Feds asks Tesla to recall 158,000 vehicles over failing touchscreen displays

U.S. security regulators have requested Tesla to recall 158,000 automobiles over media management unit failures that trigger the touchscreen shows to cease working, following a months-long investigation by the National Highway Traffic Safety Administration.

The Office of Defects Investigation unit of the company decided that the failure of the media management unit is a security subject since capabilities just like the backup digital camera and defogging and defrosting setting controls cease working in addition to audible chimes, that are used when the flip sign indicator is activated and to alert drivers whereas the car’s Autopilot superior driver help system is engaged. Reports of the MCUs instantly failing have been a subject for years in Tesla boards.

The failure is brought on when the reminiscence storage in a flash drive used within the utilized in these automobiles reaches capability, investigators concluded. The solely answer is to switch the bodily piece of {hardware}. Vehicles affected embody Model S sedans constructed between 2012 and 2018 in addition to Model X SUVs in 2016 by means of 2018.

Tesla didn’t reply to a request for remark. However, the corporate did present data to NHTSA, which is contained within the report. Tesla confirmed to NHTSA that every one items will inevitably fail given the reminiscence system’s finite storage capability. Tesla supplied its personal statistical mannequin exhibiting the variety of projected weekly MCU repairs from 2020 to 2028. The automaker estimated that alternative charges for MCU failures will peak in early 2022 and regularly decline till (close to) full half turnover has been achieved in 2028, in response to the report.

These automobiles are outfitted with an NVIDIA Tegra Three processor with an built-in 8GB eMMC NAND flash reminiscence system. Part of this 8GB storage capability is used every time the car is began. The eMMC NAND cell {hardware} fails when the storage capability is reached, leading to failure of the MCU, the company mentioned.

The eMMC NAND flash system’s lifespan based mostly upon the variety of program/erase cycles, after which the MCU fails resulting from reminiscence wear-out. Investigators decided that the anticipated utilization life ranking for the 8GB eMMC NAND flash reminiscence system is about 3,000 Program-Erase cycles, after which the eMMC NAND flash reminiscence system would change into totally consumed and now not be operational. At a day by day cycle utilization charge of 1.four per block, accumulation of three,000 P/E cycles would take solely 5 to six years, the company mentioned.
