Front Brake Hose Failure
On April 29, 2015, the Office of Defects Investigation (ODI) opened PE15-017 to investigate a report alleging incidents of front brake hose failure in model year (MY) 2015 Ford Explorer Police Interceptor vehicles used by the Sacramento Police Department in its pursuit driving training program (VOQ 10705832).On September 28, 2015, ODI upgraded the investigation to an Engineering Analysis (EA15-005) to assess maximum front caliper crimp temperatures under various test conditions, test hose assemblies removed from police interceptor service for any signs of thermal degradation, and further assess field data for evidence of a defect trend related to the alleged defect.The alleged defect results from exposure to extremely high heat at the caliper-side hose crimp. NHTSA?s vehicle testing suggests that the conditions necessary to produce the critical temperatures in the subject components result from drive-soak intervals that can occur during the Sacramento training program.NHTSA's testing of hose assemblies returned from police interceptor service did not identify any evidence of thermal degradation.NHTSA has not confirmed any incidents of caliper crimp failures due to overheating in ve
Exhaust Odor in Passenger Cab
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
Front brake hose failure
On April 29, 2015, the Office of Defects Investigation (ODI) opened PE15-017 to investigate reports of low-mileage failures of front brake jounce hoses in model year (MY) 2015 Ford Explorer Police Interceptor vehicles operated as training vehicles by the City of Sacramento, California (ODI VOQ No. 10705832). To date, the Sacramento police fleet has reported a total of 7 front hose failures in 5 different Explorer Police Interceptor vehicles used for its Emergency Vehicle Operation Course (EVOC) training. Most of the failures occurred within the first few miles of service on a closed course used for the EVOC program, which includes evasive accident avoidance and pursuit maneuver training. The hose assemblies either leaked at, or pulled completely free from, the caliper-end attachment where the hose is crimped to the steel end fitting. Most of the failures resulted in a sudden loss of braking performance that caused the vehicle to run off the intended course. None of the failures resulted in any crashes, injuries or property damage.The subject MY 2015 hose assemblies are similar in design to hoses used on MY 2013 through 2014 Explorer Police Interceptor and civilian vehicles. The 5 v
Ford Explorer Exhaust Odor
During the National Highway Traffic Safety Administration?s (NHTSA?s) investigation into the Ford carbon monoxide allegations, the Office of Defects Investigation (ODI) identified additional Vehicle Owner Questionnaire (VOQ) reports with similar exhaust odor claims.Presently, ODI has identified 791 VOQs for Model Year 2011-2017 Ford Explorers pertaining to exhaust odor claims.ODI has identified three crashes and 41 injuries potentially linked this issue.The reported injuries range from unspecified to loss of consciousness, with the majority being nausea, headaches, or dizziness ? all of which can be symptomatic of carbon monoxide exposure.Additionally, Ford provided 2,400 reports including owner complaints, warranty claims, dealer field reports, and legal claims, that involve 2,051 vehicles that may be connected to the exhaust odor issue.NHTSA's Vehicle Test and Research Center tested multiple vehicles, including complaint vehicles, during the investigation.ODI also conducted field inspections of complaint vehicles and crashes involving police units that occurred while the officers were on duty.When possible, data was collected to quantify carbon monoxide levels in the examined veh
Windshield trim molding Item detachment
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 ODIâs 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
Hertz/Vehicles Rented with Open Recalls
NHTSA is opening this audit query to investigate whether The Hertz Corporation (Hertz) has complied with the requirements of the National Traffic and Motor Vehicle Safety Act (Safety Act). The Safety Act requires, among other things, that a rental company shall not rent a vehicle subject to a safety recall unless the recall remedy has been performed. 49 U.S.C. § 30120(i).NHTSA is in receipt of information that indicates Hertz rented vehicles to customers without having performed required recall repairs. Accordingly, we are opening this audit query to seek additional information concerning this issue.
