2001 Ford F-550 Sd recalls and problems

IN A DECEMBER 3, 2007 LETTER, FORD ADVISED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL TO REPLACE THE CAM POSITION SENSOR (CPS) IN APPROXIMATELY 1.2 MILLION SUBJECT VEHICLES TO ADDRESS REPORTS OF ENGINE STALLING.A NEW DESIGN CPS WITH IMPROVED PERFORMANCE AND DURABILITY WILL BE INSTALLED AS A REMEDY.OWNER NOTIFICATIONS WILL BEGIN IN DECEMBER 2007. THE SUBJECT VEHICLES ARE DURABLE, FULL-SIZED, MEDIUM DUTY TRUCKS COMMONLY USED FOR COMMERCIAL PURPOSES, RESCUE/EMERGENCY RESPONSE, AND COMMERCIAL OR RECREATIONAL TOWING.CPS FAILURE IS COMPARABLE TO UNEXPECTEDLY TURNING THE KEY OFF SINCE THE SIGNAL IT PRODUCES IS VITAL TO THE ELECTRONIC ENGINE CONTROL SYSTEM.CPS SIGNAL LOSS TERMINATES FUEL INJECTION RESULTING IN AN ENGINE STALL.ONCE STALLED, THE ENGINE MAY RESTART RIGHT AWAY, OR MAY RESTART AFTER A DELAY (TYPICALLY 5 TO 10 MINUTES), OR MAY NOT RESTART AT ALL.IN ADDITION TO EXPOSING THE DRIVER AND OTHER MOTORISTS TO CRASH RISK DUE TO LOSS OF MOTIVE POWER OR VEHICLE DISABLEMENT, ENGINE STALLING ALSO EFFECTS THE POWER ASSISTED STEERING AND BRAKING. THROUGH CONSUMER INTERVIEWS, ODI DETERMINED THAT CPS FAILURES OCCURRED WITHOUT ANY FORM OF WARNING, AT ANY VEHICLE SPEED (50% AT HIGHWAY SPEEDS), AND UNDER ANY DRIVING CONDITION, SUCH AS ACCELERATING.CONSUMERS REPORTED THAT ABOUT A THIRD OF THE VEHICLES FAILED TO RESTART, WITH ANOTHER THIRD REPORTING DELAYED RESTARTING.HALF THE VEHICLES THAT DID RESTART EXPERIENCED ANOTHER STALL ON THE SAME OR A SUBSEQUENT DRIVE CYCLE (BEFORE CPS REPLACEMENT) R…

EA05-005 IS CLOSED WITH FORD?S ACTIONS IN RECALLS 05V-017, 05V-388, AND 06V-286, RECALLING APPROXIMATELY 6.7 MILLION VEHICLES EQUIPPED WITH TEXAS INSTRUMENTS SPEED CONTROL DEACTIVATION SWITCHES (SCDS).THE BRAKE SYSTEMS IN THESE RECALLED VEHICLES GENERATE A VACUUM THAT CAN POTENTIALLY CAUSE THE SCDS TO FAIL AND, IN CERTAIN SWITCH INSTALLATION ORIENTATIONS, CATCH FIRE.FORD IS ALSO INCLUDING THE ENTIRE POPULATION OF 1998 EXPLORERS.FORD HAS INFORMED ODI THAT TESTING TO DETERMINE THE CAUSE OF FAILURES IN THE 1998 EXPLORERS WILL CONTINUE AFTER THIS INVESTIGATION IS CLOSED.ODI BELIEVES THAT THE VEHICLES EXHIBITING THE FACTORS CAUSING SCDS FAILURE DESCRIBED IN THIS REPORT CORRELATE WELL WITH THE OBSERVED FAILURE RATES ON THESE VEHICLES BY MODEL AND MODEL YEAR.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST IN THE NON-RECALLED VEHICLES MANUFACTURED WITH SCDS THAT ARE NOT INCLUDED IN FORD?S RECALLS.ODI WILL CONTINUE TO MONITOR THE NON-RECALLED POPULATION FOR INCIDENCE OF ENGINE COMPARTMENT FIRES.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE ATTACHED CLOSING REPORT FOR DETAILS.

