A friend bought a Tesla that came with a defective rear window from the factory, they found out when opening the door at home. A tech came out and sealed the door shut so the car could be used. It took 10 months before the car was repaired and the door was usable.
Their next purchase was not a Tesla, future purchases will not be a Tesla ever again. Just by the quality of their product.
Ya, this is the sort of thing which would keep me from buying Tesla. While Musk's antics certainly don't help, everything I hear about Tesla tends to revolve around poor quality control, terrible customer support and long delays in getting problems fixed. Even without Musk, I wouldn't want any part of that.
