2018 CX-5 Weird peep sound during nighttime

:
2018 CX-5
Hello all, I have this random peep sound that's been driving me crazy. It is totally random and I'm unable to exactly pinpoint where it is coming from or associate it with any triggers except that I only hear it during night time driving not day time, which makes me suspect it's related to a brightness sensor or something like that?

I started hearing it after a dealer service that included a full break job with changing all brake rotors and break fluid. I intend to ask the dealer about it in an upcoming service but wanted to get your input if anyone encountered something similar?

Appreciate your input.
