Print this page Notes: It didn't take long for the cladding to fade, discolor, and in some cases crack. Cladding is the protective plastic piece that runs along the outside of vehicles, and exposure to both heat and UV rays give the Avalanche's cladding a chalky, faded appearance.

Owners have said the problem is especially bad on the panels near the cargo bed. Eventually, GM agreed to a one-time treatment of ArmorDillo, a protective treatment similar to what you find in any auto shop. Unfortunately, that would only help for 6 months (on average).

Eventually, GM offered another coating solution for owners within the 3 year / 36,000 mile original warranty under TSB:04-08-111-001C.

2005 Chevrolet Avalanche Owner Comments

problem #1

Dec 082007

Avalanche 4WD 8-cyl

  • 36,500 miles


Anytime I turn the air on in my 2005 Chevy Avalanche it makes a high pitch screaming sound. I have had two blower motors installed and it is in need of a third. This sound is still present even after I have had the new motors installed. I have had one mechanic say their is a crack in the plenum box and it would take 11 1/2 hours to repair and cost $ 1700. This is the only quote I have had so far. I have had it at the dealership where I bought it and they never seem to find anything, then again they seldom do anything right.
