EXPLORERProblems & recalls

On January 27, 2023, the Office of Defects Investigation (ODI) opened PE23-001 to investigate allegations of A-pillar trim panel detachment on model year (MY) 2011-2019 Ford Explorer vehicles. At the time of opening, the office had received 164 Vehicle Owner Questionnaires (VOQs) reporting this failure. ODI has received 671 VOQs regarding this failure, including 1 alleged crash and 2 alleged injuries. Some consumers have reported that the failure occurred while they were driving at highway speeds, with the detached trim panel entering the path of travel of the vehicle behind them, requiring the driver of the following vehicle to take evasive action. It is noteworthy that motorists who experience this type of road hazard are less likely to accurately identify the subject vehicle the item detached from and report the event to the NHTSA. In its April 17, 2023 response to ODI’s information request, Ford provided 175 consumer complaints (including field reports) and 14,162 warranty claims related to A-pillar trim panel detachment. Ford relayed that the subject vehicles utilize a plastic A-pillar bracket, which is bolted to the vehicle structure during assembly. The A-pillar trim panel is attached to the bracket utilizing 7 plastic clips. Contributory factors which have been identified by Ford as leading to the subject defect include incomplete installation at the assembly plant, inadequate part stack up, damage to fasteners during installation, and failure to follow proper repair procedure during windshield replacements or other services. On January 19, 2024, Ford filed safety recall 24V-031 for MY 2011-2019 Ford Explorer vehicles to address the subject defect. In the Part 573 Safety Recall Report, Ford identified that a detached A-pillar trim panel can create a road hazard for other road users, increasing the risk of a crash. The recall remedy includes an inspection of the existing A-pillar trim panel and, if necessary, the replacement of the component. The remedy A-pillar trim panels will be installed with an additional adhesive for robustness and utilize an inspection procedure to ensure full engagement of all the retention clips during installation. In view of the recall action being taken by Ford, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

During the EA17-002 investigation, the agency reviewed and analyzed reports of exhaust odors in the passenger cabins of Model Year 2011 to 2017 Ford Explorers. This investigation required an approach that incorporated knowledge and expertise from the automotive, medical, environmental health, and occupational safety fields. The agency conducted an in-depth investigation that encompassed the review of over 6,500 consumer complaints, conducting field inspections, and testing the relevant vehicles, both independently and in coordination with Ford and other entities. During the investigation, the evolution of Ford service bulletins intended to reduce the level of exhaust odors and carbon monoxide (CO) entering the occupant compartment was examined and independent tests to evaluate the effectiveness of the final Field Service Actions (FSA) for both consumer and police vehicles were conducted. As part of the investigation, the agency also examined the effects of cracked exhaust mani-cats on the measured CO levels in the vehicles and tested the FSA repairs to ensure they did not adversely impact occupant compartment CO levels due to cracked mani-cats.The investigation identified upfitting issues for Police Interceptor vehicles. Upfitting (sirens, lights, cages, auxiliary power, etc.) is typically performed by governmental fleet operations, independent repair facilities, or local Ford dealers after the sale of the new vehicle. Sealing issues caused by upfitting were responsible for the highest measured carbon monoxide levels in tested vehicles. The police FSA instructs how to inspect the quality of the vehicle upfits and how to properly seal any leaks caused by these upfits, at no cost to the police agency. Similarly, the highest CO levels measured in consumer vehicles were usually traced to sealing issues caused by rear crash damage where the repairs did not ensure sealing integrity. The most recent Ford FSA procedure for both the police (17B25) and consumer vehicles (17N03) includes an HVAC reprogramming operation. Tests by Ford and NHTSA have demonstrated a substantial reduction of CO levels due solely to the HVAC reprogramming. Other FSA repairs also demonstrated measurable contributions to CO level reductions during controlled tests.Throughout the investigation, vehicles accurately measured with higher levels of carbon monoxide were almost always affected by upfitter alterations, damage, or other causes compromising rear passenger cabin seals.NHTSA received thousands of reports alleging odors which triggered a variety of physiological responses, predominately nausea, headaches, and lightheadedness. NHTSA focused the investigation on accurately measuring vehicle CO levels, and accurately measuring carboxyhemoglobin (COHB) levels from properly administered blood tests. Using rigorous test methods to produce exhaust gas intrusion in vehicles with a properly performed FSA, occupant compartment CO levels remained below current environmental limits for CO in any environment (EPA ambient air quality standards). Furthermore, even without FSA repairs, no vehicles unaffected by upfitter issues or prior crash damage were identified with CO levels that exceed accepted occupational CO exposure levels. This investigation finds that the 2011-2017 Ford Explorer vehicles when accurately measured produce occupant compartment CO levels which fall below current accepted health standards, and could not identify COHB levels for vehicle drivers or other occupants, which exceeded thresholds for acute physiological effects. Therefore, the agency has not identified a defect that represents an unreasonable risk to motor vehicle safety.This inve

On May 27, 2014 and amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist in approximately 179,027 model year (MY) 2011 through 2013 Ford Explorer vehicles equipped with electric power assisted steering (EPAS), including 82,328 MY 2011 Explorersthat are the subject of PE12-017.Ford has assigned the recall number 14S06.The NHTSA recall number is 14V-286.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Sudden loss of power steering assist while driving can occur in the subject vehicles if the system loses electrical power or whenever the system detects a fault that requires it to enter fail-safe mode, which removes power from the EPAS motor and defaults to manual steering.Ford's DIR indicates that the majority of steering assist failures in the recalled vehicles have been caused by an intermittent electrical connection in the Power Steering Control Module (PSCM) that can lead to a loss of the motor position sensor signal.Ford's remedy instructs dealers to check the PSCM for diagnostic trouble codes (DTC).If upon initial inspection a loss of steering assist DTC is present, dealers will replace the steering gear at no charge to the owner and update the PSCM with revised software.Following detection of a motor position sensor signal fault, the revised software will provide audible and visual warnings to the driver that a power steering system fault has been detected and will maintain steering assist for the remainder of that drive cycle.If no DTC is present, dealers will reprogram the PSCM with the revised software. Analysis of information from all sources identified a total of 969 complaints and 4,059 warranty claims related to loss of power steering assist while driving in the MY 2011 through 2012 Explorer vehicles, resulting in a complaint rate of 5.4 incidents per thousand vehicles and a warranty claim rate of 2.3 percent.ODI identified 15 crashes with evidence indicating loss of power steering assist may have been a factor.All 15 crashes involved low-speed impacts with roadside objects during turning maneuvers, resulting in minor vehicle damage or no damage.In one incident that occurred in a low-speed curve, the driver attempted to brake in response to the sudden increase in steering effort and inadvertently applied the accelerator pedal instead.This caused the vehicle to run off the side of the road and strike a wooden pole at approximately 15 mph.Another incident occurred when the driver was unable to to negotiate a left-turn at an intersection and ran off the road into a shallow ditch, resulting in moderate front-end damage to the vehicle and minor injuries to the driver that did not require medical treatment. This investigation is closed.All ODI complaints associated with this closing resume are listed in the Attachment 1.
