1993 FORD EXPEDITION

SOME VEHICLES MAY EXPERIENCE AXLE WIND UP AND / OR CLUNKING, POPPING, RATCHETING TYPE NOISES WHEN MAKING CORNERING MANEUVERS ON VEHICLES EQUIPPED WITH A FOUR WHEEL DRIVE HI OR LOW RANGE MODE. *TT

The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of transmissions unexpectedly downshifting to a lower gear without input from the driver on model year (MY) 2011-2013 Ford F-150, Expedition and Navigator vehicles. ODI has received 455 unique reports rel... ated to the alleged problem that were not covered under a previous recall for this issue (16V-248).Expedition and Navigator complaint rates are lower than F-150 complaints. Of those 455 reports, 34.7% claimed that the rear wheels locked up when the transmission downshifted. There were 4 accident claims with no injuries. There are many instances where drivers report leaving their lane or the road because of this issue.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 783 unique reports related to the alleged problem. There were 6 accident claims with 3 injuries. Ford also submitted 1206 warranty claims related to transmission downshifting failures. The failure can occur at any time, but typically at higher speed, and include symptoms such as sudden transmission downshifting, loss of speedometer, erratic shifting of transmission, and transmission stuck in one gear. The failures typically occur without warning and may result in the rear wheels momentarily locking up. The driver often had to fully stop the vehicle and restart it to get the vehicle to shift properly.On February 2nd, 2019 Ford notified ODI that it would conduct a safety recall (19V-075) to remedy transmission downshifting failures on all 2011-2013 F-150 vehicles. Ford will also offer extended warranties to 2011-2013 Expedition and Navigator vehicles with the same issue. Per Ford, some vehicles may experience an intermittent loss of Transmission Output Speed Sensor (OSS) signal to the Powertrain Control Module (PCM), potentially resulting in a temporary unintended downshift into first gear. Ford will reprogram the PCM with software that will prevent an unintended downshift into first gear and illuminate the Malfunction Indicator Light in the event of an intermittent OSS signal loss.The recall action initiated by the manufacturer appears to address the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers found in the attached list.Read more

