What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some customers may experience that the fuel lid and charge lid do not lock or unlock during door lock/unlock operation. This is caused by: Improper dimensional accuracy of the lid actuator lock mechanism Incomplete control logic in the R-ESU software To eliminate this concern: The mold design of the lid actuator was modified. The control software of the R-ESU was revised.

Read by machine from the document NHTSA serves (8 pages), read Sep 30, 2026. A part number is shown only where it matches Mazda’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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 21 model years this bulletin names have filed 1,141 complaints with NHTSA since 2015. 20 of them name Structure — 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.
Door handle cables detach easily which prevents the door from being opened from the inside. It has happened to me twice on my driver side door the last 5 months. Research online shows this is a very common problem with newer Mazdas and it is a major safety hazard as it prevents easy exit from the vehicle in the event of an emergency…
2025 Mazda CX-50 · Structure · filed with NHTSA May 2, 2026
Keyless Entry: I have had this vehicle for about 6 months and over that time, more than 3 separate times the keyless entry hasn't unlocked. It may take 2 - 3 tries. It has never failed to eventually unlock. I don't know that it ever failed to lock because approaching the car it would have already been unlocked.
2023 Mazda CX-50 · Structure · filed with NHTSA Feb 20, 2024
Door gap between the driver's side door and the driver side rear door is too small. When temperatures exceed 75 degrees f and the car is parked in direct sunlight, the door expands and it will rub onto the rear door b pillar weatherstripping. Door becomes hard to open from the inside when this happens.
2019 Mazda Mazda3 · Structure · filed with NHTSA May 4, 2020
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 09-045-25 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 09-045-25 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 09-045-25 cover?
The manufacturer filed it against 21 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. The document itself sets the build window: built before 3 Apr 2025; built before 20 Apr 2024; built before 3 Apr 2024 — the build date is on the certification label in the driver’s door jamb.
