On the 2002-2006 Chevrolet Avalanche, 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 likely in environmentally corrosive areas where road salt deteriorates the ABS wheel speed sensor wiring and tone rings. This creates a safety hazard as the vehicle takes longer to stop than expected during routine braking.

This issue also affects: Chrysler 300, Ford Transit Connect, GMC Sierra 1500

Common Symptoms

ABS activates during normal low-speed braking
Pulsating brake pedal when it should not be pulsating
Increased stopping distances during routine stops
ABS warning light illuminated on dashboard
Grinding or buzzing noise from brakes during normal stops

How to Fix

Inspect and clean all four ABS wheel speed sensors and tone rings. Replace corroded sensor wiring or connectors. If the ABS module itself is faulty, replacement costs $600-$1,200. Applying dielectric grease to sensor connectors during brake service can prevent corrosion. In some cases, ABS module reprogramming at the dealer resolves the issue.

Parts and tips from 220+ owners who fixed this issue

TipClean the ABS wheel speed sensors and tone rings during every brake job. Corrosion on these components is the most common cause of unwanted ABS activation. Apply dielectric grease to all sensor connectors to prevent future corrosion. This is a $20 preventive measure that can save $1,000+ in ABS module replacement

On the 2002-2006 Chevrolet Avalanche, 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 holding the cladding in place become brittle and break, causing panels to loosen or detach. The cladding issues are cosmetic but affect vehicle appearance and can expose underlying metal to corrosion.

Common Symptoms

Gray plastic cladding turning white or chalky
Cracks forming in cladding panels
Cladding panels loose or rattling
Missing cladding clips causing gaps
Underlying metal visible where cladding has pulled away

How to Fix

Restore faded cladding with dedicated plastic restorer products (Solution Finish, Cerakote Trim Coat). Replace broken clips with new GM clips or aftermarket equivalents. For severely damaged cladding, replacement panels are available from aftermarket suppliers. Some owners choose to paint the cladding to match the body color for a permanent solution ($500-$1,500 for professional paint).

What Owners Are Using

Parts and tips from 400+ owners who fixed this issue

TipSolution Finish or Cerakote Trim Coat are the best products for restoring faded Avalanche cladding. Apply every 6-12 months to maintain appearance. For a permanent fix, many owners paint the cladding to body color - this eliminates the fading issue entirely and modernizes the look
