Tesla Recalls Nearly 12,000 US Vehicles Over FSD Bug That Causes False Collision Warning

Tesla has recalled nearly 12,000 vehicles sold in the US since 2017 because a communication failure could result in a false head-on collision warning or unexpected emergency brake activation, the National Highway Traffic Safety Administration (NHTSA) said Tuesday.

The California-based automaker said 11,704 S, X, 3 and Y models were downloaded in version 10.3 with Full Self-Driving (FSD) (Beta) following a software update on Oct. 23.

The FSD is an advanced driver assistance system that performs some driving tasks, but Tesla says the vehicles will not become autonomous.

NHTSA said Tesla “uninstalled FSD 10.3 after receiving reports that the automatic emergency stop system was activated by mistake” and then “updated the software and released FSD version 10.3.1 for the affected vehicles”.

The agency said it would “continue negotiations with Tesla to ensure that any security vulnerabilities are identified and resolved quickly”.

NHTSA asked Tesla last month why it wasn’t downloaded to warn them of a software update for the autopilot driver assistance system to improve the vehicle’s ability to recognize emergency vehicles.

Tesla said the problem was caused by a software communication disconnection between the two on-board chips, which could lead to “negative speed detection of objects in other vehicles.”

If the automatic emergency stop system activates unexpectedly while driving, it could increase the risk of a rear-end collision, Tesla said, but is not aware of any accidents or injuries associated with the problem.

According to an October 24 report, Tesla canceled FSD updates for vehicles it had not yet installed and disabled FCW and AEB on affected vehicles.

On the same day, Tesla CEO Elon Musk tweeted to FSD: “10.3 appears to be having some issues, so will temporarily revert to 10.2. Please note that this is expected with beta software.”

On October 25, Tesla began providing a free software update and re-enabled FCW and AEB vehicle functionality with the update.

Tesla said that as of October 29, more than 99.8 percent of vehicles — all but 17 — had the update installed and no further action was required.

NHTSA opened a formal safety test of Tesla’s autopilot system on 765,000 vehicles in the United States in August after a series of accidents involving Tesla models and ambulances.

United States of America. The Auto Safety Agency asked Tesla in October about “AutoSteer on City Streets,” which the company also referred to as FSD in its first lease in October 2020, and expressed concern about limiting the detection of safety issues by drivers.