DURING THE INITIAL RECALL CAMPAIGN IN 2001, THE SUBJECT VEHICLES WERE INSPECTED BY FORD DEALERSHIPS USING A TEST TOOL THAT WOULD DETECT A DEFECTIVE FRONT SEAT OUTBOARD SEAT BELT BUCKLE ASSEMBLY.APPROXIMATELY ONE MILLION VEHICLES PASSED THE INSPECTION TEST FOR ONE OR BOTH FRONT BUCKLES.SUBSEQUENT TO THE RECALL SERVICE ACTION, ODI RECEIVED 15 CONSUMER REPORTS ALLEGING THAT A PASSED INSPECTION BUCKLE SUBSEQUENTLY FAILED TO LATCH OR INADVERTENTLY UNLATCHED DURING USE.IN ADDITION, FORD HAS IDENTIFIED 543 OWNER AND FIELD REPORTS ALLEGING BUCKLE FAILURE SUBSEQUENT TO PASSING THE INSPECTION TEST.FORD TESTED AND EXAMINED OVER 100 WARRANTY-RETURNED BUCKLES AND FOUND THAT 44% OF THE BUCKLES HAD NO PROBLEM OR A CONDITION NOT RELATED TO THE RECALL INSPECTION (NON-LATCH RELATED BUCKLE DAMAGE OR FOREIGN CONTAMINATION).WARRANTY CLAIMS WERE HIGHEST DURING THE 18-MONTH PERIOD AFTER THE START OF THE RECALL (JULY 2001) AND HAVE BEEN DECLINING DURING THE PAST 24 MONTHS.OVER THE PAST 12 MONTHS, FORD HAS RECEIVED APPROXIMATELY 12 WARRANTY CLAIMS PER MONTH OUT OF A VEHICLE POPULATION OF ABOUT ONE MILLION.COMPLAINTS COUNTS ARE ALSO DECREASING.DURING THE PAST SEVEN MONTHS, ODI HAS RECEIVED ONLY TWO COMPLAINTS. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGEN…

UNDER RECALL CAMPAIGN (01V227), FORD RECALLED APPROXIMATELY 1.3 MILLION VEHICLES TO INSPECT AND IF NECESSARY REPLACE THE FRONT DRIVER AND/OR PASSENGER SEAT BELT BUCKLE.APPROXIMATELY 1.1 MILLION OWNERS RESPONDED BY TAKING THEIR VEHICLES TO A DEALER FOR INSPECTION OF THE BUCKLE USING A SPECIALIZED BUCKLE TEST TOOL.FORD REPORTED THAT 829,927 VEHICLES HAD BOTH BUCKLES PASS THE TOOL TEST AND ANOTHER 167,336 VEHICLES HAD ONE BUCKLE PASS.ODI AND FORD RECEIVED COMPLAINTS ALLEGING SEAT BELT BUCKLE FAILURE SHORTLY AFTER PASSING THE ORIGINAL RECALL INSPECTION SERVICE.COMPLAINANTS ALLEGED THAT THE BUCKLE FAILED BY EITHER NOT LATCHING OR FALSE-LATCHING (PARTIAL ENGAGEMENT OF THE LATCH TO THE LATCH PLATE).A FALSE-LATCHED BUCKLE MAY RELEASE WITH MINOR MOVEMENT OR IMPACT AGAINST THE BUCKLE HOUSING INCLUDING INADVERTENT RELEASE WHILE THE VEHICLE IS IN MOTION.ODI IS UPGRADING THIS RECALL QUERY TO AN ENGINEERING ANALYSIS (EA05-004) TO FURTHER ANALYZE THE FIELD PERFORMANCE OF THOSE VEHICLES THAT FORD DEALERS PASSED (ONE OR BOTH BUCKLES) USING FORD'S INSPECTION TEST (997,263 VEHICLES).

