We need to stop being apologists for Tesla QC and build quality. Until then we won't get improvements. Yes, these things can happen with all car makers but they are very rare, with Tesla they aren't.
We would all have better cars if Tesla had licensed their drive train and battery tech to Audi or Mercedes.
I know a lot of people who have had problems with Mercedes, serious problems, in my case engine loom "wore out" because they ran it between the engine and the body and there was insufficient room the ongoing problems were disruptive. In petrolhead circles, the big German manufacturers are not exactly considered to be high reliability - certainly not when you get to the high performance models which are probably more of a relevant comparison to a Tesla. Im not defending Telsa, they have room for improvement, but to say other manufacturers problems are rare is not something I have found to be true in practice. (there may be statistics available to prove either side of this argument, but I haven't investigated them).
