NHTSA Complaint #11437038 — 2017 TESLA MODEL S

I am asking [XXX] a mgr. at Centinela Tesla for a refund of the money I spent on an upgrade for the model S which after being installed began shutting down intermittently. Tesla's system records all shutdowns of the cars screens, so If Tesla does not have records of the cars screens shutting down prior to the upgrade, this would indicate it did begin with the upgrade.  The NHTSA made a recall for an issue with the back up cameras which was when TESLA offered me a 1500.00 dollar upgrade instead of the free NHTSA recall fix, saying it was better.  A [XXX] at Torrance Tesla said he saw 2 shutdowns recorded in the week prior and did not have time to look up beyond that week.. [XXX] gave me a free accessory saying sorry for your problems but this is all I can do.  The receipt for the free accessory states it was given at no charge for the troubles with the screens. Tesla's mechanic explained once the upgrade was completed to make the dash cams functional the system must shutdown & restart to rid it self of data accumulation. The cars screens did not shut down prior to having the upgrade because the dash cams only became active as a result of the upgrade hence creating the data which must be expelled by shutting down.  Once this issue becomes evident to the customer Tesla simply tells you we don't have a workaround for this issue and sends you on your way.  Befoe agreeing to the upgrade I asked [XXX] a manager at Centinela Tesla that preformed the installation if this upgrade would make the on board camera system function as dashcams, which she said yes.  We communicated through text so there is a record of our conversation.  After four months with the issue I sold the car.  [XXX] please make my refund, so I don't need to take this issue to small claims court. [XXX] date is 09-13-2021 Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
