  Tesla, Inc. (Tesla) is recalling certain 2012-2018 Tesla Model S and 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. When the 8GB eMMC NAND flash memory device for the center display reaches lifetime wear, the eMMC controller will no longer be able to maintain the integrity of the filesystem, causing a failure in some of the center display functions.

  Risk: The eMMC controller wear-out condition can cause the loss of the rearview camera display, defrost/defog control settings, and exterior turn signal lighting, reducing visibility and increasing the risk of a crash.

  Remedy: Owners should ensure their vehicles are operating firmware release 2020.48.48.12 or newer, which will alert owners if the eMMC is approaching lifetime wear. Tesla will notify owners, and will replace the VCM daughterboard with one containing an enhanced eMMC controller, free of charge. The recall began March 29, 2021. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-21-21-001.

   The MCU that controls the climate and Advanced Driver Assistance Systems stops working while driving. I sent a service request to TESLA and they replied that my older MCU1 is failing because of the new software updates. It isn't the eMMC card hardware failure, but the symptoms and safety concerns are the same. None of the controls work, as the main screen goes blank and resets while driving. TESLA told me the fix for this problem is to upgrade to MCU2, which they fail to…

    When driving with autopilot engaged, the vehicle sometimes gives alerts even when there is no vehicle or obstacle in its path. Immediately once the driver takes control, the autopilot does not disengage but continue as usual. The autopilot suddenly brakes or slows down even when there is no obstacle on a freeway.
