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 notice an abnormal noise (i.e. whine, groan, rattle or squeak) coming from the front combination lights when turning them on, or a few minutes after turning them off. The noise may be due to contamination by foreign matter during the manufacturing process. The fan motor bearing may become worn out during use. To eliminate the noise, the production process at the supplier and the material has been modified. NOTE: It is normal for some noise to occur within the first few seconds after starting the engine, when the front combination lights perform a self check (sweep).

Read by machine from the document NHTSA serves (6 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 09-015-23a 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 09-015-23a 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 09-015-23a cover?
The manufacturer filed it against 7 model years: 2022 Mazda CX-30, 2021 Mazda CX-30, 2020 Mazda CX-30, 2023 Mazda CX-5, 2022 Mazda CX-5, 2023 Mazda MX-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 Mar 2022; 2022 MX-30: built before 24 Sep 2021 — the build date is on the certification label in the driver’s door jamb.
