  Low-pressure fuel pump failure
  FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

  On July 29, 2024, the Office of Defects Investigation (ODI) opened PE24019 to investigate complaints of low-pressure fuel pump failures in MY 2021 Ford Bronco vehicles. Some consumers reported that the failure occurred without warning while driving, resulting in a complete loss of motive power with no ability to restart the engine. Ford determined that several other vehicle models contain low-pressure fuel pumps substantially similar to the 2021 Ford Bronco, including the 2022-2023 Ford Bronco, 2018-2023 Ford F-150, 2022-2023 Ford Expedition, 2019-2023 Lincoln Navigator, 2020-2023 Ford F-250-F-550, 2024 Ford Super Duty Chassis Cab, 2024-2025 Ford Ranger, 2020-2023 Ford Explorer, 2020-2023 Lincoln Aviator, and 2021-2025 Ford Mustang. ODI's investigation found that the affected vehicles may lose fuel pressure and flow from the fuel delivery module (consisting of a low-pressure fuel pump, jet pump, reservoir, and other parts) due to a low-pressure pump failure. This can cause the engine to stall while driving. The root cause is reduced internal clearance in the fuel pump, increasing friction and sensitivity to vapor lock. Fuel blockage from contamination inside the jet pump also contributed to the failure. Ford stated that the contamination source was unknown. On July 7, 2025, Ford filed recall 25V-455 for certain 2021-2023 Ford F-550 SD/F-450 SD/F-350 SD/F-250 SD, 2021-2022 Lincoln Navigator, 2021-2022 Ford Mustang, 2021-2022 Ford F-150, 2021-2023 Ford Explorer, 2022 Ford Expedition, and 2021-2023 Ford Bronco vehicles produced between July 1, 2021, and July 30, 2022. The recall also included certain 2021-2023 Lincoln Aviator produced between July 1, 2021, and December 21, 2022. Ford explained in its recall filingthat the production dates used for the recall were based on changes in the manufacturing process. Specifically, Ford determined that in June 2021, the supplier modified the jet pump manufacturing process, producing fuel pump chambers with a lower-than-specified internal clearance. In July 2022, the supplier implemented corrective actions to the manufacturing process by adding two additional vacuum pumps to reduce contamination during the production of the jet pump. ODI has identified approximately 1,000 reports involving vehicles covered in this investigation but excluded from recall 25V-455. However, even with such reports, these vehicles experienced comparatively lower failure rates than the vehicles that are subject to Recall 25V-455. Ford has explained that these vehicles were excluded from the recall population because they did not experience the manufacturing changes that prompted the recall. Specifically, according to Ford, vehicles built before July 1, 2021 (the recall production start date), were not affected by the supplier’s change to the jet pump manufacturing process. Even after closing this investigation, ODI will continue to monitor complaints for vehicles excluded from recall 25V-455 to consider whether they exhibit the same risks as the vehicles encompassed by the recall. The recall remedy is currently under development. In view of Ford’s recall action, ODI is closing this Preliminary Evaluation, but will continue to monitor the issue as a remedy is developed and implemented. ODI will take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

  Sogefi Secondary Diesel Fuel Filter Leak
  FUEL SYSTEM, DIESEL

  The Office of Defect Investigations (ODI) has received 27 complaints alleging diesel fuel leaks due to a fracture in the secondary fuel filter housing in model year (MY) 2015-2021 Ford Motor Company (Ford) F-250, 350, 450, and 550 Super Duty vehicles equipped with 6.7L diesel engines. Of these complaints, 12 describe an engine compartment fire. The proximity of the secondary fuel filter to high heat sources creates a potential for autoignition thermal events and fires. ODI has contacted the vehicle manufacturer, Ford, and the filter manufacturer, Allevard Sogefi USA (Sogefi), and learned that the low-pressure fuel system is capable of a maximum operating pressure of 8.5 Bar, while the secondary fuel filter is only tested to seven (7) Bar during the manufacturing process. Additionally, changes starting in 2022 by both Ford and Sogefi align with a lack of similar complaints on MY 2022 and newer vehicles. ODI is opening this Preliminary Evaluation (PE) to evaluate the severity of the potential problem and to fully assess the potential safety-related problems.

