FUEL SYSTEM, GASOLINE:DELIVERY
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.
Potential Consequence
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.
Remedy
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.
Engine
Summary
On certain vehicles, a combination of a low battery condition and fuel in the upper intake manifold while the ignition key is activated at engine start could cause an elevated rate of manifold over-pressurization events. The operator may experience a loud bang / intake backfire that could rupture the intake manifold, resulting in emitting dust from under the hood and a no-start condition. If this event were to occur, and if an ignition source were present, an engine compartment fire could occur. Correction: Dealer will replace the fuel pressure regulator.
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS
Summary
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THESE VEHICLES HAVE INTERNAL FLUID LEAKS IN THE BRAKE HYDRAULIC CONTROL UNIT.
Potential Consequence
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.
Remedy
DEALERS WILL INSPECT THE ABS HYDRAULIC MODULATOR UNIT AND IF NECESSARY, REPLACE THE HYDRAULIC MODULATOR.
Brakes
Summary
Certain vehicles may 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 and the driver could lose vehicle control. Correction: ABS hydraulic modulator unit will be inspected and replaced if necessary.
EXTERIOR LIGHTING:HEADLIGHTS
Summary
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.
Potential Consequence
DRIVER VISIBILITY MAY BE IMPAIRED INCREASING THE RISK OF A CRASH.
Remedy
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.
Lights And Instruments
Summary
Certain vehicles do not comply with the requirements of CMVSS 108 - Lighting Equipment and Retroreflective Devices. The vehicle headlamp adjustment device (VHAD) horizontal adjuster may not move the headlamp reflector when the shaft is rotated in a normal manner during aiming, and the owner's manual does not contain any instructions for visual/optical aiming of the headlamps. Correction: Dealers will install an insert in the owner's manual insert containing the correct information.
Steering
Summary
On certain vehicles, the inner tie rod nuts may be loose, which could result in separation of a tie rod. Separation of a tie rod could cause unexpected steering input in some maneuvers and could cause a crash without prior warning. Correction: Dealers will check the torque of the inner tie rod nuts and if necessary, adjust the vehicle toe-in and tighten the inner tie rod nuts to the specified torque.
STEERING:LINKAGES:TIE ROD ASSEMBLY
Summary
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE INNER TIE ROD NUTS ARE LOOSE AND CAN RESULT IN SEPARATION OF A TIE ROD.
Potential Consequence
SEPARATION OF A TIE ROD CAN CAUSE UNEXPECTED STEERING INPUT INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL CHECK AND ADJUST THE VEHICLE TOE-IN AND TIGHTEN THE INNER TIE ROD NUTS TO THE SPECIFIED TORQUE.
SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM
Summary
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE BRAKE BOOSTER TO PEDAL ASSEMBLY ATTACHMENT NUTS MAY BE LOOSE.
Potential Consequence
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.
Remedy
DEALERS WILL REPLACE ANY MISSING BRAKE BOOSTER TO BRAKE PEDAL ASSEMBLY NUTS AND TIGHTEN ALL FOUR (4) NUTS TO SPECIFIED TORQUE.
