You should NOT fight SC. Work with them instead. My assumption is that they are feeling your pain and even though they are in a different position than us it is questionable how much influence they have. The fact that they are doing work that you think is "pointless" would mean that they are trying to help at the best of their capacity. It is of course not optimal, but Tesla should be able to resolve this internally. Although I agree this is counter intuitive.
In addition, I will mention that, according to the feedback from more and more owners in this thread, the revised version ...77-C has only partially addressed the problem. Tesla itself has pointed out in their public message that they have partially resolved suspension issues. 65% to be precise, according to the source:
12 Models Lose CR Recommendation Over Car Reliability Issues Which issues are they referring to is still a mystery for me, but provided I have not heard about or experienced any other issues than this one Tesla is working towards a complete solution still. This needs clarifications however.
Other than that, if I were you, I would use applicable instruments in such cases like reporting about errors, diagnosting with SC.
If you absolutely have to - appeal to legal council. There is also an option to collaborate in such cases if the problem is not taken seriously enough and it is not only your individual opinion.
It takes time unfortunately and believe me I feel both pain and irritation, and waste my time on this. But here we are and the choice we have is to bear with Tesla or leave. But so far Tesla has shown dedication and, probably clumsy, but progress.
