Service bulletins for the 2022 Mazda MX-5
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| SA-041-26a | 2026-10-03. Service bulletin. ELECTRICAL SYSTEM. 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 |

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-027-26a | 2026-07-03. Service bulletin. ELECTRICAL SYSTEM. This SA supersedes the previously issued bulletin(s) listed below. The changes are noted below in Red. SA-027/26 04/16/26 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. REPAIR PROCEDURE 1. Perform appropriate repair to vehicle. If needed, use the Battery Diagnostics of the DCA-8000 to test the charging and starting systems by following the on-screen instructions for entering the appropriate information. Refer to the Mazda DCA-8000 Instruction Manual for more information. |
| SA-027-26 | 2026-05-05. Service bulletin. ELECTRICAL SYSTEM. This SA supersedes the previously issued bulletin(s) listed below. The changes are noted below in Red. 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.

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. |
| 09-007-26 | 2026-02-03. Service bulletin. STRUCTURE:BODY; ELECTRICAL SYSTEM. Some vehicles may exhibit the power window(s) not working properly (window does not move or has fallen into the door) and/or making an abnormal noise while operating the power window switch. This may be caused by the cable of the power window motor being damaged from water entry through area (1) of the front beltline molding. Convertible Top: To eliminate this concern, the shape of the door glass has been modified during mass production to prevent water entry to the power window regulator. Retractable Hardtop: No mass production change is scheduled. |
| 09-005-26 | 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. |

| 09-038-24 | 2024-09-04. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer. NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealer’s responsibility to comply with Federal, State, and local laws concerning odometer and related documentation requirements when providing a repair or replacement. Mazda vehicles are manufactured with tamper-proof speedometers. When a speedometer is replaced, the new speedometer will read zero (0) miles. This procedure is extremely important to accurately represent actual vehicle mileage. Prior to speedometer removal, complete the information required on the “Speedometer Replacement Label”. Labels can only be ordered through Mazda eStore. In an effort to achieve a higher level of Customer Experience and retain the value of Mazda’s vehicles, MNAO Warranty Operations is allowing all Mazda dealers to utilize a third party, SPECMO Enterprises, Inc., for Instrument Panel Cluster (IPC) odometer setting service. With the use of SPECMO’s services, it is possible that the odometer will be set between 10 to 31 miles over the odometer mileage at the time of replacement for both warranty and customer pay repairs. Please make sure that the customer is aware that there may be a slight variance to the odometer, in which case the customer may have to accept the slightly higher mileage. Since odometer setting service is not part of the warranty repair, it is not warrantable nor required, but optional. However, Mazda Warranty policy provides after- warranty assistance (AWA) or DSA that can be utilized to cover this service expense. |
