CAMPAIGN SEAT BELT BUCKLES

Models: 1988 Optima

General Motors of Canada has determined that a defect which relates to motor vehicle safety may exist in certain 1988 Optima Model vehicles. The seat belt buckles on these vehicles may not properly latch. It could appear to the occupant(s) that their seat belt buckle is latched, but the latch plate can be removed from the buckle without pressing the release button. In the event of a sudden vehicle stop or collision a seat belt buckle with this condition could release, increasing the risk of injury to those occupants.

To prevent the possibility of this condition occurring, the seat belt buckles will be replaced with new buckles on all involved vehicles.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
