Cranked my truck yesterday and put it in drive. Slowly drove about 300 feet and the pretensioner-??s discharged in my seatbelts. I fortunately did not have it on yet, but the seatbelts are now unusable.

I was slowly going across a parking lot when a loud bang like a gun shot happened and the driver side seat belt pulled me tight against the seat. There was a smell of a chemical gas in the cab and the emergency flashers came on. I am surely glad I was only going a few miles an hour. Now the seat belts (both sides) are locked tight. I understand this might not be that rare of a problem but it's the first I've ever heard of it.

My husband was stopped at a light when the side airbags deployed. We contacted GMC they sent someone to investigate. That person said due to some water leaking in on them is what caused it. Nothing was wet though. Now they cannot do anything to help. Seems like if they know they have a defect in the front airbags it is a chance the side ones are also bad. They hang like curtains. Have not been able to drive it since the seatbelts locked also. The cost to repair would be $6000. This is something that was no fault of ours. There has been so much time put into trying to get this resolved. We cant E the only ones this happened to. Suggestion?

My service man was pulling out of parking lot at store when air bags exploded and seat belts locked. He did not hit anything and was only going about 10 mph when this happened. Took to local dealer to see if they could fix it. They said yes, but we would have to pay for it. We could contact the manufacturer if necessary. The bill was $1413.89. (parts $798--labor $562.59 tax 48.19). We had to get it fixed as it is illegal to be on the road without seat belts (or air bags). We feel these are defective parts an D we should be reimbursed by the manufacturer.. this is an unsafe vehichle!!!! thanks

Drivers side seat belt will not lock in to the receiver on side of seat. Dealer said I may have to pay for a diagnoses and replacement plus parts. I say it's a safety issue and should be covered for free. Wonder if other people have had same problem.
