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...

Colorado "head" game by febrile

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.

"I'm rather curious if there's a common thread"
That's an interesting question, I know mine was replaced early less than 12,000 miles on the truck and I baby it. I don't drive like a race car, and I change the oil every 3,000 miles.
I do however haul a 3,000lbs trailer every once and awhile, but only a couple miles here and there.

Valve spring and head issues by ron_m

My 80 yr. old father purchased an '07 Canyon Friday afternoon. After reading
several posts in this thread
I am now concerned about his PU truck purchasing
decision. I sure do hope that it is true that GM has
switched over to a different head design for the '07
model Canyon/Colorado; and that the valve spring and
head issues reported here are now history.
 
I'm also in the market for a new PU truck and have
driven the Canyon and Nissan Frontier both. My interest
lies in a crew cab, short box 4X4. I'd like to purchase
a domestic PU truck, but after reading about how many of
you guys have experienced engine problems with your
Colorado/Canyon PU trucks, I am starting to seriously
second guess myself on a potential Canyon purchase. Even
with a 100,000 mile power and drivetrain warranty, I
simply do NOT want to go through a lot of inconvenience
with reliability issues. Especially with a brand new truck.

Just remember most of the people here are here because they have had some problems or like you are looking for a new vehicle. This is a good place to find out what can go wrong with your purchase but again the problem vehicles on the road would be in my guess less than 5%. ALL VEHICLES have problems sometime before they die you are just hoping it's not while you own it. I have a 04 crew 4 X 4 and have not experienced any problems like have been displayed here. Only problem I have had with mine was oxigen sensor went south but all that did was put on the check engine light. It didn't drive or run any differently as far as I could tell. Don't let what you read here bother you, if that is what you want then go for it. If you plan on keeping it I would buy the extended warranty and that goes for any truck, american or foreign as just one repair can use up what you paid for the warranty. Some dealers are now charging $125 per hour or even more to work on your vehicle and they have got so high tech that your neighborhood garage can no longer work on them.

I don't know why ya let him make such a mistake....just to save a couple of $100 bucks!!??
All the warranty in the world is useless after ya start having the head aches of having to keep going back to a dealer....unless ya just like to hang out there.
