The auto safety regulator said Tesla's 2021 recall of almost 135,000 vehicles appears to address the risk presented by the failure of a media control unit and will continue to monitor the effectiveness of the callback.

Tesla agreed to the recall to address touchscreen failures under pressure from NHTSA, after the agency sought the callback in a formal letter. Automakers usually agree to voluntary fixes before the auto safety agency formally seeks a recall.

The agency said touchscreen failures posed significant safety issues, including the loss of rearview or backup camera images, exterior turn-signal lighting, and windshield defogging and defrosting systems that "may decrease the driver’s visibility in inclement weather."
