My family has had 4 cars in the last 15 years (I won't mention models, but they were fairly reasonable, middle-of-the-pack vehicles). Three of them had no defects at all. The most recent one, a hybrid with a bunch of fancy electronics, had just a couple of problems, covered under warranty and fixed in less than a day. (And if our dealers flake out, there are independent service and repair shops that can do the same job, or better).

When several of my Tesla-owning cow-orkers reported waiting six months for things like body panels, I resolved not to buy one.
