Car obstacle Sensor- 2012 Genesis 5.0

[derrickwi]

My front driver sensor has started flashing and beeping when I stop even though there is no obstruction, When I drive away flashing stops, Any ideas what could be wrong? Are these sensors easy to replace.
Thanks for any advice.

Maybe it is stuck? Spray it with something like WD40 and see if it will release.

How does an ultrasonic sensor get "stuck?"

Sensor seems to work OK now. Didnt do anything, must have corrected itself.

Maybe it had some mud on it?

No mud. It was clean. Also get hardly any rain where I live. I sometimes get rogue alerts howver this time it was more persistant amd predictable. Gone now though

I used the wrong terminology. The WD40 will clean it, "unstick" it. Not an uncommon issue. It can even have a bug on the sensor causing the issue.
