Tesla is recalling 130,000 cars due to a software issue that causes the AMD Ryzen CPU in vehicles' infotainment systems to overheat during fast charging.
The issue is potentially making the car's touchscreen malfunction or go completely blank.
On May 3, the car company started releasing over-the-air update (OTA) to fix the issue in the 2021 and 2021 Tesla Model S and X vehicle, as well as the 2022 Model 3 and Y.
NHTSA Issues Recall Notice to Tesla Users
The National Highway Traffic Safety Administration (NHTSA) issued a recall notice that says, "During fast-charging or preparation for fast-charging, the infotainment Central Processing Unit (CPU) may not cool sufficiently to prevent higher than expected temperatures, which may cause the CPU to slow processing or restart."
Furthermore, the NHTSA said that slower processing or restarted processing could cause the center screen display to lag or appear blank.
However, the recall doesn't explain exactly how the software update will resolve it. Though it appears to have something to do with how the vehicle preconditions the battery for Supercharger use, as per The Verge report.
Engadget reported that according to the agency, a software bug can possibly cause the CPUs in those systems to overheat.
The overheating happens either when you're about to fast charge the affected models or are already in the process of fast charging it. Later on, the processor can restart or slow down when it gets too hot.
NHTSA noted that a lagging or restarting CPU may prevent drivers from using their backup cam, gear selection, windshield visibility control settings, and warning lights. Thus, increasing the risk of car crashes.
The agency said that Tesla "identified 59 warranty claims and 59 field reports" potentially related to the issues. The company, however, isn't aware of any injuries or deaths caused by it, said The Verge.

Tesla Doesn't Indicate Whether the AMD Ryzen-based Chipset Is Part of the Problem
Last year, Tesla started delivering vehicles with AMD Ryzen-based chipsets powering the infotainment system. However, Tesla did not specify whether the new processor is part of the overheating infotainment systems problem.
According to The Verge, some drivers noticed a slight decrease in driving range in cars outfitted with the Ryzen CPUs when compared to older Teslas that came with the Intel Atom earlier this year
Over the years, Tesla has issued a number of recalls, including one that it couldn't repair with an OTA update. The company recalled nearly half a million Model 3 and Model S cars last December for a malfunctioning trunk latch system.
Tesla also recalled another 579,000 cars to remove a "Boombox" feature that NHTSA took issue with.
Earlier this year, the company recalled more than 817,000 cars over faulty seat belt chimes. This latest action is among the smaller recalls Tesla has carried out recently, according to Engadget.
