    A cracked head/exhaust manifold shouldn't keep it from starting or stalling. It has to be fuel, electrical, or computer related I would think.
  • tbone_raretbone_rare Posts: 96 don't mention how many miles your Canyon has on it. I would think after 5 years of good service, even a few problems with your truck would hardly cause you to classify it as a "lemon". It sounds like the stalling is all related to the same issue....whatever that is. It's just a matter of bad timing that your extended warranty just expired. There are very few vehicles on the road today that will give you completely uninterrupted service after 5 years. I think after your technician has a chance to do a thorough inspection of your truck and is able to diagnose the problem, your vehicle will be good as new! BTW....most importantly, good luck with your pregnancy. I hope you have a fantastic life as a new mother!!!

    I'm somewhat agreeing with the dealer that it isn't related to cracked heads. Such a defect would probably not be intermittent and would also exhibit rather severe symptoms.

    i have a 05 colorado with 95,000 miles on it, i have replaced the mas air, an map sensors. the truck will run fine at low speeds as soon as you give it gas it will flood out an start to blow black smoke an the engine will die. I have installed a air/fuel gauge an it shows to be at 10.0 at normal driving speeds all the time no matter how much gas you give it. this started about a week ago an gets worse every day. dose any one have any more ideas what else it could be??

    jeremy, :sick:
  • Hey,
    I have an '04 colorado with the inline 4 and approx. 60 thousand miles. Last week I experienced a bad missfire which has not gone away. I thought it may be a bad plug. When I pulled out the number 3 and 4 plugs they were fouled with oil.
    I change the oil every 3000m, so I can't imagine it the rings. Before I bring it in, I was just wondering if this is a gasket promlem and if so what should I expect cost wise? Also, is there any 'bulletins' with respect to this problem that I'm not aware
    of? Just trying to be informed when I go in to the dealer.

    Thanks so much,
  • Well, after several problems over the life of my 2005 Colorado, I thought GM might help me...What I got was a short and rude response to a request for some goodwill warranty help! Obvious defective wire connectors, GM is well aware, there is hundreds of posts all over the internet about Blower Motor wire connectors melting!
    Now after several attemps to diagnois my reduced power mode, I find it is another faulty wire connector to the throttle position sensor! GM spends millions on advertising, but will lose a 30 year customer over a few hundered dollars...GO FIGURE THAT! How many people have had problems with intermittent electical problems because of faulty GM connectors?
    A definite design flaw! I have been buying GMs for 30 years, and a retired GM dealer employee! NO HELP FROM GM though! I have simply asked GM customer service to provide me with a pigtail connector, which they should under recall anyway.
    Problems with my Colorado:
    Headlights fog up
    Front tires wear prematurely
    Roof leaks
    Brakelight switch
    idol problem (New GM Head)
    Throttle Body replaced
    Heater Blower Wires/connector burn/melt
    Throttle position sensor- DEFECTIVE WIRE CONNECTOR
    All of these things traced to manufacturing/design flaws!

    I've noticed that a few people are having the same problems I am. Does anyone have a fix on these problems? My truck has 32,330 miles on it and last month it didn't start so I had a tow truck on the way to pick it up and then about 2 hrs after it didn't start I tried again before they towed it to show someone. Then it started so I took it to the dealership and they told me there was nothing wrong with it. I also had them look into another problem I have with it. When I'm driving and I come to a stop the truck will drop to about 500 RPM for a second and then jump back up to idle which is about 6-800 RPM. When it does that it feels like the truck is going to stall out but hasn't yet. Again the dealership said they can't find anything after hooking it up to the computer. They told me they hooked it up to there starting system computer. Then today it didn't start again when I was downtown so I took a video of it and I'm going to show the dealership. It didn't start and I tried 3 separate times. After calling Chevy's tow service it started about 30 mins after the first try when it didn't start. when I talked to service department at chevy last month when it didn't start they kept telling me " well maybe you left a switch on and didn't know about it and that's why it didn't start". Then they tried to tell me that the battery might of died. Even though it wouldn't start but it was turning over. My truck is still under the 3yr 36K warranty so it's not costing me anything but I don't want to have to worry about if it's going to start. Any info on this would be helpful so I can take it to the dealership and help them do there job. Thank's

