Rear parking sensors

[ScoFair]

My rear parking sensors appear to have stopoed working. Any one else had a similar fault, or is it possible my wife has accidentally found a button or setting to switch them off?

The fronts are working fine by the way.

Scott i had an issue last year it was ice on sensor or dirt when thaw came it was ok.

This has been after a clean and fairly reasonable mild weather .... although frosty this morning.

I haven't used a high pressure hose while cleaning, as i believe that can cause issues .... so can't understand

On the RX I believe there is a menu setting where they can be disabled, so maybe something similar on the UX.

On other cars I have had you usually get an alert along the lines of "Clean Parking Sensors" rather than they just stop working.

I'll have a nosey thru the menu and see if i can spot anything obvious thanks
