What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025 Navigator vehicles may set diagnostic trouble code (DTC) U0415 in the power steering control module (PSCM) when a diagnostic self-test is performed. This may be due to PSCM DTC sensitivity during vehicle key on/start-up. Replacement or reprogramming of the PSCM will not resolve this condition. U0415 should be ignored and no further service action is required if no other DTCs are present in the PSCM, no warning indicators are illuminated while the engine is running, and no symptoms present.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 12 complaints with NHTSA since 2015. 2 of them name Steering — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 53864 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 53864 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 53864 cover?
The manufacturer filed it against 1 model year: 2025 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
