“The front passenger side seat belt was locking up on occasions didn't think much of it, but now it is locked up all together. The seat belt is inoperable, my family always wears a seatbelt, plus it is the law! Something needs to be done, I have done my research and this is a major problem with countless other 2003 chevy Trailblazer owners!”

“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. …”

“We purchase a new 2003 cherrolet Trailblazer august 16, 2003. We were on a trip when we had to trade our old 96 blazer in due to transmission problems. We had not gone 75 miles when our grandson somehow got the left rear seat belt wrapped around his waist, fortunately! I pulled over to the side of the road and had him carefully stand. My thinking was to ease the tension on the seat belt retractor mechanism. As I tried to loosen the tension the belt only became tighter and tighter around his waist until the buckle was starting to jab him in the abdomen. …”