  Power Tailgate Release Systems
  STRUCTURE:BODY:DOOR

  In January 2021, the Office of Defects Investigation (ODI) opened a Recall Query (RQ21-001) to assess allegations of post-recall remedy uncommanded tailgate openings in model year (MY) 2017-2019 F-250/350/450 Ford trucks. Besides the recall remedy launched in January 2020, Ford also implemented a production update in November 2019.  At the time of the RQ opening, ODI had received eleven (11) Vehicle Owner Questionnaires (VOQs). ODI sent an Information Request (IR) to Ford in February 2021. In numerous meetings after receiving their IR response, Ford highlighted the drop in claims since the recall and production update and communicated how they were unable to verify the owners’ complaints or replicate the concern. Despite this, Ford began developing ways to prevent uncommanded tailgate openings from various human, mechanical or electrical causes. Based on testing, Ford issued a Customer Satisfaction program, 21M05-S1/S2/S3, to further address the potential of unintended tailgate openings. This work was applied to vehicles being produced as of December 20, 2021.  The program began for already delivered vehicles on July 22, 2022. The covered models include 2017-2022 F-250, 350, 450, 550, 650 and 750 Super Duty and 2020-2022 F-600 Super Duty trucks. ODI has received 39 VOQs between February 24, 2020, and December 15, 2023, alleging uncommanded tailgate openings.  In a detailed analysis, none of the vehicles in the VOQs were found to have received the Customer Satisfaction update. Since ODI has not received any complaints of post-Customer Satisfaction program tailgate openings, this office is closing this Recall Query. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

  Power tailgate opens unintended
  ELECTRICAL SYSTEM:WIRING

  By letter dated December 4, 2019, Ford Motor Company (Ford) notified the Office of Defects Investigation (ODI) of a safety defect that may exist in model years (MY) 2017 through 2019 Ford Super Duty F-250, F-350, F-450 vehicles equipped with an electric tailgate. Following the receipt of five consumer complaints alleging unintended tailgate opening without vehicle operator knowledge, while the vehicles were in motion, NHTSA opened this investigation to assess the manufacturer's data including warranty claims, field reports, design changes, etc.In vehicles equipped with an electric tailgate, water can enter the electrical wiring system and may cause a short circuit resulting in the unintended activation and release of the tailgate latch. This could allow unintended opening of the tailgate while the vehicle is in motion.Analysis of the data provided by Ford found that the frequency of a tailgate opening unintended was high in vehicles equipped with electric tailgates. Unintended tailgate opening without vehicle operator knowledge may result in loss of unrestrained cargo, increasing the risk of a crash. In response to this investigation, Ford decided to conduct recall 19V-864.Owners will be notified by mail and instructed to take their vehicle to a Ford dealer to modify the tailgate/frame wiring harnesses by adding jumper pigtails to isolate the tailgate release control circuits, and will install a new tailgate handle release switch. With recall action 19V-864 taken by Ford Motor Company this investigation is closed. Further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist on other model or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 10984283,11004227,11082643,11090089,11104638,11115381,11140680,11141071, 11141075,11141174,11141200,11141331,11141447,11141547,11141548,11142572, 11142618,11142657,11153541,11153959,11157225,11160936,11165124,11165590, 11166199,11166802,11170049,11171409,11171509,11171685,11180009,11182035, 11186146,11191151,11191353,11193045,11194958,11203615,11206443,11209199, 11229482,11230768,11233349,11233436,11255126,11265643.

