Just got my model 3 a little over a week ago and so far really like the car except for the fact that auto pilot, cruise control, and automatic wipers haven't been working. Drove the model X for a while, so definitely missed the auto pilot feature in the past week. Initially thought that it might be still be calibrating, but after driving a few hundred miles, I made an appointment with the service center and just found out today from them that an incorrect front camera was installed and they are ordering a new replacement for it. Assuming their diagnosis is correct, I'm a bit rattled by this. Being a software engineer, it just leaves me wondering, how do they allow a car with incorrect hardware to be delivered? It seems like a relatively simple software check to ensure all connected hardware is as expected. And this experience just leaves me wondering, what else in the car is incorrect but just not as easily noticeable. For example, did they even install the correct airbags? It's quite baffling that a completely incorrect part is installed into the car. Anyways, just posting about my experience and wondering if anyone else has had problems as major?
