> Tesla sells things, and they can't just give you a new one when it breaks.

Actually, they can. And legally, they have to (or offer a refund), if the car breaks as much as that one did. I don't think you quite grasp the magnitude of the issues being alleged.

> I once bought an suv. It had a problem [...] Eventually my car was repaired

Right, good story, but totally different than the OPs story, where he had tons of problems and they were never fixed.
