Replaced CVT at about 200,000 miles.
IMA Battery is currently dying at 295,000.
It's cost me about 4 mpg.
My mileage is strictly dictated by my driving speed. If I keep it under 60 on the hwy I can get around 55mpg.
None to date.
Future - mod the nut behind the wheel. Start keeping a log and moding my driving habits.
