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.
Summary
Certain vehicles do not comply with the requirements of CMVSS 1101 - Emission Device. Vehicles were built with incorrect emission control labels. The emission control (tune up) labels have an incorrect emission vacuum hose routing schematic. Correction: Dealers will install a new vehicle emission control label on the radiator support.
Summary
Certain vehicles do not comply with the requirements of CMVSS 102 - Transmission Shift Control Sequence. A retaining clip which secures the manual valve to the linkage of the transmission detent lever, may become loose and allow the link to become disconnected from the manual valve. If the link disconnects, the driver's indicated 'PRNDL' state may differ from the hydraulic state of the transmission. This does not affect the 'PARK' position, but if a driver selects 'DRIVE' and the transmission is actually in 'REVERSE', a crash could occur without warning. Correction: Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
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.
Summary
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH 4T65E AUTOMATIC TRANSMISSIONS. THESE VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FMVSS NO. 102, "TRANSMISSION SHIFT LEVER SEQUENCE." A RETAINING CLIP, WHICH SECURES THE MANUAL VALVE TO THE LINKAGE OF THE TRANSMISSION DETENT LEVER, CAN BECOME LOOSE UNDER A COMBINATION OF POSSIBLE DRIVER SHIFTING MANEUVERS AND ALLOW THE LINK TO BECOME DISCONNECTED FROM THE MANUAL VALVE.
Potential Consequence
IF THE LINK DISCONNECTS, THE DRIVER'S INDICATED PRNDL STATE MAY DIFFER FROM THE HYDRAULIC STATE OF THE TRANSMISSION. IF THE DRIVER SELECTS 'DRIVE' AND THE TRANSMISSION IS ACTUALLY IN 'REVERSE', A VEHICLE CRASH COULD OCCUR.
Remedy
DEALERS WILL REPLACE THE MANUAL VALVE/LINK ASSEMBLY WITH A REPLACEMENT MANUAL VALVE/LINK KIT, FEATURING A SPRING-TYPE FASTENER.
