Ultrasonic Sensor

For days, I've gotten the warning that my ultrasonic sensor has failed and driver safety functions are disabled.

Adaptive cruise works, and when it shows the car in overhead, it has an x on the front right sensor.

I'll take it into service, but just seems odd. Not sun or snow, as it happens in the dark too.

Outside the sensor looks fine. I cleaned them all and the windshield, as I thought the ultrasonic was behind the mirror.

Anyone else have failed sensors that triggered this. The only issue it gives me is that it doesn't beep for front proximity.

I found the one that is bad. If you have it setup for the front camera to show when you go into drive, it has a red x over the bad one. It has a bump (not a dent) in it.

I will get it changed when I do my oil change.
