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.
