Why a Local Assembly Line Won't Save an Automotive Brand Anymore

On June 25, 2026, Polestar announced it will stop selling new vehicles in the United States starting with the 2027 model year. The decision comes after the U.S. Department of Commerce refused to grant the Swedish brand an authorization under its Connected Vehicle Rule. This rule effectively blocks any connected cars with software or hardware tied to China.

Polestar is majority-owned by Zhejiang Geely Holding Group, a massive Chinese automotive conglomerate. The federal government decided this corporate relationship is too close to ignore. Your car is now a computer on wheels, and Washington is treating it like a foreign spy.

The company builds its Polestar 3 SUV in Ridgeville, South Carolina. Local assembly lines no longer provide immunity from trade restrictions. Physical manufacturing has been eclipsed by the origins of the digital code powering the vehicle.

We are looking at a massive shift in how cars are regulated in this country. The Bureau of Industry and Security, a branch of the Commerce Department, finalized the connected vehicle regulations in January 2025. They designed the rules to target software in the 2027 model year and hardware by 2030.

The rule targets cellular modules, cameras, microphones, GPS, and automated driving software. If a foreign adversary can theoretically tap into these systems, the government wants the car off the road. They are not waiting for an actual breach to happen before they act.

Volvo Cars is also owned by Geely, but the government granted them a specific authorization to keep selling in May. Why did one brand get a pass while its sibling got the boot? I do not have a clear answer for you on that.

Volvo has built cars in America for a long time and has hundreds of dealerships. The Office of Information and Communications Technology and Services, a U.S. federal agency overseeing digital supply chains, handled their case-by-case review. They restructured their data security systems to keep driver data out of Chinese hands.

Polestar has a much smaller footprint and has been bleeding money in the American market. The brand was either too young or too deeply integrated with Geely’s Chinese engineering to make the same transition. It was simpler for them to pack up their bags.

The brand’s 32 American dealers will remain open to service cars and sell down the remaining inventory of the Polestar 3 and Polestar 4. The company is turning its focus entirely to Europe, where it currently does about 80 percent of its business. CEO Michael Lohscheller stated that the industry is entering a new phase based on regional dynamics.

Polestar actually saw 94 percent of its first-quarter sales in 2026 come from outside the United States. Losing the American market is a massive blow to their global prestige. It will not kill the brand. They plan to manufacture the upcoming Polestar 7 in Europe and continue expanding in Southeast Asia.

This leaves American buyers with fewer electric vehicle options. The Polestar 3 and Polestar 4 are highly capable machines with excellent driving dynamics. Now they are dead ends in the Western hemisphere.

Protectionism is driving a massive part of this regulatory push. The American government is determined to keep domestic brands from being wiped out by Chinese electric vehicle technology. They are using data security as a very convenient shield.

The Polestar 4 is assembled in Busan, South Korea. It runs on a Snapdragon processor and uses Android Automotive software. None of those details saved it from being labeled a national security threat due to its corporate ownership.

If you own a Polestar, do not panic about getting it serviced. The company is legally obligated to support its existing customer network. Do not expect to see a Polestar 5 or Polestar 6 on American roads anytime soon.

The lesson here is simple. Do not assume local jobs or factory investments will protect a foreign car company from geopolitics. The software under the hood is the new battleground.
