2009 genesis tech parking sensor false alarm

[2009genesis4.6]

I noticed I get a false alarm from my front parking sensors when pulling up to a light sometimes. It's intermittent and does not happen to often. It can happen when it's clear out and no one in front of me. It only beeps for a second or two then stops. Do you guys think this is normal? Any info would be great.

Same thing happening on one of the new intersection, near my home.

Every once in a while it does this also.
