The National Highway Traffic Safety Administration has asked Tesla to recall some 158,000 Model S and Model X vehicles that could suffer from failing display consoles, according to a letter published by the agency on Wednesday. The failures of the so-called media control units in these vehicles can sever the owners access to their vehicles backup camera, climate controls, and Teslas Autopilot driver assistance system, increasing the risk of a crash, the safety agency says.

The problem at the heart of the defect that NHTSA wants Tesla to fix involves worn-out flash memory chips used in the displays of 2012-2018 Model S sedans and 2016-2018 Model X SUVs. Each time an owner turns on one of these Teslas, it eats away at the total capacity of the the 8GB eMMC NAND flash memory chip onboard the NVIDIA Tegra 3 processor that powers the displays. When that capacity is reached  usually about five to six years later, the agency says  the displays become bricked. Motherboard first reported on the issue in 2019.

Tesla confirmed to NHTSA that all units with this chip will inevitably fail, according to the agency, and also provided a statistical model showing projected weekly repairs lasting from 2020 to 2028, with the most failures happening in 2022.

NHTSA opened a formal investigation into the problem last June, and said Wednesday that the probe is still ongoing despite the request that Tesla recall the vehicles. Its unclear if Tesla will comply. The company did not immediately respond to a request for comment.

In the letter, NHTSA acknowledges that Tesla has issued over-the-air software updates meant to mitigate the failures, but the agency believes those dont go far enough  especially because the problem cuts access to the backup camera, which is now a federally mandated feature. [T]hese updates are procedurally and substantively insufficient, the agency writes.

While Tesla popularized the use of large touchscreen displays in cars, it had more than one problem with these earlier models. Beyond the flash memory issue at the heart of NHTSAs recall request, early Tesla displays also suffered from bubbling and yellow banding since they were not up to typical automotive standards.
