Replying to: ficuss (Nov 24, 2007 9:45 am) I am replying to your message to my post about my 07 trailblazer....I have done some more research on this issue. As far as Chevy is concerned they say that OnStar is NOT able to deactivate a vehicle while it is in motion. (even if told to do so by police). Its is considered unsafe. So even if my car was stolen lets say with a full tank of gas, as long as that person keeps driving the car and they have gas- they cant shut it off...lets say the person stops somewhere and shuts the vehicle off- now OnStar can come in and deactivate the vehicle making it so the vehicle will not turn back on. But they can not deactivate a vehicle while it is in motion- which kind of makes sense, but.......i still dont understand what my truck is doing. It hasnt happened again- Ive had OnStar reactivated for about 2 weeks now. Dont know what will happen..no one really does. Thanks for the relpy though!!!!

Replying to: satvic (Nov 01, 2007 9:18 am) hey thanks for the reply....I've had the truck back up the the dealership for a steering wheel positioning sensor (nothing to do with the loss of power problem) but I was talking to the tech there and he says that my accelorator isnt run by a cable. Its basically all run by sensors. The problem is when they plug the truck in to the computer- nothings wrong, which is understandable because I dont have any warning lights to begin with when this happens. Anyways, I have reactivated OnStar...its been 2 weeks.. and nothing has happened since September. It only happened twice so maybe...just maybe it was a fluke in the system- which I find hard to understand on a brand new $30,000 truck. So I am basically waiting for it to happen again. The thing is I wanna get this all straightened out while I'm still under warranty. It all is really unbelieveable. I work for a heating and air conditioning company and I see less problems with new furnaces and air conditioners than I do with cars and they cost thousands of dollars less. Its amazing!!!! That is very strange with the Engine light in bad weather. Do you have Stabilitrak or any traction control system? I know that my Stabilitak light will come on in bad weather..but im not sure if its the same with your truck!!!   Thanks again

Replying to: satvic (Nov 25, 2007 9:26 pm) Stavic...I know we've all been going back and forth with messages...but I do remember when I had OnStar deactivated from my vehicle they literally pulled a plug somewhere near the rear passenger tire. Didnt see them do it, so I dont know exactly where it is, but that is where the OnStar plug is in my truck...Good Luck!!!!!

Replying to: vbell (Dec 12, 2007 10:57 am) vbell, my information came from a news report that stated that OnStar can now reduce engine power to newer OnStar equipped cars. They do not "deactivate" a car, they reduce power to a safe level so the driver cannot speed away. I would pose the question directly to OnStar, not Chevy or GM.   Try googeling "OnStar can reduce power" and read the reports.

Replying to: ficuss (Dec 12, 2007 4:43 pm) well, I think I figured out why the code scanner cannot get any reading out of the computer .. I changed the OEM stereo for a KENWOOD mp3 deck last year - DOH ! Well, SHEVY wiring runs through the stereo which makes the security system work etc...Also, you sistem chimes come out of your stereo when you open the doors etc.. SO, for those who consider another stereo, FYI you have to spend $100 or so for a special harness that contains a circuit box to preserve your security system capabilityes and has a speaker (for the chimes). I don't have the original harness anylonger to test my theory but I bet that after market harness with circuit is the reason my scanner can't read onboard computer.   As far as the loss of power, I don't have OnStar system .. and this car never did! I am a very concervative driver, I never floor the pedal or push it pas 2k RPM..   I am taking the vehicle into dealer on Monday to have them test the exhaust O2 sensor. I will have them check for the OnStart stuff........ will keep you posted.

Replying to: satvic (Sep 17, 2007 9:31 pm) 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. Replies to this message: jims1024 (Mar 07, 2008 10:09 pm) tahill (May 02, 2008 8:45 am) gredden (May 27, 2008 4:32 am)
#19 of 32 How do I get the codes in my 2002 Trailblazer???? by kymommaw Feb 18, 2008 (11:10 pm)
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?
#21 of 32 2007 Trailblazer loss of power by pwing Feb 21, 2008 (7:02 am)
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.

Replying to: satvic (Sep 17, 2007 9:31 pm) 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.
