You guys do realize that class actions are explicitly forbidden in the arbitration agreement, and the US Supreme Court (at least in the employment law context) has upheld such language. Right? The moral of the story: use the only other alternative to binding arbitration: Small Claims Court.
The language:
"The arbitrator may only resolve disputes between you and Tesla, and may not consolidate claims without the consent of all parties. The arbitrator
cannot hear class or representaive claims or requests for relief on behalf of others purchasing or leasing Tesla vehicles. In other words, you and Tesla
may bring claims against the other only in your or its individual capacity and not as a plaintiff or class member in any class or representative action."
