Sounds like you need a locking charge port cover. Someone must be siphoning electrons out of your battery.I was under the impression that 100% charge would be around 320 miles. I would even be ok with 300. But when I plug my truck in to charge to 90% it says it will be at 248 miles... That comes out to 275 when fully charged at 100%. Anyone else getting similar numbers?
Do I need to check any cables?
