Chevy Colorado and GMC Canyon Engine Problems



  • I have the same engine and it's in the dealership right now. I have 80000 miles (95% freeway)and the check engine light came. They diagnosed and I was informed that it needs a new head. Two days before, my friend who I pushed to buy the same model brought the truck in and was diagnosed with the same problem only her's has 35000 miles on it. I went to check on my truck and found out that there was another Colorado that has the same problem. I called GM and was informed that since I have 80000 miles on it, there is a slim chance that they will cover the expenses. But I will fight them. It will cost me $4000.00 to fix the problem and that's a lot of money.
  • :mad: Well my truck has been at the dealer for 3 weeks now waiting for the head, with no set date for arrival of the part. My service advisor told me that 4 more canyons came in with the same problem these past 2 weeks. I'm so glad I didn't recommend this piece of GM crap to any of my friends. I use this truck for work so this has been a huge inconvenience to my business, having to use my 2006 civic to haul around supplies.
  • Good for you. Now I'm a bit embarassed when I see my friend. I am now using my 87 Toyota P/U 4 cyl, with 250,000 miles on it. Never burns oil, runs good and I get better mileage.
    As soon as the Colorado is repaired, I am trading it with either a Frontier or Tacoma.
    I thought that 5 cyl technology came from the Europeans, BMW, Mercedes and Volvo, then the Colorado would be on the same plain but as you said it is a piece of crap!
  • Well it's been 3 and a half weeks and I just got back my canyon from the dealer. They replaced the head and some other parts and warranty covered the expenses. The truck is not the same. The check engine light is off but it doesn't have the same acceleration and response as before. The engine sounds horrible. Well I sold it to Carmax about 2 hrs after i got it back from the dealer. They actually gave me $11500 for it, I was pleasantly suprised by the amount. I am so glad I got that liability of my back. I can't imagine paying 4k to repair a truck that i still owe 10k on.
  • :mad: My Colorado is still in the shop; it's been 4 weeks now and they still don't have a shipping date :mad: ! One major change, they did finally cough up with a rental (on their dime) until they get my truck done. It is my intention to ensure everyone I know NOT to waste their money on a Colorado. I am thankful I am not having to pay for the repair, like stated earlier, the cost is around $4100.
  • Mine is going on its third week. They said that it will take another week for the head to arrive. Meantime, I'm using a rental too.

    Thanks for the info about the rental.

    I wrote GM a letter of complaint. I also spoke to the General Manager of the dealership here told him about my situation. I hope he can do something to get GM to pay for the repair.
    I am thinking of trading it even at this stage. I am not sure if I'm going to get another Chevy.

    I purchased my 06 reg cab 4wd canyon in December. This is my first Truck and I was not sure what to expect. The Canyon has good looks and drives nice,(or at least I think)so I purchased one.
    I had the Truck 2 days and as I was driving on the highway and the 4wd L light started to flash. I thought since the location of the 4wd L button is relatively close to the radio that maybe I hit it while adjusting the radio. I pull off the highway and turn the truck off and the light reset s.
    The next day (day 3 after buying the truck) the 4wd L light begins to flash again after driving on the highway for about 40 miles. I then drive to the dealer and talk to a service tech, while talking to the tech in my truck the engine light comes on. They tell me to bring it back the following monday.
    I bring the truck back and leave it with them all day. I pick it up that evening and the dealer informs me that the 4x4 TCCM and the ECM are bad and need to replaced. The dealer orders the parts but cant get them until after the New Year. So they rest the engine light and tell me to make sure I use gas from a high volume gas station to prevent the chance it was bad gas. So I accept this and take the truck, about 3 days later we had a unusually warm day so I decide to run the AC only to find it does not work. I took the truck back to the dealer after the parts can in and informed them the AC did not work and left it with all day again. I come back and pick up the truck and they say it is fixed so I get in and drive away.
    One week later while driving to go skiing the 4wd L light starts flashing again, needless to say Im starting to get irrated now. I take sharp turn and found a atv trail dropped the truck into 4wd L and start flinging mud around and climbing hills I thought if it was going to break I was going to break it now. After I had my fun and got out my frustration I got back on the road and would you believe that this particular problem is gone now(go figure).
    Now three weeks later the engine light has come back on. I took it back to the dealer and kept it for a day and told me that it was a misfire code PO300 they rest and said that there is bulletin found Doc#1885534 (which I cant find) and they open a track case #9370405 for my vehicle. The dealer told me to monitor the truck and again told me to use good regular fuel. I had the truck back a whole day and the engine light came on again. Im going back to the dealer tomorrow and see what they say now. Has anyone else had anything close to these problems or is just my luck to pick a dud for a truck.

    It all started with the eng service lite,It a 05 canyon crew sle with 63k. The dealer said it needed a head that was 5 weeks ago. I did have warr. In witch I think is only helping with the rental (5) days the truck sat the rest of the time and I used a spare at work until the head came in. (1000 back orders in Canada) there is a service note on the motor and all involved should push your dealer about it. Hope you got it serviced at the dealer. Its been in for 9 days and I thought I was getting it back fri. but the crank seal started to leak thats because they dropped the timing chain and had to take the front cover off. I hope to get it back at noon today. More to tell if interested. Overall love the truck.

