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.

(1) normal driving use - with limited usage of mid gate. (2) while raining water enters the cab through the mid gate, causing the carpet and matting to become soaked with water to the point that water pools on top of the carpet. This more than likely will result in the immediate rusting of the floor and possible growing of mold in the constantly wet carpet and matting. (3)dealership has replaced and seals on several location was well as added additional silicone, although no attempt at repair have been successful in slowing down or stopping the water.

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 18,000 miles
The passlock system that comes on the 2005 Chevy Avalanche can be bypassed by a pin hole in the drivers side key tumbler. Shuts off the system and interior items are accessible to thieves. A alternative security system has to be added to be secure. Chevy doesn't provide this. It has to be aftermarket.
