Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 1991 BUICK Century. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
THE POWER SEAT OR RECLINER WIRING HARNESS CAN BE PINCHED OR CAN CHAFE ON THE SEAT FRAME OR SPRING SUPPORT ROD, WEARING THROUGH THE WIRE INSULATION AND CAUSING AN ELECTRICAL SHORT.
Consequence
THE HIGH CURRENT CAUSED BY THE ELECTRICAL SHORT WELDS THECIRCUIT BREAKER ELEMENTS TOGETHER IN THE CLOSED POSITION, LEAVING THE CIRCUITUNPROTECTED AND GENERATING SUFFICIENT HEAT TO BURN THE WIRE INSULATION ANDIGNITE THE SEAT CUSHION MATERIAL.
Remedy
REPAIR ANY ABRADED WIRING AND REROUTE THE WIRING HARNESS USING A WIRING HARNESS CLIP.
THESE VEHICLES WERE ASSEMBLED WITH REAR OUTBOARD SAFETY BELT ANCHORAGES THAT MAY NOT WITHSTAND THE REQUIRED LOAD. THIS DOES NOT COMPLY WITH FMVSS NO.210, "SEAT BELT ASSEMBLY ANCHORAGES."
Consequence
CONSEQUENCE OF NON-COMPLIANCE: IN A COLLISON, STRESS CAN CAUSE THE ATTACHMENT METAL TO TEAR AND ALLOW THE ANCHORAGE TO SEPARATE FROM THE BODY OF THE VEHICLE. THE SAFETY BELT MAY NOT PROTECT AN OCCUPANT IN THE EVENT OF A VEHICLE CRASH.
Remedy
DEALERS WILL REPLACE THE EXISTING ANCHOR BOLTS WITH A NEW SHOULDER BOLT AND THREAD LOCKING ADHESIVE. ADDITIONALLY, NOISE CONTROL PATCHES WILL BE APPLIED AT EACH ANCHORAGE.

Complaints across nearby Buick Century model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
