I just received my new M3P (< 200 miles on the odometer). I left the max charge at the default of 90%. When charged to 90%, the range reported is only 263 miles, which works out to 292 miles @ 100% charge. That is quite a bit lower than the 310 mile range it is supposed to get. Is this an indication there is a problem with the battery installed in my car? I was thinking maybe I need to calibrate the battery by, say, charging to 100% then running it down to 10% or something like that.
