What owners reported
Source: NHTSA complaint databaseOwners of the 37 model years this bulletin names have filed 1,653 complaints with NHTSA since 2015. 615 of them name Engine, Electrical System, Exterior Lighting — 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.
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-023-25c 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-023-25c 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-023-25c cover?
The manufacturer filed it against 37 model years: 2026 Mazda CX-30, 2025 Mazda CX-30, 2024 Mazda CX-30, 2023 Mazda CX-30, 2022 Mazda CX-30, 2021 Mazda CX-30 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
