Also, note that it's not just a restriction on taking them to court about the repair, but also an indemnification against any wrongdoing in "related" incidents and incidents leading up to the repair - i.e. suppose a known manufacturing flaw results in an accident which appears to be the drivers fault, and Tesla's offers this free repair, you also can't claim any medical bills later when the truth emerges. It's way too broad.
