Talking with the maintenance man at the garage, i asked him why i am not getting 240 miles (100%) maximum range. i got my tesla about 1month and a half. He checked my style of driving on the computer and said that i was driving a little more than normal that would effect my maximum at 100%. i was getting about 210 (100%) maximum range. First time i checked my maximum range. He told me to reset the mileage, drive my car without charging from 20% then charge it to 100% and parked for 2-3 hours parked. Then drive the car. Reboot not only the screen but the battery. Interesting. i will do that and see if i will get at least close to 240 miles (100%) maximum range. But i will drive more conservative.
