Known issues on the 1989 LeSabre. Two recalls apply to the 1989 LeSabre. On certain 1989 LeSabre vehicles, the left rear rocker panel could have poor welds that might let it deform enough for the left rear seat belt anchor to fall short of its required strength; a reinforcement kit was installed, and the recall covered 6 vehicles. Certain other cars may have left the factory without a fuel rollover valve, so fuel could spill in a rollover and feed a fire; the recall covered 1,655 vehicles. Owners logged 27 complaints, with fuel system, seat belts and vehicle speed control at 4 apiece; 2 reported a crash, 2 a fire and 1 an injury. Fuel system and body procedures, specifications and torque values follow.