    Well it looks like the tech at the dealer has found the problem to be the valve springs and is ordering a new head as well. They were able to find the problem doing a leak down test on the engine which found 3 leaks in the engine. So this is a old problem from 04-06 Canyon and Colorado trucks.
  • Finally got word from the dealership and GM is taking care of everything including my car rental. I did a lot of arguing, about two weeks, but it paid off. So for those of you who are still having problems with GM, don't lose heart. I think they're finally realizing that this is not an isolated case. So keep on pounding at GM's doors. Good Luck!

    My check engine light came on in my 06 Colorado Crew Cab. Its a 5 cylinder auto z85 with 11,000 miles on it. The dealer told me it needs a cylinder head and that it's going to be a few weeks before the parts are in. But they told me that the truck is driveable and they gave it back to me and told me to just keep driving it until they get the parts in. Is this normal? Should I really keep driving it in it's condition?
  • When I brought in my 05 Colorado it had 82,000 miles and the service tech told me not to drive it. He said it could do more harm to the engine. So, they gave me a rental. It has bween at the dealer for 3 weeks now. No word from them yet.
  • I thought that the head problems were fixed by the time the 05 came out but from what I read there is still problems with 06 trucks also. I have a 2004 with 46k and I am worried now more than ever. What go`s wrong with the head that causes the whole head to have to be replaced? I love my truck and hate to have trade it for something else.
  • :) I got my 2004 back Friday! The head arrived Thursday and the shop got to work. In all honesty, the truck runs good, the engine sounds good, and I am happy about the results.

    However, after saying that, it is still inconceivable to me that any GM dealership would keep a vehicle for a month (I turned over my keys on January 10th and the work was finished on February 9th) without the slightest consideration for the customer. This engine problem is not an isolated case, I was informed that GM was producing 11,000 heads for just this reason. GM, through their dealerships, needs to be proactive with their customers and immediately offer a rental, tell the customer the truth about the delay time, and go that extra distance to harbor a good relationship.

    I expect to read more about the problems people are having with their GM product and very little about how well they are being treated. Please prove me wrong!

    Now I am worried, has Chevy taken everyone's truck that had this problem? Am I the only one that they told it's still driveable and gave it back?
    I am still waiting on the parts but I am driving my truck as little as possible because I am afraid that I might do more damage to the engine.
    I am worried that the only reason they gave it back is becasue they don't want to spring for a rental.

    Was anyone else on this forum forced to keep their truck until the parts were in at the dealer?

    My service advisor did say it will do no harm to drive it as it's only a misfire and they would be on the hook if it caused other problems.
  • I talked at length to a Chevy tech about drive-ablility with the indicated check engine light. His input was that is will not do any damage to the engine, at worse the expected indications would be one less cylinder firing. And that is if the valve could not seat at all. At that time the engine would run rough, probably real rough, but it was still safe to drive.

    One of the reasons Chevy is taking back the trucks deals with some warranty coverages. At least in my case, the warranty policy would not cover the repair if the indications were false. The only way to check this is to remove the head and do a visual inspection. Once the head is removed, you are half way through the labor for the total job. The long time delay seemed to be centered around GM gearing up the lines to produce the heads.

    I was told that GM produced around 11,000 heads. If they weren't all spoken for, the wait time sould be greatly reduced. At lease, I hope for your sake this is the case. As far as the rental goes, it was better for them to supply a rental than to have me discussing, quite loudly at times, their lack of concern for a paying customer. It worked for me this time. I don't think I will be as lucky the next time.

    Thanks for the reply, it puts my mind at ease. I just hope it gets fixed right and I don't end up with more problems down the road becasue of it. So far I have really enjoyed this truck, other than this and the brake-relay recall, its been good.
    After reading Car and Driver's long-term wrap up on the Tacoma, and then reading similar problems in Motor Trend with their long term Tacoma, I'm definately glad I got the Colorado. - -long-bed.html

    They called me Friday and told me the parts were in, so I dropped off my truck. Apparently when GM covers a rental car they only let you hace a GM vehicle (I guess they don't want you driving a competitors car) Anyways, the only thing left on the lot was an 07 Yukon, so I got to drive around in style for a few day.
    My truck is now finished, I picked it up on Tuesday. They said they haven't had any come back yet, so it's definately fixed. I asked them how many of these they have done? They said about 10. (and this dealer is one of the smaller dealers in SOCAL) so there are definately alot of Colorados with this problem.
    Anyways, if you never hear from me again it's because everything is good and the truck is fine.
    Thank you everybody for your help.
  • I have an 06 Canyon crew cab, 13000 miles and 6 months old. Rough idle and check engine light comes on, dealer replaced a fuel injector and says head needs replaced. At 1500 miles needed an alignment, then brake light switch, now this. In 6 months this truck has spent more time in the shop than my previous 3 Ford Rangers accumulated in 10 years of driving. My nephew told me GMC means Great Mounds of Crap. So far they have been giving me a car to drive when the truck is in the shop, so I am out my time which makes a dent in the paycheck.
