My 2008 avalanche with 72,000 miles on it, is completely rotting away underneath. I've 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.

Twice in a row when filling, gas backed up and spilled. I attributed this to a faulty pump. Later that evening while parked I discovered a fuel leak. I took it to a mechanic who discovered the fuel pump had rusted and corroded away. The next day I began my drive home from florida to chicago. I made it about 200 miles before we changed drivers, and discovered the truck had started leaking fuel again. Thankfully, we made it safely to a repair shop (a national company this time). They diagnosed it as the fuel tank, located a replacement tank, and I was under way. I did make it home to chicago, smelling gas the wholeway, but not seeing a significant leak (probably due to the constant driving, I did keep checking) until I was almost home. I made it home, and took the car to a local shop. The diagnosed it as fuel lines, which had rusted and corroded. I picked up my truck last night, drove it to work today, then drove it right back to the mechanic, since it was leaking gas again. I have spent over $1500 so far in labor and parts, lost almost a full tank of gas with all the tank drops, and still do not have my truck back. Im pretty sure my, mechanic is ready to give up.

Rear hydraulic brake lines rotted and leaked fluid causing loss of braking. Last year I had to have the rear brake calipers replaced due to excessive rust and rot. The mechanic performing current repairs stats that the front hydraulic lines are rusting and will have to be replaced soon. The front calipers have rotted out bleeder valves. The front calipers will have to be replaced as a result when the front hydraulic lines are replaced. Check engine light was diagnosed to an evaporative emissions system leak. The leak was traced to a damaged plastic fitting connected to the fuel pump at the top of the fuel tank. The fuel pump metal was rotted causing the joint to expand damaging the fitting and causing the leak. I do not trailer a boat and the truck has never been immersed in salt water. I have been driving for over 40 years and have never had this amount of undercarriage rust and metal damage on any vehicle I have owned with many more miles and years of service.
