Mazda warranty extension CSP14

What it saysDear 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. NHTSA’s full summary ↓

Mazda filed this with NHTSA as a warranty extension dated Sep 24, 2026, received May 4, 2026, about the service brakes — 25 documents under this number: CSP14 Repair d, CSP14 Parts_Warr e, CSP14 Owner Ltr g, CSP14 Owner Ltr f and 21 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.

What 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.

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. Warranty Coverage Expansion Mazda is expanding the scope of coverage under the standard 3 years/36,000 miles, whichever comes first, warranty to provide necessary repairs at no cost to you if your Covered Vehicle experiences rear brake squeal. 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 TSB is scheduled to be released when the parts are expected to be available. The newly installed redesigned brake pads will be covered for rear brake squeal under your Covered Vehicle’s original limited warranty of 3 years/36,000 miles, or for 1 year/12,000 miles from the installation of the redesigned brake pad, whichever is later. If your Covered Vehicle is currently experiencing rear brake squeal and is more than 3 years old or exceeds 36,000 miles, whichever comes first, you will receive three (3) months, after the Part Available Notice Letter has been sent, to receive the redesigned brake pad under the terms of this notice. Repairs under this warranty extension during the coverage period must be completed at a Mazda dealer. Reimbursement Mazda is offering reimbursement to owners and lessees of a Covered Vehicle who previously incurred out-of-pocket expenses for inspections and r

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 database

Owners of the 5 model years this bulletin names have filed 587 complaints with NHTSA since 2015. 9 of them name Service Brakes — 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.

Vehicle has been squealing countlessly when braking about 1 to 2 days after leaving the dealership in September 2024 up until current. The vehicle has been out of commission for more than 15 days while attempts to repair the issue at local Mazda dealerships.

The brakes make noise. I asked Mazda if there were any recall. The service person replied there is on the brakes but they were doing it in groups and it was not my group yet

2025 Mazda CX-90 · Service Brakes · filed with NHTSA Sep 13, 2026 · ODI 11763883

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 579.5

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. The document itself sets the build window: 2024-2026 Mazda CX-90: built before 19 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
