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.

IF THE SWITCH IS DAMAGED, A FIRE COULD OCCUR IN THE STEERING COLUMN, EVEN WITH THE ENGINE OFF AND THE KEY REMOVED.

DEALERS WILL INSTALL A RELAY KIT IN THESE VEHICLES TO PREVENT HIGH CURRENT FROM FLOWING THROUGH THE IGNITION SWITCH. OWNER NOTIFICATION BEGAN MARCH 27, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, PONTIAC AT 1-800-762-2737, BUICK AT 1-800-521-7300, OR OLDSMOBILE AT 1-800-442-6537.

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.

FUEL MAY LEAK, POSSIBLY RESULTING IN A FIRE.

DELPHI WILL NOTIFY OWNERS AND REPLACE THE UPR FREE OF CHARGE. THE RECALL BEGAN ON APRIL 23, 2007. OWNERS CAN CONTACT DELPHI AT 877-411-8770.

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.

A STALLED VEHICLE CAN INCREASE THE RISK OF A VEHICLE CRASH. A FUEL LEAK CAN RESULT IN A FIRE.

DELPHI WILL NOTIFY OWNERS AND REPLACE THE DEFECTIVE MRAS FREE OF CHARGE. THE RECALL BEGAN ON MARCH 20, 2007. OWNERS CAN CONTACT DELPHI AT 1-877-335-7443.

THE PROTECTIVE COVER FOR THE UNDERHOOD FUSE CENTER WAS OMITTED. WITHOUT THIS COVER, THE POSITIVE TERMINAL BOLT ON THE FUSE BLOCK IS EXPOSED AND CAN CONTACT THE INSULATED NEGATIVE BATTERY CABLE. IF THE INSULATION ON THE NEGATIVE CABLE BECOMES SUFFICIENTLY WORN, AN ELECTRICAL SHORT CIRCUIT CAN OCCUR BETWEEN THE POSITIVE TERMINAL AND NEGATIVE CABLE RESULTING IN EXTREMELY HIGH CURRENT FLOW.

THIS HIGH CURRENT FLOW CAN CAUSE ARCING AND RESULT IN AN UNDERHOOD FIRE.

DEALERS WILL INSPECT THESE VEHICLES FOR THE PRESENCE OF THE PROTECTIVE COVER AND, IF NECESSARY, INSTALL A PROTECTIVE COVER TO THE UNDERHOOD FUSE CENTER.

DURING ASSEMBLY OF THE LEFT REAR QUARTER PANEL, SOME WELDS WERE MISSED. THIS DOES NOT COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 301, "FUEL SYSTEM INTEGRITY."

IN THE EVENT OF A REAR END COLLISION, THE VEHICLE SHEET METAL STRUCTURE WILL NOT PERFORM AS DESIGNED CAUSING UNEXPECTED DAMAGE TO THE FUEL TANK OR FUEL LINES, RESULTING IN FUEL LEAKAGE. IF THIS IS A FUEL LEAK AND AN IGNITION SOURCE, A FIRE COULD OCCUR.

DEALERS WILL INSPECT FOR THE MISSING WELDS AND, IF NECESSARY, PLACE THREE WHELDS BETWEEN THE INVOLVED PANELS APPLYING PRIMER, SEALER AND ANTI-CORROSION MATERIALS.
