2003 GMC Sierra 2500hd crew cab cloth split bench: the shoulder harness seatbelts on all three passenger seats will lock up during normal cruise (no sudden stops or yanks on the belts), and will continue to get tighter and tighter until the occupant must unbuckle the seatbelt and let it completely retract before it can be re-buckled. This will occur on nearly every trip in the vehicle, and has occurred since it was new. This is more than an annoyance, it is a safety hazard since the passengers must unbuckle their seat belts in a moving vehicle. The dealer (jim waldron GMC, davison mi) claims it is simply a design flaw and they can do nothing to correct it. They say that "everyone" with a 2003 Sierra is complaining about it. This problem never occurs on the driver side seat belt. I am seriously concerned for the safety of my passengers in this vehicle that is designed to carry many passengers.
I own a 2003 GMC Sierra crew cab truck. The rear seatbelts lock up and restrain my adult passengers to the point of discomfort. When the passengers try to pull out and release the locking mechanism, the seatbelt ratchets even tighter allowing no movement whatsoever. The seatbelts lock up while driving around town and more so on the highway during roadtrips. The result is that my adult passengers refuse to wear these belts. I have had these belts replaced once already. I took the opportunity to visit several dealerships, and inquired about this issue. I was told that there is a problem with gm's belts, but as of now all the dealerships are doing is replacing the belts for customers, yet the problem persist. It is my opinion that these belts were designed for car seats not adult passengers.
