Warning problems of the 2015 Tesla Model S

When my mcu fails, I receive a message that says, "autopilot safety/convenience features unavailable. " Tesla's text messages to me state: - "the issue that you experienced with the center display resetting . . Was a continuation of the firmware issue we had identified. . . "- "this was caused by a known firmware issue",- "we do have a couple of known firmware issues that causing occasional resets or slow performance",- "since there are no repairs to be made at this time . . I will go ahead and close your service request" [and effectively refusing to repair my car under the warranty adjustment program] this issue is not an academic or financial one. I was driving on an interstate freeway in heavy rain approaching a needed charging stop when I suddenly lost control of the heat and defrost systems, the cruise control, all navigation displayandcontrol, and the "safety systems" which I assume are aeb. I had to either risk pulling over on the freeway, which is never completely safe, or scramble with the navigation on my phone to make sure I know which exit to take. On several other occasions, I have lost similar systems and the back up camera feed as I was backing up or needing to back up. Tesla has refused to honor its warranty adjustment program in writtentext messages, is creating an ongoing risk to the public, and seems to have, in addition to the known memory issue, a known but uncorrected software problem that significantly implicates safety. I strongly encourage NHTSA to follow up on the issues raised by Tesla's actions ASAP. Thank you for your attention to this matter.
