“NHTSA is aware of the consumer complaint in question and is in communication with the manufacturer to gather additional information,” an NHTSA spokesperson told Reuters on Friday.
Tesla did not immediately comment.
Earlier this month, Tesla recalled nearly 12,000 U.S. vehicles because of a communication error that could trigger a false collision warning or unexpected automatic emergency brake.
The recall was prompted after a software update to vehicles with FSD Beta. Tesla said more than 99.8 percent of the vehicles recalled as of Oct. 29 had installed a software update to address the issue and no further action was necessary.
FSD is an advanced driver-assistance system that handles some driving tasks but Tesla says does not make vehicles completely autonomous. The features “require a fully attentive driver,” it says.
Last month, NHTSA raised concerns about how FSD was being used. “Despite Tesla’s characterization of FSD as ‘beta,’ it is capable of and is being used on public roads,” NHTSA said.
NHTSA in August opened a formal safety probe into Tesla’s Autopilot, a different driver assistance software system, after a dozen crashes involving Tesla models and emergency vehicles.
