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.

- [09\-005\-26](/bulletins/11028099.md), 2026-02-03, Service bulletin: LANE DEPARTURE: BLIND SPOT DETECTION; ELECTRICAL SYSTEM. If the right\-side Blind Spot Monitoring \(BSM\) control module is replaced for any reason, it is also necessary to replace the left\-side BSM control module in order to complete the radar aiming procedure. If the right\-side BSM control module is replaced alone, "Automatic Configuration" and "BSM Radar Aiming" cannot be completed due to a programming error in the module. In most cases, if the left\-side BSM control module is replaced alone, "Automatic Configuration" and "BSM Radar Aiming" can be completed without any problem \(See CAUTION below for more details\). Other possible symptoms that may be found if the right\-side BSM module is replaced alone: BSM aiming fails “BSM OFF" indicator ON Center Display warning message BSM failsafe \(No operation\) DTC U3000:54 stored in memory DTC U1A4B:54 stored in memory \(CX\-3, MX\-5 only\) NOTE: Since a new BSM control module does not retain the vehicle specification information, it is necessary to acquire and store the vehicle specification information transmitted via CAN communication from the combination meter through automatic configuration after replacement.
- [SA\-055\-25](/bulletins/11026353.md), 2025-12-05, Service bulletin: SERVICE BRAKES. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging.

This concern may be caused by the anti\-fog coating not preventing inner condensation under certain situations. To eliminate this concern, the anti\-fog coating performance was improved.
- [SA\-016\-24c](/bulletins/11009644.md), 2024-11-04, Service bulletin: SERVICE BRAKES. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging.

- [09\-041\-24](/bulletins/11006899.md), 2024-09-04, Service bulletin: EXTERIOR LIGHTING. Some customers may notice water entry into the front combination lights \(as shown below\). This is due to poor sealing where rain or other water can enter inside the light. To eliminate this concern, the shape of the front combination light has been changed to improve sealing ability.
- [04\-003\-24](/bulletins/11005528.md), 2024-08-02, Service bulletin: SERVICE BRAKES. Front Brake Noise Symptom 1: Some vehicles may exhibit a click noise when first moving forward or reverse from a stop OR when first applying the brakes while moving forward at slow speeds. This is caused by deteriorated grease between the brake pads and the shim, the front brake pads move upward/downward along with the brake rotors during brake application. When the vehicle moves or the brakes are applied the next time, the front brake pads move to the other side, which causes a click noise. Front Brake Noise Symptom 2: Some vehicles may exhibit the brakes having an unusual noise or vibration when applying the brake. This is caused by rust on the brake disk plate’s surface. Rear Brake Noise Symptom 1: Some vehicles may exhibit a squeak noise from the rear brakes while braking lightly and occurs more frequently when driving at slow speeds. The noise is caused by poor contact between the guide plate and the mounting support. To eliminate this concern, the material of the pads has been changed to copper\-free and the specification of the shims has been changed to a coated spring with tape. Rear Brake Noise Symptom 2: Some vehicles equipped with an electric parking brake \(EPB\) may exhibit a grinding noise from the rear brakes when braking. This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.
- [SA\-016\-24a](/bulletins/11003396.md), 2024-07-05, Other: SERVICE BRAKES. Some vehicles exhibit brake related concerns such as brake noise, brake judder or brake dragging. If you encounter a customer complaint for any one of these symptoms, refer to the following information to understand why symptoms may occur, and to better assist the customer in resolving their specific brake concern.
