On the other side of this coin, my daughter has an X. The first week she had to have a part replaced, but since then I can't remember anything else. Since she always has to borrow a car when there's trouble, I'd know, but there haven't been any car borrowing over the five years she's owned it.
It has nothing to do with me being a Tesla fan. There are just no problems with my S, my wifey's 3, or my daughter's X. She's planning to buy another one this year. Of the people I know who own Teslas, no one takes theirs in for any unusual service or maintenance. I personally have owned four Teslas, accumulating over 250,000 miles, and have never been to a service center for service. I've owned plenty of Toyotas, and I clearly remember sitting in the waiting room many times with several other owners waiting for service to be completed, and this from a guy who changes his own oil (not any more!) Teslas are one of the best cars on the road, and this is just another factor.
For those of you who don't like hearing this, tough. Buy a Tesla and then tell me all the trouble you have. Doesn't happen.
