Official summary
Some 2018-2020 Navigator vehicles may exhibit excessive oil consumption with no visible oil leaks with or without diagnostic trouble code (DTC) P0365 and/or P0369. Engineering is working to implement a PCM calibration update for this condition. In the interim, clear the DTCs with the appropriate Ford scan tool, top off the oil to the top of the full range on the dipstick and schedule a follow-up appointment with the customer for late July 2020. Advise the customer that a repair is expected to be available in July and remind customers to follow the Owner's Manual to check oil level.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
