I hardly think you have a lemon, just a lazy or incompetent mechanic. (I'm at 239000 on my '04 now). The mechanic should have read the trouble codes in the computer; if he didn't, he shouldn't have a job there( a middle of the road consumer grade diagnostic unit is only around $100 at the auto store, and will give you a detailed description of the error codes in 5 minutes, so don't let him b.s. you over running a basic diagnostic. Reference my post on cleaning the throttle body every 50,000 miles or so. Also, replace the fuel filter (10 minutes, $15). If those don't help, next guess would be a fuel pump issue.

In addition, I can't imagine how the alarm would "short" and kill the engine, unless it is an aftermarket alarm with an ignition kill switch built in. this is not very common these days, though. If you do have such an alarm, it needs to be checked by the alarm installer. There could be other electrical issues, including a loose or tarnished connection in the fuse block(remove and reseat all the fuses and relays one at a time(15 minutes), but I would need more info to get more specific. My point is, the mechanic should have tried these things. A good mechanic doesn't do what yours did- he finds the problem and fixes it. Probably why I do my own repairs!

I apologize that you are experiencing a concern with your vehicle. Has the dealership found anything new with the vehicle yet? How long has it been at the dealership? Thank you,

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:
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.

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.

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??
