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

The National Highway Traffic Safety Administration has launched an investigation into crashes It said occurred while Tesla vehicles were operating with a parking feature that allows owners to summon a car from a parking space without anyone being in the vehicle.

The investigation into the summons feature likely comes as a blow to Tesla, which has been trying to advance its driverless capabilities lately. In a somewhat controversial move, Tesla's summons feature relies on a camera-only approach, as opposed to competitors using lidar, radar and cameras for driverless capabilities.

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.

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.
