- [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.
- [09\-019\-26](/bulletins/11034436.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER; ENGINE. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted in Red. 09\-012/21 12/13/21, 06/10/21 and 04/27/21 DESCRIPTION Some customers may experience all of following symptoms: The door lock/unlock operation will not work using the remote transmitter button. 1. The door lock/unlock operation will not work using the door lock/release touch sensor. 2. The engine will not start using the ignition switch. 3. The transmitter operates by itself. 4. The key battery drains faster than usual. 5. Symptoms 1\-3: This may be caused when excess load is applied to the remote transmitter, deforming the electrical terminals and creating poor contact with the battery. To eliminate this concern, the structure in the remote transmitter has been modified to reduce the deformation of the electrical terminals. Symptom 4\-5: This may be caused when excessive load is applied to the remote transmitter, creating a gap around the gasket where moisture enters and corrodes the circuit board which in turn drains the key battery faster than usual. To eliminate this concern, the thickness of the case wall on the gasket mounting surface has been increased and the bonding strength of the components has been improved to prevent deformation. REPAIR PROCEDURE • If the battery is bad or installed incorrectly, replace the battery and/or install it correctly. • If the remote power saving function is off and the battery is good and installed correctly, replace the defective remote transmitter with a modified one according to the instructions on MGSS \(IMMOBILIZER SYSTEM\-RELATED PARTS PROGRAMMING\). NOTE: DO NOT replace other remote transmitter\(s\) for the vehicle if they not experiencing an issue.

- [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\-014\-26](/bulletins/11030636.md), 2026-04-02, Service bulletin: ENGINE. 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.

- [01\-004\-26](/bulletins/11029240.md), 2026-03-03, Service bulletin: ENGINE. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted below in Red. 01\-007/24 06/20/24 ENGINE OIL LEVEL WARNING LIGHT ON WITH DTC P250F:00 DUE TO LOW ENGINE OIL LEVEL \(UPDATED WITH SSPD5 INFORMATION\). All Mazda Dealers: Follow the Special Service Program SSPD5 – Valve Stem Seal Class Action for determination if valve stem seals should be replaced. 1. Verify the customer concern following the Special Service Program SSPD5 Repair Procedure. As the repair procedure states in SSPD5, confirm the engine oil is not leaking from the engine. If the customer reports engine oil is low upon arrival at a dealer, replace the valve stem seals following the flow chart for SSPD5. If engine oil is low upon arrival with no customer complaint, check for SSPD5 and if the valve stem seals have not been replaced under prior Warranty, replace the seals. If the valve stem seals have been replaced under a prior Warranty claim, contact Hotline for further instructions. If valve stem seals need to be replaced, replace the valve seals of the exhaust side with improved ones using the special tools called out in the repair procedures below. 2. Top off the engine oil \(if needed\). NOTE: Engine oil should not be topped off without replacement of the valve stem seals. 3. Verify the repair. NOTE: If unsure what steps to take during a customer visit for oil consumption related to SSPD5, fill out Dealer Recall Help on OneMazda.
