The National Highway Traffic Safety Administration announced it is investigating nearly 2.6 million Tesla vehicles over a remote driving feature.

The “Actually Smart Summon” feature enables drivers to remotely summon or move their vehicles to them or another location via a mobile phone app.

The agency has previously looked into other iterations of Tesla's Summon self-driving option.

Tesla owners can move cars equipped with Actually Smart Summon, but federal regulators plan to study the feature's safety.

Tesla is under investigation by the NHTSA once again, this time over the automaker's "Actually Smart Summon" feature, which allows users to recall their Tesla to their location remotely, for example across a parking lot.

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.

The National Highway Traffic Safety Administration (NHTSA) is investigating 2.6 million Tesla vehicles due to reports of accidents related to the Smart Summon and Actually Smart Summon features.
