- [01\-010\-26](/bulletins/11036688.md), 2026-09-02, Service bulletin: ENGINE. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted in Red text. 01\-012/22 10/06/22 DESCRIPTION Some vehicles may exhibit accumulation of dried coolant \(1\) around the water pipe \(2\). This is caused by a gap between the housing and pipe due to a press fitting during the manufacturing process. The accumulated coolant is solidified and plugs the gap in high temperature environment and the seepage is stopped and does not progress. This is normal and does not require a part replacement, clean off the dried coolant from around the pipe with a wire brush. REPAIR PROCEDURE 1. Verify the customer concern. 2. If the above condition is experienced, remove the accumulated coolant around the pipe \(1\) with a wire brush etc. NOTE: Perform the procedure on the vehicle. No need to remove the water pipe and hoses.
- [SA\-041\-26](/bulletins/11034447.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM; ENGINE. 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.
- [SA\-029\-26](/bulletins/11032103.md), 2026-05-05, Service bulletin: UNKNOWN OR OTHER; ENGINE; POWER TRAIN; SERVICE BRAKES. This Service Alert supersedes the previously issued SA listed below: The changes are noted in Red. SA\-011/24 02/12/24, 06/06/24, 07/29/24 DESCRIPTION Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle\-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers. SCHEDULED MAINTENANCE Refer to the applicable Workshop Manual or Owner's Manual for vehicle \-specific manufacturer scheduled maintenance. Workshop Manual \- Refer to section 00\-00 SCHEDULED MAINTENANCE. Owner's Manual \- Refer to section 8 Maintenance and Care. b. Note: Please refer to the information below outlining the services not included in Mazda's Factory Scheduled Maintenance: IMPORTANT: Recommending fluid flushes when not necessary can lead to customer confusion and dissatisfaction. Fluid flushing for preventive maintenance purposes is strongly discouraged, unless otherwise specified in a published procedure \(Owner’s Manual, Workshop Manual, Technical Service Bulletin, etc.\).
- [SA\-026\-26](/bulletins/11032101.md), 2026-05-05, Service bulletin: ENGINE. This Service Alert supersedes the previously issued M\-Tip\(s\) listed below. The changes are noted in Red text. 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\-052\-25](/bulletins/11026351.md), 2025-12-05, Service bulletin: ENGINE; POWER TRAIN. Some customer's might state that they notice fluid or oil leaking/dripping on the ground when the vehicle is parked. For this concern, inspect the vehicle for any trace of a fluid or oil leak and use the following examples as a guide to determine if it is severe enough to require a repair, or just to clean the area and monitor it at the next service. Examples of residue or seepage that may not be considered a leak and that may not require repair based on splash shield inspection.
