6 months, about 6700 miles. Absolutely nothing to report other than fantastic fuel economy.
I'm still running on my first quarter of the first full tank of gas. The car says 80 mpg after 310 miles but I don't know if that figure includes the first 20 miles at the dealer where they never charged the battery and the history shows 25-27 mpg on ICE (I assume customers were trying the sport mode acceleration out on the highway). What kind of fuel economy are you seeing after 6700 miles?
EDIT: I should note, I bought a new 2019 PHEV EX.
