Mazda warranty extension CSP14

Mazda filed this with NHTSA as a warranty extension dated Aug 25, 2026, received May 4, 2026, about the service brakes — 20 documents under this number: CSP14 Repair c, CSP14 Parts_Warr d, CSP14 Owner Ltr e, CSP14 Owner Ltr d and more. It names 5 model years (2024–2026). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

Dear Mazda Owner: You are receiving this notice because Mazda’s records indicate that you have a 2024-2026 Mazda CX-90 vehicle manufactured before November 19, 2025. Mazda Motor Corporation has decided to conduct a Customer Service Program CSP (14) to inform you that Mazda is expanding the scope of coverage under the New Vehicle Limited Warranty to provide necessary repairs free of charge if your Covered Vehicle has experienced rear brake squeal and to inform you that you may be eligible to receive reimbursement for past out-of-pocket expenses you previously incurred for repairs on the terms and conditions as described below. Repair parts are not currently available. It is expected that parts will become available in May 2026. Another letter will be sent to you once parts are available to repair your vehicle with instructions for making an appointment at your nearest Mazda dealer.

If your Covered Vehicle is currently experiencing rear brake squeal, you will be eligible for a one-time rear brake pads replacement with Mazda’s redesigned brake pads. A dealer must inspect and confirm your Covered Vehicle is experiencing rear brake squeal matching Technical Service Bulletin (“TSB�) 04-003/26 for you to receive the repairs at no cost to you.

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 579.5

Is Mazda CSP14 a recall?

No. A warranty extension 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 CSP14 repair free?

A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does CSP14 cover?

The manufacturer filed it against 5 model years: 2026 Mazda CX-70, 2025 Mazda CX-70, 2026 Mazda CX-90, 2025 Mazda CX-90, 2024 Mazda CX-90. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
