Hi- not sure how else to describe this, but each of the last few days, when starting after sitting for some time (Ti, sport package, driver static assist), I hear a small but audible "pew pew pew" sound that seems to originate from the mirror control area (or something near by). It's very tonally consistent, and repeats 3-5 times, so I'm wondering if it's something intentional (a warning chime that I hadn't noticed previously?) or...I honestly can't say. I'll try to get a video of it, but curious if any other owners have heard this or know what it might be? Something to worry about?
