This worked like a dream. I had the same issue, I've followed the instructions and the warning has gone away. Many thanks

 

Frankly - even on my 22 or 24 the oil change / maint reset are confounding - its useless for me as i would do it every 2500-3k from a pad i write it on - - I also re-read the manual at each interval - i suppose im stuck in prehistoric ways -Its got a stupid default and i switched to manual 3k milez - just hit reset to shut it up - but at 2400 miles it starts warning me - pisser tech

 

Keeping a notebook is actually a good idea. This way you have a paper record and also should you ever sell your vehcle tit is selling tool to physically show what you did.
I keep one on most all vehicles I have owned since the mid 80's. But not all of them.

My Mazda note books for it started the very month of purchase and I have logged everything with few exceptions. like the stereo upgrade. LOL

 

This warning popped up on our cx5 today...2024 cx5 2.5L NA with about 14000km. We had an oil change 3 months ago and about 4000km ago. Tried to do the regular clearing in the info system and didn't work (I only have the option of resetting vehicle maintenance, on my info screen but not the oil or tires) I just tried the procedure described by the quoted post.. The system warning light blinks, and the engine oil due message disappears, but comes back the next time I turn the engine on.
Any suggestions?
Thanks

 

All members reading . please when asking service advise please at least include basic info on your Mazda

Minimum is :

Year
Miles
Engine size

 

Sorry.. Updated my post to include that

 

If you followed your owners manual information on how to set the service information correctly...
Then because ....
A 2024 with your miles is still under WARRANTY. The BCB controls that area of the monitoring information and as such you should go to Mazda and not continue to attempt to re-set or clear the service settings. Doing so may damage your BCM and void an important part of your newer Mazda's system
Mazda will either show you how to do it. Find a problem with your BCM and it will be replaced under warranty. Or they may do an ECU "flash" to the most resent update program or the original ECU program.
