More Than 750 U.S. Drivers Complain vs Tesla's Phantom Braking

More than 750 Tesla owners have complained to US safety regulators that cars equipped with the automaker's semi-autonomous driving systems have unexpectedly stopped on highways, Tom Krisher reported for the Associated Press (AP).

The statistic was revealed by the National Highway Traffic Safety Administration (NHTSA) in a detailed information request letter to Tesla that was uploaded on the agency's website on Friday.
The carmaker is being asked for any consumer and field reports of false braking, as well as reports of collisions, injuries, deaths, and property damage claims, in a 14-page letter dated May 4. It also inquires as to whether the company's "Full Self Driving" and automated emergency braking technologies were operational at the time of the event.
After receiving 354 complaints, the government began looking into phantom brakes in Tesla's Models 3 and Y last February. The investigation will encompass around 416,000 automobiles from the model years 2021 and 2022.
The agency stated in February that it had received no reports of collisions or injuries. Tesla has until June 20 to answer to the information request, but the letter states it can request an extension. Tesla Inc.'s stock dropped more than 9% on Friday.
The agency claimed it was looking into vehicles with automated driver-assist systems like adaptive cruise control and "Autopilot," which allows them to automatically brake and steer within their lanes, when it announced the investigation.
The government stated that complainants note that the sudden deceleration might occur without notice and frequently throughout a single drive cycle. Many owners expressed concern in their comments about a highway rear-end collision.
NHTSA requests the beginning speed at which the automobiles began to brake, the final speed, and the average deceleration in the letter. It also wants to know if Tesla has video of the brake incidents and if the automatic systems spotted a target obstruction.
