What about not keeping enough fresh oil? I believe keeping a minimum charge on an EV is analogous to the common knowledge of maintaining a gas-powered vehicle's oil. The problem is that people don't have experience with EVs.

I'm sure in the early days of gas-powered vehicles, plenty of engines seized up because people were unaware they had to change the oil and keep it at a certain level. And it certainly still happens on occasion.
