Buick LeSabre Recalls

Summary:
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Summary:
CERTAIN PASSENGER, MINI VANS, AND SPORT UTILITY VEHICLES HAVE AN AIR BAG INFLATOR ON THE DRIVER'S SIDE THAT COULD FRACTURE AT A WELD DURING A DEPLOYMENT.
Summary:
CERTAIN PASSENGER VEHICLES WERE BUILT WITH MISSING OR UNDER-TORQUED STEERING GEAR ATTACHMENT BOLTS. IF A BOLT IS MISSING, THE DRIVER MAY NOTICE UNEVEN STEERING RESPONSE OR UNUSUAL NOISES DURING TURNS.
RepairPal Expert Overview:

The adjuster screws for the headlamp reflector aiming do not function properly, which can impair driver visibility. Buick will provide updated instructions to vehicle owners regarding headlamp aiming.

RepairPal Expert Overview:

The anti-lock brake system hydraulic control unit (HCU) may leak brake fluid. A brake fluid leak may compromise braking ability, which could result in an accident. Dealers will inspect and replace the HCU if necessary.

RepairPal Expert Overview:

The inner tie rod nuts may be loose. This may cause detachment of the steering linkage and a loss of steering control. Dealers will inspect and secure the tie rod nuts. Dealers will also check and adjust the toe setting of the wheel alignment.

RepairPal Expert Overview:

The brake pedal to pedal assembly attachment nuts may be loose, which can cause a low brake pedal and a compromised brake system operation. Dealers will replace any missing brake booster to brake pedal assembly nuts and tighten all four nuts to the specified torque.
