I was wondering if anyone else owned a traiblazer or Envoy and have had the passenger seatbelt lock up for no reason. I thought that they were only supposed to lock up when you hit the brakes. And if you guys have had problems, has anyone taken it back to the dealer maybe for warranty work and have they been able to fix it. I just wanted to know before I decided to take our Extended Traiblazer in, since it will be the one I will be keeping longer, since we will be trading my Traiblazer in for the GTO. I am just tired of both trucks seatbelts it gets very annoying at times. Thanks for whomever can help.
