A Class Action would fix this issue long term for all Tesla owners... we just need someone to step up.
I believe the warranty excludes a class action suit in the same way as requiring arbitration. This was enabled by law many years ago. They do have to give you an opt out, but the company can limit that to the first 30 days and require it to be sent by mail.
I've learned my lesson. Anything I buy worth more than $100 means I send the letter with a return receipt. I wonder if your rights are still preserved if they refuse to sign for it. lol
