Tesla calling back 130,000 EVs to patch AMD Ryzen APUs overheating issue

According to a report by electric, Tesla issued a soft recall for around 130,000 of its cars due to an overheating issue with the onboard CPU. Overheating might cause problems with the infotainment touchscreen. This type of recall, thankfully, does not require owners to return their vehicles to the dealer, and a repair will be provided via an over-the-air software update.

The 2021-2022 Model X and Model S, as well as the 2022 Model 3 and Model Y, are all affected because they use AMD’s Ryzen APUs. Because of their lower TDP, older Teslas with Intel Atom CPUs appear to be unaffected. The NHTSA (National Highway Traffic Safety Administration) has ordered Tesla to initiate a recall because the flaw could compromise the car’s vital functions.

According to the research, the overheating problem occurs when the car’s battery is pre-conditioning when traveling to a Supercharging station or while parked during a fast charge. The issue is that the car’s liquid cooling will be directed to the batteries, causing the CPU to overheat.

This is what the recall notice from Tesla read

“A lagging or restarting CPU may prevent the center screen from displaying the rearview camera image, gear selection, windshield visibility control settings, and warning lights, increasing the risk of a crash.”

Overheating can slow down and, in some situations, turn off the vehicle’s infotainment touch screen (the same one that plays video games). Tesla detected the problem during standard endurance testing, according to the Associated Press, and there have been no reports of collisions or injuries. This is Tesa’s eleventh recall since January 27, 2022.

Starting July 1, Tesla owners should receive a recall notice in the mail, however, the software upgrade has already begun trickling out as of last week. By the time they’re alerted, perhaps all of the impacted car owners will have already downloaded the fix to better CPU temperature management.
