Though all other points in your comment are quite juvenile, I think the first one is valid. >the suspension ball joint experienced very abnormal rust. We haven’t seen this on any other car, suggesting a very unusual use case. The car had over 70,000 miles on it and its owner lives down such a long dirt road that it required two tow trucks to retrieve the car. (One to get the car to the highway and one to get it from the highway to the service center.) When we got the car, it was caked in dirt. So what, Tesla? Cars are meant to be caked in dirt, sand, water, whatever elements they may encounter in the course of use by people who buy them. Most people drive on roads but some do go off-road and the cars should be able to handle it. Just the information provided here does not indicate misuse. It may still turn out that way, but not right now. It is more likely, IMO, that your engineers failed to consider some particular scenarios and the suspensions in your cars are a bit less rust-resistant than they should be.
