What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 F-150 vehicles may exhibit a condition where the volume is limited to 14 with a "MyKey volume limited" message in the center display screen. To resolve this concern, disconnect the vehicle's 12-volt battery cables for 10 minutes and reconnect. For hybrid vehicles, disconnect the vehicle's primary 12-volt battery and the auxiliary battery located under the rear seat. Refer to Workshop Manual (WSM), Section 414-01. If a battery reset does not resolve this solution inform customers that engineering is currently working on a solution. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If a customer's vehicle exhibits this concern, submit a Vehicle Concern Report. To submit a report, click on the "Submit Global Concern Report (GCR)" link at the upper right of the PTS Vehicle ID screen (vehicle identification number ÝVIN¨ required) and fill out the form. Include the article number of this message in the text of the form. Do not use the "Report A Problem" link to submit a report for this condition.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54838 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 54838 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 54838 cover?
The manufacturer filed it against 1 model year: 2024 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
