The U.S. auto safety regulator said on the 17th (local time) that it would launch an official investigation after consumer complaints that a Tesla electric car suddenly brakes for no reason.
According to the Associated Press, the National Highway Traffic Safety Administration (NHTSA) is conducting a survey of 416,000 Tesla cars between 2021 and 2022 models.
In the past nine months, NHTSA has received 354 complaints of unexpected sudden braking on Tesla's Model 3 sedan and Model Y SUV.
These vehicles, for which consumer complaints have been raised, are equipped with autonomous driving assistance functions such as Autopilot.
Citing consumer complaints, the NHTSA warned that a Tesla car could brake hard on the highway for no reason.
According to the agency, Tesla owners have experienced repeated rapid deceleration without prior warning and were concerned about a collision on the highway.
This is the fourth time US safety regulators have launched an investigation into a Tesla car in the last three years.
The NHTSA is currently investigating an accident involving a Tesla vehicle equipped with Autopilot.
Previously, Tesla had several recalls this month.
On the 1st, 54,000 vehicles were recalled and inspected due to a defect in the fully autonomous driving (FSD) software, one of the driver assistance functions. .
