I got my CX-30 two days ago and while playing around with infotainment system notice that tires pressure monitoring displays 50 psi on each wheels. Then I lowered pressure to 36 psi as it should be and expected that tires pressure monitoring system showing up new data, but for some reasons it just didn’t happens. It continues display 50 psi. Any thoughts? Do I have to reset monitoring system in some way?

Finally, looks like I resolve the issue. Tyre Pressure Monitoring has been start display updates information after I initialize SOS button ¯\(ツ)/¯ Don’t ask how TPMS relates to SOS button. It looking strange for me, but it helps.

If someone has same issue or annoyed by blinking SOS button, here is good howto video I found

I am having this same problem with the TPMS but my CX-30 does not come with an SOS button. Is there some other way to reset the car software such that it will begin updating tire pressure? I hesitate to disconnect and then reconnect the battery or reset factory defaults from the infotainment unit. And I'd like to avoid the hassle of taking it in to a dealer. There has to be another way to software this on my car as well. My car too, shows 50 psi in each time, last updated 6 months ago.

My TPMS shows I was low the other day. I filled to 36 and drove to work. It reset itself, I didn't have to do anything

My 2021 is doing the same thing, shows 50 PSI for the four tires and states it was last updated on 1/13/2021. I verified all tires have correct pressure and have driven it 45 miles since verifying air pressure and it still shosw 50 PSI in the Infortainment display.

Check the calendar entry in Mazda Connect, if it's incorrect it might cause this issue:
I’ve had this happen after my last two visits to my Mazda dealer for service. In both cases the date listed with the tire pressure readings was for about 12 hours in the future after the visit (I know the battery was connected on the second visit). Once the real current date and time was past the displayed last tire pressure date and time, the readings started to display correctly. Thanks for the bulletin as now I can correct it immediately, following the procedure.

I know this is an older thread, but I just wanted to chime in with a confirmation that the instructions in the service bulletin totally worked for me. So, thank you, Hawke, for posting that bulletin! You saved me a lot of hassle.

Here's my story: I bought my 2021 CX-30 three weeks ago. Today, the dealer provided valet service to pick up and return my CX-30 so they could install the accessory rails and crossbars. Not long after the car was returned I took a short drive and noticed that the TPMS wasn't working. No pressure values appeared and the view screen indicated "Updated 12/31/18". Tire pressures did not appear on the MyMazda App either. I followed the instructions in the service bulletin, re-enabled the GPS Time Synchronization (i.e. checked the box) and drove the car like less than 1/8 of a mile when the tire pressure values reappeared. Like magic.

I do wonder why the dealer disabled the GPS Time Sync. Or perhaps the valet driver wanted to have a little fun on his way back to my house without anyone knowing, who knows? But the dealer service manager is going to get a phone call from me tomorrow to ask about this business.
