The contact owns a 2003 Chevrolet Trailblazer. While driving approximately 35 mph, the vehicle slid on ice and crashed into a cement wall. The air bags did not deploy and the seat belt did not restrain the contact. The contact sustained chest, neck, and knee injuries that required medical attention. A police report was filed. The vehicle was driven to the contact's residence. The vehicle was then taken to an independent mechanic, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 70,000.

I was on highway I25 sb in denver, co. Middle lane, clear conditions, 30-35 mph. 4 cars in front stopped short, I came to a stop as soon as I could, missing the car in front by an inch. A van behind me rear ended me going approx 30mph. I am 5'1 so my head hit the steering wheel causing a concussion. My complaint is that neither my seatbelt nor my front passenger's locked into position. My passenger's seat even rocked back rendering her spine completely unstable. Airbags did not deploy and we did not feel safe. My vehicle is totaled.

I purchased my Chevrolet trail Blazer new in 2003. Soon after, my driver's seatbelt began to lock up and would not release in order to put it on, leaving me to drive without wearing a seatbelt. I notified the dealer of the problem. Over the past 5 years they have replaced the seatbelt, frame, or mechanisms 5 times. I have 15 documented times of issues with the seatbelt. This does not include all the phone calls or hundreds of times it locked up that I eventually got it unlocked myself. I called and wrote their customer service department. The dealer finally found a document they presented me dealing with the issue which states you have to get out of the car and press in certain areas to release the belt. Sometimes this works, sometimes I am unable to get it to release and must drive without a seatbelt. This is illegal in my state and punishable by a ticket and fine. I have begged for help to no avail with the dealer who says they are sorry. I searched online and this seems to be a problem for others as well.

I am having a issue with GM on the child comfort guides, or lack of, on our 2003 Trailblazer. On page 1-27 of the owners manual it shows a comfort guide that is suppose to be located in a pocket on the side of the seat. I have talked to 3 dealers and a rep at my-GM link. The dealers did the best that was possible but I feel that the information the rep at my-GM link provided would cause a safety hazard. Apparently GM has a kit that could be installed by attaching a bracket with a tether and a clip that hooks around the seat belt to provide the function of the comfort guide. If this tether is in place it would block exit from the rear seats because it connects to the side of the vehicle and would stretch across the exit once the middle seat is folded down, and could possibly be a trip hazard. We have two young children and the belt goes right across their face and causes a problem when they keep trying to place the shoulder strap behind their back. I feel this comfort guide is essential in providing safety for young and short passengers. The case number with GM is 1-94348313. I would appreciate any help with this matter.
