We bought a 2002 Trailblazer from AutoRama about 4 months ago, if even that. But about 2 weeks ago I was driving and got lost on the highway and ended up 6 hours later home. But what would normally take me about 20 minutes up the highway from where I finally figured out where I was, it took me about 1 1/2 hrs. to get home. All of a sudden the power just went. I mean, I had power but only the first gear. Couldn't get out of it unless I backed off and barely touched the gas peddle. At first I was trippin cause when it first happened I kept tryin to make it go, but all I got was roaring so loud and the vehicle wouldn't go any faster at all. I could only get on the side gravel part of the highway and go no more than 20-25 miles per hour. Eventually I had to get over some lanes and I finally would get it up to atleast 40-45 but no more than 45. Thank God there was alot of traffic that was making everyone go pretty slow but alot of times I thought I was going to get in an accident since it was so hard to get it up to 45!
 
So could it be the transmission? I had been getting on star to pop up in my little window above the steering wheel and I would push the buttons up above and I would hear a message from on star telling me that on star wasn't activated and to activate it I needed to call such and such number. I never have since it's an extra exspense that we can't afford right now.
 
I'm really frustrated as to what could be the problem.
 
Could it be from bad gas? The reason I ask is because I had stopped at a BP station in the outskirts of some town I was in.......yeah when I was lost......and before stopping there everything was fine with the trailblazer!!!
 
I do remember that when I was lost, I had my 21 yr. old son in the vehicle with me. I was trying to get him to an insurance place so he could get insurance on his vehicle and ofcourse I got lost on the way there too, but he was yelling at me and needless to say I was pretty aggravated and I would go really fast a couple of times cause I was so frustrated at him yelling at me and not knowing where the heck I was. But this was way early on, I didn't have any problems at all til after I got the gas at the BP station.
 
I guess I'm just wantin somebody to tell me that it isn't something serious and if it's just from bad gas then maybe it's a simple problem that I can fix myself.......probably not huh!
 
But if anyone of you can help me out with this I would appreciate it. I've been reading on here and I'm so upset at all the problems that everyone is having. I've been so happy to have a vehicle, I thought was going to be safe and reliable for me to travel out of state to see my family, which I have a few times since we purchased it, but now I'm just heartbroken. I couldn't even spend any holidays with any of them this year.
 
So I'll be prayin that somebody can help out on here! Thanks for listening!
 
P.S. I'm not from this state so that's why I got so lost.

#19 of 74 How do I get the codes in my 2002 Trailblazer???? by kymommaw

I really need some advice here. How can I get the codes from my 2002 Trailblazer myself?
  
Is there a certain number of times to turn the on and off key switch on and then will it tell me if there is anything wrong with it by displaying codes?

I purchased my 2007 Trailblazer in March, 2007. Since then I have had 3 episodes of loss of power. Each one I was driving and I loss power, engine still running but no power to it. My check engine light went on and then off. I was lucky because I did not get in an accident. The only thing I could do was turn off the engine and restart and it was fine. It happened in August, December and now February. I took it each time to the dealer where I purchased it. In August, they said they couldn't find anything. In December, they found an error code and replaced a sensor and said they fixed it. Now in February, they found some error codes, replaced a module but told me they have no idea if the problem is fixed or not. Basically, I was told to drive until it happens again. I explained my concern of my safety - what would happen if I was going 65 mpg and this happened on a busy freeway. They said they can only deal with what the computer tells them. So at this point, I got it back from the dealer last night and found this website and hmmm it seems like I'm not the only one having this problem but still no one knows what is causing it.

My 05 went to the dealer today for this same problem plus a few others. OnStar sent my monthly email with an diagonstic alert on the emissions systems. Service center replaced the O2 sensor. We'll see if this works. Gota take it and have the battery replaced also, I'm not paying their price. My dad has a 02 pickup that was doing the same thing. His would quit doing it when he added fuel treatment or injector cleaner but, two days ago it died. His turned out to be the fuel pump.
For those of you considering going foreign, been there done that, good luck. I had a Kia Sorento. We loved the Kia but, it stayed at the dealer almost as much as we drove it. Always for the same problem. Always had to call Korea for permission on the minimum they could do to fix it. The last time it went in they stapled a wire on the transmission, we took it straight to the Chevrolet dealer and traded. At least with my Chevy I get service, don't have to wait on Detroit to make a decision and something always gets replaced not stapled, which at least makes me feel better.

What do you mean "they stapled a wire on the transmission"?

I don't know what that means. That is all they told me and was on the repair statement they gave me. I didn't take the time to look under it to see what they did, I'd had enough of the run around.

FIRST LET ME START OFF BY SAYING THIS ABOUT ONSTAR - THE TECHNOLOGY IS THERE TO "SLOW U DOWN" IN 5MPH INCREMENTS, WHEN REQUESTED BY POLICE. THEY CAN NOT JUST CUT POWER.....NOT SAFE. AS FOR EVERYONES CONCERN ABOUT LOSS OF POWER - GO TO DEALER...I AM 100% SURE THERE IS AN PCM UPDATE FOR THIS. I AM A SERVICE ADVISOR/ASSTISTANT MANAGER FOR CHEVY DEALER IN NJ. ALSO OWN THIS TRUCK.
GOOD LUCK TO ALL

Chevy 2005 TB
My truck first starting having hesitation issues when going up hill 35,000 miles. Of course I took in to the dealer they kept it for 3 days and could not find anything wrong or duplicate the issue. They told me it was probably a bad tank of gas. Things were fine...nothing happened until last week. Due to "other" issues I waited to have my 30,000 mile check up done last week. I am currently at 45,000 miles. I went to get in the truck to take it in and the check engine light came on. Not a big deal as I was already on my way to the shop, they did a diagnostic test and it was coming up as a o2 senor issue. The mechanic working on my truck told me what the code was but said that he did not think this was the issue. He did the 30,000 mile check up; the check engine light went off. I picked up the truck and things were fine until the past Tuesday night. I was driving to work...sitting idle at the exit ramp my truck shakes a bit then dies. I cut the engine off, restarted it no more issues on the way to work. That afternoon...same thing happened. Waiting my turn at a stop sign, car dies. Turn it all the way off, restarts with no issues. I drove it home. Wednesday night while turning onto our subdivision street coasting at a low speed the truck looses power again. Called up my mechanic he told me to bring it in right away...just got a call from him stating that GM has a PCM update that will re-calibrate several things from the transmission to the electronic throttle control. I will repost in a few days to let you know if this does correct the hesitation and stalling issues that I have been experiencing.

Please let us know!!
**************************************************************
I have a 05 TB with 60k miles. The problem that I am having is that when the engine is cold I will have power loss and as soon as I take my foot off the gas, the car will die. The engine starts right back up. The check engine light nor does any other service light come on. This problem is very sporadic. I did add some Lucas fuel treatment and we did not experience the problem, but I think it was just luck. This problem happened to my wife this morning. Any ideas???
