The National Highway Traffic Safety Administration has opened an investigation about Tesla’s Compact Model 3 and Model Y EVs after more than 350 owners complain about sudden and unexpected brake application by the vehicle emergency system.
“The Office of Error Investigation (ODI) received 354 unsolicited allegation complaints brake activated in 2021-2022 Tesla Model 3 and Model Y cars,” NHTSA said in its documentation. “Received in the past nine months, reports are often described by consumers as ‘virtual brakes’.”
“Complainants report that rapid deceleration can occur without warning, and often repeats within a driving cycle,” the agency said.
An investigation is not a recall, but it could be the first step in the process if NHTSA determines that a customer complaint is valid and the automaker is obligated to take action. overcome. A similar problem has resulted in the recall of nearly 12,000 models across Tesla’s entire product line – including the larger Model S and Model X – by 2021.
In that case, Tesla said the systems on its vehicles failed to communicate with each other correctly, resulting in the forward collision warning and emergency braking systems automatically detecting a “false positive”. That issue is isolated to a specific Tesla software release (201.36.5.2) and resolved via an over-the-air (OTA) update.
