Tesla faces another US investigation: unexpected braking | Economic news

By TOM KRISHER, AP Auto Writer

DETROIT (AP) — U.S. auto safety regulators have launched another investigation into Tesla, this time related to complaints that its cars can stop on the roads for no apparent reason.

The government says it has received 354 complaints from owners in the past nine months about “phantom braking” in Tesla Models 3 and Y. The investigation covers around 416,000 vehicles from model years 2021 and 2022.

No accidents or injuries were reported.

The vehicles are equipped with partially automated driver assistance features such as adaptive cruise control and “autopilot”, which allow them to brake and steer into their lanes automatically.

Documents released Thursday by the National Highway Traffic Safety Administration indicate that vehicles can brake unexpectedly at highway speeds.

“Complainants report that rapid deceleration can occur without warning, and often multiple times during a single drive cycle,” the agency says.

Many owners in complaints say they are afraid of a rear-end accident on a highway.

The probe is another in a series of law enforcement efforts by the agency that include Autopilot and “Full Self-Driving” software. Despite their names, neither function can drive vehicles unattended.
