For car shoppers looking for a luxury three-row crossover S.U.V., the Galaxy M9 checks all the boxes: It has heated and massaging leather seats throughout, a 30-inch highly customizable video display and dual phone chargers.

A plug-in hybrid, the M9 can drive about 110 miles on battery alone. Combine that with the gasoline engine and the M9 can cover a whopping 660 miles.

The price for this top-of-the-line trim: an eye-popping $35,000. That’s if you’re in China. Made by Geely, this smooth-riding, driver-pampering crossover The New York Times tested for 10 days in February would cost more than twice that from any brand with an American showroom. Geely, founded in China just 28 years ago, now sells almost as many vehicles worldwide as the 123-year-old Ford Motor Company.

And this is when you’ll be able to buy it here:

Never.

That’s the hope of the U.S. auto industry as well as the U.S. military and intelligence establishment. And it’s the goal of two senators who represent states with a heavy industry presence: Bernie Moreno, Republican of Ohio, and Elissa Slotkin, Democrat of Michigan, who have sponsored a bill to permanently ban internet-connected vehicles from China from being sold in this country. (For good measure, it lumps in cars from Iran, North Korea and Russia.)

An existing 100 percent tariff and 2027 Commerce Department restrictions on connected vehicles from China make it impractical to import Chinese vehicles today. As a result, Polestar, owned by Geely, will stop selling vehicles here in 2027. The Senate bill, which has bipartisan support and has been unanimously voted out of committee, would codify that exclusion.

And it’s wide-ranging: Under the terms of the Connected Vehicle Security Act of 2026, any vehicle manufacturer that is more than 15 percent owned by a Chinese company would not be able to sell cars in the United States. Chinese software would be banned next year, and hardware in 2030.

Mercedes-Benz, which has close to 20 percent Chinese ownership, will be unable to sell its vehicles if the bill passes, unless the company reduces that percentage, the bill’s ownership limits are changed or the company receives a waiver from the Commerce Department.

Even Canadian or Mexican residents who have legally bought a Chinese vehicle in their own country would not be allowed to drive them across the border, even for a day trip.

The senators say the bill is needed for two reasons: economic and security. Chinese vehicles cost much less, they argue, because the Chinese government gives companies cash subsidies, free land, cheap electricity and low-paid workers.

“These vehicles are massively subsidized,” said Mr. Moreno, who made his fortune building an auto dealership empire in Ohio. “Our auto jobs are good jobs; in China they’re poor jobs.”

But just as important, internet-connected vehicles present serious security concerns, the senators and auto industry officials say. To achieve self-driving capability, the vehicles take dozens of photos per second, although few of them are uploaded. With today’s cars and trucks sporting a wide array of cameras, sensors and internet connectivity, they can capture extensive data, like identifying drivers, their location and their habits, or recording in-vehicle conversations or gaining access to phone data, among other risks.

“These are surveillance tools on wheels,” said John Bozzella, chief executive of the Alliance for Automotive Innovation, the trade group representing most of the nation’s automakers and sellers. “They know where you’re going, where you’ve been and who’s in the car.”

Ms. Slotkin, a former C.I.A. agent, agreed. “All the data that these cars are collecting from our military bases, from our infrastructure sites, individual information on a senior leader and where they are, all of that is being sent back to Beijing,” she said.

A high-ranking Geely executive, who spoke on the condition of anonymity owing to the political sensitivities involved, insisted the company would work within U.S. laws. “We will strictly comply with the laws and regulations in each market,” the executive said. “Not only safety and quality but also data privacy. Everything.”

The senators also insist that Chinese companies have unreasonable advantages. China “is subsidizing their cars for the specific intent of underselling all the other vehicles in a market to put them out of business,” Ms. Slotkin said.

“That’s 450,000 workers in my state alone who are connected to the auto industry,” she added. “So it’s a huge economic security issue.”

RJ Scaringe, chief of the American E.V. company Rivian Automotive, backs this up. “There’s a very real difference in the input costs necessary to build vehicles in China,” he said. “There’s no way for us to easily have that input cost structure.”
