“We have a seat belt that does not work. It stopped working a few days ago and so we cannot go anywhere as a family. The seat belt is stuck and will not come out at all. Not only that, but we have another seat belt that has been broken for years. Everytime I mention this like this to the chevy dealer, they want to charge me and arm and a leg and will not work with me. Seat belts should not break. The people at Chevrolet should cover at all times something as serious as this but they simply do not care! Do not buy a chevy!”

“Driver's seat belt will not release. Bought brand new in 2004 and happened while driving off the car lot. Has since been replaced just once, but problem continued. Up until 2 months ago, seatbelt would release shortly, but now it has been stuck for 3 weeks. Trying to get GM to replace, but they have just now agreed to pay 50%. Previously when it was replaced it was a major safety issue of theirs and I was not allowed to drive it at all. This time, since it is out of warranty, they have not made an attempt to put me in another vehicle or offer to fix it. …”

“I bought vehicle in october 2003. It is a 2004 Chevrolet Trailblazer. In the months following I began having electrical problems . Check engine light would flash on and then went off again. The first time it happened car stalled as well. I would bring it in to the dealership and they would say that they could not duplicate the problem, and they hooked up to the computer and didn't find any problems. I also had my headlights flicker when accelerating and decelerating. I have had numerous problems with my blinkers. I have had the tail light assemblies replaced twice. …”

“The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the vehicle was parked when he attempted to install a child safety seat in the third row seating, but none of the seat belts would successfully tighten and retain the child seat. The vehicle was not taken to have the failure diagnosed or repaired. The contact also stated that the headlights were experiencing a recurring failure in which they would periodically burn out. Upon examining the headlight housing, the contact noticed that the wires were burned. …”

“The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the front driver's side seat belt is inoperative. The mechanism that allows the seat belt to safely position the strap onto the passenger does not retract; therefore, the seat belt harness is extremely loose. In the event of a crash, the occupants would not be properly restrained, which increases the risk of a serious injury. The manufacturer did not provide any assistance. The failure and current mileages were 61,000.”
