Not sure what the update was that I first started having same problem. Did the resets per e-mail instruction from Tesla helpers, still not working correctly. One of my "trips" has about 1500 miles and indicates I've only been using 21 wH/mile. Oddly, a trip yesterday, the only accurate info was the amount of time of travel, distance was way low, and wH/mile was way off. Odometer (total miles) remains OK, but the "trips" clearly display bogus info. Quite annoying to a data hound.
