The U.S National Highway Traffic Safety Administration (NHTSA) reported Tesla Inc. having recalled over 12,000 U.S. vehicles sold since 2017.

The move by the road safety comes due to a communication error in the vehicles that may cause a false forward-collision warning or unexpected activation of the emergency brakes.

According to the automaker, it has recalled 11,704 Model S, X, 3, and Y vehicles that were prompted after a software update on Oct. 23. And also the vehicles in its limited early access version 10.3 Full-Self Driving (FSD) (Beta) population.

NHTSA commented that Tesla after receiving reports of inadvertent activation of the automatic emergency braking system has uninstalled FSD 10.3 and then updated the software and released FSD version 10.3.1 to those affected vehicles.

Last month, NHTSA had asked Tesla why it had not issued a recall to address software updates made to its Autopilot driver-assistance system to improve the vehicles’ ability to detect emergency vehicles.

According to Tesla, the issue pointed out by the agency was prompted by a software communication disconnect between two onboard chips that prompted an issue, that could produce negative object velocity detections when other vehicles are present.

The car company also said that the automatic emergency braking system unexpectedly activates while driving, and could raise the risk of a rear-end collision. However, it was not aware of any crashes or injuries related to the issue.

Tesla after the Oct. 24 reports mentioned canceling the FSD update on vehicles that had not installed it and disabled FCW and AEB on affected vehicles.

The company on Oct. 25 began deploying the over-the-air software update and re-enabled FCW and AEB features on vehicles with the update.

The U.S. auto agency in August opened a formal safety probe into the carmaker’s Autopilot system after a series of crashes involving Tesla models and emergency vehicles, for about 765,000 U.S. vehicles.

The agency in October had also questioned the car company about its “Autosteer on City Streets” which the latter also refers to as FSD first leased in October 2020. It has raised concerns about limits on disclosure by drivers of safety issues.
