Mazda bulletin 04-003-25a
What it saysSome vehicles may experience premature wear of the front inner brake pads. NHTSA’s full summary ↓
Mazda filed this with NHTSA as a service bulletin dated Dec 24, 2025, received Jan 3, 2026, about the service brakes. It names 2 model years (2022–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome vehicles may experience premature wear of the front inner brake pads. The pads wear down by about 0.1 in (3 mm) every 6200 miles (10,000 km), and may require replacement at less than 12,400 miles (20,000 km). This is caused by intrusion of dirt and sand into the gap between the pad and the rotor. To eliminate this concern, the shape of the dust cover has been changed, and the brake pad chamfer shape has been revised.

Read by machine from the document NHTSA serves (2 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 04-003-25a 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 04-003-25a 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 04-003-25a cover?
The manufacturer filed it against 2 model years: 2023 Mazda MX-30, 2022 Mazda MX-30. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
