NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE19-016.
The Office of Defects Investigation (ODI) opened this PE on November 12th, 2019 after receiving 2 consumer complaints alleging the aerial turntable on their 2013 KME fire trucks were supplied from the manufacturer without lubrication. When inspected, it was found that some of the turntable internal gears had seized and other gearbox internals were severely corroded and pitted due to lack of lubrication.
ODI interviewed the two complainants and received documentation showing failed gearing and drive-planetaries due to a lack of lubrication. In addition, ODI visited the manufacturer's assembly plant to learn about the drive system and how it is received from the supplier Kraft Hydraulics. ODI learned the electric motor and apparatus are shipped dry. The system is then painted by KME prior to assembly on the fire truck when lubrication is then supposed to occur. KME has acknowledged the missed production step of filling the turntables with lubricating oil after installation on the vehicle. The turntable gearbox is supposed to contain lubricating oil to reduce friction and protect internal gears from corrosion. If the turntable was not filled with lubricating oil, it may seize or freely traverse without control, possibly striking objects and potentially endangering fire fighter safety.
As part of the safety recall, KME will inspect and verify if the turntables contain lubricating oil. If not, they will be sent to the manufacturer for rebuild. If the owner has already incurred costs to remedy this issue, they will be directed in the notification letter to contact KME for reimbursement.
This Preliminary Evaluation has been closed with a voluntary safety recall released by the manufacturer (20V-006).

Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE19-016. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
