I just searched for my VIN on the Tesla recall page. This is what came up for my car:
Recall Date| Feb 2, 2021
Refresh Date| Feb 2, 2021
Recall Number 21V035
DESCRIPTION
The eMMC flash memory device is rated for an industry-standard 3,000 Program/Erase (“P/E”) cycles. Over time, and depending on usage of the affected component, the eMMC hardware exhausts cycles for each NAND cell. When the eMMC NAND cell hardware reaches lifetime wear, as measured by the number of P/E cycles and remaining available storage capacity, the eMMC controller will no longer be able to maintain the integrity of the filesystem. This wear-out condition can cause failures of the center display software components, and may indirectly cause loss of the rearview camera display, defrost/defog control settings, and exterior turn signal lighting.
STATUS
Status Recall INCOMPLETE
SAFETY RISK
Safety Risk While we are not aware of any crash, injury, or fatality resulting from this condition, unavailability of the rearview camera display, defrost/defog control settings for purposes of ensuring visibility, and exterior turn signal lighting may increase the risk of a crash. For vehicles for which these functions are not available, drivers can continue to operate the vehicle by performing a shoulder check and using their mirrors when backing, taking care when making turns, and assuring clear visibility when driving.
REMEDY
Remedy In 2020, Tesla deployed several OTA firmware updates to address certain functionalities that may be lost when the eMMC reaches accumulated lifetime wear. Specifically, on vehicles equipped with: • FW release 2020.24.6.11 or newer, the defrosting/defogging settings will maintain the user’s selection for the duration of the drive cycle in which the eMMC wears out. On all subsequent drive cycles, the defrosting/defogging settings will automatically set the ambient cabin temperature to 22 degrees C (71.6 degrees F) and initiate windshield defrosting/defogging to ensure sufficient windshield visibility. In addition, all exterior lighting controls and chimes will continue to function normally after eMMC wear-out. • FW release 2020.48.12 or newer, the rearview camera display will continue to display on the center display after eMMC wear-out and an alert will now appear on the center display anywhere from one to six months before the eMMC reaches accumulated lifetime wear to notify most consumers of the wear status and to inform them that they should contact Tesla Service. As of January 22, 2021, 88% of all US vehicles affected by this recall report are operating all the aforementioned FW updates. Based on the above, Tesla believes that the aforementioned OTA FW updates remedy any potential safety risk presented by the eMMC wear-out condition. However, in the interest of ensuring the best possible ownership experience for affected customers, Tesla will also replace the eMMC on all affected vehicles or reimburse any affected customers who previously paid to replace an eMMC, Visual Compute Module (“VCM”) daughterboard, or MCU that was determined to be caused by accumulated wear of the eMMC. The eMMC is a component on the VCM daughterboard within the MCU. To be specific, Tesla will replace the VCM daughterboard that has the Hynix 8GB eMMC with a VCM daughterboard that has an enhanced 64GB Micron eMMC, free of charge.
What I'm trying to figure out is how is this equal/better/less than/related to the MCU1 to MCU2 upgrade. I really want to do the MCU upgrade and was planning to order it the second I take delivery of my car (2017 MX) this week. Should I wait?
