My mother's 2015 BMW 320d has needed to go back to the garage at 6 months old to have its sunroof replaced. A BMW 320d isn't especially high end, it's true - but I imagine that (aside from the engine...) it consists of mostly the same parts as something fancier like a BMW 335i or 335d.

My dad's 2011 BMW 640i, probably closer to the Tesla in terms of price point, seems to have been trouble free so far.

My 2012 M3 needed an entire new engine at 16k miles. Unfortunately, unlike a Tesla, replacing my motor can't be done in a couple hours (or for a couple grand).

But the fit and finish is fantastic!

My 2014 Fiat has started to turn into a rattle can. It is expected of these cars from what I've read. But considering I get 40+mpg, I'm fine with it rattling down the road.
