I have not given permission to the dealership service department to start repairs. They told me it was the rear axle or rear end that was damaged beyond repair and must be replaced. I was quoted a repair cost of $2,400 for a used part and $3,000 for a new part. This truck has around 42,000 miles and was purchased June 1, 2003. I have had multiple problems ranging from replacement of cd's to a door window motor problem. I inquired/complained about a noise in the rear end at around 25,000 miles prior to the breakdown. However, they could not find the problem. The tailgate would fall open when locked occasionally, but this was adjusted after taking it back for repair. I have also replaced one hub assembly on the front of the truck at a cost of $250. There is an oil usage problem that requires an additional quart to be added between changes. I personally think that this truck is a lemon and needs to be researched to discern if it has had some previous mechanical problems. Although it was purchased new there is a possibility that it could have had some malfunctions before it was delivered. I misplaced my receipts, and I'm not sure that the service department will give me another copy. However, I will search for them as verification that I took the truck in on several occasions for various and sundry complaints.

Standard tires issued with vehicle were offroad Wrangler hp which have very poor rain handling capabilities. I was not notified of this or given option of switching to highway tires with better rain capability. As a result of the poor control of vehicle in rain, front edge was damaged when entered parking lot and was trying to turn on wet pavement and slid into wall when steering was non-responsive due to tire sliding instead of turning. Speed was less then 10 mph. I have found several articles on internet indicating should either replace those tires or have them "siped" to achieve better control in rain. Since my Avalanche is two wheel drive I never thought much if any about offroad use or that the standard tires would be so geared up for offroad use as to make them handle poorly in rain. Capitol Chevrolet service manager confirmed this information with me. I have 40 years experience driving in the North under all conditions with military and civilian vehicles and have never had this kind of problem before with any vehicle with any kind of tire. Military vehicle tires are very offroad oriented but never had this kind of problem in rain. Thanks.

Front passenger's side tire bubbled on the side. As a result, the consumer continued to rotate tires prematurely. The rotation did not stop the tires from pushing outward in the thread and tire wear. Tread wear was only 27%.

At 7,500 miles I had a blow out on the interstate and had to use my spare, then realized it was a smaller size. I drove to my dealership and they gave me a new tire, and said all of these trucks came with a 16 inch spare. I now have 30,000 miles and now need all new tires. I usually get new tires about every 60,000 miles. I went to the dealership to ask why my tires were wearing so bad and they were not willing to help or discuss this issue.

Passenger tires were supplied with Z71 off-road package. I took these tires off-road, and tore a hole one. All4 tire dealers in montrose, co including the Goodyear dealer, said that these are passenger tires, not off-road tires, and that they will be damaged by taking them off-road in the mountains. Chevy's photos on their web page show the Avalanche fording streams, driving over rocks, and driving in the mountains. The owner's manual discusses driving over rocks and logs, "bouncing the car" and having one or more wheels off the ground as things that might be encountered in "off-road" driving. Still, they deliver the nearly 3-ton truck with passenger tires, not light truck tires. Had I not punctured the dire, but only separated the ply, I could have had a serious accident driving the 400 miles back to my home. The off-road package includes skid plates, heavy duty shocks, a tow package, the all-important Z71 decal, and upgraded tires. It turns out that the upgrade is not to a stronger tire, just a tire that's 1 inch bigger. Still, the implication is that it is suitable for the off-road use described in the owner's manual and in their advertisements. The safety issue is that these tires are more susceptable to damage when used of-road, and subsequent to failure later at high speed when the driver returns to the highway than tires more appropriate to the task, such as a light truck tire.
