I recently took my chevrolet colorado in to a chevrolet dealership because my "check engine" light was on. It was diagnosed that a sensor on the gas tank was rusted and needed to be replaced. The service manager admitted this was common for a colorado. Parts were ordered and I was told it would cost about $800 to fix. I brought my truck in a few days later to have the work done. Later that day I was called and asked to come in because they found another problem with my truck that I needed to see. Upon arrival, I was taken out to see my truck on a lift and shown a frame that was completely rusted out. The service manager poked a screwdriver into the frame causing pieces of rust to fall to the floor exposing a hole in the frame. I was also shown where the frame was cracked right under the gas tank. They offered no explanation when I asked why they had not found this problem when they diagnosed the problem with the gas tank. All in this past year a the same dealership, I have had my truck in for new tires and shocks with no mention about my rusted frame. They blamed the rusted frame on the salt brine used on maine roads during the winter months. I was told my truck was pretty much worthless. When I asked why chevrolet didn't built frames to better resist the salt brine they offered no answer. I have taken my truck to multiple car shops where they reported they see this frequently and the only thing I can do is either sell my truck for parts or replace the frame which would cost in excess of $15,000. I can't imagine that my truck is an anomaly and wonder how many other people might be driving a vehicle that looks almost new like my truck does but has a rotted frame. Toyota recalled their tokoma trucks due to this same problem. I am hopeful something can be done. Other than the rotted frame on my truck the rest of the under carriage is pretty much pristine.

For several years I had problems with my engine light, ABS light, and brake light intermittently coming on. When these lights would come on, the antilock brakes would sometimes prematurely engage, dangerously vastly increasing the stopping distance. The vehicle was reacting as if the wheels were locking up, so it was prematurely engaging the antilock. This happened mostly on dry pavement during light breaking. I could feel and hear the antilock pulsing the petal releasing the brake pressure. I couldn't get good braking, even when I pushed the brake pedal to the floor. I took my car to a gm authorized service center/dealership to have it diagnosed and repaired. Despite several trips to the service center, replacing many parts and spending about $2000, the problems continued. It wasn't until after I wrote an angry letter to the dealership management that they replaced a vehicle speed sensor which solved the problem. It was aggravating because I had to pay extra for antilock features when I bought the vehicle. The antilock feature was supposed to improve safety, but ended up being very dangerous. If I would've had a wreck because of the bad brakes, the government would have likely held me liable, for an expensive and dangerous problem that they had created. The government had pressured the automotive industry to include expensive antilock brakes that were complicated, unreliable and dangerous. Intermittently, it would take 3 to 5 times more stopping distance than legacy brakes without antilock. Conventional legacy brakes I could have fixed myself. With antilock brakes; propriety diagnostic equipment was required, so I was dependent on gm authorized service; which was very expensive and did a lousy job.

My check engine light has been coming off and on continuously for the past six months, however it was diagnosed and it wasn't a big problem. Recently, I have been able to unlock my truck using the keyless entry and when I am in the vehicle the doors will not lock with the lock/unlock button on the door. When driving, after accelerating over 20 MPH, the doors use to lock themselves, but now they do not. Normally when I put my truck in park, all the doors will automatically unlock. This has not been happening. I am scared to keep anything in my truck and fear that this might cause more serious problems and expenses. I would like to know if this has been happening with other colorado's? It seems like since I have gotten this vehicle it has been one problem after another and I am very disappointed in chevrolet.

My 2004 chevrolet colorado has had repeated a recurring problem where it will not respond to the throttle at all while driving. In all cases this has happened when the engine is warming up from a complete cold start in the morning. While driving at 45-50 miles per hour the engine will drop to idle speed and there is no response to throttle input. The dealer has had the vehicle in for service on this issue 5 times now and can nothing wrong. There are no codes set in the computer and the check engine light never comes on. The problem will clear itself after 20 to 30 seconds and may not occur again for weeks.

Vehicles check engine light came on then went off after a couple of days. Vehicle idle dropped to 500 rpms. The truck started to act sluggish and acted as if it would shut off at idle. During acceleration the vehicle was again sluggish. Took the truck to a local shop and had the codes run. It came back as an engine low RPM code. I don't recall the actual code number. Had them do a motor vacuum to clean the fuel system and reset code. The check engine light has gone away and has not come back on. Vehicle does from time to time act as it is going to bog down. I thought that I should submit this complaint because it seems there are several others with the same problem.

The check engine light comes on accompanied by an engine misfire due to weak exhaust valve springs which must be replaced. Recently gmc issued a bulletin to their service departments advising mechanics on the issue, and recognizing the problem with the valve springs and how to fix it, but will not acknowledge a manufacturer's defect. According to the bulletin this problem occurs in all chevrolet colorados 2004-2006, gmc canyons 2004-2006, and the hummer h3. The estimated cost of repair is about $2000, quoted by the dealer mechanic. Not only does the check engine light come on and stay on, it also causes the vehicle to stall while in operation. The truck shut down in the middle of the intersection while driving. Additionally you will have difficulty when you start your car, it will misfire and you may have to restart again. This will begin to happen regularly until you diagnose the problem. I went to different dealers to diagnose the problems because different mechanics could not find the problem with the check engine light. The last step was a dealer mechanic that had just received the above mentioned bulletin. They did not fix the problem with the valve springs, instead they reset the computer to stop the check engine light from occurring. The misfiring and stalling continued to happen.

Dt*: the contact stated that while waiting at the traffic light, the engine raced and accelerated as if it was engaging to 50 MPH. In an attempt to prohibit the vehicle from accelerating, the clutch was engaged while depressing the brake pedal. There was also a sulphur smell inside the vehicle. The vehicle was taken to a service dealer who was unwilling to repair the vehicle without a fee. The vehicle was taken to an independent mechanic shop who discovered two trouble codes on the diagnostic computer system. The first was a po300 random misfire code. The second was a p1133 front oxygen sensor slow and switching code. The check engine light from the panel was also constantly illuminated. The issues have gradually worsened since the vehicle was purchased.
