Starter problems of the 2003 Chevrolet Trailblazer

My 2003 chevy Trailblazer does not start. There is no specific time, place, or event that leads to the vehicle not starting every couple of weeks the vehicle just doesn’t start. I will let the truck sit for an hour or so then attempt to start it, then it does start. I have taken it to the dealer and they couldn’t duplicate the issue I was having. I did some research online and others have suggested it could be the battery, temperature sensor, ignition switch, or starter. I have replaced all but the starter but the problem persists. I have been told that the starter is good so I am at a loss as to why the problem keeps occurring.

I am the original owner of a 2003 chevy Trailblazer. When I first purchased the vehicle in the month of October/2002, I didn't experience any problems until maybe the fourth year, going on its 5th; right before the warranty was about to expire. The first problem I encountered with the vehicle was the transmission. It didn't want to change gears properly. Because of the 5 year warranty, the dealership was able to fix that problem, at that time. Today, I continue to experience transmission problems: with a loud noise, a struggle in horse power and a vibration when I am at a complete stop. I have spent so much money on other electrical parts as well. I have purchased over ten light bulbs for rear brake lights that continue to malfunction. I recently replaced a relay because the head lights would constantly go out after the vehicle was turned on. I replaced the fan clutch and water pump because they both went out. I also replaced a battery and two starters. For the past few months, my vehicle smells like fuel everytime I turn it on. I am asking that your department look into all of these claims. It appears that almost everyone that owes a 2003 Trailblazer has been experiencing the same issues, but yet; no one is doing enough to protect all those consumers who have been grateful to this country in purchasing american made vehicles. A sincere thanks.

My 2003 Trailblazer ext. Would not start today, all dash lights come on but gas and voltage gauge dont register. Keys and key fobs are not recognized also only says unkown driver . It will not crank at all or even make noise, battery,alternator,starter and all fuses have been checked and are good. There is no security light that stays on and my key will remove from the ignition! front door windows and door locks will not work or radio. . . . . All lights, a/c, back windows, sunroof, power seats work!. . . . . . . Have not been able to find problem.

In 2010 I had to have the ignition starter switch because my 2003 Trailblazer would not start. This cost 300. 00 plus the tow charge. On may 7th. 2015 I had to have the same switch replaced again, now not two weeks later the ignition switch is acting up again. I called general motors and they said there was no recall on my Trailblazer, and I could contact my local Chevrolet dealer and see if they can tell me what I can do. I know what that information will be, bring it in and they will repair it, and that will cost me several hundred dollars. Thanks to general motors.

We purchased our 2003 Trailblazer ext used this summer. It had about 50,000 miles on it. We've noticed that when we're on the road for over 2 hours at a time, the speedometer becomes dangerously unreliable. Most recently, my husband was pulled over for an unsafe low speed -- until the state policeman saw that the speedometer was registering 20 miles an hour with the car in park and the engine turned off. We have had multiple failures. Resetting is sometimes possible by continually restarting the car, but not always, and not with any reliability. By continually restarting I'm talking 30-50 restarts. The wear and tear on the starter therefore is unacceptable. This vehicle should be covered by the recall, but we've not been notified and when we've taken it to dealerships, we haven't even been notified of the recall. The problem has no other discernible pattern and has happened approximately 6 times in the 8 months we've had the car.

Went out to start vehicle on September 18, 2004 - tuned key and nothing happened, no starter motor, no dashboard lights, nothing. Key remianed locked in steering column, could not be removed. Tried again the next morning (9/19) - same thing. Tried again the next morning (Monday, 9/20). The same thing - at that point called dealer to tow vehicle. About 3 hours later the tow truck came - tow truck operator got in vehicle turned key - and vehicle started right up just as if nothing was ever wrong! . Still had vehicle towed to dealership - dealer checked behicle over and found nothing wrong. On Saturday, October 23rd, came out of bank after running errnad, turned key in vehicle - nothing happened again. Kept turning key off and on for about 10 minutes until vehicle started out of the blue. Drove straight to dealer. Dealer replaced ignition switch. Vehicle worked fine until Sunday, January 23rd. Went to start vehicle and one again, nothing happened, no lights, no starter - nothing. Key also locked in steering column. Dealer towed vehicle the next day. Dealer could find nothing wrong, theorized an interior light was left on (but I know it wasn't). Dealer replaced some engine fan they theorize was turning on after engine turned off and draining battery - I told them that's fine but doesn't explain why truck will start days after an initial failure. This intermittent failure is frightening as it seems to be a possible part of a larger system failure - as noted on this website by other owners - when the Trailblazer will fail at high speeds on the highway. (reference odi id numbers 10101741 & 10060860).

My 2003 Trailblazer will not crank up all the time. It will not even turnover sometimes other times it will turn over and stop. This has happened on numerous occassions for the past 8 months. I beleive gm is waiting for the warrenty to expire. They have replaced my ignition system and fuel system. It still has problems with intermittent cranking. It has happened at the dealership and that is why my ignition system was replaced. Gm does not want to do anything. I have been stranded numerous times due to this problem. They got my money and that is all they care about. Please anyone I need help. Where else do I turn.

I have had several repairs done to my new vehicle. I have had the 2003 Trailblazer for 7 months and it has been in the shop 7 times-2 times for the coolant system-1 time for my master cylinder-3 times for my circuit boards-now for my steering and my starter( I believe my truck is in the shop as I am typing this letter) I have been trying to work with the dealership and gm but no one is trying to replace my truck with something that is not in the shop every month. Thanks.
