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.

Supply and return fuel lines have a flexible, shielded section at the frontmost end... the hoses cross and therefore rub against one another... top hose became worn through, causing copious quantities of fuel to be pumped out onto the cross member and roadway... extreme fire hazard.

I have 2005 Chevrolet Avalanche..I'd been smelling gas everyday I drove the truck for about a week. I left work and made it home one day and gas was leaking all over the drive way. I checked for recalls and there is a recall for the year, make and model, but the recall does not apply to my VIN according to GM. I will need to have the truck towed for repairs because it is not safe to drive to a GM dealership.

I have a 2005 Avalanche that I was driving to work and I started to smell gas in the cab of the truck. When I arrived at work a co worker came over and stated your truck is leaking fluid. I got out of the truck and it was leaking gas all over the ground. I had just filled up the tank and it was a little over 1/4 filled. Upon further inspection after the lines dried I noticed a hole in the fuel lines. It looked like it had rubbed together with another line and causing a hole.

The contact owns a 2005 Chevrolet Avalanche 1500. The contact stated while at a complete stop the check engine warning light illuminated on the instrumental panel. The contact then noticed there was a fuel odor coming from the driver's side door. An authorized dealer stated that the fuel lines were crossed above the catalytic converter causing the them to rub and fuel to leak from the fuel lines. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure and current mileages were 132,000. Updated 05/31/12

Driving home I started to smell gas in the cab of the truck. After the truck was parked I found gas on the ground under the engine. When I had a mechanic look at the problem he found that the factory installed fuel lines were touching and had rub a hole in the fuel lines and were leaking gas on the engine also the E85 sensor module was cracked and leaking gas. No fuel line parts were available for the repair. I was told not to use the truck as the leak could cause a fire. This to me is a big problem as their is no warning.

With no warning at all my fuel line began to leak profusely. No sensor warnings/lights at all. Fuel line was leaking a tremendous amount of gas - leaking to the point I was afraid to leave it parked in my driveway near my house or even out on the street (in case someone walked by with a cigarette). I feel this was an extremely dangerous situation. To make matters worse, my truck has been in the shop for over a week and several Chevy dealerships are unable to get the parts from the factory and in some instances are only being told they are "backordered" with no approximate date of availability.

Vehicle would not start unless the key was turned to accessory position for a few seconds. This allowed the fuel filter to pump fuel to the engine. I have read of another individual having the same problem through the internet. I am concerned of other people having the same problem and needing to spend the money to have it fixed or not fixing it. I have had the vehicle checked and the fuel pump was replaced. Fortunately this did not happen while driving, but it seems to be a factory defect that should not have happened. The Chevrolet dealer kept the old part.
