Recall Bulletin: Recall Bulletins are mandatory service procedures that must be carried out by Tesla-certified Service Centers. Recall work performed by uncertified technicians could lead to unsafe conditions or voided warranty provisions.
This Service Document supersedes SB-21-21-001, dated February 1, 2021. Each content change is marked by a vertical line in the left margin. Discard the previous version and replace it with this one.
Condition
For some Model S and Model X vehicles built before March 2018, an 8GB embedded MultiMediaCard (“8GB eMMC”)
in the Media Control Unit (MCU) might malfunction due to accumulated wear. This may result in a blank or intermittently blank MCU display and/or prompt an alert on the MCU display that a memory storage device has degraded and to contact Service. If the eMMC malfunctions on a vehicle running software older than 2020.48.12 it may lose access to the rearview backup camera display, exterior turn signal lighting on subsequent drives after eMMC malfunction, and access to windshield defogging and defrosting controls.
Correction
The purpose of this recall is to install software release 2020.48.12 or newer to address all potential safety concerns.
Additionally, this recall is to proactively upgrade, free of charge to the customer, the available memory storage from 8GB to 64GB. Replace the Tegra Visual Compute Module (VCM) Daughterboard containing the 8GB eMMC with an upgraded component and ensure that the vehicle is operating FW 2020.48.12 or a newer release.
NOTE: During the initial rollout of this recall bulletin, parts will be constrained. Owners were informed the only action they need to take to address all potential safety concerns is to confirm their vehicle is running software release 2020.48.12 or a newer release, and they will receive further notification when proactive replacement parts are available. Apply the bulletin if any of the following conditions are met:
- The owner has scheduled an appointment as a result of receiving a notice letter indicating that parts are available for their VIN.
- The vehicle has experienced a malfunction of the eMMC filesystem. A reference section at the end of this document describes how to determine if the eMMC filesystem malfunction is due to accumulated wear.
- Automated diagnostic results indicate to apply the bulletin, even in the absence of a malfunction.

1 Associated Investigation
Loss of rearview camera
NHTSA ID: EA20003
Dated opened: November 12, 2020
On June 22, 2020, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE20-010 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-2015 Tesla Model S vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. EMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles. The subject MCU allegedly fails prematurely due to memory wear-out of the eMMC NAND flash. Tesla used the same MCU with the Tegra 3 processor in approximately 159 thousand 2012-2018 Model S and 2016-2018 Model X vehicles built by Tesla through early-2018. In response to ODI’s Information Request (IR) for PE20-010, Tesla provided ODI with 2,399 complaints and field reports, 7,777 warranty claims, and 4,746 non-warranty claims related to MCU replacements. The data show failure rates over 30 percent in certain build months and accelerating failure trends after 3 to 4 years-in-service.
According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware can fail when reaching lifetime wear, for which the eMMC controller has no available blocks to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided the effects of MCU failure on vehicle function which result in loss of rearview/backup camera, loss of HVAC (defogging) setting controls (if the HVAC status was OFF status prior to failure.) There is also an impact on the advanced driver assistance support (ADAS), Autopilot system, and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. There are precedents for addressing defects that result in loss of either backup camera, defogging, or turn signal functions under safety recalls.
Tesla has implemented certain Over-The-Air or OTA updates to subject vehicles to mitigate the effects of MCU failure. These updates include firmware changes to reduce memory usage of the subject memory card, improve eMMC error correction and storage management strategies, changing the control logic for turn signal activation, and defaulting the HVAC system to Auto (71.6F) for drives after MCU failure to address windshield defogging. Tesla indicated that the MCU failures are likely to continue to occur in subject vehicles as vehicles continue to operate and use available memory in the 8GB eMMC NAND flash memory until 100% of units have failed.
An Engineering Analysis has been opened to further assess the scope, frequency, and safety-related consequences of the alleged defect.
The VOQs associated with the opening of this investigation are in the attachment to this resume.
