Comments
Problems like overheating have gone away from first year. Both new firmware and later new fan shrould have eliminated overheating battery but on super hot LA days the PEM still will get hot if driven hard. Three sheets swapped at about 12,000 miles. All new battery at 24K miles. Since 2011 about 20 percent of charging is 220V 40 amp
