FORD IS RECALLING CERTAIN MODEL YEAR 2004-2006 F-150 PICK UP TRUCKS AS WELL AS CERTAIN MODEL YEAR 2006 LINCOLN MARK LT VEHICLES. IF THE CLOCKSPRING JUMPER WIRE COMES IN CONTACT WITH THE DRIVER SIDE FRONTAL AIR BAG LOWER HORN PLATE, THE WIRE INSULATION MAY BECOME CHAFED, CREATING A POTENTIAL FOR A SHORT CIRCUIT. IF THIS OCCURS THE AIR BAG WARNING LAMP MAY ILLUMINATE INDICATING THAT SERVICE IS REQUIRED.
FORD IS RECALLING 605,684 MY 2005-2006 F-150 AND LINCOLN MARK LT VEHICLES EQUIPPED WITH 5.4L 3-VALVE ENGINES. THE BRAKE BOOSTER VACUUM SUPPLY HOSE ATTACHED TO THE INTAKE MANIFOLD FITTING MAY SWELL OVER TIME AND LOSE RETENTION FORCE. THIS CONDITION COULD ALLOW THE HOSE TO BECOME DETACHED FROM THE FITTING DURING AN INTAKE MANIFOLD BACKFIRE. SHOULD THE HOSE DETACH FROM THE INTAKE MANIFOLD, SEVERAL BRAKE APPLICATIONS WITH POWER ASSIST WILL BE AVAILABLE BEFORE THE VACUUM RESERVE IS DEPLETED.
CERTAIN AFTERMARKET FUEL FILTERS SOLD UNDER THE PUROLATOR BRAND NAME, P/N F65277, SHIPPED FROM JANUARY 16 THROUGH JUNE 2, 2006, FOR USE ON THE ABOVE LISTED PASSENGER VEHICLES. DUE TO INCORRECT DESIGN, THE QUICK CONNECTORS MAY NOT FULLY SEAT WITH THE TUBE INTERFACE, EVEN THOUGH THE PERSON MAKING THE CONNECTION MAY BELIEVE THAT THE QUICK CONNECTOR IS FULLY ATTACHED.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.

THE VEHICLE SINCE STALLED TWICE AFTER REACHING 100K+ MILES AND DRAINING TWO BATTERY, SHUTTING DOWN THE ENGINE WITHOUT WARNING AT A LOW SPEED AND WHILE TRYING TO TURN. THIS RENDERED THE BRAKES AND POWER STEERING USELESS - WE JUST BARELY AVOIDED FRONTAL COLLISION WITH STREET SIGNS AND A BRIDGE AS WELL AS ALMOST BEING REAR-ENDED BY DRIVER BEHIND US. FORTUNATELY, BOTH WERE AT LOW SPEED AND ON LOCAL RURAL ROADS. ALSO, THE VEHICLE HAS BEGAN HESITATING WHEN ACCELERATING MOSTLY @ 45-50 MPH. THE DEALERSHIP COULD NOT RE-CREATE ISSUES AFTER FIRST INCIDENT AND THE DIAGNOSTICS DID NOT SHOW ANY ERROR CODES. FORD ISSUED TSB'S IN 2008 DESCRIBING " THE ENGINE PROBLEMS ARE THE RESULT OF DEFECTS IN THE FOLLOWING VEHICLE SYSTEMS AND COMPONENTS: ...POWERTRAIN CONTROL MODULE (PCM), ...TRANSMISSION CONTROL MODULE (TCM, ...ELECTRONIC THROTTLE CONTROL (ETC) AND/OR THE THROTTLE BODY ASSEMBLY" WHICH CAN LEAD TO THE FOLLOWING PERFORMANCE AND SAFETY ISSUES " ACCELERATION HESITATION, LOSS OF REVOLUTIONS PER MINUTE, STALLING, LOSS OF POWER (INCL.
