Tesla has recalled more than 11,700 cars sold in the US since 2017 due to a self-driving software issue that could activate the emergency brakes unexpectedly, the National Highway Traffic Safety Administration said Tuesday.

According to a filing with NHTSA, Tesla stated that the recall of 11,704 Model S and X, 3 or Y vehicles was the result of a software upgrade issued on Oct. 23, to users who were enrolled in its limited early-access FSD program.

According to the filing, the communication error could also result in a false forward collision warning.

Tesla began receiving reports about the issue shortly after the software was released, the company claimed.

However, the electric carmaker insisted it is “not aware of any crashes or injuries related to this condition.”

Elon Musk, CEO of Tesla, was also present. tweeted about the software, saying, “Seeing some issues with 10.3, so rolling back to 10.2 temporarily. Please note, this is to be expected with beta software.”

Tesla began to distribute a software patch for all affected cars on October 25, to fix the issue.

The NHTSA said it “will continue its conversations with Tesla to ensure that any safety defect is promptly acknowledged and addressed.”

As of Oct. 29, more than 99.8 percent of affected cars — or all but 17 — had installed an update to resolve the issue.

The recall comes after the NHTSA last month asked Tesla why it didn’t issue a recall of its “Autopilot” feature after a series of deadly crashes with emergency vehicles.

The regulator also said it’s investigating the company’s requirement that “full self driving” testers sign non-disclosure agreements.
