    Default Check Engine Light

    Hi,

    Has anyone been having a problem with their check engine light?
    I took my 05 Colorado to the dealer and was advised that it needs a new head. I have 81000 miles (98% Freeway miles). My extended warranty expired at 75000. I have a church member who also has the same model but only 35000 miles with the same problem, needs a new head. She is under warranty but I was told that I would have to pay about $4500.00 for parts and labor.
    I have called GM and informed them of the situation.
    If you have expereinced the same problem, can you please advise me what to do for GM to give me a price break if not cover the whole thing.

    Thank you for your help.

    What has your overall maintenance experience been? Any other troubles with the car during the 81k miles? Do you save your maintenance records? If you are going to buck GM's normal warranty procedure you are going to need some ammo.

    Hi, chances are you do need a new head. I worked for Hummer for a short bit and the H3 has the same engine. In the year and a half I worked with the company I replaced at least 20 heads. All around 30k GM never gave me at least a clear reason this was happening but it had somthing to do with the casting and seating. It always leaked out of the same side twords the rear of the head. You got alot more miles out of that head than most people I know, my best friend has an 06' Colorado and he replaced his head at 9k. Unfortunately if it is out of warrant the bill is insane, I hope the dealer helped out a little because this is a common problem.

    I have an 04 and the only time my check engine light has come on was when I had a cracked cylinder head and clogged throttle body. That made it idle rather rough though, so you would probably notice if it was that.

    I read on one of the other forums that the this issus was covereed until 100,000 miles under warranty. Here is a address to that forum.
