CAMPAIGN: INOP. SEAT BELT MECH.- BUCKET SEATS (A95). GMC Truck GMC R Truck

Models: 1988 RV 10-20 Suburban with Bucket Seats (A95) and Gray Interior Trim (82I)

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada has determined that certain 1988 Suburbans equipped with bucket seats and gray interior trim may have an inoperable driver's seat and/or shoulder belt locking mechanism. In day-to-day usage of the lap/shoulder belt, a driver may not notice the problem. In the event of a crash, however, the affected belt(s) would not lock, but would totally unwind before it would restrain the driver, and therefore could increase the possibility of injury to the seat occupant.

To correct this condition, a new driver's seat belt assembly will be installed in each affected vehicle.

VEHICLES INVOLVED:

Involved are certain 1988 RV 10-20 Suburbans equipped with A95 and 82I built within the following VIN breakpoints:
