Toyota plans to spend $3.6 billion to shift Tacoma pickup production from Mexico to San Antonio, and General Motors has committed $4 billion to plants in Michigan, Kansas and Tennessee — but analysts count the tariff-driven US manufacturing revival as, at best, incremental.

President Donald Trump has claimed a "roaring comeback" in American auto manufacturing following his aggressive trade policy, including a 25-percent levy on imported autos. Since his return to the White House, GM, Toyota, Ford and other carmakers have announced plans to expand US plants or move production from overseas into underutilized factories. Yet the gains look modest against the scale of the industry, and trade uncertainty has dragged on spending elsewhere.

"It's a partial win," Stephanie Brinley, an automotive analyst at Mobility Global, said of the lift tariffs have given the US auto industry.

What do the numbers show?

US auto employment tells a mixed story. After falling for much of 2025, employment has climbed through most of 2026. In September, the sector employed just under 1.8 million workers, according to the US Bureau of Labor Statistics.

That is almost one percent above the level of January 2025, when Trump took office, but more than two percent below the decade's peak in July 2024, under President Joe Biden.

Production has been broadly flat. Global Mobility projects US output at 10 million vehicles in 2026 — about the same as last year — rising to around 11.3 million in 2030, when the GM and Toyota investments come into force.

"There is definitely an increase in there and it is partially related to tariffs," Brinley said, noting automakers are reconfiguring plants or using underutilized capacity rather than breaking ground at scale.

Why are suppliers hurting?

The supplier sector — which employs some 930,000 people in the United States — has absorbed the sharpest damage. Investment by suppliers plunged from more than $8 billion in the first quarter of 2025 to around $600 million across the two subsequent quarters before recovering somewhat, according to data from the Center for Automotive Research.

There has been "a noticeable slowdown" in supplier investment due to policy uncertainty, including on tariffs, said Tyler Harp, an industry economist at CAR.

"Suppliers are more exposed to tariffs," Harp said. "They're not in a position to absorb them as well as automakers."

Surveys from MEMA, the Vehicle Suppliers Association, rank changes in government trade policy as the industry's "greatest threat" over the next 12 months. In the most recent report, nearly 80 percent of companies placed trade policy changes among their four top threats, alongside US economic weakness, an external "black swan" event, and poor vehicle sales.

The industry has recovered only about half of its tariff-policy-related costs — a "sustained margin drag that is likely to weigh on supplier financials," according to a Deloitte commentary accompanying the survey. Deloitte said the industry is following a "discipline-over-growth playbook" while shifting more investment toward automation and robotics.

What about the USMCA cloud?

Experts point to the unsettled nature of Trump's trade measures as the main brake on bigger wins. The dust-up between the United States and Canada has clouded prospects for the USMCA, the North American trade agreement.

In August, a top Honda executive said the company was operating near full capacity at its North American facilities and wanted to build a new plant, but might pivot if the fog around the USMCA persists.

Trump's reversals of US policies favoring electric vehicles have added further disruption for suppliers planning parts and technology programs.

Brinley cautioned against reading plant decisions as pure tariff responses. A brand-new plant such as the one floated by Honda must run for decades.

"Plants aren't put in the ground with the expectation of lasting a presidential cycle," Brinley said. "The tariffs have an impact, but it's just not the only input."

What to watch next

Watch the November mid-term elections, which Republican allies frame as a referendum on the trade agenda. Track whether Honda commits to a new North American plant or pivots away — a clear signal on how the USMCA dispute is being priced in. On capacity, the milestone dates sit around 2030, when GM's $4 billion program and Toyota's $3.6 billion Tacoma relocation begin lifting production toward the projected 11.3 million units.
