Unfortunately it's been my experience that speaking with someone in senior management, or any level of empowered management for that matter, is nearly impossible with Tesla. You can't simply call someone locally who genuinely cares and has incentive to help you resolve your issue.
We've had some very serious issues spread over three different cars of every imaginable category and, try as I might, I was unable to find anyone with the power to actually resolve anything. You'll get people who empathize with you and promise to help and see it through to the end and get others involved who are empowered to help but then they ultimately ghost you or quit.
I was following your thread because I had hoped that someone may have some useful info but my guess is if anyone out there actually has a direct contact they're keeping that hand close to their chest.
This is my single biggest complaint with Tesla as a company. I was recently in the market for solar and after yet another bout with Tesla customer service sadly decided not to put ourselves out there for another $30k system that would likely require customer service at some point.
Customer approval ratings are trending downwards and Tesla is focused on turning profits rather than the customer which isn't going to help matters.
