The National Highway Traffic Safety Administration has closed its investigation into Tesla's "Actually Smart Summon" feature, which allows drivers to remotely move their vehicles using a smartphone app.

The federal safety agency cited the low frequency and severity of reported crashes involving the feature as the primary reason for ending the probe. Tesla has also implemented software updates that address safety concerns identified during the investigation.

The Summon feature enables Tesla owners to call their vehicles from parking spaces or have them navigate short distances without a driver inside. NHTSA launched the investigation after receiving reports of incidents involving the autonomous driving capability.

Meanwhile, Tesla reported strong sales performance in South Korea, with March deliveries reaching 11,134 vehicles, representing an increase of more than 300% compared to the same period last year. The surge reflects growing international demand for electric vehicles.

The broader electric vehicle market has shown mixed signals, with used EV sales experiencing growth as consumers seek more affordable options amid rising gas prices. However, the new car market has faced challenges as buyers increasingly look for deals in the pre-owned segment.
