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

The frame of the truck rotted and is no longer driveable without a chance of an accident. The pa inspection is about to run out also and will not pass inpection. I bought this truck used and just paid it off and was hoping I was clear of any vehicle payments. At this point there is no way I will even get close to what I paid for it as it is only good for scrap. I agree with another post I saw on here that said if Toyota had to recall their vehicles for the same reason then why does GM not have to do the same thing? it only seems right. I know they have heard of this issue but are just trying to brush it under the rug hoping it doesn't come up. Hoping you have our back on this with trying to protect the consumer.

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.

The contact owns a 2004 Chevrolet Colorado. The contact discovered that the undercarriage of the vehicle was severely corroded. The contact expressed concern that the corrosion centered around the suspension and subframe spring mounts. The vehicle was not taken to be diagnosed by a dealer or independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 134,000.

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.

Frame is broken on both rails between cab and box, also cracked above rear leaf spring purch, wherever welds are present frame rusted into

- Three Rivers, MI, USA

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.

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. I am not a forum member, nor do I believe in "internet shaming" I am loyal GM customer, but I it is very disappointing that I have a relatively low mileage truck with a great drive train, and no exterior rust that is completely unsafe and unusable.it sounds like a similar issue that Toyota had ive had and do currently have older GM vehicles with more miles and the frames are in excellent shape. Is GM/Chevrolet doing anything to help consumers?

- Knox, ME, USA

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 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.

- Horseheads, NY, USA

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.

While traveling at appx 50 mph, vehicles suffered catastrophic seizure of the left front wheel bearing assembly causing the wheel to lock up and spinning the vehicle appx 180 degrees in the highway. No collision resulted, and there was no damage.

- Waldron, AR, USA

Todays date is 04/20/2013 #1- wheel alignment front to back, where rear passenger side tire sticks out from body. #2- this is my forth set of tires because of alignment problems. #3- rear tail lights seem to be burned out, they are not it a poor socket problem, I lube with electrical grease. I can't believe that they are introducing the market with making more of the problems for the new line 2014 and beyond. This is the worst Chevrolet I ever owned the 2004 Colorado. I have owned 14 Chevy, will Chevy be in my future?

Subsequently incident repeated on two occasions, ca. 11/15/11 and ca. 12/16/11 after starting into a turn at low speed, perhaps with slight braking. No loss of control. Checked at dealership 2/14/2012 with no cause determined. Later same day, failure occurred again, with same symptoms: Low speed with turn and perhaps slight braking. No loss of control. Diagnosis suggested faulty hubs again. Resolution pending.

The first and ongoing problem grinding in front left, driver, side wheel area. Many attempts have been made to fix this problem, they started out changing the whole front end, along with alignments, after some adjusting the problem will seem to go away only to return with in 2 months second, tires worn from inside out alignment, new tires, I was told one reason was the truck was dirty. I do not feel this is a reason for tire wear. New tires same problem. Third, truck not engaging when shifted into gear. This is on going, we have taken it in many times, the modular for the 2-4H-4L drive was changed, still have problem, they claim can not fix if it does not happen with them, , I video taped it, they will not look at video. Problem is intermittently, and have been asked to do different things to the truck when it happens, the problem is happening more often now, the problem seems to be growing. And still no answer to this or other problems, the dealer should have took back the truck and replaced it, if they can not be fixed.

I noticed uneven wear on my tires. So, I stopped at a garage and I was told the tires were under inflated even though I had the tires at the recommending psi. I put the psi in that the technician recommended and the problem seemed to go away. I went in to have a routine oil change done at a local shop a year after this, and I needed to replace all 4 tires. They had worn down on the inside tread to the steel within only 26K miles. The vehicle has been driven conservatively, and mostly highway miles by my wife. So I put four new tires and had an alignment.

- Batavia, NY, USA

Vehicle causing excessive tread wear on inside of tire, exists on multiple sets of tires. Tread worn completely through, exposing inner layers of tire. If not noticed when it was there was a risk of complete failure for all 4 tires. Manufacturer refused to make adjustments to vehicle after first 4 tires failed (30K miles), continues to refuse service after next 4 showing same problem (15K miles).

I bought a 2004 Colorado in March of that year, on Dec. 31st 2004 I had to replace the two front tires at my expense. They had worn from the inside out the tires had 23,000 +miles on them. I complained to the dealer and they told me that there was not anything wrong. In March 2005 I had to bring it in for the same thing with less miles on those tires 17,000 miles and they still insist that there is nothing wrong. I soon will have to replace these tires before winter. The dealer tells me tires need to be rotated more often. I've owned other S-10 models with over 250,000 and haven't had the problems I've had with this type of problems. I did have other problems with this vehicle from door wiring, replacement of O2 sensor, front axle seal driver side replace, headlights, fog lights and tail lights all have been replaced within the first 20,000 miles.
