Strange 2.4 bugs - remaining range in km - just me?

I had my 2.4 update earlier this month and have noticed a couple of odd things happen on a number of occasions now. I basically get a few simultaneous errors occur (things like ACC not available, dynamic road sign recognition not available, etc.) and my remaining range on the dashboard switches from miles to km - all at the same time. All goes back to normal on the next drive. Also doesn't happen on every drive, of course. Surely I'm not the only one?
