My S model was hit in a parking lot. I have been waiting for over a month and a half for a replacement driver's side rear quarter panel. The local Tesla service center tells me a quarter panel is not available. The car has been in a certified Tesla repair shop and cannot be driven. The car is only 5 years old. The latest information I received from Tesla did not have any date as to when a panel might be available. I'm in San Diego. How can this happen that no rear quarter panels are available in the US for a five year old model S?
