Sue Tesla. It's their responsibility for this garbage. You will get all the incriminating data during discovery.
That's...not how it works.
Anyone injured as a result of a defective product has a claim against the manufacturer and anyone else in the chain of commerce. You don't have to sue someone else and let them sue the manufacturer.
(You can, but you don't have to, and its a complicated tactical consideration as to whether it is optimal in any particular case, further complicated by the fact that you can also sue everyone who might be liable at once, instead of picking and choosing who is best to sue.)
If you want to go for the giant settlement from Tesla, that's a different lawsuit, much higher-risk, much more expensive and much higher reward (financially, media attention and changing behavior).
It would be likely cheaper to buy a whole new car every year for five years than to take Tesla to court.
