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 PASSENGER VEHICLES HAVE LOWER PINION BEARINGS IN THE POWER RACK AND PINION ASSEMBLY IN WHICH THE RETAINER TABS WERE NOT CRIMPED PROPERLY. THESE RETAINERS COULD FAIL AND PERMIT THE BALL BEARINGS TO ESCAPE.

IF THIS OCCURS, THE PINION SHAFT CAN BE FORCED UPWARD DURING LEFT TURNS AND BACK DOWN AS THE STEERING WHEEL IS MOVED BACK AND TO THE RIGHT. IF THE PINION SHAFT MOVES FURTHER, THE DRIVER WILL NEED TO EXERT MORE EFFORT TO TURN THE STEERING WHEEL, SIMILAR TO A VEHICLE WITHOUT POWER ASSISTED STEERING. IF THE PINION SHAFT MOVES EVEN FURTHER, THE DRIVER WILL REQUIRE MUCH HIGHER EFFORT TO TURN LEFT AND MAY NOT BE ABLE TO TURN THE WHEEL AS MUCH AS INTENDED. WITH THE MAXIMUM PINION SHAFT MOVEMENT, WHICH REQUIRES INTERNAL GEAR COMPONENT DAMAGE, THE DRIVER CAN ENCOUNTER HIGH RESISTANCE TO TURNING LEFT, FOLLOWED BY UNINTENDED POWER ASSIST TO THE RIGHT. IN ANY OF THESE CONDITIONS, A CRASH COULD OCCUR.

DEALERS WILL INSTALL A NEW LOWER PINION BEARING UNLESS INSPECT OF THE EXISTING BEARING INDICATES THAT REPLACEMENT OF THE GEAR ASSEMBLY IS NECESSARY. OWNER NOTIFICATION BEGAN ON FEBRUARY 5, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080; CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR PONTIAC AT 1-800-620-7668.

A BACKFIRE DURING ENGINE STARTING CAN CAUSE BREAKAGE OF THE UPPER INTAKE MANIFOLD.

THIS CONDITION CAN CAUSE A NO-START CONDITION AND POSSIBLY AN ENGINE COMPARTMENT FIRE.

DEALERS WILL UPDATE THE POWERTRAIN CONTROL MODULE PROGRAMMING. UNTIL THE CAMPAIGN REPAIR IS MADE, THE VEHICLE HOOD SHOULD BE SHUT WHENEVER STARTING THE VEHICLE TO REDUCE THE CHANCE OF PERSONAL INJURY.

THE LEFT FRONT BRAKE LINE CAN CONTACT THE TRANSAXLE MOUNTING BRACKET OR ATTACHMENT BOLT.

THIS CONDITION CAN CAUSE THE BRAKE LINE TO WEAR THROUGH, RESULTING IN LOSS OF BRAKE FLUID AND EVENTUAL LOSS OF ONE-HALF OF THE VEHICLE'S BRAKE SYSTEM, INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.

DEALERS WILL INSPECT THE VEHICLE FOR PROPER BRAKE LINE CLEARANCE AND REPOSITION THOSE BRAKE LINES FOUND TO HAVE LESS THAN MINIMAL CLEARANCE. ADDITIONALLY, THOSE BRAKE LINES FOUND TO HAVE AN INDENTATION CAUSED BY THE CONTACT WILL BE REPLACED AND PROPERLY ROUTED.
