US lawmakers urged the Pentagon to bar Internet-connected vehicles with Chinese technology from entering US military bases, building on a Biden administration probe into security risks posed by the cars.

The group from the House Select Committee on China outlined their concerns in a letter Thursday to Defense Secretary Lloyd Austin, citing a Commerce Department investigation, which could result in a ban on transactions involving certain Chinese vehicle technology in the US — and by extension, the cars, including electric vehicles that use banned components. The authors cite potential data and cyber-security risks posed by so-called connected vehicles that capture massive amounts of personal data.
