Mechanic had the truck on the lift raised up to check the brakes for squeaking and while under the truck the mechanic inspected the frame because he noticed a lot of rust and called me to come look at it and pointed out that the frame has rotted to the point that he should not be driven and could break in half and cause major problems for the safety of the occupants and other drivers on the road. I looked up online if other Colorado owners had the same issue and others have the same problem. I'm am forced to junk this vehicle even though the rest of the truck is in very good condition
I currently own a 2004 Chevrolet Colorado miles are 107,650. My truck is in very good to excellent shape, I take pride in my vehicles. The issue I have is my frame is rotten and cracked at the leaf spring hangers, much to my surprise when I jacked my truck up to change over tires and the rear axle stayed on the ground. Im very grateful we caught this before the right side broke away like the left side did. I do live in maine and they use products on the roads for ice, but my fuel and brake lines are in very good serviceable condition, as is most everything under the truck including the bed. I have been looking for guidance and stumbled onto some "forums" that state first gen Colorado this is common. …
Tl* the contact owns a 2004 Chevrolet Colorado. While driving various speeds, a crunch noise was coming from the rear of the vehicle. Each time the vehicle drove over a bump in the road, the noise grew louder. The vehicle was not taken to the dealer. The vehicle was taken to an independent mechanic where it was diagnosed that the frame had corroded through and the suspension was detached. The vehicle was not repaired. The manufacturer informed the contact that the vehicle was out of warranty and did not offer further assistance. The approximate failure mileage was 124,300.
Vehicle has 96,800 miles, and the frame has completely rusted through causing the rear suspension to detach from the frame, as well as the bed to detach from the frame. Vehicle is no longer able to be put on lift to have tires rotated as the frame disintegrates upon contact. This is a very well known problem, and I am curious why the federal government has not forced GM to recall these vehicles like Toyota was forced to do with their identical situation. Do your jobs, and hold these corporations accountable for cheap workmanship.
I went to install brakes when the mechanic noticed the jounce bumber missing, but when he looked closer he noticed it was rotted. The jounce buper bracket is part of the frame and it completely rotted out. I called GM and they inspected it and they said there is nothing they could do. I said Toyota replaced all the chasis rotting out in the state of massachusetts, this would be the same the salt brine is rooting out frames and this vehicle is no longer safe. They will not even buy it back. I need your help.

The truck has a very rotted frame on it. Seems to be of poor quality and with only120,000 miles and the body is in super condition this should not be happening.. Is there any thing to be done,will Chevrolet do anything at all to help? Are we all stuck with this problem as others on line have complained of this. Thanks.
The frame is rotting out--I've had to have it repaired--welded--each of the last three years after failing inspection or being told it would. Suspension attachment areas, under and around shackles, cab mounts, long sections of primary frame from front to rear.
Severe rust / rot on the frame both on the main frame as well as the front frame work to the point that a salvage yard declared it unsafe to drive. Discovered when I had to replace the rear differential which also snapped due to rust.
