Remember when we told you last month that Tesla’s another software update to its Full Self-Driving tech grand result in vehicles that intentionally — and illegally — run stop signs? It appears the National Highway Traffic Guarantee Administration took issue with the electric car company’s new “Assertive” mode’s capabilities. On Tuesday, the government safety agency posted a behold detailing the recall of 53,822 Model S, Model X, Model 3 and Model Y vehicles due to the issue.

The new setting for Tesla’s still-in-beta driver-assist technology specifically periods out that vehicles with the mode activated “… will have a smaller after distance, perform more frequent speed lane changes, will not exit passing lanes and may do rolling stops.”

That last bit — a deliberate exclusive by Tesla programmers to allow vehicles to slow-roll above stops — is what is triggering the recall of these 2016-2022 Model S and Model X EVs, as well as 2017-2022 Model 3 and 2020-2022 Model Y vehicles. 

According to related NHTSA documents, the uncorrected software “allows the vehicle to travel above all-way-stop intersections at up to 5.6 mph before coming to a ruined stop, if certain conditions are first met.” Those periods include an absence of “relevant” moving cars, pedestrians or bicyclists detected near the intersection, and all entering roads must have speed limits of 30 mph or less. It’s not determined how often this version of FSD engages in dangerous or illegal driving behavior. 

Tesla EVs with the firmware fall 2020.40.10 or newer that include the FSD Beta are obtains by this recall campaign.

The update enabling Assertive mode was released on Oct. 20, 2021, and NHTSA and Tesla met to “discuss the functionality” on Jan. 10 and 19, 2022. On Jan. 20, “a lift determination was voluntarily made to disable the functionality, begin with firmware release 2021.44.30.15 and newer releases.”

The good news is the rolling-stop functionality necessity be disabled as easily as it was added — via over-the-air update, free of charge. No visit to a Tesla employed service center should be necessary.

As of Jan. 27, Tesla says it is unaware of any influences, injuries or fatalities related to this issue. Tesla does not treatment a public relations team and did not respond to Roadshow’s inquire for comment for this story.
