THE SUB FRAME (SOMETIMES CALLED ENGINE CRADLE) BUSHINGS, RETAINERS, AND THE SUB FRAME ITSELF WHEREIN THEY MOUNT, ARE DECAYED. SOME BUSHINGS AND RETAINERS ARE COMPLETELY MISSING. HAVING INVESTIGATED THE REQUIREMENTS FOR REPAIR, I HAVE FOUND THAT NEARLY ALL GM CARS WITH THIS MOUNTING SYSTEM ARE EXPERIENCING THE SAME MALFUNCTION. THIS IS DEFINITELY A SAFETY ISSUE, IN THAT THE ENGINE CRADLE CAN FALL FROM THE VEHICLE. IN MY OPINION THIS IS THE RESULT OF A DESIGN OR MATERIALS FAILURE, INCORPORATED WHEN THE VEHICLE WAS MANUFACTURED.THE REPAIR COST OF THE PARTS, FROM GM "DEALER ONLY", IS PROHIBITIVE. IS THIS BEING CONSIDERED FOR A MANDATORY RECALL.?

TL*THE CONTACT OWNS A 1998 BUICK LESABRE. THE CONTACT STATED THAT THE BRAKES WERE APPLIED YET THEY DID NOT RESPOND. THE VEHICLE PROCEEDED TO CRASH INTO A ROW OF HEDGES. THE CONTACT WAS NOT INJURED. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR FACILITY WHERE THE CONTACT WAS INFORMED THAT THE BRAKE LINE WAS COMPLETELY RUSTED. THE MECHANIC REPLACED THE BRAKE LINES. IN JUNE 2010, THE CONTACT NOTICED ABNORMAL FRONT END NOISE. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR FACILITY WHERE THE CONTACT WAS INFORMED THAT THE STABILIZER BAR BUSHINGS HAD FRACTURED FROM THE VEHICLE AND THE BUSHINGS UNDER THE CRADLE WERE EXTREMELY RUSTED. THE BUSHINGS WERE REPLACED IN BOTH AREAS. THREE MONTHS LATER, THE CONTACT NOTICED FUEL LEAKING FROM UNDER THE VEHICLE ABNORMALLY. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR FACILITY WHERE THE CONTACT WAS ADVISED THAT THE FUEL SENDING UNIT WAS DEFECTIVE AND WOULD NEED REPLACING. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 119,000 AND THE CURRENT MILEAGE WAS APPROXIMATELY 120,000.

Structure
LEFT AND RIGHT DOOR SEALS (WEATHER STIP) FAILED. MJS
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.
