Summary
The Buick LeSabre has 19 recalls spanning the 1975–2002 production run, with the most serious recent issues being steering gear attachment bolts that can be missing or under-torqued on 2002 models, potentially causing complete loss of steering control, alongside a 2000 model year tie rod that can separate and send the car in an unexpected direction without warning.
The 2000 model year also has a brake hydraulic control unit with internal fluid leaks that can prevent anti-lock brakes, traction control, and stability control from functioning correctly when those systems are called on, raising the risk of losing control in demanding braking situations. A separate 2000 brake issue involves loose nuts connecting the brake booster to the pedal assembly, which can result in a low pedal, brakes that won't release, or complete brake failure if the nuts back off entirely. The 2000 model additionally has a headlamp horizontal adjuster that may not move the reflector during aiming, leaving the beam pointed in the wrong direction and reducing visibility. The 1999 model has a transmission detent lever retaining clip that can work loose and disconnect the linkage from the manual valve, causing the gear selector to show one position while the transmission is actually in another. Going back to 1997, front seatbelt buckles on some vehicles were assembled with incorrect parts that may not latch reliably in a crash.
On 1996 models, the upper intake manifold can crack during a backfire at startup, potentially causing an engine compartment fire and posing a risk to anyone near the open hood. The 1995 model year has a driver-side headlamp lens marked with an incorrect aim pad number, meaning any mechanical re-aiming using that number will leave the headlights aimed out of the correct range. The 1987 model has brake hydraulic unit mounting bolts that may be under-torqued, leading to soft pedal feel and, if the unit separates from its brackets, complete brake loss. The 1984 model has a rubber fuel return hose that can leak fuel while the engine runs, creating a fire risk that can reach the passenger compartment. The 1975 model, on vehicles fitted with heavy-duty steel wheels, has a center spider section that may not be properly welded to the rim, allowing the rim to separate from the wheel while driving and causing a sudden loss of control.
