Mazda filed this with NHTSA as a service bulletin dated Dec 12, 2023, received Jan 5, 2024, about the equipment. It names 3 model years (2022–2024). 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 communicationSome customers may experience no sound from the audio system and/or the audio source cannot be changed. This concern may be caused by the remote tuner not operating properly under certain situations. To eliminate this concern, the remote tuner control software has been modified.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 441 complaints with NHTSA since 2015. 71 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.

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 Mazda 09-039-23a 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 09-039-23a 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 09-039-23a cover?
The manufacturer filed it against 3 model years: 2024 Mazda CX-90, 2023 Mazda MX-30, 2022 Mazda MX-30. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
