We had the truck towed to the dealer last night. I am not sure if they have had a chance to look at the truck yet. I was going to call them in a few minutes to ask them to look at:
 
1. Head/valves
2. Exhaust Manifold
3. Ignition System
4. Fuel Pump
 
I do not think they looked at any of this stuff when they had our truck earlier this week. We initially had our tow service take the truck to the dealer on Saturday, 7/17 right before they closed. They didn't get around to looking at our truck until Tuesday, 7/20 and put the truck on the diagnostic machine and couldn't find anything.
 
The truck even started for them so they took it out for a test drive and the truck stalled out on them. They had the truck towed back to the dealer and then advised that the stalling might be caused by a short in our alarm system. We gave them permission to disconnect our alarm. They called us on Wednesday, 7/21 and said that they ran the truck for 11 miles and it worked for them. We picked up our truck that evening.
 
Unfortunately, the truck stalled again on my husband on Thursday, 7/22 on his way to work. We had the truck towed back to the dealer last night. So far they have not done much to figure out what the problem is. Through my own research I was able to figure out many people are having the same issues. We really need our car. I am 5 1/2 months pregnant with a 4 year old and a high risk pregnancy.
 
The dealers contact info is: Lehmers GMC (925) 685-4481
 
Our warranty expired earlier this year.
 
Any help would be greatly appreciated.
 
Thank you,

The dealer finally called me back at 12:00 p.m. They said they will try to figure out the problems. I told them about the research I found re: others with this problem and it ended up being the heads and a cracked exhaust manifold. Don Slaney at Lehmers said that it couldn't be that. I find that hard to believe since so many other people have had these issues. I also asked him to check the fuel pump and ignition system. He spent a lot of time talking over me and telling me they will look into it.
 
It seemed like he wouldn't even consider the fact that it could be the heads and a cracked exhaust manifold.
 
I am really unsatisfied with the service I am getting but feel like I have no choice but to have my car there.

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.

Anita....you 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.

#496 of 709 04 colorado with missfire by cancol04

Aug 04, 2010 (10:05 am)

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,

#497 of 709 05 colorado reduced power mode curse by ohcolorado

Aug 10, 2010 (1:29 pm)

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!

Aug 21, 2010 (5:08 pm)

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
