Connected Vehicle Security Act of 2026 Gains Senate Momentum

Senate Pushes Connected Vehicle Security Restrictions

The Connected Vehicle Security Act of 2026 is at the center of a bipartisan Senate effort to codify restrictions on Chinese connected-vehicle technology. Senators Elissa Slotkin, a Democrat from Michigan, and Bernie Moreno, a Republican from Ohio, introduced the measure in April. The legislation would prohibit the import, manufacture, sale, and resale of connected vehicles, as well as related software and hardware linked to China and other foreign adversaries, including through joint ventures. The Senate push came as President Donald Trump and Chinese President Xi Jinping were meeting in Washington. By September 24, the bill’s authors said they would work toward unanimous-consent passage the following week.

The legislation would give the United States Department of Commerce authority to identify and block vehicle technologies, components, and transactions considered a security threat. It also establishes enforcement mechanisms intended to prevent prohibited technologies from entering the American market. The restrictions would be phased in rather than taking effect simultaneously. Provisions covering vehicles and software are scheduled to begin in 2027, while restrictions covering hardware would follow in 2030. The structure would therefore extend the policy beyond finished vehicles to connected technologies and components that can be integrated into vehicles or supplied through business relationships.

The measure would codify an existing Biden administration regulation issued in early 2025 that restricted certain Chinese connected-vehicle technology. The proposed legislation goes beyond a narrow vehicle ban by covering software and hardware tied to China and other foreign adversaries. Supporters in the Senate have argued that connected vehicles can create data-security and national-security concerns because modern vehicles contain communications systems, sensors, software, and other networked components. The bill has also received backing from major automotive and labor organizations, although the legislation remains subject to the Senate and House legislative processes before it could become law.

Restrictions Would Extend Beyond Finished Vehicles

The legislation also comes against an existing trade backdrop that includes a 100% U.S. tariff on Chinese electric vehicles. The proposed restrictions would address a different part of the market by focusing on connected vehicles and associated technology, rather than relying solely on import duties. For automakers and suppliers operating across the United States and China, the measure could affect sourcing decisions, technology partnerships, manufacturing arrangements, and future market-entry strategies if enacted. The bill’s joint-venture provisions are particularly relevant because they would apply restrictions even where Chinese-linked technology or companies participate through a broader commercial structure.

Congressional Support and Next Steps

The Senate measure has attracted substantial congressional support. The original article reported 51 Senate supporters and more than 100 House cosponsors, while later statements from Slotkin and Moreno said the bill had broad bipartisan backing after clearing a Senate committee unanimously. The sponsors discussed the legislation on the Senate floor on September 24 and said they planned to pursue unanimous-consent passage the following week. That timeline means the immediate next step is congressional action rather than an already completed ban. The final legal effect would depend on passage through Congress and enactment.

Industry Impact & Outlook

If enacted, the measure would formalize a long-term U.S. barrier to Chinese connected-vehicle technology and could reshape how automakers manage software, components, suppliers, and joint ventures. The phased schedule would give affected companies time to adjust sourcing and technology arrangements, while the Commerce Department’s proposed authority would become important to determining which products and transactions are restricted. The issue is particularly relevant to manufacturers and suppliers with China-linked operations, because compliance would extend beyond imported vehicles to connected technologies and hardware. Congressional action will determine whether these restrictions become permanent federal law.
