A RECALL WAS IMPLEMENTED IN 2008 TO ADD A FUSE TO THE CONTROL CIRCUIT HARNESS TO ADDRESS THE POTENTIAL CONSEQUENCES OF A PRINTED CIRCUIT BOARD (PCB) ELECTRICAL SHORT. HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.

What is the 2002-2008 Chevrolet Avalanche 4L60E Transmission 3-4 Clutch Failure / Slipping?
Avalanches equipped with the 4L60E automatic commonly lose 3rd and 4th gear due to 3-4 clutch pack burnout, a known factory weak point. The long fluid circuit feeding the 3-4 clutch leaks at the input housing (steel shaft galls the aluminum bore) and at the 2-4 servo, so the clut… Repairs typically run $1,500-$3,500. Severity: high.
What is the 2002 Chevrolet Avalanche Unwanted Low-Speed ABS Activation (Corrosion) - Recall 05V379?
Corrosion of the front wheel-bearing hub can contaminate/affect the ABS tone ring and wheel speed sensor, causing unwanted ABS activation when braking at low speeds (roughly 3-10 mph). This extends low-speed stopping distance and pulses the pedal unexpectedly. GM issued recall 05… Repairs typically run $150-$500. Severity: high.
What is the 2002-2003 Chevrolet Avalanche Brake Line Corrosion (Salt-Belt Vehicles)?
Early Avalanches (2002-2003 model years of the GMT800 generation) are subject to steel brake line corrosion, especially in road-salt regions where flaking/scaling pipes can rupture and cause sudden loss of brake pressure. NHTSA investigated roughly 2 million 1999-2003 GM full-siz… Repairs typically run $300-$1,200. Severity: high.
What is the 2002-2006 Chevrolet Avalanche Unwanted ABS Activation Increasing Stopping Distance?
First-generation Avalanches (2002-2006) can experience unwanted ABS activation during normal low-speed braking. The antilock brake system activates inappropriately, causing a pulsating brake pedal and increased stopping distances when it should not be engaging. The issue is more… Repairs typically run $100-$1,200. Severity: medium.
What is the 2002-2006 Chevrolet Avalanche Body Cladding Fading, Cracking, and Clip Failure?
The first-generation Avalanche (2002-2006) features distinctive gray plastic body cladding that is prone to fading, cracking, and clip failure. The unpainted plastic panels that encircle the body deteriorate from UV exposure, turning chalky white and developing cracks. The clips… Repairs typically run $20-$1,500. Severity: low.
What is the 2002-2006 Chevrolet Avalanche Erratic Fuel Gauge / Fuel Level Sensor Failure?
The in-tank fuel level sending unit on GMT800 Avalanches wears out, producing erratic readings: the gauge sticks on full or empty, drops suddenly, or reads inaccurately. The cause is wear/contamination of the resistive card the sender wiper rides on, leading to intermittent conta… Repairs typically run $250-$600. Severity: low.
What is the 2002-2006 Chevrolet Avalanche HVAC Blend Door / Mode Actuator Failure?
The plastic HVAC temperature (blend) and air-delivery (mode) door actuators fail commonly on GMT800 Avalanches. Internal plastic gears strip or position sensors wear out, producing a repetitive clicking/ticking behind the dash and loss of temperature or vent control. On dual-zone… Repairs typically run $100-$350. Severity: low.
