The owner is eligible for a one‑time replacement of redesigned rear brake pads at no cost if the brake squeal symptom matches a Technical Service Bulletin (TSB) which will be published prior to sending the Second notification. The redesigned brake pads will be covered under the vehicle’s original 3-year/36,000-mile warranty, or 1 year/12,000 miles from installation whichever provides longer coverage.

SummaryCSP14 – 2024-2026 CX-90 Subject: Mazda Rear Brake Pad Customer Service Program Limited Warranty Extension – (CSP14 – CX-90 models) - Phase 1 Mailing – May 2026 In late April we announced two Customer Service Programs (CSP14 & CSP15) where certain vehicles are covered under these two Limited Warranty Extensions, (defined as “Covered Vehicle”); 2024-2026 CX-90 (CSP14) and 2025-2026 CX-70 (CSP15) produced November 18, 2025 and prior. Owner Notification: We are pleased to announce the first phase of Owner Letters will mail on May 29, 2026, to approximately 18,000 owners in campaign CSP14. As stated in our prior communication, we will send subsequent dealer emails with future phased mailings planned throughout Summer 2026. We have also released the Repair Procedure under TSB 04-003/26, the Parts & Warranty information and updated all dealer-facing FAQ documents. ATTENTION ALL DEALERS - Vehicles to be repaired: Due to limited parts supply only the vehicles in this notice can be repaired. To help your Mazda dealer staff identify which vehicles can be repaired we have created an Excel-based VIN look-up tool in Mazda Global Service Support (MGSS) under this campaign. Please enter the VIN in the tool if the customer does not have their parts available letter to confirm the vehicle can be repaired under this CSP. At this time, remaining customers in CSP14 and CSP15 must wait to receive notice that parts are available. Key Benefits of the Customer Service Program-Extended Warranty Coverage for Rear Brake Squeal: Mazda is expanding the standard brake pad coverage from 1-year/12,000 miles to 3-years/36,000 miles to cover repairs related to rear brake squeal. The owner is eligible for a one‑time replacement of redesigned rear brake pads at no cost if the brake squeal symptom matches a Technical Service Bulletin (TSB) which will be published prior to sending the Second notification. The redesigned brake pads will be covered under the vehicle’s original 3-year/36,000-mile warranty, or 1 year/12,000 miles from installation whichever provides longer coverage.