FORD SPECIAL SERVICE VEHICLE (SSV) EXPEDITIONS USE A STEEL FULL FACE WHEEL DESIGN SIMILAR TO THAT INVESTIGATED IN PE03009, RQ04007, EA04034 (CROWN VICTORIA POLICE INTERCEPTOR) AND PE03026 (GM PICKUPS AND SUVS).A TOTAL OF 8,251 SSVS (2.2% OF TOTAL PRODUCTION) WERE PRODUCED WITHIN MODEL YEARS 2004-200... 6 AND SOLD PRIMARILY FOR USE BY STATE, FEDERAL, AND MUNICIPAL LAW ENFORCEMENT (LE) AGENCIES.FORD STIPULATES THAT THE SUBJECT VEHICLES ARE NOT SUITABLE FOR HIGH SPEED OR PURSUIT OPERATIONS AND ALSO IDENTIFIED A 2004 NATIONAL INSTITUTE FOR JUSTICE VEHICLE EVALUATION REPORT WHICH ALSO ACKNOWLEDGES THIS LIMITATION. THE FULL FACE WHEEL IS FABRICATED FROM TWO PIECES: A STAMPED OUTER WHEEL DISC AND A FORMED RIM.THE TWO PIECES, WHICH TOGETHER COMPRISE THE OUTER BEAD SEAT, ARE JOINED TOGETHER WITH A CIRCUMFERENTIAL WELD.A CYCLIC BENDING MOMENT OCCURS IN THE OUTER BEAD SEAT AREA AS THE WHEEL ROTATES, RESULTING IN FATIGUE STRESSES IN THE WELD'S HEAT AFFECTED ZONE THAT CAN LEAD TO FRACTURING (CRACKING) OF THE RIM MATERIAL.BECAUSE THE FAILURE OCCURS UNDER THE OUTBOARD TIRE BEAD, AIR LEAKAGE MAY NOT READILY OCCUR WHEN THE RIM CRACKS, DEPENDENT ON HOW WELL THE BEAD SEALS ON THE RIM.IF MULTIPLE CRACKS GROW UNDETECTED AND SUDDENLY JOIN INTO A SINGLE LARGE CRACK, THE WHEEL'S STRUCTURE CAN BECOME COMPROMISED LEADING TO RAPID AIR LOSS.A RAPID AIR LOSS, ESPECIALLY AT HIGHER SPEED, MAY LEAD TO A CRASH. FORD RESPONDED TO ODI'S JANUARY 5, 2009 INFORMATION REQUEST (IR) ON FEBRUARY 24.FORD'S RESPONSE ACKNOWLEDGES A NUMBER OF WHEEL FRACTURES ON THE SSVS.HOWEVER, BASED ON ITS ASSESSMENT OF THE PERTINENT FACTORS, IT CONCLUDES THAT THE CONDITION DOES NOT REPRESENT AN UNREASONABLE RISK TO SAFETY.THE LACK OF REPORTS OF RAPID AIR LOSS, NO ALLEGED CRASHES, AND THEIR ASSESSMENT THAT A CRACKED WHEEL CAN BE DETECTED THROUGH SLOW, REPEATED AIR LOSS OR VIBRATION, WERE THE BASES FOR FORD'S CONCLUSION.FORD DISCUSSES THE RESULTS OF A STUDY IT PERFORMED ON WHEELS RETURNED FROM LE FIELD USE, DESIGN REVISIONS IT MADE TO THE SUBJECT WHEEL, AND THE OUTCOME OF DURABILITY TESTING IT CONDUCTED ON THE OLD AND NEW WHEEL DESIGNS. THE COUNTS SHOWN ABOVE INCLUDE A DUPLICATE ODI AND FORD REPORT; THE FORD COUNTS ARE UNIQUE VEHICLES ALLEGING WHEEL FRACTURE(S).SOME WARRANTY CLAIMS INVOLVED MORE THAN ONE WHEEL REPLACEMENT.ALTHOUGH THE SUBJECT VEHICLES HAVE BEEN IN SERVICE FOR A LONGER PERIOD OF TIME THAN VEHICLES INVESTIGATED IN THE PREVIOUS INVESTIGATIONS OF TWO-PIECE WHEEL FRACTURE, ODI DID NOT IDENTIFY ANY ALLEGATIONS OF CRASHES, RAPID AIR LOSS EVENTS DUE TO WHEEL FRACTURES OR ALLEGATIONS OF EFFECTS ON VEHICLE CONTROL OR STABILITY, AS WERE THE CASES IN PAST INVESTIGATIONS WHERE SAFETY RECALLS WERE CONDUCTED TO REPLACE AFFECTED WHEELS.THE AGENCY AGREES THAT THE SSV IS NOT SUITABLE FOR PURSUIT OR HIGH SPEED USAGE, REDUCING THE POTENTIAL FOR CRASHES OR LOSS OF CONTROL INCIDENTS TO BE CAUSED BY THE ALLEGED DEFECT. FORD IMPLEMENTED A 'SHOT PEENING' PROCESS IN JUNE 2006 WHICH REDUCED THE WHEEL'S SURFACE STRESS AND SIGNIFICANTLY IMPROVED ITS DURABILITY, AND ODI IS UNAWARE OF ANY FAILURES OF SHOT PEENED WHEELS (SERVICE PART NUMBER 7L1Z-1015-B).FORD'S TESTING SHOWED A SLIGHTLY REDUCED DURABILITY FOR THE NON-SHOT PEENED WHEELS WHEN 'LT' INSTEAD OF FORD APPROVED 'P' METRIC TYPE TIRES ARE USED. 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 AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY FURTHER CRead more

