I have owned my colorado for about a year and half now. I have had various problems. Such as it acts as if its running out of gas, and pressing the throttle just makes it worse. I have to shut it off and then restart it, then it runs fine. Wierd? I used to have the check engine light coming on quite regular, but haven't had it on for some time now. But I do have an engine rattle upon start up. As well as clattering coming from the valves or valve train. I have received a letter from GM stating that there is a problem with the cylinder heads on the L4 and L5 engines. The last time I went to the dealer they said that the problems that I am experiencing are not connected with the GM issue. I will be going back since my engine noises are worse. Hope I don't run into a problem with them since my check engine light hasn't been coming on.

Thanks for your reply to my post. The dealer has had my truck for a month and a half, although they've supplied me with a Sierra, a $42,000 vehicle to drive, it's still not my truck. I'm waiting to see when and if the engineer will make an evaluation on what manner or method they will use to eliminate this issue. I no longer want the vehicle and would like nothing more than for GMC to replace with a new vehicle. They have told me to pick up and drive my truck, that there is no reason that I can't drive the truck. I informed him that the truck is not fixed and I don't want to drive the truck until it is. I wish you luck on yours and will keep my problem posted as to the results.

I have an 08 Colorado that does the same thing. When I took it to my dealer, their
spew was that there was no documented issue of this sort in their data base, so
they said that it was probably normal. Some days later when I received a call from their customer service dept. wanting to know why I had refused their recomendation to change the oil to see if it would remedy my issue, I told her why in the world would you need to change the oil in a brand new truck with 2300 miles on it, number one and number two, if that was the diagnostic direction that they were going to use I don't think I would want them working on it period. She went on to reinforce the the fact that there was nothing in their data base to indicate that there were other people with this problem, so I ask if my complaint had been entered into the data base. She said "probably" not because they had not found a resolution to the issue. I said that makes no sense and therefore their data base is useless. She then asked what I thought should have been done. I said some sort of oil pressure test, especially at start up should have been done. She left me on hold for sometime and went to talk to her service manager. They then set up for me to bring the truck in and that they could do such testing. To make a long story short, they had the truck for 3 days and said that they could find nothing out of the ordinary. They at first said that they could not get it to make the noise and when I pretty much called them liars and took 40 bucks out of my wallet and said lets go over to the truck right now and start it up and I would bet that it would sound like a diesel engine when it started, the service tech said that he could hear the noise, but
the pressure test didn't indicate any problem. The service advisor then chimed in that he had been watching the test gauge and it seemed to him it was slow in coming up to pressure, but nobody added anything more to the conversation and
since they all said there was nothing from GM indicating this to be a "known issue"
they offered no resolution. They did however leave me with the assurance that I had "plenty of warranty left" if it were to become major problem.

I appreciate your input. They have had my truck for almost 2 months now. I informed the GM service rep. that I did not want the truck back. I wanted a new truck. She told me she didn't think they would do that, but told me that she was told that the truck was 98% right and nothing else could be done. I told her that if it's 98% right, it's still wrong. I told her that I am an aircraft mechanic and how would the pilot feel if I told him the engine is knocking, but it's 98% right. You think he would fly that airplane? I paid good money for this truck and I want it right, and I want to be treated like I have a valid complaint, and not trying to get something for nothing. GM has a bad issue about making people feel like complainers and like they're trying to get something for nothing. Just treat me fair is all I ask. I was called today and she told me that a decision has not been made at this time and that it would require 2 more days. I told her she's had the truck for 2 months, what's 2 more days? I also was told that no one else in the industry had a problem with that noise. I have since learned there are a number of people with the same issue. Thanks again for your input, but I don't a warranty to fix something that is broken now. I want it right to begin with. Warranty is good, I hope, but I do not want to use it on a new vehicle. I want it right, especially since there's less than a thousand miles on the truck.

At this point you may want to check out the lemon laws in your state. Good luck.

I just purchased a 2008 Chevy Colorado 2.9L crew cab. At 1400 mi I began noticing a knocking/rattling noise during cold start-ups. The noise diminishes after a few seconds, but has now worsened at 4100 mi. I have recently brought the truck into the dealer for servicing. Their initial diagnosis was that the spark plugs were making the noise!!! Spark plugs!!! I then had them keep the truck another day, they came back with a thought that it was now the air pump...possibly, but were not sure about "what noise" I was referring to. I now have my truck back, the noise remains, and was told that I shouldn't worry because of the 100,000 mi warranty! I spoke to the VP of the dealership today and a meeting is scheduled with the mechanic, VP, and myself later this week.

I agree with everything you've said. I don't buy the warranty thing either. If it's
not right they need to fix it or replace it. I know have a recall letter on it and the
windshield wipers now come on for no reason. I am about to take it back for
these so I will bang the drum on the noise again. There no doubt that they can hear
it now because it has gotten more noticeable. I received a response to a post I
made on another site from a GM mechanic who says that he has dealt with this
issue. He claims that they "threw parts" at this engine for a week and never found
the resolve. He claims a GM engineer told them that this noise was normal. It's
apparent that GM is aware of this issue with some of these engines. It's just gonna be a bear to get them to do anything.

I really appreciate your response. I just received from GM a notice that they want to talk to me about a settlement or what they are going to do about the vehicle. I missed her phone call this afternoon; she will call me on Monday. I feel sure that GM is not going to do anything but tell me the 100,000 mile warranty will cover it all. I informed her last week that I did not want the vehicle. The dealer has had it for 2 months and I feel with the other inputs I've received, I will have nothing but trouble with this vehicle. I don't have time to drive back and forth to the dealer so they can diagnose something they said they can't fix. I'll keep you informed what the resolution is. I really appreciate your input.

I appreciate both you and ddidio replying to my message and concern about my 2008 Canyon. I just got off the phone with the GM rep, Ms. Diane Tolver, at 1866.790.5600 ex. 12307, and she informed me that the GM engineers are convinced that there is no problem with this engine and it's perfectly sound, and told me when the argument got somewhat heated, that it was a lubrication issue. I asked her to repeat that and she said it was an issue, not a problem. I told her that an issue is a problem. She said the case would be closed because there was nothing more they could do. So I will pick my truck up and start the process of the lemon law. I told her that if they could resolve this issue we would not be having this conversation. There is an unresolved issue, which I want addressed, and every Canyon owner should make an effort to demand something be done about this so-called issue. I would like to hear from more '08 Canyon owners to see if they also have some of the same "issues" that we have. A warranty is to fix something that goes wrong after the purchase, and should not be used to appease someone because of a problem found in a brand new vehicle, especially and "issue" that is not common to all like vehicles/engines.
Thanks. Semper Fi
