Ive been gone a while, but im back in a 2008 XJR!

Ive been absolutely stumped by this issue - Any cell phone recording audio or placing a phone call will pickup the ultrasonic occupancy sensors while the car is on. Google Pixel Pro 7 noise is the worst, It also does it on an Iphone 12, just not as bad.

Ive searched all over the web and found posts from 2013 where iphone 4/5's and some hearing aids picked up the ultrasonic sensors, but havent found anyone who's experienced this issue more recently. My old 2005 XJR did not have this issue.
Battery is new, grounds by headlights & battery have been cleaned. Does any have any idea why these sensors are so loud on my particular car?
