U.S. regulators have demanded Tesla recall 158,000 of its electric cars over safety concerns.
The National Highway Traffic Safety Administration asked Tesla on Wednesday (January 13) to bring in the Model S and Model X vehicles.
Regulators found that the cars' media control units could fail after years of use, leading to touch screens not working.
This would affect safety functions such as defogging, back-up cameras and the driver assistance system.
The agency said that during a review - "Tesla provided confirmation that all units will inevitably fail given the memory device's finite storage capacity."
It is unusual for the agency to formally demand a recall.
Tesla did not immediately respond to a request for comment.
But it has until January 27 to respond to the auto safety agency.
If Tesla does not agree to the recall it must provide a full explanation for its decision.
Though small by number, the action represents a relatively large recall for Tesla, which has far fewer cars on the road than other automakers.
The company delivered almost half a million vehicles last year which was above Wall Street estimates.
Tesla's stock has surged over 700% in the past 12 months, as investors bet on an electric car future.
Last week, CEO Elon Musk surpassed Amazon's top boss Jeff Bezos to become the world's richest person.
