No my friend, they charge 482 to put your hand on the car and it can be more depending on how many hours they use to find the problem. But as I said, they don't fix parts, they replace them completely, for example... If they look at my battery and find a wire with a problem, they don't fix the wire and have the battery replaced completely, that's why I resist talking with Tesla.
So, if we are understanding what you have said here the situation is thus:
You purchased a 2014 Model year Model S, that had obvious damage on one side of the car, and you bought this car under verbal promises from the Dealer that the obvious damage you saw was "just a cosmetic issue". You were verbally told there was "nothing else wrong with the car" by said dealer, and did no other due diligence on the car to determine its status.
You purchased the car, and "a few days" after buying the car, you get all sorts of errors, then created an account here on TMC to ask about them. The dealer you bought the car from says "you bought it, its your issue now".
Does this summarize what has happened?
