Ram HD production may soon shift from Mexico to the United States as tariff pressure forces Stellantis to reconsider its manufacturing strategy. The multinational automaker is currently holding preliminary discussions with suppliers to determine the feasibility and cost of relocating heavy-duty truck production to the Warren Truck Assembly Plant in Michigan. This potential move signals a significant shift in the North American automotive industry as companies navigate changing trade policies.
According to executives at involved suppliers, Stellantis is carefully studying the numbers before committing to what would be a costly retooling of its Michigan facility. The company has declined to comment on the ongoing discussions. However, the underlying reason is clear: tariffs have fundamentally changed the economics of building vehicles in Mexico or Canada for the United States market.
Why Tariffs Changed Everything
The Ram HD represents exactly the type of vehicle where manufacturing economics matter significantly. Heavy-duty trucks carry high transaction prices and generate substantial profit margins. However, their profitability in the US market depends heavily on where these vehicles are manufactured.
Currently, Ford and General Motors already build their heavy-duty trucks in the United States. This leaves Stellantis as the odd one out with the Ram brand, making the Warren facility an increasingly attractive option. The tariff calculations that once favored Mexican production have now shifted dramatically.
For Latino workers in the automotive sector on both sides of the border, these discussions carry significant implications. Understanding how U.S. citizenship naturalization works becomes increasingly relevant as manufacturing jobs potentially shift between countries.
The Warren Truck Assembly Plant Opportunity
The Warren Truck Assembly Plant presents both an opportunity and a challenge for Stellantis. The Michigan-based factory is currently described as hideously underutilized, creating a natural opening for new production programs.
Previously, the facility served as the home of the Ram 1500 Classic. Currently, it produces the Grand Wagoneer for the Jeep brand. The plant is also preparing for electrified production as the Grand Wagoneer welcomes an extended-range electric powertrain.
This extended-range system features an internal combustion engine that drives a generator, producing electricity for the high-voltage traction battery and electric drive units. A high-volume program like the Ram HD would help the plant reach maximum capacity quickly.
Historical Context: The 2018 Decision
This is not the first time Warren Truck has been considered for heavy-duty truck production. Back in 2018, Fiat Chrysler Automobiles explored this option but ultimately abandoned the plan to move production from Mexico.
At that time, keeping production in Mexico was part of the FCA group’s manufacturing strategy. The decision followed a period when US labor costs had risen sharply after difficult negotiations with the United Auto Workers union. Eventually, the company was convinced to shift more light-duty truck production instead.
Recently introduced tariffs, however, are now pushing the calculation in the opposite direction. What made sense in 2018 may no longer hold true in 2026.

Challenges Facing the Production Move
Despite the tariff incentives, a production switch of this magnitude is far from simple. Stellantis faces numerous hurdles that could complicate or delay any relocation decision.
- New tooling requirements for the Warren facility
- Supplier logistics reconfiguration across North America
- Workforce planning and training for Michigan workers
- Significant capital investments in plant upgrades
- Timeline challenges for production transitions
Moving the Ram HD from Mexico to the US will not be cheap or quick for Stellantis North America. The company must weigh these substantial costs against the tariff savings over time.
Trade Policy Uncertainty Complicates Decision
Perhaps the most significant variable hanging over this decision is the larger trade policy landscape. The future of the US-Mexico-Canada trade agreement remains uncertain, creating additional risk for any major manufacturing relocation.
Spending heavily to relocate production becomes increasingly difficult to justify when the rules governing the underlying business case can change overnight. Stellantis executives must consider whether today’s tariff environment will persist long enough to justify the investment.
For now, suppliers are simply being asked to put a price tag on the alternative of making the Ram HD in the brand’s home market. These preliminary cost assessments will inform whether Stellantis proceeds with more detailed planning.
The situation mirrors broader challenges facing the North American automotive industry as companies navigate an era of trade uncertainty. Many Latino families with connections to both US and Mexican manufacturing operations are watching these developments closely.

The automotive sector represents a crucial source of employment for Latino workers throughout North America. Whether production happens in Michigan or Mexico, these jobs support countless families and communities.
Ford and General Motors have already demonstrated that US-based heavy-duty truck production can be profitable and competitive. If Stellantis follows suit, it would represent a significant consolidation of American truck manufacturing on US soil.
The Ram brand has built a loyal following among American truck buyers, many of whom prioritize domestic manufacturing in their purchasing decisions. A move to Warren Truck could strengthen the brand’s appeal in this regard.
Stellantis continues to evaluate all options as it navigates this complex decision. The company’s supplier discussions represent an early stage in what could become a major manufacturing realignment. According to reporting from Automotive News, these conversations remain in the preliminary phase as of September 2026.
Why is Stellantis considering moving Ram HD production to the US?
Tariffs have changed the economics of building vehicles in Mexico for the US market. The heavy-duty truck segment generates significant profit margins, making the tariff impact particularly meaningful for Ram HD production.
Where would Ram HD trucks be built if production moves?
The Warren Truck Assembly Plant in Michigan is being considered for Ram HD production. The facility currently produces the Grand Wagoneer and was previously home to the Ram 1500 Classic.
Why didn’t Stellantis move production in 2018?
In 2018, Fiat Chrysler Automobiles abandoned similar plans due to rising US labor costs following difficult negotiations with the United Auto Workers. At that time, Mexican production remained part of the company’s manufacturing strategy.
What challenges does a production move present?
Relocating production requires new tooling, supplier logistics reconfiguration, workforce planning, and significant capital investments. The process is neither cheap nor quick for Stellantis North America.
When will a decision be made on Ram HD production?
Stellantis is currently in preliminary discussions with suppliers as of September 2026. No final decision has been announced, and the company continues to study the cost implications before committing.

The next phase of supplier cost assessments is expected to conclude in late 2026, at which point Stellantis leadership will have the data needed to make a formal decision on the future of Ram HD manufacturing.
