Trailblazer EXT

  • miles


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.

Rear driver side door would not latch. No indication that door was opened. I have filed a complaint (ODI 10335683) about the passenger door that I repaired previously. This was the exact issue for recall 05007. The vehicle was brought in spring 2006. Obviously G.M.S "fix" is not working. Luckily this time the vehicle was in my driveway.

My rear passenger door opened while I was driving. The car was recalled in 2006 to supposedly fix this problem. We brought it in the spring of 2006 as per the recall. If my 9 year old daughter was not buckled in she would have fallen out of the vehicle. The recall was 05007.

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"

The contact owns a 2003 Chevrolet Trailblazer ext. The vehicle was repaired according to a recall, but the failure has recurred. The contact stated that the doors close and open intermittently. In addition, the latch does not lock properly on the rear passenger and driver's side doors, leaving them to remain unsecured. She placed her son in the child seat and closed the door, but it remained open. The contact had to push the door closed several times. Four months later, the failure occurred with the other door. The dealer and manufacturer stated that they could not assist. The NHTSA campaign id number was unknown. The failure mileage was 113,000 and current mileage was 120,000.

Three of the four door latching mechanisms had to be replaced in this truck. The doors would look like they closed but they would open as you turned a corner. This occurred twice when I had my kids in the truck, first on the passenger left side then a few months later the passenger right side. I am glad GM didn't screw up the seal belts too. This is dangerous.
