Something must have gone bad-- for comparison I bought my 60 in 2013, it has about 33,000 miles, and rated range with 100% charge is 200 miles (4% loss from the original 208). I wouldn't wait for the next service to have it looked at.
Thanks, and yeah, already have an e-mail into them. Want to get it, as well as a few other little things, taken care of before the waves of Model 3s start coming
