Complaints generally stated that one or both outboard rear seat belts do not retract at all and are useless.it is evident that the seat belts do not provide any tension and have excess slack.the retractor assembly has a plastic cover next to the retractor return spring.according to General Motors (GM), heat may soften, warp and deflect the plastic spring cover allowing the return spring to disengage through and jam in the spring cover access hole rendering the return spring nonfunctional.to elimanate the problem, GM changed the spring cover material and access hole at the beginning of production of model year (MY) 1996 Buick riviera and Oldsmobile Aurora vehicles.both complaints and warranty claims have declined significantly from MY 1995 subject vehicles to MY 1996 vehicles.
