16-003-232023-06-04. Service bulletin. EQUIPMENT:ELECTRICAL:INFOTAINMENT; ELECTRICAL SYSTEM. Some customers may complain that Mazda Connect does not start (blank screen) or that it takes a long time to restart/ reboot after starting the vehicle. This is caused by the initialization process with the CMU failing at startup due to a defective circuit board element. To eliminate this concern, the internal hardware (DRAM) of the CMU has been improved.
01-007-232023-06-04. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. 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.
SA-018-23a2023-05-05. Service bulletin. ELECTRICAL SYSTEM. This service information provides testing and charging procedures in order to promote proper battery maintenance, to deliver new vehicles with fully charged batteries, and to reduce unnecessary battery replacement cost.

Some customers may experience one or more electrical malfunctions after a vehicle body repair. The newly painted fender stay (2) may be causing a poor front harness (1) ground connection.
SA-009-232023-03-03. Service bulletin. EQUIPMENT:ELECTRICAL:INFOTAINMENT; EXTERIOR LIGHTING; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Some customers may complain about any of the following: Infotainment Center Display does not provide the Authorization Code during the MyMazda App Connected Vehicle enrollment. Remote function(s) inoperative. Engine Start / Stop, Door Lock / Unlock, Lights ON / OFF MAZDA CONNECT connected vehicle reception strength icon shows "X" or " ".
07-002-232023-03-03. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may complain that the ambient temperature on the instrument cluster is displayed more than 50 °F (10°C) lower than the actual temperature, resulting in insufficient performance of the air conditioning. This is caused by inappropriate soldering in the ambient temperature sensor. To eliminate this concern, the soldering process has been enhanced since December 2021 at the supplier.
09-001-232023-02-02. Service bulletin. ELECTRICAL SYSTEM. Some vehicles may exhibit DTC U3000:04 (Telematics communication unit internal malfunction) stored after the connected service contract has been discontinued (only vehicles in which the customer opted out of CV services are affected - CSP04). This is caused by improper control software of telematics communication unit. To eliminate this concern, the control software of telematics communication unit has been modified.
SA-006/232023-02-02. Service bulletin. ELECTRICAL SYSTEM. Some customers may complain about the infotainment system and/or the MyMazda App showing incorrect clock and/or tire pressures and/or tire pressure missing. This may be caused by: - Incorrect calendar entry (month/day/year) after a battery disconnect - Infotainment system software update. - BCM TPMS unlearn during vehicle storage or transport. - Wheel/Tire change
SA-005/222023-02-02. Service bulletin. ELECTRICAL SYSTEM. Customers having MAZDA CONNECT concerns should have their vehicle repaired using the following repair procedure.
RF-23-022023-02-02. Service bulletin. ELECTRICAL SYSTEM. Due to the supply chain shortages for BDGF-66-5G0G, hardware has been confirmed compatible between BDGF-66-5G0B up to the G suffix. This can be used for repair with vehicles originally equipped with C to G level suffix parts.
07-004-22b2023-01-05. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some customers may complain the A/C blows warm. This may be caused by one of two things. Cause 1: After accelerating in hot weather, the A/C blows warm air for a longer time than other models. This is caused by improper control software of the PCM not allowing the A/C compressor to resume properly after acceleration. During a hard acceleration above a certain throttle level opening, the PCM stops the A/C compressor operation for better acceleration. It then resumes the compressor operation after the acceleration. To eliminate this concern, the control software of the PCM has been modified. Cause 2: Insufficient cooling performance at ambient temperature of around 68 °F (20 °C) in daytime. This is caused when both the ambient temperature and the cabin temperature are at around 20 °C (68 °F), auto A/C set at around 20 °C (68 °F) may not cool down the cabin temperature properly. To eliminate this concern, control software of the dash-electrical supply unit (Dash-ESU) has been modified.