Underbody shields detachment
The Office of Defects Investigation (ODI) received a petition on August 22, 2025, requesting a defect investigation into an alleged defect of the âunderbody shieldsâ on model year (MY) 2020 Ford Explorer vehicles. The petition alleges premature degradation and detachment of the plastic underbody shields, potentially leading to road debris. The petition itself can be reviewed at NHTSA.gov under ODI number 11682326. A search of the subject vehicle population was undertaken using complaints submitted to ODI. No related complaints were found in NHTSAâs database for the subject vehicle population. Subsequently, ODI conducted a broader search for related complaints and field reports involving MY 2020-2025 Ford Explorer and Lincoln Aviator models, as these vehicles utilize substantially similar underbody shields. No complaints or reports were found citing any allegations pertaining to any of the underbody shields. ODI also reviewed manufacturer information and data and did not identify a trend related to the Petitionerâs allegations. Based on the absence of consumer complaints and reports, ODI has not identified a material risk of a complete detachment or a projectile hazard relat
Rearview Camera FMVSS 111 Noncompliance
On September 23, 2020, Ford Motor Company (Ford) filed a noncompliance recall report under 49 CFR Part 573 (NHTSA Recall No. 20V-575), recalling 620,246 Model Year (MY) 2020 Ford F-150, F-250, F-350, F-450, F-550, Explorer, Mustang, Transit, Expedition, Escape, Ranger and Edge, and Lincoln Nautilus and Corsair vehicles for a noncompliance with Federal Motor Vehicle Safety Standard (FMVSS) 111, Rear Visibility. Ford's recall described the noncompliance as insufficient electrical conductivity within the printed circuit board (PCB) internal to the camera leading to intermittent rearview camera operation. The supplier of the cameras was Magna Electronics.According to Ford's chronology in the Part 573, during the period February-April 2020, Ford identified and monitored warranty claims pertaining to intermittent or inoperative rearview cameras. Ford reviewed supplier product changes, focusing on changes introduced by the supplier in the October-November 2019 time frame. The Part 573 stated that the issue was brought to Ford's Critical Concerns Review Group (CCRG) for review on May 12, 2020.On July 7, 2020, NHTSA's Vehicle Research and Testing Center (VRTC) informed the Office of Defects
Rear Axle Bolt Failure
On July 17, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 2 consumer complaints alleging loss of vehicle forward power and/or loss of transmission torque of the rear wheels in model year (MY) 2020-2022 Ford Explorer vehicles (subject vehicles). The RQ was opened to focus on the effectiveness of the remedies of Recalls 22V-255 and 23V-199 related to the alleged problem. Recall 22V-255 involved replacing the bushing and axle cover in the following subject vehicles: 3.3L FHEV Police built before October 14, 2020, and 3.3L Gas Police vehicle built before January 31, 2021. For 2.3L RWD, 3.0L PHEV, 3.3LFHEV, and 3.0LST retail (non-police) vehicles, the recall provided an PCM software update to engage the Electronic Park Brake (EPB) when Park is commanded. The recall addressed a breakage of the rear axle bolt that can cause the driveshaft/half shafts to disconnect, resulting in a loss of transmission torque to the rear wheels necessary to hold park. If the parking brake is not applied, the loss of the primary park torque will allow the vehicle to roll in park increasing the risk of crash and injury. Recall 23V-199 addressed 674 of the subject
Loss of Motive Power
On July 22, 2022, the Office of Defects Investigation (ODI) granted a Defect Petition (DP22001) and opened a Preliminary Evaluation (PE22007) to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco vehicles equipped with 2.7L EcoBoost engines. Complainants were reporting sudden engine failure while driving resulting in a loss of motive power, often without the ability to restart. During PE22007, the cause of engine failure and loss of motive power in the subject vehicles was determined to be intake valve fracture, and the full scope of vehicles affected by the subject defect was identified as all MY 2021-2022 Ford and Lincoln models equipped with either the 2.7L or 3.0L EcoBoost engines, referred to as the âNanoâ engine family. If an intake valve fractures in the subject engines, it may drop into the cylinder and contact the piston, often resulting in catastrophic engine damage. On September 29, 2023, PE22007 was upgraded to an Engineering Analysis (EA23002) to further investigate the subject defect across the full scope of affected vehicles. During EA23002, ODI visited Ford facilities to review technical information related to intake valve frac
