This is for model year 2014 FFE: As noted in the title, my 21-24 miles of total ev range has been down to 16 or 17 (apples to apples with no heat or ac on and late spring comparison) during the last 12 months. I hear the dealer is very dodgy when dealing with in-warranty battery replacements due to degradation. What do you all think? I use 220v home charger and usually run battery to empty.
