I haven't had any of these problems and I wonder if it's because I didn't use the car on Friday and it only affects cars that were in use at the time.
Perhaps it was an OTA update and the line of code that prevents its installation if the car is "on" was missing or corrupted. That could explain why they seem to be back to normal after they've been left overnight so the update can install itself.
