What owners reported
Source: NHTSA complaint databaseOwners of the 32 model years this bulletin names have filed 1,556 complaints with NHTSA since 2015. 369 of them name Engine, 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.
The vehicle exhibits a repeatable low-speed driveline-related problem consisting of pronounced clicking or clunking from the driver-front area, fore-and-aft jerking, and harsh engagement during deceleration and light on/off-throttle transitions, particularly around 15–17 mph; the behavior can become significantly worse over rough or…
2025 Mazda CX-5 · Engine · filed with NHTSA Aug 23, 2026
Low Engine Oil Light keeps appearing at seemingly random intervals. I will heat up my vehicle, begin driving, and sometimes after 10 minutes, sometimes after 20 minutes it will come on. I drove 2.5 hours and it did not come on at all. It first started Friday 11/29 and was driven to and from a few places and came on 50% of the time.
2020 Mazda CX-30 · Engine · filed with NHTSA Dec 3, 2024
I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving.

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 SA-023-25a 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-023-25a 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 SA-023-25a cover?
The manufacturer filed it against 32 model years: 2025 Mazda CX-30, 2024 Mazda CX-30, 2023 Mazda CX-30, 2022 Mazda CX-30, 2021 Mazda CX-30, 2020 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.
