I bought my M3 is September. Originally the salesman told me I'd get a free year of Supercharging(I knew that was wrong because Tesla had stopped doing that). When I picked the car up I was told I was not getting any free supercharging miles. I wasn't happy, but a customer gave me a referral in the store and I was told I had 1,000 free supercharging miles. I figured I was halfway there so today I went to look up my account balance. Much to my surprise, it says I have unlimited Supercharging until Oct 6, 2021. Do you think Tesla is going to steal that back from me? LOL I took possession of the car on Sep 21, so I can't figure out why I am getting 2 years plus 2 weeks of Supercharging. It smells like a mistake to me that I hope doesn't change! I've seen threads about this topic, but I'm curious what the current Tesla policy on Supercharging credits is. It seems random.
