Tesla has voluntarily recalled nearly 11,704 vehicles after identifying a software error that could cause a false forward collision warning or an unexpected activation of the automatic emergency braking system, the National Highway Traffic and Safety Administration said.
All affected vehicles had early access to the automaker’s “Full Self-Driving Beta”, an advanced driver assistance system. The system, which is still in beta mode and requires the driver to be attentive at all times, has been offered to thousands of customers in recent weeks. Tesla said he was not aware of any accidents or injuries resulting from the software error.
The over-the-air firmware update, released on October 23, introduced what the regulator called a “software communication disconnect” between two on-board chips. The next day, Tesla said it started receiving reports from customers.
“This disconnection from communication may cause the video neural networks that run on this chip to operate less consistently than expected.” the safety recall report noted. “The inconsistency can produce negative object speed detections when other vehicles are present, which in turn can lead to false [forward-collision warnings] and [automatic emergency braking] events.”
Affected vehicles include certain Model S, Model X and Model 3 cars which were manufactured between 2017-2021 and certain Model Y models which were manufactured between 2020-2021. Tesla has released a separate live software update to address the issue, and owners will receive letters advising them of the issue and its resolution.
“Within hours, we investigated the reports and took action to mitigate any potential security risk,” Tesla said.
The formal recall is a marked departure from the California automaker’s recent interactions with the nation’s leading auto safety agency, which includes the release of a software update for a separate bug identified in its autopilot system on the month. last, for which Tesla has not issued a recall. NHTSA sent a letter to the automaker on October 12 asking why it had not issued a recall.
As Tesla is aware, safety law requires manufacturers of motor vehicles and motor vehicle equipment to initiate a recall by notifying NHTSA when they determine that the vehicles or equipment they are they produced contain defects related to motor vehicle safety or do not comply with an applicable motor vehicle safety standard, “the agency wrote.
The regulator opened a separate autopilot investigation in August after identifying 12 separate incidents in which a Tesla crashed into parked emergency vehicles.
Regarding the recall, NHTSA said it would “continue conversations with Tesla to ensure any safety flaws are quickly recognized and addressed.”
