Tesla has not be able to tell me why my 5800 mile/8 month old MY has pronounced range loss even though I have been super easy on my battery (no DC charging whatsoever, only charged to 100% once, mostly operate in SOC range of 50-70% since short daily drives, non aggressive driving habits, moderate coastal CA climate, etc). Teslafi has my vehicle dead last out of 200 vehicles with a projected max range of 278 (vs EPA 326 rating). I have tried the recalibration efforts per other posts (deeper cycles, etc) but so far not working (will keep trying). Here's my question: While it might sound strange, I live on top of a hill and my drive home involves a steep climb of about 700 feet over about 1/2 mile. A Tesla mobile tech came out the other day to work on something unrelated and when I asked about my battery issue, he commented that "maybe" this steep hill ending every trip home might have something to do with the issue. Anyone have any thoughts on this? Any possible technical explanation?
