I purchased my MX new in June 2017 and have free supercharging as long as I own it. I'm taking a weekend trip from Sacramento to LA (something I have done 4-5 times). When charging at the Santa Clarita station today, I was incurring a charging fee for the first time. When I noticed that, I moved to another station and that one was charging me as well.. No problem with the other 3 other supercharging locations that I use on this trip. Interesting enough, when I went to the My Tesla page, the usual statement about free supercharging was nowhere to be found. I will contact Tesla when I return home, but I was just wondering if anyone else has encountered this?
