Seems to have worked itself out. I am charging at 40 the previous owner only got 36. I travel 12 miles and use only 7 miles of range. I charge up with 120 volt and it charges easily in less time than my 75 mile Ford Focus Electric. I truly do not understand why Chevy Volts have such a low resale value. I have 62,000 on the car and it does not look like the battery pack is any worse for the wear.
