hot exhaust manifold and/or hot exhaust gas recirculation (egr) valve tube resulting in a possible engine compartment fire.

Remedy

Dealers will install a redesigned mixer bonnet and air cleaner housing cover, selective upgrades in various connections related to the air induction system, and if needed, a new air cleaner filter. Owner notification began december 18, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020 or gmc at 1‑800‑462‑8782.

Recall number 02V287000 · Recall details

What is wrong

On certain medium duty trucks equipped with 8.1 l engines and left hand or dual fuel tanks, some of these vehicles have a condition where the fuel filter-to-component box mounting bolts are reversed. With the bolts reversed, the threaded bolt end is oriented toward the front wall of the left hand fuel tank.

Risk

In the event of a frontal crash, the threaded end of the bolts could pierce the front wall of the fuel tank resulting in flue leakage. If an ignition source were present, fuel leakage could result in a vehicle fire.

Remedy

Dealers will inspect and correctly install the two fuel filter mounting bolts, if necessary. Owner notification began august 8, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020 or gmc at 1‑800‑462‑8782.

What is wrong

Vehicle description: school buses, medium duty trucks and tractors built with bendix air ABS with an ec-17 1030r electronic control unit (ecu), there have been reports of unwanted ABS activation at low speeds caused by 1) chafed ABS wheel speed sensor wires on rotating parts or 2) a damaged component at the wheel end that generates a certain type of erratic sensor signal.

Risk

This condition could cause the ABS ecu to exhaust the air at the air brake modulators for one or more of the wheels. This could result in extended braking distances and a possible crash.

Remedy

Dealers will replace the ABS ecu.
