Tesla admits a malfunction of touch screensNovember 12, 2020
It all started back in 2012, but it’s only now that Tesla has recognized a problem that should have long been of interest to the National Highway Traffic Safety Administration (NHTSA).
The California-based automaker has finally admitted Media Control Unit (MCU) touchscreen failures on Tesla Model S and Model X from 2012 to 2015. In many cases, owners were simply left with a useless touchscreen, but Tesla argued that it was out of warranty. Apparently, the intervention of the federal authorities still forced Tesla to settle this issue once and for all.
The company has announced an additional warranty for its old MSU touchscreen. The new MCU began to be installed in 2018, and was not noticed by its predecessor problems, which included slow response, longer turn-on times and system freezes requiring a reboot, and in many cases, complete failure. The reason for this problem, according to the owners, is associated with the multimedia card built into the MCU. The display processor flash memory device has a limited life, and MCU failures are likely due to wear and tear.
“For the peace of mind of our customers, we provide an additional warranty for some Model S and Model X vehicles manufactured before March 2018, which are equipped with an embedded multimedia system with an 8 GB card (‘8GB eMMC’) in the multimedia control unit. We are aware that this component can malfunction due to accumulated wear and tear. This condition does not affect basic driving and handling, and we are not aware of any injuries or collisions associated with it, ”Tesla responded to the affected owners.
Given the potential security concerns, it’s surprising Tesla didn’t take action early. It is also somewhat surprising that Tesla did not include a fix in its recent $ 2,500 infotainment update that improved older versions in both vehicles and removed AM / FM and Sirius XM radio. By the way, radio can soon be restored for an additional $ 500.
