  Summary

  Due to a manufacturing change, the CX-70/CX-90 transmission has undergone a transmission part design change when replacing the transmission assembly. Old design originally required a coolant line running to the top of the bell housing, the new design has omitted the hole and need for the coolant line. The new/superseded design can be used in place of the old/original design and the coolant hose is no longer needed to be used.

  Summary

  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.

  Summary

  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.

  Summary

  Some vehicles may exhibit a rattle noise from the rear end of the rear glass panel on the panorama sunroof. This may be caused by body vibration while driving and slight gaps (1) between the fastener mounting to the headliner and the sunroof frame. To eliminate this concern, the fastener has been modified to restrain the rattling. NOTE: For 2024 CX-90 with a rattle noise in the center of the sunroof (the front glass panel), see TSB 09-010/24 - RATTLE NOISE FROM CENTER OF PANORAMA SUNROOF.

  Summary

  Some vehicles may exhibit different air temperature coming from the center ventilation grille on the left and right. This is caused by the mixing control of hot and cold air not being correct.

  Summary

  The right-side hood strut features a two-step mechanism for opening and closing. The first step is for general, the second step is for “service mode”. When you open the hood, after completing the hood in service mode, the stay damper might rattle because it loses internal pressure support to the hoodfender- strut system. This is normal operation and not a sign of any malfunction, no parts should be replaced.

  Summary

  Some customers may complain about a low washer fluid level warning message even though a visual inspection of the washer fluid tank looks like it still has a fair amount of fluid in it. With the CX-90 and CX-70 introduction of the front-engine and rear-wheel-drive layout, the washer tank shape was changed from a vertical to a horizontal type. This makes it look like there is still enough liquid left if viewed from the spout when the warning light comes on.

  Summary

  After an HV inverter replacement, there is no instruction in the WSM to perform Initial Learning of the Electric Motor Speed Sensor. This is required after replacing the inverter or electric motor. As a result, when attempting to start the vehicle, the Internal combustion (ICE) engine will start and then stop with DTC P0C17 stored. If this DTC is set, refer to P0C17:00 [SGC2/DMCM (e-SKYACTIV PHEV)] in the troubleshooting manual. NOTE: When attempting to complete the Learn of Electric Motor Speed Sensor with MDARS, it will be unsuccessful until the vehicle is shut off and left undisturbed for 1-2 hours. Make sure the 12V battery is fully charged and the EV battery is charged, then connect the battery and wait a minimum of 1-2 hrs with the ignition OFF before proceeding directly to the relearn procedure. DO NOT start the engine until directed to do so in the relearn procedure.
