2007 Chevrolet Silverado 1500 lighting problems

Driving down a paved road at apx 40 miles an hour and heard a loud sound like a shot gun going off, my driver side seat belt clamped down and the flashers on the truck turned on. Startled I pulled over and had to struggle to get the seat belt off. Had to shut off and restart vehicle, now seat both driver and passenger side won't work, they are locked in position. After contacting local dealer I was told I needed a new airbag control module and I had to replace both seat belts.

Tl*the contact owns a 2007 chevrolet silverado 1500. The contact stated that the brake lights would operate until the brake pedal pressure was reduced. The failure occurred at any speed. The dealer replaced the brake switch. The service manager stated that this was normal operation. The current mileage was 5,700 and failure mileage was 2,500.
