You are receiving this notice because Mazda’s records indicate that you have a 2025-2026 Mazda CX-70 vehicle manufactured before November 19, 2025. Mazda Motor Corporation has decided to conduct a Customer Service Program CSP (15) 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.

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 repairs to rear bra

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda CSP15 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 CSP15 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 CSP15 cover?
The manufacturer filed it against 2 model years: 2026 Mazda CX-70, 2025 Mazda CX-70. 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: 2025-2026 Mazda CX-70: built before 19 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
