Service Bulletin/Repair Instructions

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 09-031/25 08/05/25 DESCRIPTION While driving on gravel or dusty roads, dust accumulates at the lower inner edge of the door garnish. When the rear door is opened, the dust may be blown up and enter the cabin, adhering to the seats and the floor. This is caused by a large gap at the lower part of the boundary between the rear door and the front door, and air containing dust and/or sand is sucked up into the gap, accumulating at the lower edge of the rear door garnish while driving. To eliminate this concern, a mass production change is under study. NOTE: In environments where passengers frequently enter and exit the vehicle under dusty conditions (e.g. dirt or gravel roads, off-road driving), a certain amount of dust will enter into the cabin, even in other types of vehicles. Therefore, this phenomenon is not limited to the causes described in this document. Customers having this concern should have their vehicle repaired using the following repair procedure. NOTE: This repair procedure is an interim countermeasure. After a mass production change is implemented, the repair procedure will be updated. Attach the protectors (urethane pads, deflectors and protectors) to both sides of the designated locations according to the following steps.

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.

MT-002/19 09/30/19 and 12/19/19 DESCRIPTION If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage. Clean the intake manifold internally to remove any debris from old engine before installing the new replacement engine assembly. If the intake manifold cannot be properly cleaned internally, replace it.

SA-007/25 10/22/25, 06/02/25 and 02/03/25 DESCRIPTION The Mazda DCA-8000 is required for all warranty battery testing. If the Mazda DCA-8000 is not used, incorrect battery testing may result in unnecessary battery replacement. Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code. NOTE: A Warranty Code is required for warranty claim submission Battery Identification (Mazda batteries have 2 rating types) 1. JIS (Japanese Industrial Standard): JIS codes are six-digit alpha-numeric markings (excluding i-STOP batteries e.g. Q-85, S-95) molded into the top of the battery to identify a battery by the capacity (amps), dimensions, and battery terminal type. Vehicles manufactured in Japan come from the factory with a JIS rated battery. NOTE: Replacement batteries may use a CCA rating. If so, use the CCA rating listed on the battery. 2. CCA (Cold Cranking Amps): CCA ratings are normally located on a sticker affixed to the top of the battery to indicate a battery’s Cold Cranking Amps. CCA rated batteries are supplied with domestically produced vehicles. NOTE: If an incorrect CCA rating is entered into the Mazda DCA-8000, it will result in a false result and invalid Warranty Code from the tester. This will also result in unnecessary replacement of batteries. TEST PROCEDURE 1. Connect the charger clamps to the appropriate battery posts.

Service Bulletin/Repair Instructions

This Service Alert supersedes the previously issued SA(s) and TSB(s) listed below: The changes are noted in Red. SA-035/24 05/31/24 DESCRIPTION There is a concern that some water pumps are being replaced that are not faulty, due to signs of a very small coolant leak from the bleed hole. This Service Alert is to inform you about the water pump sealing mechanism and the criteria if replacement is necessary or not. A mechanical seal (A) is used for the water pump. This mechanical seal can seal coolant (B) by sliding a mating ring (C) against a seal ring (D). When the sliding surface temperature of the mechanical seal is more than 248 °F (120 °C) while driving, a small amount of steam (E) is leaked and bleeds through the bleeding hole (F). After drying, the steam leaves a green coolant deposit near the water pump bleed hole (F). This is a normal condition and does not require water pump replacement. The water pump should only be replaced if there is an accumulation of crystallized coolant near the bleed hole. When you encounter a water pump with coolant seepage marks, decide to replace it or not based on the following criteria using sample photos. NOTE: During the initial period of use*, the sliding surfaces of the seals may not yet be fully settled, which can temporarily increase the amount of leakage. Continued use will allow the surfaces to settle, reducing the leakage. Replacing parts that are already settled with new ones will increase the leakage again until the new parts become conditioned. Therefore, replacement should be avoided in this initial period of use. *As a guideline, this applies to vehicles with less than 1,860 miles (3000 km) of mileage.

The 7G large platform utilizes a new 8-speed automatic transmission. Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running (or “Ready-On” for PHEV). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start and can't move, usually due to a discharged (dead) battery. In the event that a vehicle cannot be started or achieve “ready-on”, wheel dollies must be used to allow the vehicle to be rolled and moved. NOTE: The following procedure is for moving vehicle around the service shop and not for towing purposes. Please reference the owner's manual for towing instructions.

When inspected, the differential or PTO oil is dark or black. This is considered normal and NO repair should be performed. During production, differential ring and pinion gears receive a manganese phosphate coating (commonly referred to as black oxide). This coating forms a porous, oil-retentive surface that improves boundary lubrication and reduces adhesive wear during initial contact cycles. Designed as a sacrificial layer, it is gradually removed under load throughout the break-in process. As a result, after the first few hundred miles, or at the initial gear oil service interval, the lubricant may appear darkened by the worn-off coating. It will contain trace ferrous particles from the normal run-in of the gear teeth and bearing surfaces. This condition is expected and does not, by itself, indicate an issue with the differential or PTO gears.

Noise, Vibration, and Harshness (NVH) Diagnostic Guidelines Diagnostic Guidelines When diagnosing NVH concerns, it is essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure.

This magnifcation of the sun's rays can cause damage to vehicle trim (see examples). Additional information and exemplar images regarding this phenomenon can be found by performing a google search.

Some vehicles may exhibit the following behavior: If the power liftgate (PLG) encounters an obstruction during opening or closing, the jam-safe function is designed to stop the liftgate and reverse it slightly. Normally, pressing the liftgate button (dash, liftgate, or remote) after this happens should cause the liftgate to continue in the reverse direction. Due to a software issue, if the liftgate button is pressed after the jam-safe function is activated, the liftgate may instead continue moving in the direction of the obstruction. This occurs randomly and cannot be predicted. To correct this concern, the control software of the power liftgate control module has been modified to ensure the liftgate always continues in the reverse direction when the opener switch is operated immediately after the jam-safe function is activated.

Important Note: This Service alert is intended as an early notification for upcoming software releases. Please refer to the latest dealer communications and MGSS for updated information. CX-90 MHEV Battery: Mazda is currently experiencing many backorders on MHEV Batteries (K6Y8-67-ZBXD). The issue causing most of the concerns is a cell imbalance inside the MHEV battery, which sets DTC P0DAB. The repair solution for this concern is to perform the software reflash and replace the battery as required. The cell balancing issue is resolved with a software reflash starting in November of 2023 production and this software update is part of recall 7024J - SAFETY RECALL - MULTIPLE ECU'S REPROGRAMMING. Ensure this recall is completed on every CX-90 that comes into your dealer to prevent possible MHEV cell imbalance. As a reminder, the MHEV battery is warrantied 8 years/80,000 miles to support our customers through the life of their vehicle. In terms of the MHEV Battery back-order status, as a result of significant efforts, including air-shipping hundreds of replacement batteries, we are projecting all current backorders will be filled by the last week of March 2025. CX-90 and CX-70 PHEV Electrical Leakage: Some customers have experienced an “electrical leakage fault” with DTC P0AA6 resulting in a no start condition after one key-cycle. Mazda has identified a PCM software programming issue that causes this DTC occurrence. Under current PCM logic, when P0AA6 detection occurs, the vehicle is prevented from restarting. The new software will be available in late March to reflash vehicles. This allows vehicles to be restarted if the fault is detected. Should the DTC persist, perform normal MGSS service procedures for electrical leakage diagnosis.
