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.
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.
AS I WAS DRIVING FROM THE GAS STATION I TOOK A LEFT AND AS I ACCELERATED, THE ENGINE STARTED TO VIBRATE. I I HAD NEVER NOTICED THIS BEFORE THAT DAY. SO PROCEED TO TAKE MY TIME CAREFULLY BACK TO WORK. I EXAMINED THE UNDERCARRIAGE OF MY 99 LESABRE CUSTOM AND THAT'S WHERE I NOTICED THAT THE DRIVERS SIDE SUBFRAME BUSHINGS HAVE ALL BUT FELL OUT DUE TO SEVERE RUST. THANKFULLY THE PASSENGER SIDE IS STILL FIRMLY ATTACHED. UPON FURTHER RESEARCH, THIS IS A COMMON PROBLEM WITH GM CARS OF THIS ERA AND THE DORMAN REPLACEMENT PARTS ARE READILY AVAILABLE. HAD THIS COMPONENT FAILED ON BOTH SIDES THE ENGINE AND TRANSMISSION WOULD HAVE FALLEN OUT AND CAUSED AN ACCIDENT OR WORSE. I AM STILL TRYING TO FIGURE OUT IF THIS IS A RECALL ISSUE OR JUST A BAD CHOICE OF VEHICLE DESIGN BY GM AND THEIR LACK OF CONCERN FOR THE PUBLICS WELL BEING. THESE SUBFRAME BUSHINGS SHOULD HAVE BEEN OR SHOULD BE A VIABLE RECALL CONCERN TODAY. THANK YOU FOR YOUR CONSIDERATION IN THIS MATTER.

I WAS SITTING AT A RED LIGHT WHEN MY AIR BAG FROM THE STEERING COLUMN DEPLOYED IN MY FACE. I DID NOT HIT ANYTHING. IT WAS ON OR ABOUT 1/25/18. ABOUT A WEEK PRIOR TO THIS EVENT MY HORN BEGAN TO STEADILY BLOW INEXPLICABLY. I DID NOT HAVE ANY REASON TO SUSPECT ANYTHING OTHER THAN A MALFUNCTIONING HORN SO I DISCONNECTED THE WIRES TO THE HORN. WHEN THE AIR BAG DEPLOYED ABOUT A WEEK LATER I CONCLUDED THE AIR BAG WAS INFLATING INSIDE THE STEERING WHEEL APPLYING PRESSURE TO THE HORN SENSOR. I TOOK IT TO THE DEALER WHO, AFTER WEEKS OF INVESTIGATION, CONCLUDED THEY COULD NOT DO ANYTHING TO REPAIR IT AND SUGGESTED I CALL GENERAL MOTORS CUSTOMER ASSIST CENTER. AFTER REVIEWING PICTURES, (NO ONE ACTUALLY PHYSICALLY LOOKED AT IT) GM DECIDED CORROSION TO THE SENSING MODULE CAUSED THE PROBLEM. I CONTEND THEY HAVE A DEFECTIVE VALVE WHICH OVERTIME BEGAN LEAKING GAS INTO THE AIR BAG, HENCE THE ISSUE WITH THE BLOWING HORN.

TL* THE CONTACT OWNS A 1999 BUICK LESABRE. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT WAS ABLE TO RESTART THE VEHICLE 5 -10 MINUTES LATER. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE FUEL PUMP WAS MALFUNCTIONING. THE FUEL PUMP WAS REPLACED. AFTER THE FUEL PUMP REPLACEMENT, A STRONG FUEL ODOR WAS DETECTED IN THE VEHICLE WHILE DRIVING OR PARKED. THE VEHICLE WAS TAKEN BACK TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE FUEL RING WAS CAUSING THE FUEL ODOR. THE RING WAS REPLACED, BUT THE ISSUE PERSISTED. THE CONTACT TOOK THE VEHICLE BACK TO THE INDEPENDENT MECHANIC WHO STATED THAT THE FUEL TANK AND FUEL NECK WERE THE POSSIBLE CAUSE OF THE CONTINUING FUEL ODOR, AND BOTH PARTS NEEDED REPLACEMENT. THE CONTACT HAD THE FUEL TANK AND FUEL NECK REPLACED, BUT THE FUEL ODOR CONTINUED. THE MANUFACTURER AND THE LOCAL BUICK DEALER WERE NOT MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS APPROXIMATELY 200,000.
