## What is wrong

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.


## What can happen

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.


## The 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.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.safercar.gov.
