Ford filed this with NHTSA as a service bulletin dated Jan 17, 2026, received Jan 21, 2026, about the electrical system. It names 11 model years across Ford and Lincoln (2024–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

2025 Lincoln Navigator · Electrical System · filed with NHTSA Feb 2, 2026 · ODI 11715174
I had my car in drive in a parking spot. I was ready to go, put the car in drive, DID NOT MOVE but needed to put it in park fast to assist to a child in the back seat. I put it in park pretty fast. Took my seatbelt off and assisted child. It must have not engaged. Car rolled into my office metal mailbox. I 100% put it in park.

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 Ford SSM 54502 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 54502 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 54502 cover?
The manufacturer filed it against 11 model years across 2 brands (Ford and Lincoln): 2026 Ford Expedition, 2025 Ford Expedition, 2026 Ford Explorer, 2025 Ford Explorer, 2026 Lincoln Aviator, 2025 Lincoln Aviator and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
