The National Highway Traffic Safety Administration is probing about 2.6 million Teslas after regulators discovered that a feature on multiple vehicle models was tied to crashes. The feature, known as "Actually Smart Summon" is intended to have the car park itself and pick up its owner using a button on the Tesla app.

U.S. regulators on Tuesday announced an investigation into 2.6 million Tesla vehicles following reports of crashes linked to technology that enables drivers to use a smartphone app to remotely summon their cars or direct them to another location.
