My dad bought his 2004 colorado 3.5 4x4 new from Valley Chevrolet in Wilkes-barre, PA. He has been having a misfire issue, also throwing codes. He had it to the dealer but it did not throw a code for them. It idled rough but said since no code was thrown, they could not diagnose. Truck had approx 60K on it. Now it has just over 80k and he had it to local garage. They swapped coil and problem stayed with cyl 2 i believe. The plugs were changed and several tanks of fuel were through it. He doesn't have the recepit from his vist to the dealer, but does the dealer have to honor warranty since it was in there previously for same issue?
We just saw all the issues others are having concerning the exhaust valves and seals.

Good morning, Mike,
This is a very good and fair question. For the 2004 model year, Chevrolet vehicles had the Bumper to Bumper Limited Warranty for the first 3 years or 36,000 miles that the vehicle was in service. The Powertrain Limited Warranty wasn't applied to Chevrolets (and other brands) until model year 2007. As the vehicle was out of warranty on mileage at the initial visit, and presumably time, a warranty repair isn't likely. I know this isn't necessarily the answer you were hoping to hear, and I apologize.
However, if work were to be performed at one of our dealerships, or if parts were to be purchased from us for repair elsewhere, there are warranties that would come into effect. If you would like more information on that, please let me know!
All the best,
GM Customer Service

I Have a 2005 GMC Canyon, Love the truck over all however I Have a Reduce power fault and a Traction control fault light coming on. I am told it is my PCM, I was also told that Part is covered under warranty for 8 years or 80,000 miles is that correct?
Thank you in advance

Good morning Pam,
The Federal Emission Performance Warranty on a 2005 GMC is contingent upon whether or not an EPA-approved inspection and maintenance inspection is enforced in your area. We would be happy to check into the coverage on your vehicle (sometimes can depend upon where the vehicle was originally sold) if you were to send us an email with the last 8 digits of your VIN.

Had similair issues. Traced it to the throttle body. What I learned is the Colorado intake system is very sensitive to any kind of debris build up in the throttle body. Now I just repace the throttle body every 50K miles and it seems to take care of that and other issues. Part is about $280. Make sure to buy a new "o" ring gasket for it.

#627 of 707 2004 GMC Canyon 4x4 "Reduced Power" setting code P0601
Feb 06, 2012 (9:49 am)
I am new to the forums. My canyon started this saturday afternoon. Let it cool down drive a quarter mile and the same thing happens. Each time I cleared the code using OBDII and let it set. Eventually the canyon returned home powered by a flatbed with $190. The dealerships can't connect to the recall database provided by GM until 13 Feb. With two people who work and only one GMC running, I need help and/or advice.

I seem to be having the same issue with my '04 Canyon (2.8 4 cyl) as I am coming up on 85,000 miles. Some mornings it won't start, just starter grinds and grinds; I give up and take the other car. This morning truck did start, at lunch time did start to let me leave parking garage, 15 min later would NOT start after I had picked up lunch. Called AAA for tow, tried one last time 5 min after non-start and it DID fire up this time, took to dealership anyway. I had never got any amber check engine lights/codes.
They could not replicate problem, fuel pump pressure was good, fuel filter dirty enough to warrant changing. In all their fiddlin with it they got one code once (did they say crank sensor?). They took off an intake hose and shined light in to TBI and showed me carbon build-up at top, and while not claiming that was the root of problem, are recommending fuel injection system cleaning for a couple hundred bucks and I will probably authorize that. Someone online here mentioned AC connection to all this ... I do believe mine was off the first two times today when it stared, and that I had turned it on at mid-day before it did not start. This is where I am at this point.
