I just took it to the shop today. The noise was quite weird and loud and disconcerting, to the point that I didn't park in my garage last night out of worry (paranoia?). Of course when I pull up to Service the car won't make the noise and is behaving normally - thankfully I recorded a video of it. I played the video for the service guy and he just said "It definitely should NOT sound like that!" and then when I told him the rest of the issues he just said "We may need to keep it for... a while."
In addition to the sound system not working and the audible alerts not working, overnight it lost all my display presets and reverted to default (the one-dial driver's display now two dials, smart settings gone, etc...).
Service was great (Jaguar Cary in the research triangle in NC), fit me in and got me a loaner immediately. The F-pace is ok, but it's no I-pace, and I miss my car already...
Hopefully a relatively easy software fix. We'll see.
As I said, JLR Cary is great (for anyone in the area), as is the same group's Mercedes dealership next door where we get all my wife's vehicles. Just FYI!
