NHTSA investigation RQ16001 is a Recall Query opened on 2016-09-28 and currently closed. The subject of record is FORD F-150, which places this file inside the Office of Defects Investigation queue for FORD.

A Recall Query like RQ16001 evaluates whether a previously issued recall is actually fixing the problem. NHTSA opens an RQ when owners continue to report the original defect after the recall remedy is installed, or when completion rates fall short of the agency's expectations for that risk tier.
Investigators summarized the matter as follows: "On June 8, 2020, Ford Motor Company issued a safety recall (NHTSA Recall No. 20V-332) of 292,311 model year (MY) 2014-2017 Ford F-150 vehicles equipped with 3.5L Ecoboost engines and built from 9/1/2014 to 8/1/2016. Ford..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related FORD files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
On June 8, 2020, Ford Motor Company issued a safety recall (NHTSA Recall No. 20V-332) of 292,311 model year (MY) 2014-2017 Ford F-150 vehicles equipped with 3.5L Ecoboost engines and built from 9/1/2014 to 8/1/2016. Ford stated that the causes of brake fluid loss in the master cylinder are brake fluid contamination that can interfere with rear cup seal function, and rolling of the rearmost cup seal. Prior to total loss of the front brakes, depending on the amount of brake fluid loss in the master cylinder, the driver may receive an audible chime, message center alert and red brake warning indicator in the instrument cluster, and may experience a change in brake pedal travel and increased pedal effort. It should be noted that a small number of late-built MY 2014 and early-built MY 2017 F-150 vehicles are included in the recall along with the subject vehicles (MY 2015-2016). This Recall Query is closed based on the safety recall issued by Ford.
