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.
CERTAIN DELPHI AFTERMARKET FUEL PUMP MODULES / MODULE RESERVOIR ASSEMBLIES (MRA) THAT WERE SOLD FOR USE ON THE ABOVE LISTED VEHICLES. DURING PRODUCTION THE MRAS VENT AND FUEL RETURN TUBES WERE REVERSED. THIS CONDITION CAN RESULT IN THE VEHICLE NOT RUNNING CORRECTLY (IDLE ROUGH AND/OR STALL) DUE TO AN OVERLY RICH FUEL BLEND OR THE VEHICLE'S EVAPORATIVE EMISSION CARBON CANISTER MAY LEAK FUEL.
ON CERTAIN PASSENGER VEHICLES. IF THE ENGINE FAILS TO START AND THE DRIVER HOLDS THE KEY IN THE "START" POSITION FOR AN EXTENDED PERIOD, HIGH CURRENT FLOWS THROUGH THE IGNITION SWITCH, AND SOMETIMES PRODUCES ENOUGH HEAT TO MELT INTERNAL SWITCH PARTS.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“WHILE APPLYING THE BRAKES, THE PEDAL WENT TO THE FLOOR. THE DRIVER WAS ABLE TO STOP. THE CONSUMER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE AND DROVE IT TO THE DEALER FOR INSPECTION. THE MECHANIC INFORMED THE DRIVER THAT THE BRAKE PADS AND FRONT ROTOR NEEDED REPLACE DUE TO CORROSION. PLEASE FILL IN ADDITIONAL INFORMATION. *JB”
“WAS DRIVING ON INTERSTATE 287 IN NEW JERSEY WHEN ENGINE CUT OFF CAUSING LOSS OF BRAKES, POWER STEERING. CAUSED ACCIDENT WHEN RAN OFF ROAD DUE TO LACK OF POWER STEERING AND INABILITY TO EFFECTIVELY BRAKE. TOOK TO DEALER WHO REPLACED CRANKSHAFT SENSOR THAT DID NOT REPAIR PROBLEM. AFTER CAR WAS REPAIRED INCIDENT CONTINUED TO OCCUR WITHOUT ANY TROUBLE CODES. NOW THAT ISSUE HAS DEVELOPED WITH IGNITION SWITCHES, IT SEEMS TO ME THAT THIS MAY BE A LONGER TERM PROBLEM THAN CURRENTLY THOUGHT. FINALLY SOLD THE VEHICLE DUE TO CONTINUING PROBLEM THAT NO ONE COULD SOLVE. *TR”

KNOCK SENSOR BAD,EGR VALVE BAD...NUMEROUS THINGS WRONG WITH THE CAR AND LESLIE REED'S AUTO KNEW IT WAS A LEMON CAR. IT HAS A SALVAGED TITLE AND LESLIE REED'S AUTO NEVER GOT THE CAR REPAIRED BEFORE THEY SOLD THE CAR. *TR”
