The agency says in a document posted Tuesday on its website that loss of steering control can be accompanied by messages to drivers indicating that the power steering assist has been reduced or disabled.
The document says investigators will look into how often the problem happens, manufacturing processes and the severity of the problem.
The probe is at least the fifth started by the agency into Tesla vehicles in the past three years. Investigators are looking into Teslas that can crash into parked emergency vehicles while running on the Autopilot partially automated driving system, suspension failures, steering wheels that can fall off, and front seat belts that may not be connected properly.
