Repair progress

45,455 of 134,951 vehicles in this recall had still not been repaired as of Q1 2023.

66% repaired — 89,496 of 134,951 reported

Manufacturers file these figures with NHTSA each quarter. Vehicles the manufacturer could not trace, or that have been scrapped or exported, are counted separately and are not included in the unrepaired figure.

What the defect is

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 could 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.

What gets fixed

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.

Your rights

A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.

That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 29 January 2021.

To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.

Additional 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.

Check your own vehicle

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.

A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
