I own a 2014 Ford Explorer, VIN [XXX]. In approximately 2020, I reported damaged exterior A-pillar appliqué trim clip(s) to a Ford dealer and requested repair. I was told the needed part was on backorder. The condition was not permanently repaired. Ford later issued Safety Recall 24S02 / NHTSA Recall 24V-031 for certain 2011-2019 Ford Explorers involving exterior A-pillar appliqué trim retention clips that can allow the trim to loosen or detach. This is the same or substantially similar condition I reported years earlier. At a later dealer visit, the dealer verified the damaged A-pillar trim. Instead of completing a permanent repair, black duct tape was applied as a temporary measure. I was again told the recall repair parts were on backorder and that I was on a waiting list. The recall repair remains incomplete. I am concerned the exterior A-pillar trim could loosen or detach while driving, creating roadway debris and a hazard to other motorists. I believe the continued delay is unreasonable because I first reported this condition in 2020, the dealer verified it, and the issue is now covered by a safety recall. I request that NHTSA review Ford’s and the dealer’s continued inability to provide the required recall repair and the reliance on duct tape as a long-term temporary measure. I request prompt availability of the correct parts and completion of the recall repair at no cost. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This complaint concerns a failed federal safety recall repair that has resulted in structural damage and rendered my vehicle unsafe to drive. I am the original owner of this vehicle (since XXX). On XXX, Riverside Ford ([XXX]) performed a federal safety recall repair on my vehicle's A-pillars. On January 28, 2026, the vehicle began leaking water. On that day the dealership find the leak due to cracked A-pillar from the clip not holding.In May 2026 I had 4 inches of standing water on the passenger side while in Florida on vacation, and smeared excessive, unprofessional adhesive on the exterior trim. Took it to the dealership the Monday after returned from vacation to have them figure out why it was leaking again. They charged me $218 to have a diagnostic check even though it was part of the recall. Couldn't find any leaks. Took the headliner down. Said that they cleaned out the sunroof tubes but didn't verify if anything ever came out of them. Went back again because of the adhesive that was seeping and dried onto it and you look it's very sloppy. Contacted Ford corporate office opened a case. On XXX, during a another attempt, the dealership replaced the A-pillars again. Upon pickup, the interior sunroof headliner was completely sagging and unseated from its rails. There are massive structural gaps on all sides where I can stick my hand through to the sunroof rails. The dealership service manager, Connie Tell, denied responsibility and refused to let me view the shop video. The vehicle is no longer weather-tight, poses an interior electrical/mildew hazard, and cannot be driven in the rain due to the dealership's faulty execution of a federal safety recall. They also chipped paint off of my vehicle again taking the pillars off to replace them. Connie, when I had mentioned it said you already have paint chips on your car. What difference would it make that's not the point at all. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Both the driver side and passenger side exterior a-pillar applique molding came while driving down the highway and almost caused an accident. This has happened twice because FORD says they can't fix it because they don't have the parts. Anyone can get the parts online that are after market but that does not fix the issue. I did buy the after market ones and those came off on the interstate and almost hit a motorcycle driver. This has been going on Since January of 2024 and FORD is not doing anything about it. You are unable to call FORD, email FORD, and no one will escalate this. Now it has become even more of a safety issues because my rubber seals for my windshield are wearing and tearing off at a fast pace. It is causing more damage that FORD will not be responsible for fixing. Why do safety recalls not get fixed and are not forced to be fixed? Safety recall and no one cares to get it fixed.

PE23001 · 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. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

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

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.
