What NHTSA says
Source: Office of Defects Investigation, as filedBackground In a Part 573 Safety recall report dated August 11, 2015, Marmon-Herrington notified NHTSA that it decided that a defect exists in certain drive axles, model numbers MT14, MT17, MT22, R17 and R22, manufactured July 28, 2014, to July 22, 2015. The affected axles are equipped with hex nuts on the flange yoke that may not have been properly tightened. If the hex nuts are not tightened to specification, the driveshaft may disconnect from the drive axle, resulting in a loss of propulsion and increasing the risk of a crash. This matter was assigned recall campaign number 15E-065. In their 573 Defect Notification Report, Marmon-Herrington identified several vehicle manufactures that were sold and possibly installed the defective axles in their vehicles. On March 15, 2016, the Recall Management Division (RMD) opened this Equipment Query (EQ) Investigation in order to obtain Marmon-Herrington's customer list and to contact the companies that purchased the defect drive axles, notify them of the defect and ensure thorough safety recalls are conducted where appropriate. On March 15, 2016, an information request letter was sent to Marmon-Herrington via email. A second information request letter was sent to Marmon-Herrington on April 5, 2016. Marmon-Herrington?s ResponseMarmon-Herrington responded to the information request letter on April 8, 2016.

A Equipment Query is a query about a piece of equipment — a component, a tire, a child seat — rather than a whole vehicle. The summary is the agency’s own text from its investigation file, unedited; the resumes carrying the full reasoning are linked below.

These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.
