The US has opened a formal investigation into a report that Tesla vehicles allow people to play video games on a center touch screen while they are driving.
The investigation by the National Highway Traffic Safety Administration covers about 580,000 electric cars and SUVs from model years 2017 through 2022.
The NHTSA documents do not list any crashes or injuries caused by the problem.
Tesla has not commented.
An investigation can lead to a recall.
Tesla vehicle owner Vince Patton, who lives near Portland, Oregon, filed the complaint with the agency last month. In August, he was watching a YouTube video of a Tesla owner who discovered that he could now play a video game on his touch-screen while the vehicle is moving.
He tried Solitaire, too, and was able to activate that game while driving. Later, he found he could browse the internet while his car was moving.
Earlier in December, Mercedes-Benz issued a recall for a similar issue caused by a computer configuration error, raising questions about whether Tesla was being allowed to do something that other automakers are not. Most automakers disable front touch screens while vehicles are moving.
Meanwhile, The NHTSA in August began investigating 765,000 Tesla vehicles over its driver-assistance system Autopilot after a series of crashes involving the system and parked emergency vehicles.
