Ford E-450 Investigations

6 ODI actions on file.

• RQRQ24003CLOSEDOpened 2/27/2024
  Loss of Power Brake/Steering Assist Post Recall 22V089 Inspection.
  SERVICE BRAKES, HYDRAULIC:POWER ASSIST

  The Office of Defects Investigation (ODI) opened Recall Query (RQ) 24003 on February 27, 2024, to evaluate the scope and remedy effectiveness of NHTSA recall 24V097. On February 16, 2022, Ford Motor Company (Ford) issued a safety recall, NHTSA recall 22V089, for certain 2021-2022 Ford E-350 and E-450 vehicles equipped with dual rear wheels. According to the filing, specific hydraulic lines could leak resulting in a sudden loss of power steering and power brake assist, increasing the risk of a crash. The remedy involved a dealer inspection of the lines and their replacement as necessary. Only vehicles that failed the inspection received updated parts. On February 9, 2024, Ford issued a new recall, NHTSA recall 24V097, to replace the specific hydraulic lines on any vehicle that had not yet been inspected and on any vehicle which had passed inspection within the previous twelve months. However, vehicles which had passed the inspection more than twelve months ago would not be included within the scope of the new recall, as Ford deemed them to have a low likelihood of failure. ODI opened this RQ to better understand Ford's scoping of recall 24V097, specifically concerning the inspected-only vehicles not included in the new recall filing. ODI sent Ford an information request letter on April 18, 2024. Ford responded, in full, on May 31, 2024. ODI reviewed Ford's data which showed that the vehicles not included in the new recall had a predicted failure rate of less than 0.25% within 10 years from the date of inspection. By comparison, the vehicles included in the new filing have had a failure rate of approximately 2% prior to being recalled again. ODI analysis of complaint and warranty data further supports Ford's assessment that vehicles that passed inspection more than twelve months prior to recall 24V097 are unlikely to experience the defect condition. ODI is closing this RQ without a manufacturer action. 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.

  Trimark 060-1650 Door Latch Failures
  EQUIPMENT

  On November 23, 2020, the Office of Defects Investigation (ODI) opened PE20021 to investigate allegations of inoperative Trimark THP 060-1650 door lock/latches originally equipped on model years (MY) 2015-2017 Class A and Class C motorhomes.ODI received forty-six Vehicle Owner’s Questionnaires (VOQs) describing consumers being locked in or out of their vehicles.The door latch, containing a die-cast zinc plunger, was produced by Equality during calendar years 2014-2016. The die-cast may become porous and brittle over time and can break without warning, causing the vehicle owner to be unable to open the recreational vehicle door equipped with the latch.If the motorhome does not have any other doors such as some Class A models, occupants could be trapped inside, needing to climb out using the emergency exits. If locked out, owners would be unable to easily get in and retrieve children and pets. ODI analyzed the data provided by Trimark in response to its January 27, 2021 information request letter.Although an elevated failure rate was evident on a specific combination of plunger bolt, door lock/latch assembly and door, the data showed that most failures occurred within the first two years of service on the affected 2015-2017 vehicles.This data suggests that component failures generally would have already occurred.Further, ODI data reflects a downward trend in complaints after calendar year 2018 and for post- MY 2016 vehicles.This downward trend may be attributed Trimark's actions in 2016 such as changes in the manufacturing process of its zinc plunger component for the relevant population and its 2016 decision to switch to a steel plunger. In view of the nature of early-life failure, and failure rate trending downward for model years 2017 and newer, this Preliminary Evaluation (PE) is closed.  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.

  Internal transmission failure
  POWER TRAIN:AUTOMATIC TRANSMISSION

  By letter dated June 10, 2019, Ford Motor Company notified the Office of Defects Investigation (ODI) of a safety defect that may exist in certain model year (MY) 2009 through 2016 Ford Econoline vehicles equipped with a 5R110W transmission. Following the receipt of consumer complaints alleging transmission failures in vehicles built with a 5R110W transmission, NHTSA opened this investigation to assess the manufacturer's data including warranty claims, field reports, design changes, etc.Vehicles equipped with a 5R110W transmission contain a capacitive discharge weld within a coast clutch component in the transmission. A substandard weld may fatigue and fail, causing an elevated rate of loss of motive power in subject vehicle applications. Reports indicate that most of the weld failures occur when the torque is highest, which is when the driver attempts to accelerate from a stop.Analysis of the data provided by Ford Motor Company found that the risk of a transmission failure is very high in vehicles equipped with the combination of a W-MOD 5.4L SOHC EFI NA V8 G-NP engine and a 5R110W transmission. This vehicle population mainly consists of school buses and ambulances. A loss of mobility in school bus applications may result in the transfer of children when the vehicle is immobilized in a roadway, and a loss of vehicle mobility in ambulance applications may result in the delay of patient treatment.In response to this investigation, Ford Motor Company agreed to conduct recall 19V-432. Owners will be notified by mail and instructed to take their vehicle to a Ford or Lincoln dealer to have the coast clutch cylinder replaced and to replace the single-engaging coast one-way clutch with a dual-engaging one-way clutch. With recall action 19V-432 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.

  HVAC Switch Failures
  ELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASH

  ODI has received 1 complaint and reports from 4 transportation fleets alleging 182 switch failures.Each fleet operates mini buses built on a Ford E350 or E450 cutaway chassis.The OEM HVAC blower switches have melted, smoked, burned or experienced open flame and become inoperable on vehicles in each fleet.Some drivers have reported a burning smell or smoke coming from the dash.One fleet reported a vehicle fire.No injuries were sustained.However, the bus was carrying special needs children when the driver noticed smoke coming from the dash.The driver was able to evacuate the children prior to the vehicle becoming engulfed in flames.This PE has been upgraded to an Engineering Analysis (EA) to determine if the blower motor switch failures create a situation where a vehicle fire is possible and presents a safety risk to the driver and other passengers.

  RAPID TIRE DEFLATION
  TIRES

  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.
