If Tesla delivers new car to you and you see color,seats,lights or any other problem can you simply tell them you will not accept that car until problems are fixed?
I don't want to accept my car with problems (even small ones) and then deal with SC for weeks/months
Is it possible or you have to accept car as is?
Im not quite sure I am understanding what you are asking...
Yes, it is possible to REJECT delivery of the car assigned to you for any reason, when you go to pick it up.
Yes, it is possible to take delivery of the car, and then return it during the 7 day period.
NO, you will not be able to tell tesla "I am not taking THAT CAR" until you fix it, once you fix it THEN I will take THAT CAR". Unless something has changed with tesla (possible) it doesnt work that way. You reject the car, its rejected... not assigned to you until they fix it.
Its rejected and they assign it to someone else and see if they will take it, and YOU go back "into the queue" waiting for a car.
You are not going to be able to reject a car and tell them "im not taking that one until you fix it" to try to put pressure on them to "fix it fast".... which it sounds like what you are wanting to do (i may be reading what you are asking incorrectly however).
