Tesla will be contacting the owners of certain 2021-2022 Tesla model vehicles because of a problem that could cause the infotainment central processing unit (CPU) to malfunction.
The vehicles affected by this problem include:
|2022 Tesla Model 3|
|2021-2022 Tesla Model S|
|2021-2022 Tesla Model X|
|2022 Tesla Model Y|
In December 2021 during routine High Temperature Operation Endurance (HTOE) testing on the Model 3 and Model Y vehicle platform central processing unit (CPU), throttling was detected from thermal protections being engaged. An investigation into thermal management was initiated using vehicle alerts to follow the condition in the field. During this time, Tesla Engineering worked on a series of test experiments to identify the potential cause of the overheating condition. In April 2022, Tesla completed its investigation and confirmed the suspected root cause and affected vehicle population. The findings were reviewed and a recall was initiated.
According to the defect report, during fast-charging or preparation for fast-charging, the infotainment CPU may not cool sufficiently. Higher than expected temperatures could cause the CPU to slow processing or restart, and a lagging or blank center screen display. The problem could cause the rear-view camera display, windshield visibility control settings, drive modes (i.e., Drive, Neutral, or Reverse), and telltales to be unavailable.
On May 3, 2022, Tesla began deploying an OTA firmware update that will improve the management of the CPU temperature and associated communications with elevated temperature operation. This remedy will mitigate temperature elevations in the CPU when the vehicle is fast-charging or preparing to fast-charge, which will prevent slow processing or restart. Tesla’s number for this recall is SB-22-00-009 and the NHTSA campaign number is 22V-296.