CONSUMERS ALLEGED THAT WHEN IT RAINED OR SNOWED, WATER LEAKED INTO THE VEHICLE AROUND THE WINDSHIELD.MOISTURE FLOWING THROUGH THE SEAL THAT SURROUNDS THE FRONT WINDSHIELD FOLLOWS A PATH THROUGH THE SEAL INTO THE GENERIC ELECTRONIC MODULE (GEM) AND FUSE BOX, AND MAY CAUSE THE ELECTRICAL COMPONENTS IN... THE VEHICLE TO MALFUNCTION.OVERALL, THE NUMBER OF REPORTS ALLEGING WIPER FAILURES AND LIGHTING FAILURES IS RELATIVELY SMALL.IN REVIEWING A LARGE SAMPLE OF THE 1503 COMPLAINTS FOR WINDSHIELD LEAKS, ODI'S ANALYSIS REVEALS THAT 0.04% OF THE TOTAL VEHICLE POPULATION REPORTED IMPROPER WINDSHIELD WIPER OPERATION AND 0.01% OF THE TOTAL VEHICLE POPULATIONREPORTED LIGHTING FAILURES.THE WARRANTY CLAIMS REVEAL THAT APPROXIMATELY 0.10% OF THE POPULATION HAS BEEN SERVICED FOR WIPER MALFUNCTIONS AND 0.08% FOR LIGHTING MALFUNCTIONS AS A RESULT OF WINDSHIELD LEAKING. ODI'S ANALYSIS OF THE FIELD PERFORMANCE STATISTICS AND AVAILABLE TECHNICAL INFORMATION HAS NOT ESTABLISHED THAT A DEFECT TREND EXISTS IN THE MALFUNCTION, FAILURE OR INTERMITTENT OPERATION OF THE FRONT WINDSHIELD WIPERS OR HEADLIGHTS.SEE THE ATTACHED SUMMARY REPORT.Read more

ODI HAS RECEIVED 39 REPORTS ALLEGING THAT WATER LEAKS AROUND THE WINDSHIELD CAUSING ELECTRICAL FAILURES, INCLUDING BUT NOT LIMITED TO THE WINDSHIELD WIPERS AND THE HEADLAMPS.FORD REPORTS THAT WATER ENTERING THE VEHICLE CAN WET THE POWER DISTRIBUTION BOX (PDB) AND THE GENERIC ELECTRONIC MODULE (GEM).... THESE COMPONENTS CONTROL VARIOUS ELECTRICAL SYSTEMS IN THE VEHICLE.THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS, EA05015, TO ALLOW FURTHER INVESTIGATION OF THE ISSUE AND TO ASSESS THE NATURE OF THE POTENTIAL SAFETY CONSEQUENCE.Read more

IN ITS LETTER DATED JANUARY 27, 2005 TO ODI, FORD INDICATED THAT IT WOULD CONDUCT A SAFETY RECALL (NHTSA RECALL # 05V-017) TO REMEDY AN OVERHEATING SPEED CONTROL DEACTIVATION SWITCH IN APPROXIMATELY 738,490 SUBJECT VEHICLES.THE VEHICLES AFFECTED BY THE RECALL ARE CERTAIN 2000 MODEL YEAR (MY) FORD F1... 50, FORD EXPEDITION AND LINCOLN NAVIGATOR EQUIPPED WITH SPEED CONTROL AND CERTAIN 2001 MODEL YEAR F150 SUPERCREW VEHICLES BUILT THROUGH AUGUST 7, 2000.SINCE OPENING PE04-078, ODI HAS IDENTIFIED OTHER REPORTS OF KEY OFF ENGINE COMPARTMENT FIRES IN FORD VEHICLES WITH SIMILAR SPEED CONTROL DEACTIVATION SWITCHES THAT WERE NOT THE SUBJECT OF THIS PRELIMINARY EVALUATION OR FORD'S RECALL 05V-017.FORD'S RESPONSE TO THE ODI INFORMATION REQUEST LETTER DATED DECEMBER 3, 2004, PROVIDED AN ADDITIONAL 107 ALLEGATIONS OF KEY OFF ENGINE COMPARTMENT FIRES THAT WERE ALSO IN VEHICLES NOT SUBJECT TO THIS INVESTIGATION OR INCLUDED IN THE FORD RECALL 05V-017.AN ENGINEERING ANALYSIS (EA) IS WARRANTED TO DETERMINE IF A SAFETY DEFECT TREND EXISTS RELATING TO KEY OFF ENGINE COMPARTMENT FIRES IN VEHICLES OUTSIDE THE SCOPE OF THIS PRELIMINARY EVALUATION.ODI WILL EXPAND THE SCOPE OF IT'S INVESTIGATION AT THE EA PHASE TO INCLUDE THE 1995 THROUGH 2002 MODEL YEARS OF THE FORD F150, FORD EXPEDITION AND LINCOLN NAVIGATOR VEHICLES.Read more

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 BUC... KLE 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).Read more
