i would take it to a different dealer to investigate or talk to the manager and have them investigate all GM bulletins regarding this issue. the dealer i took it to is following the protocal of a GM bulletin. my truck is currently being repaired for a similar problem. mine was not as bad as yours. i only had a rough idle and check engine light. i took it in directly to the manager of the dealership and starting working on it at no cost to me even though my warranty was expired. my valve in my 5th cylinder was stuck open causing miss fires.

My 05 Canyon Has Just over 30k miles and did the same thing. I took it into my private mechanic and they found a misfire on the #4 Cyl. GM Had the truck for 2 weeks and did not find the misfire. I took it back and had the GM service notice from my mechanic stapled on the Steering wheel. They require all the valve springs replaced to correct the problem a 6.1 hour job and it requires a special tool that breaks when they try to fix your truck. Still haven't gotten my truck back after 3 weeks now.

I had the valve problem in my '05 Colorado (got it back this time last year). I had about 20k and they replaced the head, which took 3 weeks. I have put another 10k since and the truck has been mostly fine since but I am afraid it will break again and won't be covered. I tried to find out what the problem exactly is and how it was addressed. Like, were there some bad parts? was it a design problem? Whatever it was did they just put the same junk on or was the part/design corrected. The dealer treats you like an idiot and I could not find anyone to give me a straight answer. I bought a second one of these trucks for my father in law and worry if he will have a problem. This is my first american car. I have had Honda and Toyota, mostly Toyota trucks. My last 3 Toyota trucks I put 170K, 230K and 160K on each one and have never had any problems at all. I like the way the Colorado looks and it drives fine for me.

Like others out there my engine has begun its decent. After figuring out what exactly has to be done to fix the misfire ($4400) later, GM is deciding wether or not they want to help. Problem began at 52,000 miles and not being covered by warranty has caused a serious altimatum of wether or not to stick this out. If GM does not pick up the tab then I am swearing off Chevy for the rest of my life. I feel that this is a defect and should be a recalled.
Any advice out there

Learned today my '05 Colorado LS (Z85 4X4 I5 5-speed manual)head has to be replaced. Only 26,000 miles on it. There is no recall, but the dealer gave me a copy of the service bulletin regarding the problem. The new head is supposed to have "hardened" valve seats. Strange that the problem is with cylinder # 4. I saw someone else had a problem with the same one.

My 05 Colorado had 82,000 miles on it and GM covered all the cost including car rental. I spoke to the dealer's general manager and also called GM's customer service. They offered to pay half of the cost first but I told them it was unacceptable. Try to get a hold of the Factory Rep in your area. He can do wonders for you.
I don't have the Colorado anymore. I traded it in with an 07 Silverado LT. They took the Colorado at mid-price value even when it hasn't been worked on yet. I just signed the release the other day. I have who have friends at other GM dealerships and they were able to give me a pretty good number of Colorados that are in their service area with the same problem. I'm pretty sure GM knows how many there are but for you to know, that gives you a little bit of advantage when you talk or write them. (I also wrote a letter of complaint to GM)
Well, good luck and hope you get everything squared away.

Oh, GM is bearing the cost of repairs and providing replacement transportation for this. I have < 26,000 miles. But I am disgruntled with further problems with this truck after going through the arbitration process becuse of a vibration at road speeds. I lost that but got all 4 General Ameritech tires replaced with GoodYears. So far I have had the cruise control switch, the tail light switch and, now, the cylinder head and instrument panel/dome light switch. There is a lot of wind noise at road speeds that they didn't resolve with insulation behind the interior trim. I am really fearful that this truck is going to be a bad lemon. And it's yellow (very) to boot.

I just got my truck back after the head was replaced. it took three weeks. GM covered the costs and a loaner. the dealer did not give me any details of the repair or suggestions on what i should do if it happens again. i am starting to get vibrations at idle and low speeds again. Not alll the time just some of the time. this is the same issues i had before my engine light went on the first time. I think i am going to trade it in...

I'm rather curious if there's a common thread, more that just a Colorado or Canyon truck. In other words, do the symptoms start at a certain mileage, on a truck that has more "city" vs. "highway" miles, on a truck that has it's oil changed at 5000 mile intervals vs. 2000 miles, and other things like that. Anyone care to comment?
I have a 2005 Canyon 4x4, that currently is approaching 18,000 miles. I'd hate to think that I'm driving a "time bomb", that's going to crap out at any minute. This is especially important to me, as my Canyon is a winter vehicle. If I wanted to drive an unreliable car/truck during the winter, I'd go back to an 8-10 year old, $750 "hoopty", like I drove in the winters of years gone by...

I had not noticed a misfire at idle, which they claim is a symptom of this problem, but I have had an intermittent vibration from day one. GM replaced all the tires (Generals were said to cause the vibration) within a couple of weeks of purchase. The misfire came to light because the engine light had come on for a day a couple of times. The code was stored in the computer.
The dealer told me there is no recall for the head problem, but there IS a service bulletin addressing the problem. Others here have indicated that GM is taking care of the problem regardless of warranty standing. That's good to know.
I took Chevrolet Motor Division to arbitration over the vibration, which persists today (26,000 miles), but which the NH arbitration board (3 members) said they could not feel when driving the truck. From the number of posts here, I would say the problem is wide-spread. I am generally not satisfied with my truck.
