That's hilarious!hihahihahihasounds like the world's first M5 Hybrid!!!
The S85 V10 provides power when you request it by pressing the M button but until then you have the microwave, toaster or whatever it is that powers the Prius getting you through the city and highway.
random glitchI reseted and everything is back to normal! 12.1 MPG. I feel a lot better! Thank you all. Another item I noticed is that the next service mileage did not change until I reseted as well! I am still wondering why that happened though!
Crazy, this just happened to me yesterday. Same mileage too. Went to 60k and I freaked for a second, saw km, and it went back to 40k mls.This happened in my E39 once as well. Was at the movies, got my car and looked down and saw 66,xxx and was like WTF as my car had only 4x,xxx miles. So confused, then saw km. Weird.
