2001 GMC GMC User Comment / Complaint

The passenger side front seat belt tightens up continuously when worn. as a consequence, the belt is useless and unusable. i have attempted to get it repaired 3 times at two different dealerships to no avail. i know of two othe vehicles with the same problem. the service manager at the dealership says that his vehicle has the same problem. the manufacturer tells me there is no fix available. this is a serious safety deficeiency and should be addressed on this very high volume vehicle (suburban, denali, tahoe etc..)
