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.

problem #2

Oct 192015


  • 124,000 miles
Cylinder heads cracked due to poor casting (known issue by GM). This led to coolant in the engine causing damage to lifters. Expected cost to fix is approximately $1,500 in parts up to $4,000 in labor.

problem #1

Dec 222012

Avalanche 8-cyl

  • 96,316 miles
On 12/22/12 @ 5pm- shortly after entering onto the freeway, I started losing power. I didn't get higher than 50 mph before the RPM started increasing & my speed started decreasing. I got off the freeway, at the first exit, approximately 2mins after the beginning of the loss of power. Found a mechanic that was just closing his shop & asked him to give a quick check too see if I could continue my drive home, 32mins away. The mechanic checked under the hood & under the bottom & guesstimated the problem to be the flywheel. The mechanic also recommended no driving til repaired. I got my Avalanche towed home that first night. I towed it to my local auto repair shop on 12/24/12, to get a full diagnostic. I was advised by my local mechanic that my 2005 Avalanche w/ 96319 mis, needs a new transmission. My local mechanic advised it may still be under warranty due to mileage, but I have since found out the warranty is 5yr/100000mi. GM is aware of premature transmission failure on the Avalanche, but is not fixing it for the consumer. Something needs to be done to protect the consumer!
