Summary
Subject: Announcement of Special Service Program (SSPE2) Ethernet Communication – Over The Air (OTA) Update Concerns and Manufacturer Service Program (MSP67 ) – Battery Depletion - 2026MY CX-5 vehicles URGENT - STOP DELIVERY OF AFFECTED VEHICLES: MAZDA SALES AND SERVICE TEAMS - ACTION ITEM: Between both campaigns there are approximately 27,565 vehicles (for both campaigns) in stock at U.S. Mazda dealers. All Mazda dealers must quarantine any affected New, Used or Certified Pre-Owned in-stock vehicles until the repair is completed. The affected dealer inventory list will be available to each District Service Manager with the notification of this dealer email. Once completed, the vehicle can be delivered, and the Warranty claim can be submitted later without penalty since the vehicle has been repaired. Mazda Motor Corporation has decided to conduct two service programs Special Service Program (SSP) and Manufacturer Service Program (MSP) on certain 2026MY CX -5 vehicles sold in the U.S. and U.S. Territories. Vehicles also produced by Mazda Motor de Mexico (MMdM) and Mazda Canada Inc. (MCI) are affected and should be repaired if presented to your dealership. Please see the description, model, model year, and VIN ranges below for all vehicles in these two campaigns. There are 70,225 vehicles affected by SSPE2 and 53,653 vehicles affected by MSP67. All vehicles in MSP67 are also affected by campaign SSPE2. Please read this complete letter for all the repair information . Special Service Program SSPE2 – Ethernet Communication and OTA Update Concerns - SSPE2 addresses two concerns: 1) Ethernet communication (CDC -DCM communication) concern: Communication in the Cockpit Domain Controller (CDC) and Data Communication Module (DCM), may be interrupted, making the connected services unavailable. The interruption may cause the master warning light to illuminate and audible warning from the emergency call speaker. 2) OTA software update concern: Due to an improper communication control program in the CDC and DCM, may prevent OTA software updates to be completed. In addition, if an OTA software update is successfully completed, the vehicle's software configuration status may not be correctly transmitted to the server, which may prevent notification of subsequent software update successfully completed OTA software updates may not properly sync with Mazda’s servers potentially preventing future OTA updates. Repair Outline: Reprogram the DCM and CDC software, using a USB memory stick with modified software. Manufacturer Service Program MSP67 - Battery Depletion Concern - MSP67 addresses two concerns: On certain subject CX-5 vehicles, the vehicle may fail to start due to battery depletion after IG OFF. 1) Data Communication Module (DCM): Remote Diagnostics software may reset and fail to close a CAN communication channel after ignition OFF and the battery may drain over time. Note: Vehicles for Puerto Rico and Mexico markets are not affected by this factor as they are not equipped with the DCM. 2) Body Control Module (BCM): The Body Control Module (BCM) may intermittently reset during sleep mode operation. Vehicles may cycle between wake-up and sleep states, leading to battery depletion. Repair Outline: Reprogram the BCM software with M-MDS, using Mazda Diagnostic and Repair Software II (MDARS II). The DCM software is being re-programed by SSPE2. Note: When the BCM is reprogrammed, the Central Gateway (CGW) will also be updated automatically.

Summary
COMPLIANCE WITH NEW YORK STATE GENERAL BUSINESS LAW §399‑CCCCC (CONNECTED VEHICLE SERVICE; DOMESTIC VIOLENCE VICTIMS) DESCRIPTION This Service Information is issued in accordance with New York State General Business Law §399􀀀CCCCC (Connected Vehicle Service; Domestic Violence Victims). This regulation is intended to protect victims of domestic violence by allowing them to request the termination of third-party access (including access by an alleged abuser) to connected vehicle services, such as vehicle location tracking and remote control functions. To support this requirement, this Service Information enables confirmation of whether a vehicle is subject to connected vehicle services by referring to the SUBJECT VIN & PRODUCTION DATE RANGE, and provides guidance on the procedure to terminate such services when a customer requests the removal of third-party access for an applicable vehicle. Effective July 1, 2026, if a customer requests action under this regulation, a CMU/CDC software update must be performed to enable appropriate control of connected vehicle service access. If no request is made by the customer, the CMU/CDC software update is not required. REPAIR PROCEDURE 1. Confirm that the customer has requested deactivation of connected services in accordance with New York State General Business Law related action. 2. Perform the CMU/CDC software update according to the procedures outlined in the appropriate TSB shown in the table below:

Summary
DESCRIPTION Some vehicles may exhibit a discharged 12V battery when attempting to start the engine. This concern is due to improper control of the Body Control Module (BCM) and Central Gateway (CGW) software, causing the vehicle to repeatedly cycle between wake-up and sleep states, eventually resulting in a discharged battery. To eliminate this concern, the BCM and CGW control software have been modified. REPAIR PROCEDURE 3. Reprogram the BCM and CGW with the Mazda Modular Diagnostic System (M-MDS), using Mazda Diagnostic and Repair Software (MDARS II): MDARS II ECU Reprogramming Procedure.

Summary
This SA supersedes the previously issued SA(s) listed below. The changes are noted in Red. SA-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.
