Chevy Colorado and GMC Canyon Engine Problems



  • I have a 2004 Colorado, with the 3.5L. When I start the engine it rattles like it has bad rod bearings. Then when your driving under light throttle it makes a similar sound. I all ready know about the cylinder head issue. I had brought it to the dealer multiple times and was told that my head was ok. But the engine was not making these sounds back then. Plus my truck is past their notice limitations. I had heard some time ago that there was an issue with the timing chains and guides. Could this be the rattle issue that I have? Has anyone else had this simular problem? Or should I be looking elsewhere ? Please Help.
  • My 05 3.5L has 90k on it and while i dont have any head issues it has had the supposed timing chain noise for the last 10,000 miles. It runs fine and performance doesn't suffer any but it does get annoying. I found that putting in half a bottle of Lucas synthetic oil stabilizer quites it down some, especially during the winter. If anyone knows of any long term damage from this please share. good luck to all of us!
  • I hate to be the harbinger of doom buddy, but thattruck you have there. Well just make it quiet and run away from it as fast as you can! I had the same pig and traded it in as soon as the warrenty ran out! Problem after problem! The noise your hearing if as you say is the timing chain or the advance/retard mechanisim for the cam, then I`ll tell you if it is not replaced with new parts you will blow the engine. These engines are low clearance heads. They will not clear the piston head when at top dead center. Resulting in vales that are left open whenb the piston comes up will crash threw the tops of the pistons. Let a qualified mechanic look at it. Are you having any codes coming up? Is your engine light flashing on and off by any chance? You can take it to autozone and they will read the codes for you for free. Don`t let them clear it so the dealer or mechanic can see them also. Good luck! I`ve had no problems sense I got rid of mine! :lemon:
  • I bought my truck in 2009 at 60k mi from a Chevrolet dealer and in 2010 had it with a different dealer for a recall. Nobody ever mentioned the worn seal/leak problem. I'm the second owner and obviously never got an extended warranty letter - now in 2013 the truck is at 148k miles and I have the dreaded leakage and rough idling. :sick:
    Of course, GMC - who should have issued a recall for this - Refuses covering the necessary and expensive work. Has anyone gotten this issue covered by GMC/Chevy once the warranty (7 yrs, 100k) had passed? I'm so mad!!!!!!!!! I would have gladly tested the car for any issues earlier, had i known about it. This is consumer fraud! :mad: :lemon:
  • I bought a 2006 3 months ago in great showroom condition with 70k miles loved the truck. after a month of driving it the check engine light came on for random miss fire. took it to my personal mecanic who told me it was due to the head problem.. not a big deal a 3-5 day fix but since it was covered under warrenty to take it to the dealer..well one month later and $1200 for a rental car I did the best thing... traded it for honda. The dealer kept it for 2and 1/2 weeks and finally told me it was fixed I drove it home 2 miles away as soon as it warmed up the check engine light came back on. Took it back they kept it a day told me it was fixed. picked it up it did the same thing again. Took it back to them and they kept it a week and said was my coil, and I owed them $300 for it. Raise cain so they told me it was on them. drove it home and it did it again.. so i took it to my mecanic and ran the code and it pulled 6 new codes again... took back to dealer and they told me it was a concidence and that they where not at fault...keep in mind i drove the truck all of 6 miles in a month. They then said their master mecanic would have to look at it, but i may have to pay...the timing was messed up, the random miss fire still in there, and the computer messed up... I will never buy a chevy again... I grew up driving chevys my first car was a camaro, but now all they care about is how much money they can get out of you.. I guess the dealership figured I was a sucker. however being in the military has taught me a thing or two, and knowing to fix somthing I mess up was part of it. I will stick with a car company who cares about their customers.
  • My truck is in the shop now - engine was leaking passed the valve and needs a new head. GMC is telling me that they are not willing to pay a dime since this could be due to the general wear and tear - yeah right. I'm certain that the truck never had full power and had the leak when I bought it on 2009. GMC also found that the timing chain needs to be replaced - it's too tight. How's that possible, it's a chain?!
    I just hope they are able to fix it. Your story and the multiple check engine lights is just unacceptable - combined mechanic and manufacturing incompetency. :sick:

