Radar sensor issue? 2021 MSLR

[DarkKNT]

Since yesterday while driving more than 10mph, the instrument display shows my left radar sensor flashing red as if there’s something close by. I’ve done a reset and waited for 24 hours but it still shows up when I drive. I have a full front clear PPF installed back in Feb with no issues u til yesterday. Anyone else experience this?

Minor detail, but that's an ultrasonic sensor to my knowledge, not a radar sensor.

It's possible that something has hit the sensor and it's come loose?

You are right. Possibly, nothing unusual has happened while driving but noticed it starting yesterday. I don’t get the red lines when parking in the garage or under 10mph.
