Thanks that's good to know. On the subject of expediting service, I had no luck. I called on Monday and they checked the schedule. Nope, nothing has opened up so I have to wait. I asked about Tesla Ranger. They put me in contact via a web link. Short answer: they're even busier.
Interestingly, although this is a minor issue for me right now (but it's getting worse) in reading the Massachusetts Lemon Law, there is the "dealer gets three times to try to fix the problem" that everyone is familiar with. However, there is another paragraph that says if the car is out of service for a total of fifteen business days, the manufacturer has to replace or buy back (your choice) the vehicle from you.
So, the way I read that, if you have a problem that reasonably prevents you from using the car, and Tesla is too busy to fix it, after 15 days you can return the car and recoup all your costs, except they can discount a reasonable allowance for your use of the vehicle (I read that as a discount based on the miles you've put on the car).
If i read it correctly, it's a cumulative 15 days during the warrantee period. So, if they take 10 business days to fix one problem, and then another 5 business days to fix another problem, you can invoke the lemon law. There's one other clause that says basically that they can get an additional 7 days to make it right, I think that's so that if they don't realize the two or three problems you've had are exceeding the 15 days, they get a final chance to fix the car.
Anyway, I was a little surprised that they only get 15 business days, but when you think of someone who depends on their car to commute to work, I think that's pretty reasonable. I don't see anything about loaners, so it seems like even if they loan you a car, if they can't fix it within 15 days you can return it. Not that I want to return my car, but it's an interesting bargaining chip when it comes to getting service on the car. I suspect you could drop it off at the service center without an appointment, and the clock would be ticking. Of course, IANAL so there are details I could be missing.
