CERTAIN DELPHI FUEL PRESSURE REGULATORS, P/NOS. FP10020-11B1, FP10026-11B1, AND FP10027-11B1, SOLD AFTER JANUARY 9, 2007, AS AFTERMARKET EQUIPMENT FOR VARIOUS PASSENGER VEHICLES LISTED ABOVE. THE UNIVERSAL PRESSURE REGULATORS (UPR) WERE PRODUCED WITHOUT AN O'RING AND RETAINER.
THESE VEHICLES WERE ASSEMBLED WITH REAR OUTBOARD SAFETY BELT ANCHORAGES THAT MAY NOT WITHSTAND THE REQUIRED LOAD. THIS DOES NOT COMPLY WITH FMVSS NO.210, "SEAT BELT ASSEMBLY ANCHORAGES."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“DRIVING TOWARDS A STOPLIGHT AND THE BRAKE PEDAL WENT TO THE FLOOR ON A 1996 BUICK CENTURY. PUMPING GAVE ONLY PARTIAL REAR BRAKING. DROVE TO FRIEND'S HOUSE (DURING WHICH THE BRAKES WORKED NORMALLY THE WHOLE WAY). WE PULLED THE DRIVER SIDE TIRE AND DISCOVERED THAT THE FIBROUS FINELY WOVEN TUBE COVER (FIBERGLASS?) TO THE EXTREMELY THIN AND FRAGILE WIRES TO ABS SENSOR LOOKED BURNT. CUTTING IT OFF WE DISCOVERED THE WIRES INSIDE HAD SHORTED OUT. WHEN WE CLEARED THE SHORT AND INDIVIDUALLY WRAP INSULATED THE WIRES, THE ABS WARNING LIGHT THEN CAME ON. A GRAVEL SKID TEST REVEALED NO ABS AT ALL. WE FOUND THAT DEAD SHORTING THE WIRE TO THE SENSOR WITH A JUMPER WIRE WILL CAUSE THE ABS WARNING LIGHT TO GO OUT, BUT OBVIOUSLY DISABLES THE ABS. WE REPLACED THE SENSOR (WHICH REQUIRES THAT THE WHOLE BEARING/STUD ASSEMBLY TO BE REPLACED), AND THEN THE ABS LIGHT WENT OUT. A GRAVEL SKID TEST REVEALED THE ABS WORKING FINE AND HE SAYS THE NORMAL BRAKING IS NOW BETTER TOO. SOME RESEARCH REVEALS THAT THE ABS DETECTS NO TIRE TURNING DURING A SKID VIA THE SENSOR, AND RELEASES HYDRAULIC PRESSURE TO THE BRAKES UNTIL THE TIRE IS DETECTED BY THE ABS AS TURNING. WE THINK THAT WHEN A SHORT TO…”
“WHILE BACKING INTO MY DAUGHTER'S ATTACHED GARAGE, THE GAS LINE RUPTURED AND LEAKED A LOT OF GASOLINE BEFORE I SHUT-OFF THE IGNITION. I PROMPTLY RE-STARTED THE CAR AND BACKED IT OUT OF THE GARAGE, UNWITTINGLY RISKING IGNITING THE GASOLINE IN THE PROCESS, BUT STILL AFRAID OF THE GAS/FUMES IN THE GARAGE IGNITING AND BURNING US, THE CAR AND THE HOUSE DOWN! WE GOT A WATER HOSE AND BROOM AND SWEPT AS MUCH OF IT OUT OF THE GARAGE AS WE COULD. WE WERE LUCKY. THE POINT OF THIS COMPLAINT IS THAT THERE ARE PROBABLY TENS OF THOUSANDS OF G M CARS BEING DRIVEN AND PARKED IN GARAGES WITH QUITE OLD, DETERIORATING GAS LINES WHOSE DRIVERS ARE TOTALLY UNAWARE OF IT. OUR EXPERIENCE, ALONE, COULD HAVE BEEN A DISASTER. MY SON-IN-LAW HAS EXPERIENCED THE SAME PROBLEM WITH HIS 1995 OLDSMOBILE CIERA, ALTHOUGH HE BELIEVES THAT THE SQUIRRELS AROUND HIS HOME LIKE TO CHEW ON THE PLASTIC GAS LINES. IT SEEMS TO ME THAT THESE OLD PLASTIC GAS LINES REPRESENT AN ENORMOUS RISK TO THE SAFETY OF MILLIONS OF PEOPLE WHILE THEY'RE NOT EVEN IN OR NEAR THE SOURCE OF IGNITION. THEY COULD, IN FACT, BE IN BED AT THE OTHER END OF THE HOME WHEN IT ALL BLOWS-UP! *TR”
“I went to turn my wheel and it wouldn't turn left then the rack and pinion broke the wheel just turns 360 to the left but no movement in turning lost all steering”
