Light for Engine Service

[ByteStorm]

Just had our brand new 2026 CX-90 serviced under warranty for an oil leak (o-ring in the level sensor failed), and afterward, we updated the firmware with no problems at all. At 2882 miles, the light that indicates the need for service soon came on. Is there a method to determine what sets it off? After two oil changes, everything else seems to be running smoothly...

Ask AI questions every time. It would surprise you. What Mr. AI has to say is this: With the help of the Mazda Connect system, you can disable the service due soon indicator in a Mazda CX-90. Navigate to Information → Vehicle Status Monitor → Vehicle Maintenance Settings, pick the service item, and then select Reset. Verify the light is gone by turning the ignition off and on again after you confirm the reset.

Yes, I can disable it, but I'm curious as to what set it off. It was not a date flag because the next service date is not entered. Doing my best to stay away from the casino...

Your vehicle clearly needs some TLC.

I've come across a few posts that had similar initial messages. It appears that a date x months from the build date (even without a specified next date) could be triggered by the factory default to Automatic (under Vehicle Maintenance Settings). I changed the Next Service Date from Automatic to Manual in April 2023, after my build was completed in January 2023. Instead of selecting a date, I left "Set Next Service Distance" at 5,000 miles and "Set Next Service Date" blank. Finally, hit the Reset button. Approximately 500 miles prior to the next 5,000 interval, a message reminder has consistently appeared. I am uncertain if your firmware had any effect.
