2003 Chevrolet Avalanche Owner Comments

problem #5

  • 38,000 miles


2002-2009 Chevrolet Avalanche rear removable window (frame). Lower L/H side (passenger side).plastic frame subject to splitting in time with heat and separates and pulls away exposing tempered glass.tempered glass is now in contact with supporting frame and vulnerable to shattering from road vibration or worse, collision, thus injuring passenger(s) including infants in rear 2003 Avalanche frame began cracking early 2007 and is now has a 1 1/2 inch gap.I along with several thousand owners (research on internet), have brought this matter of defective materials to GM and Chevrolet attention only to be told "sorry it's not covered".I am very disappointed and rather angry that GM would not offer to repair or even replace these obviously defective window frame assemblys.according to my research with other owners up to 2009 model year, this defect still exists and owners that were fortunate to have theirs replaced if still under warranty have reported that the replacement has started cracking just the same! this is proof that GM has done absolutely nothing to improve/replace inferior materials that made this frame.

The plastic cladding on my 2003 Chevrolet Avalanche turned from its original black to a chalky color with streaking. This was not covered under the warranty, according to the dealership. The truck was exposed to normal environmental conditions in Alabama and Tennessee.

Purchased a used 2003 Chevy Avalanche at a dealership in Feb 2006 upon servicing the vehicle two months later was told that the car had extensive under carriage rust. This car originated in Michigan but I am wondering if it was a katrina vehicle during auction? recently had problems with U-joints which had to be replaced. GM mechanic says the rust is extensive and caused this problem it will need a lube kit to re-lube all the mechanics under the truck. None of this under carriage body rust was disclosed to us upon purchasing the vehicle in fact the dealer told us he only gets the best used vehicles. There is also a problem with the steering column which makes a clunking noise when turning the wheel - the mechanic at the GM dealership says this is a know problem.

The rear window was reflective as if it was a mirror. When headlights were on the back window, it reflected forward into the consumer's view. This happened not only when backing out but also when driving. The window surface was very reflective. This was evident in day or night. Had not contacted dealer/ manufacturer.
