Mitsubishi i-MiEV lack of range
i have had my car for 13 months and experiencing reduced range. the first 8 months i was getting 72-78 mile ranges driving in eco mode 90% drive mode 10%. my trips never change commuting within 8 miles of home 50/50 highway/ city. i started noticing range going down to 65-69 back in oct. and the past two months the range has been 60-63 in the cold months of jan and feb here in PA my driving habits and driving trips never vary , top speed traveled 55mph. i park in a garage and charge on a 120v household outlet. my thoughts are the battery is degrading something i have read about in the manual. i never recharge unless the battery is down to 4 bars or less. i also noticed when i recharged outside at a public station with outside temp. at 20 degrees the battery charge even tho i had 16 bars was not full because my range showed 54 has any one experienced these problems?
