Tesla is recalling 130,000 cars over an issue that caused the CPU in vehicle infotainment systems to overheat during fast charging, potentially causing the car’s touchscreen to malfunction or go blank (via The Associated Press† The electric-car maker began rolling out an over-the-air update (OTA) on May 3 to resolve the issue on affected vehicles, including the 2022 Model 3 and Y, as well as the 2021 and 2022 Model X and s.

“During fast charging or preparing for fast charging, the central processing unit (“CPU”) of the infotainment system may not cool down enough to prevent the temperature from rising higher than expected, causing the CPU to slow down or restart processing. start,” the spokesperson said. recall notice of the National Highway Traffic Safety Administration (NHTSA). “Slower processing or restarted processing may cause the display on the center screen to lag or appear blank.” The recall doesn’t explain exactly what caused the problem or how the software update will fix it, but it seems to have something to do with how the vehicle battery conditions for Supercharger use.

As noted by the NHTSA, this issue could prevent drivers from using their backup camera, shifting through the touchscreen and adjusting the speed of their wipers (some Tesla models adjust wiper speeds automatically and only have manual speed controls in the central touch screen) . While it’s not clear how widespread the problem is, NHTSA says Tesla has “identified 59 warranty claims and 59 field reports” that may be related to the issue and the company is not aware of any injuries or deaths caused as a result.

Tesla started shipping vehicles with AMD Ryzen-based chipsets powering the infotainment system last year, but Tesla isn’t specifying whether the new processor is part of the problem. Earlier this year, some drivers noticed a slight decrease in driving range in cars equipped with the Ryzen CPUs compared to older Teslas that shipped with the Intel Atom.

Tesla has made a number of recalls over the years, including one that it failed to fix with an OTA update — last December, the company recalled nearly half a million Model 3 and Model S cars due to a faulty trunk locking system. More recently, Tesla recalled another 579,000 cars to remove a “Boombox” feature that the NHTSA struggled with.
