Tesla didn’t respond to a request for comment on letters NHTSA sent to the company on Oct. 12 and released on its website Wednesday. The agency’s chief counsel and head of the vehicle defects division gave the carmaker until Nov. 1 to respond to several requests, including for the company to:
- State whether Tesla intends to file a safety recall, and if not, provide technical and legal justification.
- Hand over internal investigations and studies that led to the over-the-air update.
- Share its assessment of whether the changes could have prevented a dozen crashes since 2018, five of which occurred this year.
NHTSA has the authority to deem Autopilot defective, order a recall and force Tesla to make changes to the system’s hardware or software. The agency investigated Autopilot once before after a fatal May 2016 crash but cleared the company in January 2017.
Since conducting its own investigation of that crash, the National Transportation Safety Board has repeatedly recommended that Tesla improve the measures used to monitor whether drivers are staying engaged when using Autopilot. Tesla has largely used torque sensors to detect whether drivers are keeping their hands on the wheel. General Motors Co.’s Super Cruise, by contrast, uses an infrared camera to ensure drivers’ eyes are on the road.
Following Tesla’s software update and NHTSA’s pressure on the company, Consumer Reports is homing in on the driver-monitoring issue. The independent nonprofit has both praised the ability of Autopilot to detect and respond to objects and warned that its performance could lull drivers into over-relying on a system that isn’t fully autonomous.
“The most important change Tesla needs to make is to add safeguards — such as an effective direct driver monitoring system — to ensure the driver is aware of their surroundings and able to take over,” Kelly Funkhouser, head of connected and automated vehicle testing for Consumer Reports, said on the organization’s website.
Friedman said Tesla could face fines under a section of federal law that requires carmakers to notify regulators of known defects within five days of becoming aware of them.
Jason Levine, executive director of the Center for Auto Safety, said NHTSA’s latest move “recognizes the need for significant and active enforcement when manufacturers address vehicle safety issues using software updates of any kind, especially those sent over-the-air.”
“Absent vigilant government oversight, companies like Tesla will be tempted to hide problems in overnight downloads, rather than allowing regulators and consumers to fully examine proposed repairs in the light of day,” he said.
Tesla has framed its over-the-air updates differently.
Martin Viecha, Tesla’s investor relations chief, published a tweet lauding the company’s software changes on the same day the carmaker received the letters from NHTSA.
“Thanks to mass collection of collision data, our team was able to take passive safety to a whole new level – using an OTA update,” Viecha wrote. “Hats off to our safety team!”
