Stalled Transformation: Has the Heartland of U.S. Manufacturing Become an "Investment Trap" for Foreign Companies?

Does AI · Could Policy Uncertainty Be Worsening Investment Risks in the Heartland of Manufacturing?

【Text / The Observer Network Zhang Jiadong Editor / Gao Xin】

In St. Clair, Michigan, a few years ago, an electric vehicle order once helped supply-chain giant Magna see a new growth curve. Under the order agreement at the time, the company would provide battery enclosures for General Motors’ electric pickup trucks and invest hundreds of millions of dollars to build a new factory on a cornfield, aiming to secure a key position in the U.S. electrification wave.

But five years later, this factory, spanning more than a million square feet, has largely been idle and has continued to run at a loss—an example of the industry’s violent fluctuations. Similar projects are not uncommon in the United States. As demand for electric vehicles cools, parts and battery factories in many places have either suspended operations or are running at low capacity.

Most of these projects are concentrated in the traditional manufacturing regions of the American Midwest—from Michigan and Ohio to Indiana. These areas, which once flourished during the boom of the gasoline-vehicle industry and later declined as production moved offshore, were once regarded as “reindustrialization” exemplars for America’s electrification transition.

Under the policy subsidies and capital push of the Biden administration, large numbers of battery, e-drive, and full-vehicle projects have been rolled out in dense succession.

However, as the market cools and policies shift, these regions are now facing an awkward “second stall”: the new industries have not yet firmly established themselves, while employment support from the old industries has already been weakened. Some local governments previously offered large tax breaks and infrastructure investments to secure project rollouts, but now they must confront the reality of idle plants and failed fiscal returns.

St. Clair’s experience is a snapshot of this trend.

According to a recent report by The Wall Street Journal, General Motors has announced it will suspend production of large electric pickup trucks in Detroit, directly hitting Magna’s orders. Magna CEO Swami Kotagiri said the industry’s “uncertainty is unprecedented,” and that for the St. Clair plant to return to profitability, it may still take 18–24 months to find new customers and demand.

A sharp shift in the policy environment has further magnified this uncertainty. Within just one year of Trump’s second term, the U.S. government canceled a $7,500 electric vehicle tax credit and loosened fuel-economy and emissions requirements, causing automakers to clearly “apply the brakes” on their electrification path.

Over the past year, Ford has paused production of the electric F-150 and instead stepped up hybrid offerings. Meanwhile, General Motors, while “sticking” to an electric route, has cut capacity significantly to respond to demand declines.

Market data confirms this trend. Data from the industry organization Automotive Innovation Alliance shows that the share of U.S. electric-vehicle sales fell from 9.6% in 2025 to 6.5% over the past three months, reaching a new low since 2022. J.D. Power also expects overall vehicle sales to continue weakening, and that the electric-vehicle share is unlikely to rebound in the short term.

However, in sharp contrast to domestic automakers’ plant shutdowns and investment pullbacks, overseas automakers have not “retreated” from the product side.

At the 2026 New York Auto Show held on April 1, several mainstream manufacturers continued to roll out new electric vehicles in dense succession. Kia announced it will launch a lower-priced EV3 in the United States within the year; Subaru released the three-row electric SUV “Getaway,” further expanding its lineup of electric products.

This contrast—“cooling markets, adding products”—is especially striking in the Midwestern manufacturing heartland. On the one hand, there are continuously updated electrification blueprints on display at booths; on the other, there is the reality of idle factories, workers leaving, and local finances coming under pressure.

Executives’ statements also show a split. On one hand, Nissan’s head for North America said bluntly, “Demand for electric vehicles has disappeared,” believing the current market size depends largely on subsidies. On the other hand, Hyundai has observed that electric-vehicle sales in places such as California have shown signs of recovery amid rising oil prices, emphasizing that this is “market-driven rather than policy-driven.”

Kia has put forward what appears to be a long-term judgment. It believes the U.S. electric-vehicle market is likely to resume growth in the next three to four years, but the pace will be noticeably slower than previously expected. Toyota plans to keep launching new electric vehicle models while betting on demand recovery driven by fluctuations in oil prices.

This means that in the gap between short-term realities and long-term expectations, U.S. automakers are going through a period of deep “tug-of-war”:

On the one hand, idle factories, a shrinking supply chain, and reduced investment; on the other, product plans that continue to move forward and electrification technology routes that have not been abandoned.

Including parts companies such as Denso and BorgWarner, layoffs and factory closures have already begun. The Atlas Public Policy Institute notes that in the past year, more than $20 billion in electric-vehicle-related investment in the United States has been canceled.

For small and medium-sized suppliers, the impact is even more direct: investments in initial production lines are difficult to recoup, and once automakers cut projects, suppliers can only passively bear the losses.

In St. Clair, local authorities once offered tax incentives and infrastructure support to attract Magna to set up operations there, but now they must face fiscal pressure caused by idle plants. Mayor Bill Seida said bluntly that the biggest uncertainty lies in “when new industries will fill the gap.”

Even greater uncertainty comes from the policy cycle itself. What local governments and automakers cannot be sure of is whether, if the U.S. government once again turns to support electric vehicles in the future, the currently reduced capacity and supply chain—after the recent cutbacks—might face another expensive “second reconstruction.”

In related reports from foreign media, Magna is still trying to find new ways for this factory and improve production flexibility to adapt to different powertrains. Kotagiri said about 80% of the company’s products can be used across different power types to hedge against route-change risks. Regarding potential uncertainty, he said, “No one has a crystal ball.”

In the middle of the electrification transition, this Midwestern U.S. manufacturing region that once hoped for a “green revival” is stuck between the fractures of old and new cycles—neither fully escaping the shadow of traditional industry nor yet truly experiencing the assured growth of the electric era.