  • wow that sounds like the run around the dealer gave me. I hope they are able to fix it as well. What upsets me was my had none of the problems except for the head issue when I took it in. And I really doubt its normal wear and tear.
  • Sara, I do no know that there is anything that can be done I had to trade it in because I could not afford another $1000 for a rental car. However the dealer was west chevy in alcoa,tn. I have proof that it did not have the issues before. My personal mecanic is ASC certified, as well as has a shop that is reputable. I just despise how the dealer was so shady. and the truck had 73040 miles
  • New to forum. I have a 2005 Canyon,new head installed at 103,000 miles,I had to pay half for it. Same rough idle came back about 5000 miles later. Dealer said it was a $250 cam sensor. Same idle returned and just kept driving since I could not afford another trip to the dealer.Now have 196000 + miles. Really dont think it is a leaking valve seat issue cause it has not lost power of fuel mileage. Thinking its probrably dirty injectors.

    I have a 2006 colorado that I brought brand new. It has 50,000 miles on it and is piece of junk. Already had to leave it with the dealer for a week due to a factory recall. I have had to replace the tye rods, the power window switch and now it is in the shop having a evap valve replaced and the windshield wiper motor replaced ( another 700 dollars). I knew I should have gotten a Ford.

    Man oh man....I wish I'd known about this site BEFORE I bought my Colorado. I'm from Canada, AND a female and I will NEVER buy another GM. I knew I should have stuck with a Ford. I have had NOTHING but grief with this truck, I think I've replaced every light on the darn thing, it sux 4 litres of oil between the 5000 km oil changes and I dunno if they do this in the states, but every time I took the truck in for warranty work, they charged me $200 deductible! if that isn't a money grab, I dunno what is.....hmmmm....I googled 'colorado using oil' and it gave me this site. I got some good ideas that I'm going to take over to my brothers when he uses his machine to check the codes. I just shake my head.....give me a 1970-80 vehicle any day....all this tech crap is just a money grab! Good luck to you all and thanks for all the tidbits of info...much appreciated.

    We have an 05 Chevy Colorado that just got diagnosed with a cracked head. I see references to a "special warranty" that people have been able to get - what is that? The truck is only driven around town and we are having a hard time believing this has happened. Any info is greatly appreciated!

    Unfortunately, a low mileage, well-maintained S10 pick up would have been a better choice. Good luck with your vehicle.
  • I bought a 2006 Chevy Colorado in November with 60k miles. After approximately 2 months of the check engine light came with code P0305; the fuel mileage dropped from 19.5 mpg to 17 mpg. After changing ALL the spark plugs, the truck seems to run worse. I do not want to have to change all the coil packs at $75 each. Has anyone had this issue and if so did you find the solution to the problem?

    It may just be time to go back to a Nissan, I never had a problem with them.

    Thanks in Advance
  • This is exactly how our valve leakage problem started. Replacing the spark plugs and coil packs will work for a little but after a while our check engine light came on again. Take your truck to the GMC dealer and have it tested for leaking valves.
    If you have less than 100k miles on your truck, GMC will do it for free based on the extended warranty.

    Have 05 Canyon, it low idle or sometimes the idle speed will hunt! Read the code @ Auto Zone and said vacuum leak, where might it be? Thankx for your help
  • 2008 gmc canyon, 4 cyl, 80k miles. Mine knocks when it's cold. When I was a little kid, my dad had a chevy nova that knocked all the time and it ran better on it's way to the junk yard than my canyon does now. It knocks and sputters unless I let it run for 10 minutes before I drive it. Everyone makes fun of me for it. I mentioned this to service departments at wright gmc in wexford, pa and northstar gmc in zelienople while it was still in warranty, and they never heard of such a problem. I even saw the service manager of north star at walmart and asked him to level with me and he told me I was the first one to ever mention this. Every time I see other canyon/colorado owners I ask them if theirs does it too and they have the exact same thing. I hope the engine pieces stay together until I can trade it in for something different other than a GM. Next time I'll know better and do my homework so i don't have to feel like an idiot when service people lie to my face.
