The probe covers an estimated 280,000 vehicles. Five drivers alleged in complaints they couldn't steer the vehicles at all. Seven more cited a loss of power steering that required increased steering effort.
There was one report of a crash but no complaints of any injuries.
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 sixth 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, emergency braking for no reason, suspension failures, steering wheels that can fall off, and front seat belts that may not be connected properly.
Messages were left Tuesday seeking comment from Tesla.

Oracle co-founder Larry Ellison wrested the title of the world’s richest man from longtime holder Elon Musk early Wednesday as stock in his software giant rocketed more than a third in a stunning few minutes of trading. That is according to wealth tracker Bloomberg. A college dropout, the 81-year-old Ellison is now worth $393 billion, Bloomberg says, several billion more than Musk, who had been the world’s richest for four years. The switch in the ranking came after a blockbuster earnings report from Oracle. Forbes still has Musk as the richest, however, valuing his private businesses much higher.
