Tesla’s controversial “Full Self-Driving” feature took another hit on Tuesday. The Texan automaker issued a recall for nearly 12, 000 vehicles after an over-the-air software update introduced a new bug that can cause false activations of the cars’ forward collision warning and automatic emergency braking (AEB) systems.

According to the safety recall report , the problem affects Models S, X, and 3 vehicles built between 2017 and 2021 and Model Y vehicles built between 2020 and 2021 that are running firmware release 2021. 36. 5. 2 . The updated firmware was rolled out to drivers in its beta testing program on October 23 and, once installed, caused a pair of chips to stop talking to each other when the vehicle wakes up from “sentry mode” or “summon standby mode. ”

That error prevents the neural networks that operate on one of the chips from running consistently, causing it to throw false-positive collision warnings and—more seriously—false-positive AEB activations.
