Today i was driving and the average miles froze at 18 for a while. It didnt move and i must have driven a good 7 miles. when I was at a red light i turned the car off to see what it showed and it showed 14 miles per kwh which is impossible. I was going 45 to 50 miles a hour. eventually the numbers started to go down to about 7 by the time i got home. Does this have something to do with the software update of that module i did last week. I never had that happen before the software update. is there a problem or is this the way it was supposed to act all along and the software update corrected it.
