I was at work on 8-18-2011 when co workers asked me if I had a black Chevy trailblazer because someone saw my rear window explode. I went outside and there was glass all over the ground outside and my window was broken in little pieces. I came home and searched the web for similar problems. I found this had happened to other people and there was a number to contact the manufacturer. I called them but they told me there aren't any open recalls pertaining to this type of problem.

While changing lanes on the freeway, my tailgate window shattered on my 2003 Chevy Trailblazer ext. There were no warning signs of this event. There were no chips in the glass, the road was smooth. Since the glass has shattered the tailgate lock mechanism is now malfunctioning as well.

Purchased a 2003 Chevy trailblazer-ext lt in Dec 2002 from the dealer, team Chevrolet in pasadena. Since purchasing the vehicle, there's been several recalls, one in particular that keeps recurring are the brake lights keep burning, the dealer changed both units but it keeps burning out. I got tired of taking it to the dealer, so I purchased new bulbs and looked into replacing them myself. However when I unscrewed the bulb, I noticed the bulb just didn't burn normally (like a home lamp) it looked more of an electrical issue, the lining of where the bulb is screwed in looked like it had white residue and it smelled smoky. Also, don't know if its the shocks or suspension, makes odd noises. Dealer said its fine, but the noise is still there.shorly after my engine light turned on...the dealer could not figure what was wrong after a 2 to 3 week and costly expense and time...they switched out the gas tank...come to find out, that wasn't the problem, the engine light turned on again, they said one of the pistons needed replacing...$$$ that was a big expense and time consuming... everytime I took it to them it, something was fixed, they charge, I pay, and the engine light would turn on, it got frustrating. Till, they finally got it right. Now my car sounds horrible (shocks/suspension noise got worse) when I go over city bumps or driving even small like hills, and mind you, which is driven by myself (female 124lbs) it shouldn't squeak or make noises, the brakes pedal makes a noise when I place my foot on it....yes it has 90K miles and it's an 8 year old car, but I kept up with the maintenances, I've taken it to the same dealer since it was purchased, only drive it to and from work....the car is in good condition, no hit/scratches/no tears.... I can't explain why.... are there any other recalls, the dealer isn't aware of"?? for instance they were not aware of the gas tank recall..which they were charging me over $1200 to repair, how can I trust they are doing their job"

My speedometer in my 2003 Chevrolet trailblazer stopped working, all the other instruments work. This is not safe. I did some research and found that a number of complaints have been filed on this very issue. GM should replace this part. It appears they knew there was a problem.
