PF-24-01R22024-11-04. Other. POWER TRAIN. This Parts Flash replaces Parts Flash 24-01R1 dated September 19, 2024. Due to a manufacturing change, the CX-70 and CX-90 transmission has undergone a transmission part design change when replacing the transmission assembly. The new/superseded design can be used in place of the old/original design as the coolant hose (D-Code 21-5LX) is no longer needed to be used. Transmission part numbers beginning with supersession level “A” have had this change.
SA-031-24a2024-11-04. 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. For new vehicles in stock at the dealer, inspect and maintain the batteries periodically according to the repair procedure.
SA-078-242024-11-04. Service bulletin. POWER TRAIN. Some vehicles may experience a transmission warning light on or flashing in the instrument cluster with no DTCs after a full transmission replacement. This will affect the configuration or learning with MDARS.
SA-076-242024-11-04. Service bulletin. ELECTRICAL SYSTEM. This Service Alert provides information for the following symptoms. Although Battery State of Charge (SOC) is full, Maximum Driving Distance Display shows 1 mile (1 km). • Although Battery SOC is full, the vehicle cannot drive using EV mode (using electric motor power only) and will use HEV mode (using both electric power and a gas engine. • This is caused by low ambient temperature and low battery temperature. EV mode is suspended until the battery warms up to protect it from degradation and the gas engine will power the vehicle. This is normal operation. If the battery pack is able to warm up, EV mode will start and the display will change to show the correct Maximum Driving Distance Display for EV mode.
SA-074-242024-11-04. Service bulletin. POWER TRAIN. Some customers may experience a grunt or grind noise when the transmission shifts from 1st gear to 2nd gear. The grunt-type noise is produced during the 2nd gear engagement. This issue will not affect the driveability or reliability of the vehicle. The vehicle is safe to drive. It is OK to release the vehicle back to the customer.
SA-069-242024-11-04. Service bulletin. STRUCTURE:BODY. Some vehicles may exhibit poor hands-free liftgate operation after a Mazda genuine trailer tow hitch accessory installation. IMPORTANT: When a Mazda genuine trailer tow hitch is installed on a CX-90 equipped with hands-free liftgate function, the sensing area is reduced due to the mechanical structure of the hitch. The hands-free liftgate’s optimal sensing area below the rear bumper is shown in green boxes in the image below. Since the left side of the hitch has a 7-pin connector socket, the right side is the most ideal for hands-free operation. For safety, be extra careful performing the kicking motion around the hitch.
SA-040-24a2024-11-04. Service bulletin. ENGINE; ELECTRICAL SYSTEM. Some customer may experience any of the following: Multiple Warning Lights On • Infotainment center display blank • Engine no start unless the key transmitter is placed near the start button • Interior lights do not illuminate • DTC P2507:00 - PCM, PCM POWER SYSTEM: (LOW INPUT) stored. • DTC U0156:00 - PCM, CAN communication system, Communication error with CMU (Connectivity Master Unit). • This may be caused by Fuse F1 not fully seated (poor terminal tension) or a poor ground connection at the front harness connector G03.
