My 2008 Avalanche with 72,000 miles on it, is completely rotting away underneath. Ive had to replace many parts, shocks, autoride compressor, fuel pump module, had body rust repaired, have had 3 door handles fall right off. . Last 2 mechanics told me that all parts located underneath truck are rotting away and that I need to get rid of truck because it is not worth repairing. I have tried to work with gm but they claim that its normal wear and tear. Paid 30k for truck Dec 2011. Have membership to car wash, and keep it very clean. Undercarriage included. Cant get my service suspension light to shut off, even the dealer cant. This truck should not be rotting away the way it is. . Please help.

I purchased a new 2008 chevy Avalanche and, shortly after the first year of ownership, I noticed that the front tires were wearing on the inside. I had the vehicle alignment checked regularly and the alignment was within specs and the suspension was without defect. This was reported to the dealership, to the customer assistance department at Chevrolet and nothing could be found that was a cause for this condition. Recently, I took the vehicle back again to the dealer to check its suspension and alignment and it was clear that the front tires were cupping on the inside. The dealer shared a TSB with me indicating that this condition was normal. I contacted the customer assistance center again and they could not provide a solution or any accommodation for this. Something is wrong with the vehicle design that would cause this premature tire failure but Chevrolet is denying this. Please help as I have found this condition to adversely affect vehicle stability.
