Tesla has a recall involving the entire lineup because an overheated CPU can temporarily disable many important functions.
The problem was first noticed on December 23, 2021, during routine high-temperature operation tolerance testing, according to National Highway Traffic Safety Administration (NHTSA) documents. After an investigation, Tesla discovered that the Central Processing Unit (CPU) for infotainment systems may not be cold enough to prepare for fast-charging or fast-charging.
On January 3, a customer brought their 2021 Model S for service due to the CPU overheating which caused the infotainment display to reboot while the car was supercharging. The CPU was replaced but more customers followed in January.

It was later found that several vehicles were prone to this condition, which caused the infotainment CPU to slow down and the screen to lag, restart or show blank.
This is of particular concern to the NHTSA because many of the systems that Tesla needs are operated through that screen. In addition to not displaying the rearview camera when the screen is blank, both the gear that the driver wants to be in and the windshield wiper controls are restricted are crucial to using the car safely.
The list includes about 130,000 cars
In all, 129,960 Tesla cars were included in the recall, although the automaker expects only one percent of them to be faulty. These include Model Year 2021-2022 Model Ss made between February 3, 2021 and April 28, 2022; Model Year 2022 Model 3s made between December 8, 2021 and May 2, 2022; Model years 2021-2022 Model Xs were made between June 8, 2021 and April 30, 2022; And finally, Model Year 2022 Model Ys was created between October 18, 2021 and May 2, 2022.
To address this issue, Tesla Infotainment has launched an over-the-air firmware update from May 3 to improve the CPU’s temperature management. The car manufacturer believes that if the car is fast charging or preparing to charge fast, it will reduce the temperature.
