NHTSA asks Tesla to recall 158,716 cars due to touch screen failure

The National Highway Traffic Safety Administration (NHTSA) has asked Tesla to recall the 158,716 examples of Model S and Model X to modify or replace the touch screen, also known as the Media Control Unit (MCU). Government officials are not worried that drivers will not be able to blow the goat’s bark to other drivers, but driving without a touch screen is a safety issue that increases the risk of collisions. explained.

In a letter sent to Tesla’s Legal Department, NHTSA investigated and integrated 8GB eMMCNAND into many examples of Model S and Model X built between the 2012 and 2018 model years. It was revealed that it was equipped with the Nvidia Tegra 3 processor equipped with. Flash memory device. It’s this part that fails, and because it has all the touchscreen-based features, the driver can’t use the rear-view camera and can’t turn on the defroster or defogger. Investigators also pointed out that the problem was having a negative impact on the autopilot.

According to an internal document sent by Tesla to NHTSA, the failure rate of the touch screen was 14.2% to 17.3% in the example of Model S manufactured in the 2012-2015 model year, between 2016 and 2018. It was 1.9% to 4.1% for manufactured cars. The investigators emphasized that they expect failure rates to accelerate over the next few years as cars get older, adding that Tesla’s predictive model confirms this hypothesis.

“As the vehicle continues to be used [sic]After that, more memory blocks will be consumed and the life of the 8GB eMMC device will be shortened, leading to the inevitable failure of the MCU.Considering Tesla’s project [sic] Of the MCU repairs, even the target vehicles in 2018 will have 100% failure of the MCU within about 10 years. “

Like all processors, Nvidia’s Tegra 3 unit has a finite lifespan. The flash memory device can withstand approximately 3,000 program erase cycles before it needs to be replaced. Investigators have found that it will take five to six years to reach that point. This is a time frame labeled inadequate given the much longer life expectancy of modern cars.

In other words, simply replacing a dead touchscreen with the same new unit is not enough for regulators. In November 2020, Tesla began addressing the issue by removing the faulty 8GB eMMC and installing a longer-lasting 64GB unit. Theoretically, you can solve the problem by placing this part in every affected car.

Tesla has not commented on the request. You can accept the NHTSA findings and bring back the affected vehicle or appeal the decision. You must reply by January 27, 2021.
