2001 Ford F Super Duty 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…

THE CAM POSITION SENSOR (CPS) PROVIDES A CRITICAL SIGNAL TO THE SUBJECT VEHICLE (SV) ENGINE MANAGEMENT SYSTEM, THE LOSS OF WHICH RESULTS IN AN ENGINE STALL.DURING PE06-011, FORD STATED IN THEIR RESPONSE TO ODI THAT IT IS CONTINUING TO INVESTIGATE ALLEGATIONS OF CPS RELATED ENGINE STALL AND FURTHER ADVISED THAT AN UPDATE WILL BE PROVIDED UPON COMPLETION OF THE INVESTIGATION.FORD DATA SHOWS THAT 20% OF THE 716,000 SVS ARE EQUIPPED WITH MANUAL TRANSMISSIONS WHICH ARE CAPABLE OF BACK-DRIVING THE ENGINE WHEN A STALL OCCURS; POWER ASSISTED STEERING AND BRAKING ARE NOT LOST DURING ENGINE BACK-DRIVE.FORD DATA ALSO INDICATES THAT BACK-DRIVE OCCURS IN AUTOMATIC TRANSMISSION VEHICLES ABOVE CERTAIN ROAD SPEEDS.THE MANUFACTURER REPORTS NOTED REFERENCE 755 UNIQUE VEHICLES; 2 ARE DUPLICATIVE OF ODI REPORTS.IN ITS REVIEW OF CUSTOMER AND FIELD REPORTS, FORD IDENTIFIED SOME 800 REPORTS ALLEGING ONE OR MORE ENGINE STALLS POTENTIALLY RELATED TO A CPS FAILURE IN THESE 755 VEHICLES (FORD?S ?A? CATEGORY REPORTS).ODI HAS NOT COMPLETED ITS REVIEW OF THESE OR OTHER FORD REPORTS, NOR HAS IT CONFIRMED THIS COUNT.ALL BUT ONE OF THE 9 CRASH ALLEGATIONS APPEAR TO BE MINOR IN NATURE ALTHOUGH ODI IS STILL INVESTIGATING THESE CRASH/INJURY ALLEGATIONS AND WHETHER OR NOT THEY INVOLVE A CPS FAILURE.BASED ON EARLY ASSESSMENT OF THE APPROXIMATELY 166,000 SUBJECT VEHICLE WARRANTY CLAIMS FORD PAID, THERE APPEARS TO BE VARIABILITY IN CLAIM RATES BETWEEN CERTAIN SV PRODUCTION PERIODS; AN EXPLANATION FOR THIS HAS NOT B…

ON SEPTEMBER 6, 2005, ODI RECEIVED A PETITION REQUESTING THAT THE AGENCY INVESTIGATE ALLEGATIONS OF ENGINE SPARK PLUG EJECTION IN CERTAIN MODEL YEAR 1997 THROUGH 2004 FORD VEHICLES WITH TRITON V-8 AND V-10 ENGINES.ODI RECEIVED A TOTAL OF 474 NON-DUPLICATIVE COMPLAINTS ON THE SUBJECT VEHICLES WHERE THE COMPLAINANT, OR THE DEALER REPAIRING THE VEHICLE, REPORTED THAT A SPARK PLUG DETACHED FROM THE CYLINDER AND/OR EJECTED FROM THE ENGINE.AS OF DECEMBER 8, 2005, ODI IS NOT AWARE OF ANY ALLEGATIONS WHERE THE ALLEGED DEFECT RESULTED IN A LOSS OF VEHICLE CONTROL, A CRASH, AN INJURY, OR A FATALITY IN ANY OF THE 10,319,810 SUBJECT VEHICLES.IN ADDITION, ODI IS AWARE OF ONLY TWO INCIDENTS WHERE THE VEHICLE STALLED WITHOUT RESTART.INFORMATION CONTAINED IN THE ODI CONSUMER COMPLAINTS AND OBTAINED FROM 72 TELEPHONE INTERVIEWS WITH COMPLAINANTS SHOWED THE FOLLOWING:(1) 99% OF THE COMPLAINTS WERE ON MY 1997 TO 2002 SUBJECT VEHICLES.(2) MOST THE COMPLAINANTS REPORTED HEARING A LOUD POP WHILE DRIVING OR UPON STARTING UP THE VEHICLE FOLLOWED BY A LOUD, REPETITIVE CLICKING OR POPPING SOUND.(3) MANY OF THE COMPLAINANTS REPORTED THAT THE POPPING SOUND WAS ACCOMPANIED BY SOME LOSS OF VEHICLE POWER; HOWEVER, IN 99% OF THE INCIDENTS REPORTED, THE VEHICLE DID NOT STALL.IN THE VERY FEW INCIDENTS WHERE THE VEHICLE DID STALL, MOST VEHICLES COULD BE RESTARTED.(4) ONLY A SMALL PERCENTAGE OF THE COMPLAINANTS CITED THAT THEY SMELLED GAS OR A SLIGHT BURNING SMELL WHEN THE INCIDENT OCCURRED.(5) IN ALL BUT A VER…

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…
