Causes the technical documents say how to deal with (12)
Brake pipe (brake line) corrosion and rupture
4 matching records
The pipes' steel-copper construction is vulnerable to galvanic corrosion if exposed to the environment.
NHTSA found the failures came with general excessive corrosion over most of the pipe assembly and appear to be expected wear-out of the coating in severe-corrosion states.
How to tell
What to do
- In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).
- GM noted that pipes with excessive flaking corrosion can only be fully evaluated, including remaining service life, by removing them, cleaning off the corrosion and sectioning them to assess remaining wall thickness.
- The inspections found no specific location where corrosion was visually more severe and no pattern between vehicles.
- Service records of incident vehicles also indicate that repairs are not isolated to a specific location or brake pipe.

HVAC blower motor resistor module / connector overheating
2 matching records
The terminal interface between the relay resistor module and its power connector may be unable to carry higher current for sustained blower operation.
Moisture and contaminants may enter the fresh air intake plenum and reach the module's circuit or corrode the terminals.
What to do
- Dealers install a new blower motor resistor and resistor module connector.
- Cut the wires back far enough to remove any melted insulation.
Fuel module reservoir assembly: fuel pump wire connectors may overheat - recall 05V-155
2 matching records
The fuel module reservoir assemblies contain fuel pump wire connectors that may overheat under certain operating conditions.
The terminals in the 4-wire electrical connector at the top of the fuel pump assembly may suffer fretting and high resistance.
How to tell
What to do
- On-board emissions diagnostics may detect holes of approximately 0.040 inches (= 1.02 mm) or more and set a service engine soon warning light. The connector sits below the fuel level when the tank is full.
- Dealers remove the fuel tank and the module reservoir assemblies and install a new service kit.
- The bulletin explains how to install repair kit 15824379 on the fuel pump assembly; the kit contains replacement electrical connectors, a replacement fuel level sensor, related hardware and instructions.
- Installing the replacement connector components in the cover is a new procedure; the fuel level sensor is replaced by the existing SI procedure, but the float assembly is re-used, which is new.

Engine fuel rail crossover tube retainer screws may break (5.3L RPO L59) - recall 04V-376
2 matching records
The engine fuel rail crossover tube retainer screws were not manufactured to specification and may break.
The failed screw was harder than specification; the over-hardening came from a conveyor in an induction hardening operation at the fastener plant stopping or slowing excessively, exposing the screws to the hardening for too long.
What to do
- Check for leaks: ignition ON with the engine OFF for 2 seconds, ignition OFF for 10 seconds, ignition ON with the engine OFF, then visually inspect for fuel leaks.
- Dealers inspect the fuel rail crossover tube and replace the retainer screws if necessary.
- Hold the fuel crossover tube retainer to the bracket on the fuel rail with locking pliers, using enough force to keep the retainer from moving without damaging any parts.
- Remove the fuel rail crossover tube bracket retainer screw on one side and dispose of it properly.

Engine fuel rail pulse damper retainer clip may fracture (8.1L V8) - recall 06V-289 / Transport Canada 2006195
2 matching records
The engine fuel rail pulse damper retainer clip may fracture, leaving the damper inadequately retained.
On certain vehicles, the engine fuel rail pulse damper retainer clip may fracture, resulting in inadequate retention of the damper.
What to do
- To inspect for leaks, turn the ignition ON with the engine OFF for 2 seconds, turn it OFF for 10 seconds, turn it ON with the engine OFF, and inspect the fuel rail, fuel rail dampener, and fuel rail pressure cap and valve for fuel leaks.
- Dealers replace the engine fuel rail pulse damper retainer clip.
- Dealers replace the engine fuel rail pulse damper retainer clip.
- Part: 12575017 Clamp-Fuel Pulse Dpnr, quantity 1 per vehicle.

Mid-frame cross member tear could puncture fuel tank in angled frontal impact - recall 03V-019
2 matching records
In a sufficiently severe 30-degree left angle frontal impact, a tear could develop in the mid-frame cross member where it attaches to the left frame rail.
What to do
- Dealers install a fuel tank shield.
Positive battery cable contact with steering shaft universal joint (Denali) - Transport Canada 2001092
1 matching record
The positive battery cable assembly could contact the steering shaft universal joint.
What to do
- Dealers inspect the cable routing and reroute if necessary.
- The cable is also inspected for wear and replaced if necessary.
Shift lever position indicator in the instrument cluster may not illuminate (FMVSS 102) - recall 05V-055
1 matching record
Under certain starting conditions the shift lever position indicator in the instrument panel cluster may not illuminate.
Under certain starting conditions the shift lever position indicator in the instrument panel cluster may not illuminate; on later start-ups the condition may or may not recur.
What to do
- Dealers reprogram the instrument panel cluster.
- Prepare the vehicle for instrument panel cluster (IPC) reprogramming, then program the IPC using TIS data version 2.25.
Purge Solenoid: failed
1 matching record
Aftermarket part (not the vehicle as built): Fram G3727 replacement fuel filter connector - recall 06E-043
No matching record (stated by the technical documents)
The connector on the fuel filter was not manufactured to Honeywell's specification.
As a result, the O-ring may not seat correctly on the fuel line.
What to do
- The part number (G3727), country of origin (Mexico) and the date code (e.g., X60031) are located on the side of the fuel filter.
- Honeywell notifies owners and replaces the fuel filters free of charge.
Hydro-boost brake assist and power steering share one hydraulic supply (four campaigns)
No matching record (stated by the technical documents)
Some vehicles were built with an out-of-specification hydro-boost housing relief valve bore.
The hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
What to do
- Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.
- To tell whether a 670 gear box is fitted, inspect the mounting bolts that attach the stub shaft housing; a 670 gear box has only 3 mounting bolts.
- The PI document instructed technicians to diagnose the vehicle using the Power Steering Test Procedures if an owner complained about difficulty steering during "parking lot type maneuvers"; if the vehicle passed this test, no work was required, as GM viewed this as a normal phenomenon.
- Dealers replace the hydro-boost relief valve.

Conversion equipment (not the vehicle as built): Southern Comfort running board courtesy lights overheating - recall 03V-094
No matching record (stated by the technical documents)
The courtesy light or lights might overheat when the wire harness is exposed to excessive moisture and road salt.
What to do
- Dealers replace the wiring harness on these running boards.
