I've had my Model 3 for less than 6 months, and I've put about 500 miles on it. When I came off holiday I got in it at the airport and it had a buttload of errors..
I googled the errors and the common theme seemed to be the whole battery pack replaced.. not something you can reboot the car and fix. So I put it in for service.
They didn't have any courtesy cars so they arranged for a taxi for me back home. An hour later the driver phoned me to tell me he was on the way to take me back to Tesla. So I got there and they said it's going to be longer than a couple of days so they gave me a courtesy car.
They've had it for just over a month now.. I am apparently in the queue for a battery and it'll be mid next month.
I'm chill as fuck, and I love Teslas, and I get that this kind of stuff could happen to any car.. but 2 months?
