TP, that is exactly what it looked like!
Luckily, disconnecting the battery and reconnecting it set everything back to normal. It was just really bizarre to have the cluster start reading everything in European specifications. I was concerned that the memory for the miles and everything had gotten deleted or something.
Although, I was looking forward to turn past the 1 million mile mark and having the display start reading from 1.
So why would the car do this?
