WASHINGTON — The nation's top auto safety regulator is requesting more information from Tesla Inc. to aid its investigation of certain Model 3 and Model Y vehicles equipped with Autopilot after reports alleging "phantom braking."
NHTSA's request comes after the agency in February opened the investigation into an estimated 416,000 Model 3 and Model Y vehicles from the 2021-22 model years after receiving 354 complaints of unexpected braking while using Autopilot's driver-assist features.
In a letter sent May 4 to Eddie Gates, Tesla's director of field quality, NHTSA said the number of reports of unexpected brake activation in those vehicles had increased to 758.
The agency is now seeking further details from Tesla, including any complaints or lawsuits related to the alleged defect as well as reports involving a crash, injury or death.
Tesla has until June 20 to respond, or it could face civil penalties of up to nearly $115 million.
