Ford bulletin SSM 54392

What it saysSome 2021-2025 F-150/Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine may exhibit diagnostic trouble code (DTC) P0299 stored in the powertrain control module (PCM) and may also exhibit a rattle noise… NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Nov 20, 2025, received Dec 1, 2025, about the power train. It names 15 model years across Ford and Lincoln (2021–2025). 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.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication

Some 2021-2025 F-150/Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine may exhibit diagnostic trouble code (DTC) P0299 stored in the powertrain control module (PCM) and may also exhibit a rattle noise from the turbocharger. This may be due to the wastegate actuator rod being disconnected. Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls > Turbocharger has been added to address this condition to allow servicing of the turbocharger actuator rod. In addition, the wastegate actuator rod and associated retention springs and clips have been released as lower level components to complete the repair without replacing the entire turbocharger actuator assembly.

Trouble codes it names: P0299

One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported

Source: NHTSA complaint database

Owners of the 15 model years this bulletin names have filed 3,550 complaints with NHTSA since 2015. 1,342 of them name Power Train, Engine — 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.

On the 2021 Ford F-150, the 85 owners who gave an odometer reading for Power Train reported it at a median of 55,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Passenger side rear axle retention bolt sheared off. Discovered during routine maintenance / tire rotation. Unknown how safety was at risk -- dealer told me once discovered that the vehicle would be repaired under warranty, and they could do in 24 hours, so no discussion about unsafe to drive as others have reported they were told.

2022 Ford F-150 · Power Train · filed with NHTSA Nov 20, 2022

2024 Ford Expedition · Power Train · filed with NHTSA May 25, 2025

I purchased the truck 2 weeks ago brand new and it has a total of 570 miles on it. After not being used for one day, the truck would not start at all. I receive a warning indicating that I should stop safely now, that full power accessory mode is on and a check engine light. I connected a OBD scanner but no codes were generated.

2023 Ford F-150 · Engine · filed with NHTSA Oct 26, 2023

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 579.5

Is Ford SSM 54392 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 54392 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 54392 cover?

The manufacturer filed it against 15 model years across 2 brands (Ford and Lincoln): 2025 Ford Expedition, 2024 Ford Expedition, 2023 Ford Expedition, 2022 Ford Expedition, 2021 Ford Expedition, 2025 Ford F-150 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