FAILURE COUNTS FROM ODI?S ANALYSIS ARE STATED ABOVE; SEE THE ADDITIONAL PROBLEM EXPERIENCE DISCUSSION IN THE SUMMARY REPORT.FORD DATA CONTAINED DUPLICATIVE REPORTS FOR 4 ODI COMPLAINTS AND 1 CRASH.THREE CRASHES WERE ALLEGEDLY DUE TO INTERMITTENT OPERATION OF THE ELECTRONIC THROTTLE CONTROL (ETC) PEDAL, ONE CRASH OCCURRED WHEN AN ETC DISABLED VEHICLE WAS STRUCK BY ANOTHER MOTORIST, ONE REPORT CONTAINED NO DETAIL.THE INJURIES WERE MINOR.AN ISSUE INVOLVING FIXED ETC PEDALS WAS INVESTIGATED ALSO, HOWEVER FAILURE REPORTS AND POPULATIONS ARE NOT SHOWN ABOVE; SEE SUMMARY REPORT FOR DETAIL.ALTHOUGH FORD HAS USED ETC BASED THROTTLE CONTROL SYSTEMS FOR MANY YEARS, THE PAP FEATURE WAS NEW FOR MY 2002.THE SUBJECT ETC SENSOR PRODUCES TWO OUTPUT SIGNALS WHICH THE ENGINE MANAGEMENT SYSTEM (EMS) UTILIZES TO:1) DETERMINE FUELING REQUIREMENTS; AND 2) PERFORM SENSOR DIAGNOSTICS.ONE SIGNAL IS LINEARLY PROPORTIONAL TO THROTTLE PEDAL POSITION; THE SECOND IS A DIGITAL SIGNAL.BY DESIGN, THE DETECTION OF A SENSOR FAULT RESULTS IN THE ENGINE RETURNING TO (OR REMAINING AT) THE IDLE STATE.FORD IDENTIFIED A DEFECT IN THE PAP ETC SENSOR WHICH PREMATURELY AFFECTED AN OUTPUT SIGNAL; THE MIGRATION OF INTERNAL SENSOR LUBRICANT CAUSED A LOSS OF PROPORTIONAL SIGNAL.THE FAILURE MECHANISM IS PROGRESSIVE AND AS THE SENSOR DETERIORATES, THE EMS WILL DETECT A FAULT, STORE A FAULT CODE, ILLUMINATE A WARNING LAMP, AND THE ENGINE MAY REMAIN AT/RETURN TO IDLE.IN THE EARLY STAGES, NORMAL OPERATION CAN BE REGAINED BY PEDA…

THIS INVESTIGATION WAS OPENED ON CERTAIN FORD PICKUP TRUCKS AND VANS TO EVALUATE THE EFFECTS OF A VALVE STEM EJECTION (WITH RAPID AIR LOSS) AND A SLOW LEAKING VALVE STEM ON VEHICLE HANDING.DURING THE INVESTIGATION, ODI EVALUATED OVER 1,100 COMPLAINTS AND WARRANTY CLAIMS, CONDUCTED VEHICLE DYNAMIC TESTING ON A SUBJECT VEHICLE WITH THE FAILURE MODE REPLICATED, INTERVIEWED OWNERS, AND EXAMINED COMPLAINT VEHICLES IN THE FIELD.THE RESULTS OF THE TEST PROGRAM INDICATES THE EFFECT OF A VALVE STEM EJECTION ON THESE VEHICLES IS EASILY CONTROLLED. FURTHER, WITH A POPULATION OF ALMOST 900,000 VEHICLES, HAVING TWO TO FOUR YEARS OF EXPOSURE, ODI IS AWARE OF ONLY 3 MINOR CRASHES AND IS UNAWARE OF ANY INJURIES.THE SMALL NUMBER OF CRASHES RELATIVE TO THE LARGE POPULATION OF VEHICLES IS CONSISTENT WITH THE TESTING WHICH WAS PERFORMED. THEREFORE, THIS INVESTIGATION IS CLOSED.SEE THE ATTACHED REPORT FOR FULL TECHNICAL DETAILS.

THIS EA WAS OPENED BASED ON A RESPONSE RECEIVED FROM FORD MOTOR COMPANY TO AN INFORMATION REQUEST (IR) SUBMITTED DURING SQ00-018.FORD STATED IN AN INTERNAL SERVICE MESSAGE THAT IT HAD CHANGED THE STEERING GEAR SECTOR SHAFTS AND PITMAN ARMS INSTALLED 1999 MODEL YEAR F-SERIES SUPER DUTY VEHICLES ON MARCH 22, 1999.FORD STATED THAT THESE DESIGN CHANGES WERE IMPLEMENTED TO MAKE IMPROVEMENTS IN VEHICLE STEERING AND HANDLING, AND THAT VIRTUALLY ALL OF THE REPORTED FRACTURED SECTOR SHAFTS WERE THE RESULT OF EXTRAORDINARY, POSSIBLY MULTIPLE, IMPACTS.AN ENGINEERING ANALYSIS CLOSING REPORT IS ATTACHED.
