    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??

  • 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

    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

    Hello Crashrecovery,
    I apologize that you are having a concern with your vehicle. How long has the concern been present? Can you please email me your VIN? Do any codes ever come up on the DIC? You can get my email by clicking on gmcustsvc. Thank you,

  • 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.
  • bmintonbminton Posts: 16
    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!
  • jpfjpf Posts: 496
    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.

    I bought my ,04 Colorado from dealer inventory June of '05,since then it's had two recalls that have been taken care of (Engine, Fuel Cap) have yet to receive any notice on or about the light problem. never the less last month the fan stopped working PERIOD my service tech troubleshot the complete system too find no problems so we decided to replace fan motor STILL ONLY WORKS intimately. back in '06 the dealer replaced the fan switch so I thought only to find that connection was taped (don’t know why) the dealer had it for 2 days and told me they replaced the switch. brought it back several times for two very annoying rattles inside the cab, the service writer went with me twice and twice they held it over night only to be told they couldn’t "duplicate " the problem. same with the rattle coming from under the hood. not too mention I’m forever changing light bulbs. BUT TODAY 9/7/10 was the straw that broke the camels back on my way home from the shop today (fan still) the engine just started skipping was lucky to get it home. In dyer need of answers this is getting costly seeing the vehicle has and still is well maintained!!.

    Bought a 2005 Chevy Colorado from Ed Morse in WPB FL, when they closed, they threw out all their records. I found out afterwards also they sold me a truck that had been a rental, so every jerk that got thrown out of his apartment, rented my truck for the day before I got it. At 29K engine misfired on #4. Throttle body cleaning, injector cleaning didn't work. waited 2 months wiht it in the shop to replace the cylinder head, still does it. Poor gas mileage, had two dealerships and three local guys repair it, clsoe to a thousand bucks lighter each time. Each time they reset the computer and within a few weeks light comes on again. Engine runs rough, poor mileage. This morning, rpms all over between 600 and 300 trying in gear, thought I was going to die. This truck has been a problem since I got it and it stays fixed for a couple weeks and the light comes back on.
  • Ri1958 mentions a fuel cap recall. Does anyone know the details of this recall, or maybe a recall for the truck? My 05 Colorado Z71 might be the worst vehicle I've ever owned (running a close 2nd to an 88 Bonneville). It's clearly a lemon with many electrical problems.

    Recently, my Fuel Cap warning light displayed, went off after a restart and then came on again a week later. After shut down and restarting 2 hours later, the engine light came on. The engine light went off for awhile but has since come on again. The Fuel Cap light goes on and off irregularly. Is this an electrical problem or actual problem (I did read code P0455: EVAP System Leak)? A GM mechanic advised that it's $600 for the test to determine what parts need replacing! Apparently, there are a number of parts that, if defective, will trigger code P0455.

    The no-start Gremlin also showed up again on 10/15/10 after an extended absence. I’ve had inadvertent no-start symptoms for over 2+ years but the problem has never been determined or discovered by the dealer (they had the truck for over a week once). Of course, GM will not cover this issue because I can not provide proof the problem was first addressed within factory warranty.

    There are numerous posts on Edmunds forum about the no-start Gremlin, Jhacket (reply 505) and crashrecovery (507) most recently. Why won’t GM acknowledge this problem? Can anyone provide more information about codes B2960 or B1383 mentioned by crashrecovery? Are these codes the actual problem and how much will it cost to fix? Does anyone know if GM will cover this problem as a known defect?

    My ABS Fault warning light has also displayed on and off since 8/2008 approximately 1 month after the dealer did a brake job. They claimed it had nothing to do with their work but they were happy to advise that the right front hub wheel bearing assembly and sensor needed replacement ($800+). I replaced the parts for less, albeit not at the dealer, yet the warning light still came on and the ABS braking still didn’t work. I tried replacing the sensor again and now the ABS braking kicks in inadvertently on dry pavement, then the light comes on and the ABS stops functioning. What gives?

    Clearly, these trucks have major defects, many of them electrical. This truck is bleeding me, as I’ve easily invested close to $2G in repairs beyond the factory warranty, and that doesn’t cover the GM costs within warranty.

    Since 05, I’ve had problems with:
    4W self engagement
    Tie rods (replacement within 20K)
    Transfer case control module & leakage
    Front axle seal leakage
    Emergency flasher module self activation
    Various squeaks
    Trailer hitch harness inoperable
    Defective front seat cover
    Throttle body, actuator
    Injector feed wire breakage
    Brake lamp switch
    Radio display
    Radio Bezel
    Cylinder head and intake valve replacement
    Cracked manifold
    ABS braking system default
    EVAP system default

    Is this normal or does anyone know if I might qualify for the Fed lemon law. I was a previous S-10 owner and only experienced typical maintenance, wear and tear problems.

    Seeking inexpensive help or suggestions. Any answers are appreciated. Thanks.

    I hate to say it, but your issues are a faded nightmare, as I too had the same issues you speak of with my 05 Colorado. My best advice would be to get rid of it as quick as possible. I find myself up side down in my current vehicle, but so much easier to deal with a bigger payment, than those repair bills on top of current payment. Colorado's are just junk, although there are some people whom have them and don't have the problems, but seems a rare find. Again, with the problems your dealing with at this point, it will only continue, and from what I've read, there is no help from GM on its way..cut your loses and move on..good luck to you

    Just wondering if anybody can help me before i bring my truck to a dealer I have an 04 colorado and the truck does not go over 30mph, the indicator reads reduced power. Can anyone relate to the same problem?
  • You are as miserable as I have been the last 3 years. I have a 2006 GMC Canyon. It has a 2.8 liter 4 cylinder. It never runs good. It idles rough. The check engine light is off and on all the time. The last time I brought the truck in it was some actuator and they cleaned my throttle body and adjusted the fuel with a computer. Costed me over 310.00. It fixed the problem for a while. Now it's doing it again. I brought it back to them and they said I needed to replace my whole fuel system. From my fuel pump, injectors, lines cleared and new fuel rails. I don't know who to believe anymore. This truck has cost me a mint. I had a 1998 Isuzu Hombre and put 538,000 miles on it and never had problems with it. What kind of junk had GM built here? :sick:
  • I have an 06 GMC Canyon and I am having the same problem with my blower motor. The blower only blows on the high speed. My driver side light olso fogs up. I am also having a bad idle problem. It misses horribly at idle. Does anybody know why. I would love to know why it does this.
  • It takes those few seconds for the oil to get pumped into the engine parts. That means for 2 seconds your mechanical part are going oiless.
