VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES DO NOT CONFORM TO THE REQUIREMENTS OF FMVSS NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT." THE HEAD LAMP ADJUSTMENT DEVICE HORIZONTAL ADJUSTER MAY NOT MOVE THE HEAD LAMP REFLECTOR WHEN THE SHAFT IS ROTATED IN A NORMAL MANNER DURING AIMING.

DRIVER VISIBILITY MAY BE IMPAIRED INCREASING THE RISK OF A CRASH.

AN INSERT CONTAINING INSTRUCTIONS FOR OPTICALLY AIMING THE HEADLAMPS WILL BE PROVIDED TO OWNERS FOR THE OWNER'S MANUAL. OWNERS SHOULD FOLLOW THE PROCEDURE IN THE INSERT FOR HEADLAMP AIM ADJUSTMENT, RATHER THAN USING THE HORIZONTAL VHAD INDICATOR.

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE BRAKE BOOSTER TO PEDAL ASSEMBLY ATTACHMENT NUTS MAY BE LOOSE.

IF THESE NUTS ARE LOOSE, THE BRAKE PEDAL MAY BE LOW, THE ASSEMBLY MAY BE LOOSE, THE BRAKES MAY NOT RELEASE, AND IF THE NUTS BACK COMPLETELY OFF, BRAKING MAY BE LOST. ALSO FUME AND WATER INTRUSION TO THE PASSENGER COMPARTMENT CAN OCCUR.

DEALERS WILL REPLACE ANY MISSING BRAKE BOOSTER TO BRAKE PEDAL ASSEMBLY NUTS AND TIGHTEN ALL FOUR (4) NUTS TO SPECIFIED TORQUE.

VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THESE VEHICLES HAVE INTERNAL FLUID LEAKS IN THE BRAKE HYDRAULIC CONTROL UNIT.

WHEN THE REAR BRAKE PROPORTIONING, ANTILOCK BRAKE, TRACTION CONTROL, OR STABILITY CONTROL FEATURE IS ACTIVATED IN SOME DRIVING SITUATIONS, THE FEATURE MAY NOT PERFORM AS DESIGNED.

DEALERS WILL INSPECT THE ABS HYDRAULIC MODULATOR UNIT AND IF NECESSARY, REPLACE THE HYDRAULIC MODULATOR.

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE INNER TIE ROD NUTS ARE LOOSE AND CAN RESULT IN SEPARATION OF A TIE ROD.

SEPARATION OF A TIE ROD CAN CAUSE UNEXPECTED STEERING INPUT INCREASING THE RISK OF A CRASH.

DEALERS WILL CHECK AND ADJUST THE VEHICLE TOE-IN AND TIGHTEN THE INNER TIE ROD NUTS TO THE SPECIFIED TORQUE.

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.

THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.

DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
