The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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 databaseOwners of the 3 model years this bulletin names have filed 147 complaints with NHTSA since 2015. 48 of them name Service Brakes, 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.
The vehicle had the original OEM battery fail at 15 months. It dropped to 7v under light load. It's a bad battery. Upon being jump started, the power steering went in and out while driving and the dashboard blinked on and off...throwing a lot of errors that are unrelated to the battery problem.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda SA-072-24 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 SA-072-24 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. Every Mazda warranty extension on file lists the ones Mazda has filed.
Which vehicles does SA-072-24 cover?
The manufacturer filed it against 3 model years: 2025 Mazda CX-50, 2024 Mazda CX-50, 2023 Mazda CX-50. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built before 3 Mar 2022 — the build date is on the certification label in the driver’s door jamb.
