What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 98 complaints with NHTSA since 2015. 20 of them name Electrical System — 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.
This vehicle has been returned to service 5 times. It is currently in service for the same 4 issues that it was taken to service for the very first time on 12/10/2025. This includes inappropriate braking on the interstate, driver window malfunction, the key intermittently stops working, and the connectivity does not regularly work.
2025 Lincoln Navigator · Electrical System · filed with NHTSA Feb 2, 2026 · ODI 11715174
During a short drive between and roughly 27 miles, the red battery light on the dash display illuminated just as we were turning into the Holiday/Circle K gas station in . No other warnings or messages appeared on the dash, and upon restart after returning to the vehicle, the red battery light did not reappear.
2025 Lincoln Nautilus · Electrical System · filed with NHTSA Aug 28, 2026 · ODI 11760280
Multiple loss of power, misfires, rough running and abnormal shifting. These events have put my family and I at risk as well as posing a significant risk to other drivers sharing the road due to the sudden loss of power while on the highway. Lincoln is dismissive and not taking this seriously.
2025 Lincoln Aviator · Electrical System · filed with NHTSA Sep 15, 2026 · ODI 11764477
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

No. A over-the-air update 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 PHX-25.1.2.4 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does PHX-25.1.2.4 cover?
The manufacturer filed it against 4 model years: 2025 Lincoln Aviator, 2025 Lincoln Nautilus, 2024 Lincoln Nautilus, 2025 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
