DETROIT — Tesla is recalling nearly all vehicles sold in the U.S., more than 2 million, to update software and fix a defective system that’s supposed to ensure drivers are paying attention when using Autopilot.
Documents posted Wednesday by U.S. safety regulators say the update will increase warnings and alerts to drivers and even limit the areas where basic versions of Autopilot can operate.
The recall comes after a two-year investigation by the National Highway Traffic Safety Administration into a series of crashes that happened while the Autopilot partially automated driving system was in use. Some were deadly.
The agency says its investigation found Autopilot’s method of making sure that drivers are paying attention can be inadequate and can lead to “foreseeable misuse of the system.”
The added controls and alerts will “further encourage the driver to adhere to their continuous driving responsibility,” the documents said.
But safety experts said that, while the recall is a good step, it still makes the driver responsible and doesn’t fix the underlying problem that Tesla’s automated systems have with spotting and stopping for obstacles in their path.
The recall covers models Y, S, 3 and X produced between Oct. 5, 2012, and Dec. 7 of this year. The update was to be sent to certain affected vehicles on Tuesday, with the rest getting it later.
Shares of Tesla slid more than 3% in earlier trading Wednesday but recovered amid a broad stock market rally to end the day up 1%.
The attempt to address the flaws in Autopilot seemed like a case of too little, too late to Dillon Angulo, who was seriously injured in 2019 crash involving a Tesla that was using the technology along a rural stretch of Florida highway where the software isn’t supposed to be deployed.
“This technology is not safe, we have to get it off the road,” said Angulo, who is suing Tesla as he recovers from injuries that included brain trauma and broken bones. “The government has to do something about it. We can’t be experimenting like this.”
Autopilot includes features called Autosteer and Traffic Aware Cruise Control, with Autosteer intended for use on limited access freeways when it’s not operating with a more sophisticated feature called Autosteer on City Streets.
The software update will limit where Autosteer can be used. “If the driver attempts to engage Autosteer when conditions are not met for engagement, the feature will alert the driver it is unavailable through visual and audible alerts, and Autosteer will not engage,” the recall documents said.
