NHTSA complaint #10066488, filed 2004-04, 100 miles“I own a 2003 Gmc Sierra crew cab truck. The rear seatbelts lock up and restrain my adult passengers to the point of discomfort.

I have had these belts replaced once already. I took the opportunity to visit several dealerships, and inquired about this issue. …”
