What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 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 and the fan motor bearing may become worn out during use. To eliminate this concern, the fan motor 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 (9 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 24 model years this bulletin names have filed 1,061 complaints with NHTSA since 2015. 33 of them name 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 has a recurrent malfunction of the Adaptive Front-lighting System (AFS), part of the exterior headlight system and advertised as a safety feature within Mazda’s i-ACTIVSENSE® technology. The failure presents as a dashboard warning stating: “Headlight System Malfunction.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 09-029-25 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 09-029-25 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 09-029-25 cover?
The manufacturer filed it against 24 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.
