Rear leaf spring mounts and frame rusting through causing a safety hazard. Chevrolet doesn't offer a repair part nor does the aftermarket. The internet is ripe with other owners experiencing this or similar issues. The consumer stated there is frame corrosion specifically rear frame shackle mounts and lateral supports. The contact believes that the failure comes from the frame being made with the wrong metal thickness or metal that is not rust-proof. The vehicle was taken to a specialty shop to weld the frame, but the contact believes that is not the best way to fix the issue.

I have a 2006 Colorado 2006 crew cab L-5 engine. I have owned it for 2 1/2 months. It has been to the dealer for 1. rear main bearing seal leak three times. 2. two wheel alignments. 3. auto- transmission cable fell off. This was when I was bringing it in to the dealer for one of the many repairs. 4. it still has to go back for replacing the rear window (on order). This vehicle has been in the shop for 25% of the time I have owned it.
