My Trailblazer once again would not start. I had it towed to a Chevrolet Dealer. They told me the ignition switch was bad. They replaced the switch, but about a week later the vehicle would not start. I once again had to use battery cables connected to another vehicle to start my car. I then took it back to the Dealer for repair. They then said I needed a new starter. I had the starter replaced, but this would later prove not to be the problem.

As soon as I bought this car from Autoland (Marcy,NY), for a pretty penny I might add, 13,000 worth of pretty pennies, I knew there was a problem. Within a week the car would just decide it wasn't going to start. Now, I came up with a way to get it going but it consisted of holding down the gas pedal hard until it turned over and it would always take two trys because when it turned over and revved the first time it would always die out so you would have to turn the keyy and rev it again, hold the gas down on insanely high rpms to be able to let go and hold an idle. Once it stayed running without holding the gas it would idle very high, stupidly high, 2 on the rpm scale or so. I didn't even have to use the gas pedal on take off the car will propel itself. The fan will run really loud and high. It is almost like your driving in four wheel drive low on dry roads but way worse. It will do this for days, but start normal, and then go back to a normal running car until it decides it does not want to start again. I have brought this car to the dealership for repair on several occasions to find and solve this problem (which they were well aware of when I purchased the car and promised to fix it upon purchase) but to no avale. It has been months and I was pushed off by these people for so long that they are now trying to tell me that I am out of their warranty. Every excuse in the book these people had until they finally said 'well it wont do it for us so we cant fix it'. Oh my god, I wanted to kill someone. Im now paying almost 500 dollar a month for a car that is scarily unreliable. Not to mention I call it the snap, crackle, pop car. I always feel like something is just going to fall off it. To wrap it up, I bought a crappy car for alot of money and the dealership wont honor there repairs. How do i go back in time and not sign those loan papers? I want out. Does anyone know how to get out of a car loan in this kind of situation?

Trailblazer LTZ

  • Automatic transmission

My parents purchased this vehicle for me in March 2008. On November 20, 2008 my Mom drove car to pick up my nephew from school around 2 pm. She came home parked the car and went to leave again at 4 pm and the car would not start. On December 5 I came home from college, the car still would not start. We took the battery out and took it for testing and was told the battery needed to be replaced. We put the new battery in vehicle but it still would not start. We had a mechanic look at it. Checked fuses etc could not find a problem. Car would not start. The only way he could get it started was to use a wrench to manually start it under the hood. I drove it back to college and it would not start again. I used the wrench under the hood to manually start it again. My sister is having the same problem with her 2004 Trailblazer.

Some people state that they have replaced the starter switch, alternator, but that it has something to do withthe security device, many people have reported the same problem but chevy has not done anything to solve this issue.