  Vehicle Commanded Engine Shutdown
  ELECTRICAL SYSTEM:SOFTWARE

  The Office of Defects Investigation (ODI) opened this RQ to investigate allegations that the scope and remedy of safety recall 13V-535 were inadequate. Recall 13V-535 was limited to a relatively small population of Ambulance Package vehicles and ODI received complaints of pickup trucks and Fire Engine Prep Package vehicles being affected by the same defect. Ford manufactured approximately 555,985 subject vehicles between February 22, 2010 and January 30, 2015 that may be affected by defective EGT sensors and Powertrain Control Module (PCM) software calibration. The subject vehicles are equipped with four (4) EGT sensors to monitor engine operating conditions. An EGT sensor fault may produce false exhaust over-temperature signals. If these signals are produced, the Powertrain Control Module (PCM) implements a Failure Management Effects Mode (FMEM) and the driver receives a Stop Safely Now (SSN) system warning on the instrument cluster message center. The FMEM triggers a 70% reduction in available engine power over a period of no more than 45 seconds, during which it may not be possible to accelerate or maintain vehicle speed. The PCM then commands the engine to shut down when vehicle speed reaches approximately 1 mph. There is no immediate restart capability. Depending on the PCM software calibration, ignition key position and ambient temperature conditions, the engine may not restart until the end of a 10-60 minute cool down period.Ford and its component supplier(s) made numerous changes to the PCM software calibration and the design, material and manufacture of the EGT sensors over the period of subject vehicle production. This continuous product improvement affected vehicle performance regarding the alleged defect. Ford acknowledges the defect condition in the subject vehicles but argues that an unreasonable risk to motor vehicle safety is limited to Ambulance Package and Fire Engine Prep Package vehicles where commanded shutdown could impact emergency response and patient care. Ford also argues that the defect trend is in decline. Ford also initiated a new safety recall (15V-175) to address the 13V-535 remedy concerns in the Ambulance Package vehicles and Fire Engine Prep Package vehicles. The 15V-175 remedy reprograms the PCM with a new software calibration that stops a single EGT sensor fault to cause the vehicle to enter the FMEM shutdown mode.Ford also initiated an EPA emissions recall (14E03) for all subject vehicles that reprograms the PCM with the software calibration employed in safety recall 15V-175. Finally, Ford initiated a Customer Satisfaction Program (15M01) providing extended warranty coverage of 8 years or 80,000 miles for the the EGT sensors on certain MY2011-2012 subject vehicles.Due to the EPA emissions recall, that had a 66.6% completion rate in Ford's December 2015 progress report to the EPA, the defect trend is in decline. ODI is not aware of any crashes, deaths or injuries related to the alleged defect.ODI believes the alleged defect poses a safety risk but notes that the EPA emissions recall is addressing the safety problem.Compelling issuance of a duplicate recall would not represent a wise use of agency resources.Accordingly, this Recall Query is closed.This action is not a finding that no defect exists and NHTSA will take further action if such action is warranted.

  Alleged Loss of Steering
  STEERING

  The Office of DefectsInvestigation (ODI) opened PE13-014 after identifying five complaints alleging steering gear failure in model year (MY) 2008 Ford F-250 and F-350 Super Duty pick-up trucks and to evaluate the relationship between the design history of the steering gear assembly and the alleged defect.As background, ODI investigated steering gear sector shaft fractures in approximately 1.3 million MY 1999 - 2001 Ford Super Duty pick-up trucks and MY 2000 - 2001 Ford Excursion sport utility vehicles in Engineering Analysis EA01-009.The investigation determined that the sector shaft failures were the result of extraordinary, possibly multiple, impacts and not the result of fatigue.No defect in design, manufacturing or materials was identified in the sector shaft.EA01-009 was closed August 19, 2003 with 169 complaints, resulting in a rate of 12.9 incidents per 100,000 vehicles after approximately one year of service.Ford increased the diameter of the sector shaft from 1.375 inches to 1.625 inches at the start of MY 2005 production, increasing the resistance of the steering gear assembly to torsional overload by approximately 48% and changing the failure mode from sector shaft fracture to cracked or broken sector shaft gear teeth.The redesigned steering gear assembly was used in approximately 1.1 million MY 2005 through 2009 Ford Super Duty pick-up trucks, including the subject vehicles.Figure 1 shows the basic steering system design used in Ford Super Duty trucks investigated in EA01-009 and PE13-014. Figure 2 shows the locations of failures resulting from impact related torsional overloading of the sector shaft for the subject vehicles and the prior generation Ford Super Duty trucks investigated in EA01-009.Figure 3 shows an example of a failed sector shaft investigated in EA01-009 and comparisons of fracture surfaces of sector shafts failing from fatigue loading and from torsional overload.Ford provided field return part analysis of failed steering gears from MY 2005 through 2009 Super Duty trucks found evidence of broken sector shaft gear teeth and piston damage consistent with incidents of single event overload (Figure 4).Laboratory analysis found no evidence of fatigue or material property defects in any of the fractures.Analysis of complaint rates by vehicle build month showed no patterns indicating potential manufacturing quality issues and no difference before and after Ford introduced design changes to the input shaft and sector shaft seals in July 2007 to address potential leak concerns (Figure 5).Analysis of failures by time in service indicates a random failure pattern/distribution, consistent with incidents of impact induced overload (Figure 6). The complaint rate for the subject vehicles after approximately 5 to 6 years, 7.1 incidents per 100,000 vehicles, is lower than the rate observed in EA01-009. Furthermore, similar to the condition investigated in EA01-009, a number of incident records include evidence of impact loads (e.g., curb strikes) and several alleged crashes include incidents in which information suggests that the steering gear failure was most likely a result of crash forces, rather than the cause of the crash.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 monitor this issue and reserves the right to take further action if warranted by the circumstances.The ODI complaints cited above can be reviewed at ww
