The United States has Initiated an Investigation into Tesla’s “Smart Summon” Autonomous Driving Technology.

U.S. safety regulators have launched an investigation into Tesla’s feature that allows drivers to summon their parked vehicles remotely without being inside, following reports of multiple accidents related to the technology.

The National Highway Traffic Safety Administration (NHTSA) stated that Tesla vehicles operating with the “Actually Smart Summon” feature have been reported to struggle with detecting obstacles like posts and parked cars.

This feature is available in approximately 2.6 million Tesla vehicles manufactured since 2016, including the Model S, Model 3, and Model X and Y SUVs.

Tesla has yet to respond to the investigation. CEO Elon Musk has previously defended Tesla’s autonomous driving advancements, claiming they are safer than traditional driving and represent the future of transportation.

NHTSA reported at least four crashes involving the “Actually Smart Summon” feature, launched in September, which lets drivers control their cars via smartphone. Additionally, the agency is aware of around a dozen incidents involving the earlier version, “Smart Summon.” None of these incidents resulted in injuries.

This investigation is expected to renew scrutiny over Tesla’s automated driving technologies, which are also under separate NHTSA investigations due to accidents, including some fatal ones, linked to its Autopilot features.

The current probe could potentially lead to a recall. NHTSA plans to examine issues such as the speed limits of vehicles using the “Actually Smart Summon” feature and the safeguards preventing its use on public roads.

Tesla’s user manual states that “Actually Smart Summon” is intended for private, familiar areas, such as driveways, and advises maintaining a clear line of sight with the vehicle. It also specifies that the feature is disabled on public roads.

The investigation announcement comes just weeks before Donald Trump, a close ally of Elon Musk, is set to assume the presidency. Trump’s campaign included promises to significantly reduce regulations and government spending.
