Problem since Dealer performed TSB-2245. When I got the car back the range changed from 255 mi 90% charge to 180mi range. I thought they may have caused a reset. Now that I have been driving for a couple of weeks the mi/kw has dropped from 3.4 mi/kw average around town to 2.5 mi/kw if I am lucky, average daily temp has been the same as before the update. I just drove 24mi (fairly flat terrain) at 70 mph and my charge state went from 80% to 62% the OAT is 88 degrees. Also when I charged at an EA 350KW the max rate was 30kw and dropped to 21kw at 79% tried several chargers (88F outside). Premium 4X
Does anyone have an idea why the TSB would cause this.
