Service bulletins for the 2026 Mazda CX-70

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

CSP15 Owner Ltr2026-05-04. SERVICE BRAKES. 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. 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 repairs to rear brake components caused by rear brake squeal before your vehicle reached 3 years or 36,000 miles from the vehicle’s in-service date (meaning, the start date of the warranty for the vehicle), whichever is earlier (“Eligible Costs”) subject to the following limitations as described in this letter. Repairs completed at a non-Mazda facility after April 2026 as printed in this Owner Letter are not eligible for reimbursement.

09-027-262026-10-01. Service bulletin. ENGINE; ELECTRICAL SYSTEM. DESCRIPTION Some CX-70 and CX-90 PHEV vehicles may fail to start (enter READY mode) in cold weather, but the vehicle can often be started successfully on the next attempt. This may occur when leakage current between connector terminals causes the MAIN Relay to be falsely detected as ON. As a result, the Battery ECU may incorrectly determine the relay status, preventing READY mode activation and resulting in a no-start condition. One or more of the following DTCs may be stored: P0AB9, U0100, U0110, and U0115 and multiple warning lights may also turn on. This is caused by corrosion of the connector terminals on the 3002-411 connector in the luggage compartment from water. To eliminate this concern, urethane has been added around the connector to help prevent water from reaching the connector terminals. REPAIR PROCEDURE 1. Verify the customer concern. 2. Diagnose and repair the vehicle according to the following steps. NOTE: The following procedure uses a heat shrink tube with solder. (1) Connect wire to wire with heat shrink tube. (2) Form a loop at the end of wire to create a passage for the other wire.
