What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome vehicles equipped with the Blind Spot Monitoring (BSM) may show the BSM indicator light is on in the outer door mirror, even if there are no vehicles in the alert area. This concern is caused by improper control logic of the side radar sensors. False detection may occur while driving. To eliminate this concern, the control software of the side radar sensors has been modified.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 12 complaints with NHTSA since 2015. 2 of them name Visibility/Wiper — 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.
Front and rear windshields get excessive condensation on the inside of windows obstructiing visibility. Car taken to dealer and they could not reproduce the same situation. This puts others at risk because the defroster does not work well when there is heavy condensation on the inside of the windows.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 15-004-23 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 15-004-23 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 15-004-23 cover?
The manufacturer filed it against 1 model year: 2024 Mazda Mazda3. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
