Well...it's back. The dealership put a ignition switch on it and said that the switch was kicking the anti-theft mode in. That is why it will start sometimes and he also warned that you could be going down the road and it would also stop. I'm not sure that this will work, but it did start. But my question was how do I prevent the anti theft device from doing this again. Sounds to me like there should be a recall on all the ignition switches if this is what is causing the system to mess up. I would think that either Chevrolet needs to recall for ignition switches or figure out how we can stop the anti theft system from coming on.
Apparently, you are the only person I have heard complain of this so there will not be any recalls. Sorry! Welcome to the real world, you should try to visit here more often! geessshhh.
I am in the real world. You need to read what I wrote again. I said there should be a recall because I have heard of others doing this. In fact mine is now back in the shop and they are working with Chevrolet to buy the vehicle back. Next time you should add the comment as to why you were visiting this site to begin with. I came here to read if anyone else had problems and there seems to be at least one other than me. That is why I commented on this survey. So you pay 30,000 for a new vehicle and then come back and tell me welcome to the real world when you miss work because you can't get there.
A few of you need to learn how to write. I do not know who "they" are, from the first posting.
I have been reviewing the comments on the Trailblazers and have a 2002 LS that has similar problems with not starting. Everything else (horn, heater, lights, etc.) works, but the car won't start. This has happened 3 times so far. Initially it happened around two and a half years ago, but started for the dealer the next day. Then again approximately a month ago when it was towed to the dealership and a battery installed. The next week it failed to start again and was towed back to the dealership. They were initially unable to start it upon arrival, but when the mechanic went outside to check it the next day, it started right away. The dealer is also perplexed by this and said that diagnostics showed no trouble codes. He said that since the problem started when in the warranty period, he would try to make repairs under warranty... WHEN it happened again since there was no other way to diagnose it. This vehicle is driven by my wife and we are very leery to have her take it to visit her parents (about 300 miles away). I will keep my eyes on posts for any similar problems and will update this site if I have any more information.
Same problem tonight on my wifes trailblazer. We have had it for two weeks. It was in the shop twice to have the fan replaced for a ticking noise and now it won't start. All lights, heater, etc. work. It is going in tomorrow. We'll see what happens.
I had the same problem with my 2000 Chev Silverado 2500 pick-up.After two years and several parts changes the dealer finally determined that the Anti-theft system was to blame. I believe it was misreading my key computer chip and not allowing me to start my vehicle. Something was replaced and there were no further incidents.
Boy, if wind noise is your biggest problem hold onto that thing for life!! Sounds like a pretty lame reason to NEVER BUY ONE! Give me a break and turn up the stereo!!
My father-in-law owns a 2003 Trailblazer and the car was wonderful up until this morning when we got up and tried to start it and nothing happened. Everything comes on, but it will not start and from reading everyone else's comments this seems to be a regular occurence. The radio and everything comes on, but it just won't start.
I own a 2003 Trailblazer and have the same not starting problem. Thank you for talking about the Anti theft because that is something I will have them check. I replaced the battery, but I am still having the problem. Another issue I've had to deal with repeatedly is the wiring in the taillights and the head lights. The wiring harness going to the headlight apparently got too hot and it melted therefore my headlight wouldn't work. Dealership was going to charge me $240 to replace harness. I bought the part for $13 and it took 2 hours, but replaced it myself. I think the electrical systems in these vehicles is terrible as is evidenced by all the recalls. I can't believe a wiring harness that isn't located even close to the headlight and is in a sealed area would melt! I would never by a trailblazer again nor would I recommend one to anybody.
Has anyone had any luck having this problem fixed or have you just had to live with it?
For anyone that is having problems with a trailblazer not starting, the problem is your ignition switch is faulty and needs to be replaced. It is not an alternator, or anything else. Don't let the dealers give you the run around. There is a TSB for this though I'm not sure of the number.
We are having this very same problem with our 03 Trailblazer. It will not start, but the lights, radio, etc. all work. It has been to the dealership 3 times now, last time they said the battery was dead and installed a new one, but it wouldn't start again the next day. It has now been sitting at the dealership for 3 days, but it is starting fine for them. We are going to tell them just to go ahead and install a new ignition switch, even though they are reluctant to say that this is the problem. Just wondering if this solved the problem for anyone else, or if there is something else we should consider... any response is greatly appreciated.
We're having the same problems on our 03 Trailblazer. I took it to an independent mechanic and he basically thinks it's the ignition switch, but couldn't do anything since it started for him. I had to have it towed and it cost me over $100. It's not the first time the car has done it to us. We currently have 57k miles on it.
Hi, I own a 2003 LTZ Trailblazer with 60,000 Km. I live in Greece and I have the same problem. It won't start first thing in the morning (when I am doing the school run!!!) if the temperature is below 10° C. I was told to check maybe the gear was not in park so I try putting it in Neutral and then park again, I remove the key and put it back in. And usually after 7 to 10 tries it starts. I don't know what eventually makes it start. For the rest of the day its fine, it starts as soon as I turn the key as expected as many times as needed. It's just the first time in the morning. Some mornings when it's not so cold I have no problem, or on weekends when I use the car later in the day. The only thing that I haven't tried is using the spare set of keys (driver 2) if it is the anti-theft thingy that causes the problem as mentioned above. I haven't taken it to the dealer because I know that it won't do it when I go. I probably have to leave it there overnight parked outside and they have to try and start it at 8:00 o'clock in the morning. But its good to know that other people have the same the problem. I can tell them that.
