THE SAFETY INVOLVED HERE IS THE INABILITY TO CHANGE A TIRE IF IT FAILS ON THE ROAD. THE PLASTIC KEY AND INSERT ARE INADEQUATE FOR THE JOB. THE PLASTIC ON THE KEY GIVES AND THE LOCKING DEVICE ON THE HUB CAP BECOMES SO TIGHT THAT THE PLASTIC KEY WILL NOT REMOVE IT BEFORE FAILING. EACH TIME I HAVE HAD TO HAVE THE TIRES ROTATED OR CHANGED, THE MECHANICS REQUIRED AIR TOOLS AND 1 INCH SOCKET. ONE OCCASION OF A FLAT TIRE ON A TEXAS HIGHWAY PLACED MY WIFE AND I WITHOUT THE ABILITY TO CHANGE TO THE SPARE. HAD NOT A VERY HUSKY HIGHWAY PATROLMENT COME TO OUR RESCUE, WE WOULD HAVE BEEN STRANDED. IN THIS INCIDENT WE WERE ABLE TO GET OFF THE HIGHWAY ONTO A PRIVATE FARM ENTRANCE. MR

104V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
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.
Consequence & remedy
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.
