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 22 model years this bulletin names have filed 1,045 complaints with NHTSA since 2015. 153 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.
The contact owns a 2022 Mazda MX-5. The contact stated that while the vehicle was in operation, the rooftop failed to remain sealed opened or closed as intended, causing the alarm system to be disarmed. The contact stated that the vehicle would not move forward or backward while shifted into gear. There was no warning light illuminated.

On 14th, 2026, while traveling at approximately 60 mph on the northbound 55 Freeway near the Katella exit, my vehicle suddenly began to shake violently without any prior warning. In response, I attempted to slow down by applying the brakes; however, the speedometer rapidly increased even as I maintained firm pressure on the brake pedal.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda SA-031-24 a recall?
No. A manufacturer communication 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-031-24 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-031-24 cover?
The manufacturer filed it against 22 model years: 2024 Mazda CX-30, 2023 Mazda CX-30, 2022 Mazda CX-30, 2024 Mazda CX-5, 2023 Mazda CX-5, 2022 Mazda CX-5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
