Transportation Secretary Sean Duffy fired a pointed letter at Ford CEO Jim Farley accusing the automaker of entangling its future with Chinese state-backed enterprises, and Ford punched back hard, calling the accusations wrongheaded.
Duffy's letter, obtained by FOX Business, laid out a bill of particulars against one of America's oldest car companies. He cited Ford's use of licensed battery technology from Chinese manufacturer CATL at its BlueOval Battery Park facility in Marshall, Michigan. He flagged a joint venture with Chinese-owned Geely in Spain. He pointed to reported talks between Ford and BYD, another Chinese firm, over hybrid vehicle components. And he accused Ford of dragging its feet on bringing Lincoln production back to the United States, with reshoring of models like the Nautilus potentially delayed until 2030.
The letter did not announce any formal regulatory action. But the language left little room for ambiguity about where the Trump administration's Transportation Department stands on American companies that deepen their operational ties to Beijing.
Duffy opened the letter by telling Farley he was writing "to express the profound concern of the U.S. Department of Transportation regarding the strategic trajectory of Ford Motor Company." He argued that Ford's recent decisions "paint a troubling picture of a foundational American brand actively intertwining its future with Chinese state-backed enterprises."
The concern is not abstract. Chinese law can require companies operating in China, or partnering with Chinese firms, to provide the government access to proprietary and customer data. For a connected-vehicle manufacturer collecting location data, driving habits, and personal information from millions of Americans, that is not a hypothetical risk. It is a structural vulnerability baked into the partnership itself.
Duffy pressed the point further, writing that "when a company intentionally chooses to deepen operational dependencies on strategic competitors, it fails to act as the reliable partner the American public and this DOT require." He added that "iconic American companies, like Ford, are also expected to out-innovate competitors" and "need to chart clear paths to technological self-reliance."
That last line carries weight. Duffy was not merely scolding Ford for doing business with Chinese firms. He was challenging the company's claim that it can remain a competitive American manufacturer while licensing core battery technology from a Chinese state-adjacent supplier rather than developing it domestically.
Ford did not take the accusation quietly. The company issued a statement calling Duffy's letter "a wrongheaded attempt to capture headlines at the expense of a company that has done more for American manufacturing than virtually any other in the nation's history."
The automaker also took a swipe at Duffy's process, saying that had the secretary "reached out before issuing his letter to the press, we would have been happy to share more details about Ford's U.S. commitment." That line implied Duffy sent the letter to media outlets before, or instead of, engaging Ford directly. Duffy's office has not addressed that claim.
Ford leaned on its domestic investment record in its defense. The company described its BlueOval Battery Park in Marshall as representing billions of dollars in investment and said the facility is expected to create roughly 1,700 American jobs. Ford also characterized its arrangement with CATL as "a limited technology-licensing and services agreement, not a joint venture or foreign-owned manufacturing operation", a distinction the company clearly wants to draw in sharp terms.
The company noted that the White House itself had highlighted the Marshall battery project in a recent press release. Ford also pointed to Commerce Secretary Howard Lutnick, who praised Ford's decision to expand Lincoln production in the United States, saying the move would bring "thousands and thousands of jobs." The administration's own public messaging, in other words, had treated Ford as a success story, not a security threat.
That creates an awkward split. One cabinet secretary praises Ford's domestic expansion while another accuses the same company of selling out to Beijing. Whether that reflects genuine policy tension inside the administration or a coordinated good-cop-bad-cop strategy remains unclear.
Duffy's letter did not arrive in a vacuum. In July, the Senate Commerce, Science and Transportation Committee approved bipartisan legislation that would ban the import, sale, and operation of vehicles manufactured by companies designated as foreign entities of concern, a category that includes firms based in China. The same bill would prohibit certain connected vehicle technologies developed by those countries.
By September, the Alliance for Automotive Innovation, the industry's main trade group, urged congressional leaders to enact a permanent ban on Chinese-made vehicles in the United States. When an industry lobby group asks the government to ban its foreign competitors, the competitive pressure from China has reached a level that no one in Detroit can afford to ignore.
The broader federal posture toward Chinese involvement in American transportation infrastructure has been tightening for months. The Trump administration has taken a harder look at safety and integrity across the transportation sector, and the scrutiny of foreign entanglements fits that pattern. Connected vehicles, cars that transmit data, receive software updates, and interact with infrastructure networks, sit at the intersection of consumer technology and national security in ways that a 1990s sedan never did.
Ford's stock closed at $13.61, up 1.95 percent on the day the letter became public. Wall Street, at least for the moment, did not treat the letter as a material threat.
Ford's rebuttal hinges on a careful distinction: it licenses CATL's technology but does not operate a joint venture with the Chinese battery maker. That framing may be legally precise. But it does not address the core of Duffy's concern. If the technology itself originates from a company subject to Chinese government data-access laws, the corporate structure of the deal matters less than the data pipeline it creates.
Ford also did not directly address the reported discussions with BYD over hybrid components, nor did it explain the terms of its Geely joint venture in Spain. The company's statement focused on its domestic job creation and investment, strong ground, but not a point-by-point rebuttal of the security argument Duffy raised.
The question of the Lincoln Nautilus reshoring timeline is similarly unresolved. Duffy's letter claimed the delay could stretch to 2030. Ford did not dispute that date in its public response. A five-year horizon for bringing an American-branded luxury vehicle back from overseas production does not exactly scream urgency, especially when the administration is pressing every major manufacturer to build more in the United States.
Aviation and transportation safety have drawn increasing federal attention in recent months, from air traffic control failures at major airports to broader infrastructure accountability. The Duffy letter fits a wider pattern: the administration signaling that it expects American companies in critical sectors to reduce their exposure to adversarial foreign governments, not increase it.
Meanwhile, the federal government has also been overhauling operations at airports nationwide, reflecting a push to modernize and secure transportation systems from multiple angles. Ford's situation is different in kind but similar in principle: the government is asking whether the systems Americans depend on every day are being managed with security in mind or just with cost savings in mind.
Duffy has not indicated whether the letter will be followed by any formal investigation, rulemaking, or enforcement action. For now, it functions as a public warning, a shot across the bow from a cabinet secretary who clearly wants Ford to understand that the administration is watching.
Ford can point to its billions in domestic investment and its thousands of American jobs. Those are real. But so is the fact that the company's battery technology, its overseas joint ventures, and its component supply chains run through Beijing in ways that did not exist a decade ago. The question is whether Ford is building an American future or licensing one from a strategic rival.
When an iconic American brand needs a Chinese battery maker's permission to power its own cars, the word "independence" starts to lose its meaning.
