I've had to replace the transmission twice now I have in fact reported to gm asking if there was any recourse I may take and they simply flat out told me no! so I started hearing a noise and then the transmission started to not shift properly to the point you could not drive it. To me this I consider this a very unsafe condition because if it stopped moving altogether I'd be on the highway with the possibility of an accident occurring. I do have an invoice but no scanner, it did cost me 3k or better on both occasions to replace it. I'd like to know if there's anything I'm able to do to be reimbursed for any or all of the inconvenience I've concurred.

I purchased a 2002 Chevrolet Trailblazer from younger Toyota in hagerstown, MD on may 12, 2007. Approximately a week and a half afterwards, I contacted the salesman that sold us the vehicle, phil young, complaining that the transmission was making a noise and the vehicle wasn't shifting correctly. He told me to bring it in to the service department. My husband (not car savvy) said that the noise was coming from the underside of the Trailblazer and felt it might be the brakes causing the noise and jerking. I stuck to my guns that it was the transmission and wanted it repaired while it still had the 30 day warranty. Younger denied it was the transmission and noted my husband's theory of the brakes, but nothing about my complaint concerning the transmission. The Trailblazer was taken back 2 or 3 more times to the service department, we demanded they fix it. The Trailblazer sat in their lot for three weeks because we would test drive it and bring it right back stating that the problem was still there. On or around January 14, 2008 the Trailblazer broke down in charlestown, wv. We took it by creamers automotive, they asked what the symptoms were and the mechanic drove around the block with me, instantly stated that it was the sunshell in the transmission and that they had someone in earlier that week with the same problem. They had purchased their vehicle at younger automotive as well and they denied the transmission problems and wouldn't note it on their paperwork as well. In my research of this problem, I found it to be very widespread, there are hundreds of complaints on one website alone. The sunshell is a faulty part that should be recalled by gm. Someone is going to be hurt or even killed if this isn't taken care of immediately. Gm is fully aware of this problem, there have been hundreds, maybe even thousands of complaints on this particular vehicle and should take ownership of a product they produce and sell.

I had several instances of the engine revving up before the vehicle would shift. These were usually when the engine was cold so I assumed that was the problem. However 5 days ago the transmission went out. The engine revved really loud, the tach number went way up, suddenly the vehicle clunked & jerked into gear it then made a whining noise & when I got home (drove it real slow & not far from home) there was no reverse. Chevrolet says there is not a problem with these transmissions & they have not received very many complaints on this problem. My transmission repair shop told me this is the third one in 3 weeks with the exact same problem. Chevrolet is refusing to do anything about this. There are numerous web sites full of postings of people with the same problem.

Loud clanking noise coming from the rear to center of the vehicle when shifting from park to forward or reverse, ieee when lack of or direction is changed. 36,000 miles, very poor quality vehicle as I have had several other issues.

Purchased new Trailblazer in may 04. When vehicle had approximately 3,000 miles on it, I started getting a rattle or loud buzz when accelerating at approximately 25 per hours just before the vehicle shifts. Occasionally, the shift if jerky. The vehicle has to be warm and the rattle or buzz first manifested itself after I turned right and accelerated from a stop. When warm, this sound is repeated almost every time I turn right and accelerate. When warm is also occurs when I just accelerate from a full stop. Occasionally, it will also occur after a tight left turn. I reported it to the dealer and they told me the computer did not show anything wrong. On the second trip to the dealer I reported it again. Still no fix. The noise is very annoying, but I cannot tell that it is doing damage. I certainly would not have bought this vehicle if it made this noise on the road test. I am estimating the rattle or buzz sound has occurred at least 75 time to date.

Purchased a new 2003 chevy Trailblazer and 3 days later delivery the check 4wd light came on for service. We were in maine at the time and had it looked at by a chevy dealer there & they assumed it was an electrical malfunctionwith a code so all they did was reset the computer (or s we were told) a few days later the transmission downshifted hard. The dealer recommended that we drive it awhile. It did the same noise on & off for a few months & they still couldn't find anything wrong. Much later on after my frustration with the dealership. I started to get a loud clunking sound in the front end noticeably on the right side of the vehicle. Dealer said it was the plastic cowling in the front that was rattling. After taking it to an independent repair shop they discovered that the transmission end bearing out of the front axel is n/g & it needs to be rebuilt. This is not acceptable,especially after all the complaints of this transmission on the gm trucks. Why has there not been a recall on this is beyond me.
