Mine went to 99.9 mpg for a few weeks and i couldn't figure out why. Then one day i noticed it had started working again. Never figured out why and never looked into it further. I am still on original battery and no other issues were occurring during the few weeks my mpg summary was at 99.9. Car is a 2013. Odd.
