Ever since I purchased my 2014 Ford Explorer, I noticed a foul smell inside the vehicle when accelerating. It seemed fine when driving normally, but when accelerating into traffic or whenever RPMs are increasing, it’s definitely noticeable. At first I thought it wasn’t that big of a deal, until my young step-son was in the passenger seat complaining about how he felt nauseous out of nowhere.

4PE23001 · Windshield Trim Molding Item Detachment
Opened Jan 27, 2023 · Closed Feb 8, 2024
Status: closed (inferred from source dates) · Structure:body:roof And Pillars
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.

EA17002 · Exhaust Odor In Passenger Cab
Opened Jul 27, 2017 · Closed Jan 17, 2023
Status: closed (inferred from source dates) · Engine And Engine Cooling:exhaust System:manifold/header/muffler/tail Pipe; Structure:body
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

EA15005 · Front Brake Hose Failure
Opened Sep 28, 2015 · Closed Nov 2, 2018
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings
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 vehicles not subjected to the Sacramento training course driving.The low number of hose assembly failure reports and the absence of any verified incidents of heat related front brake hose crimp failures since 2015 suggests that the Sacramento PD incidents resulted from conditions unique to the training program.A safety related defect trend 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 the circumstances.For additional information, see the Closing Report in the document file for EA15-005 on www.nhtsa.gov.
