2021 CX-5. Used to be mine and now the wife drives it. Front and Rear parking sensors do not appear to be working and I have just confirmed. No, I do not have a parking sensor button by my left knee, only 2 buttons. I do not know when they stopped but I first noticed at the end of July but didn't pay much attention. Is there a fuse or somewhere else I can start to trouble shoot this? Unfortunately I do not have sensors on my vehicle so I am unfamiliar with the system or Mazda's version of the system. Blind spot still works and so does the sonar/cruise control.
I have searched this forum and found nothing under "Parking Sensors" or "CX-5 Parking Sensors" so I am putting it to the group for suggestions.

Thank you,

 

I have no idea where that fuse is, it is not spelled out in the fuse diagrams most likely tied into one of the braking system fuses.
Replacing a fuse without knowing why it blew is not wise.
Best to have the dealer check this out as there are many things that can go wrong with this system.
Good luck

 

Thanks for your input and I agree, the fuse diagram is no help! Don't even know when it stopped working because my wife is not tuned into these things like I am I guess? I am allergic to most dealers but I believe this might just still be under warranty since it was purchased as "certified preowned". It is a 2021 that I purchased in early 22 and it came with a 4 year warranty.
Replacing a fuse when you don't know why it blew is nothing new. The vehicle has absolutely no aftermarket equipment installed that may have put additional strain on the system so I would like to think it just "blew". If I went to the dealer for every blown fuse in my life I wouldn't be able to afford a bus ticket.
Thanks again for being the person that responded. Maybe my next question will be "Parking Sensor Fuse"?

 

Time consuming, but you can start at the panel under the hood and pull each one to see which one it is that is blown.
If you don't find it, then start on the panel inside.
It's then up to you if you want to replace before you find out why it blew.
If you do replace it and blows again then you should definitely take it to a certified mechanic to find out why.
It is possible you will find no blown fuse at all, and that it is an electrical/sensor or programming issue.