    That Shreveport Obama Motors plant has shut down.
  • bmintonbminton Posts: 16
    Can you spell, "UNION. GM is owned by Obama. Obama got elected by the Unions. Unions breed LAZINESS. Get it. They will never help you, They are spin doctors.
  • dmathews3dmathews3 Posts: 1,739
    The problem is not UNION, its the truck is a Japan designed product and like all junk designed in Japan it sucks. When the Colorado was the S-10 it was the best truck for its size on the market and it was designed and built by Americans, not a piece of junk americans got stuck building. You as a Bushite of course wouldn't understand that since you and yours almost brought down America with your wallstreet crap. :P

  • Howdy there. Do you have any updates on your engine start up knock. I've a 2008 2.9 with about 21k miles on it now, its rattling loud now after it sits for an hour or so. It goes away after a few seconds. Currently it's at the dealer; they refuse to fix anything.

  • Sounds like we're having similar problems. I have an 06' Z71 Colorado, and last fall it began giving me problems which I'll describe in a moment. I took it in to the dealership a month or so later where it spent 3 days only to be told nothing could be found. To this day I've just been putting up with it as I haven't had time to take it and leave it again due to being in school full time with literally no breaks.

    Here's the problem. The truck won't start but will turn over. Initially I would try and try for a few minutes then pop the hood to check the battery cables just in case they might be loose (about as much mechanicing as I'm capable of), and then about 10 minutes after first attempt - BAM started right up. I've gone a few weeks with this not happening, and have also had it happen every day, maybe twice a day for a week. It never fails, about 10-12 minutes after first attempt it starts right up.

    Aside from taking it back to dealership which I'm trying to arrange a time and another means of transportation, any suggestions.

    Yes, there needs to be a recall on this junk. I have had nothing but problems with this vehicle. :lemon:

    Well I was contacted by a representative on here and they helped me light the fire under the dealership. When you do get a chance to take it to them tell them to look for a TSB (Technical Service Bulletin) that GM puts out to help mechanics fix issues that they haven't recalled but they know there is a problem with them. Like I said before when I took it myself they said there was nothing wrong with it. Then after I had a 3 way call with them and a representative they seemed more willing to help and try and fix it. They had my truck for 2 days and the last 2 hrs before I went to pick it up I called to check on it and they said there was nothing wrong again. So I did some research on "Chevy Colorado TSB" and found a few that I told the dealership about and asked if they tried those methods to fix my truck. It caught the guy off guard that I knew about those and that GM puts those out to the dealerships to help there mechanics. So he tried to beat around the bush by saying he's sure his mechanic would of looked at that stuff I told him about. Then I went to pick up my truck and all of a sudden they had found what was wrong with my truck. They got the codes of B2960 and B1383 from the Charging System which is the ignition. The B2960 is the - Sec Sys Sensor Data Incorrect but Valid (History) (Immature). The other code was the Oil Level Lamp Circuit Short To Battery. They had to order the parts and I'm still waiting for them to install it but when they do I'll let you know if I still have any problems. I haven't heard of anything that is a temp fix to stop the problem.

    GM Customer service is a bad as it gets! They will twist you around like a toy top!
    Not one rep I talked to spoke very clear english anyway, so it was hard to understand. But I will tell you this, I have complained every place I could about GM!
    They spend millions of dollars on advertising, then piss a customer off over a hundred bucks. Make no sense, but they don't care!
    Not one GM rep has the guts to make it right with me on the lemon Colorado, with obvious manufacturer defects!

    I have owned 2 S10's; a 4 cylinder and the V6. Very good trucks. Rides better than the Ford Ranger (test drove a 2009 model a few years ago). I can see why GM had to file for bankruptcy. Bad management decisions. They gave Isuzu hundreds of millions of dollars for the S10 replacement and wound up with a less reliable truck. They could have easily spent much less money by updating the S10 and would have had a better more reliable truck than the Colorado. My two cents worth.
  • Thank you. I'll be dropping my truck off tomorrow evening at the dealership. I have my fingers crossed for a good outcome. I have contacted GM and have been in touch with a service rep although I'm not certain what good that has or will do. They seemed to be surprised when I told them of the problem so I'm just hoping for the best.
