Trump Tariffs 2025: How to Keep Auto Repairs Affordable

Introduction to Tariffs

The latest discussions around Trump tariffs have sparked major debates in the automotive and manufacturing industries. As these proposed Trump tariffs on imports take shape, experts warn of possible price hikes, supply chain disruptions, and shifting trade policies. For U.S. consumers and businesses, understanding how these tariff changes could impact vehicle prices and parts availability is more important than ever.

Tariffs are taxes levied by governments on imported or exported goods, aimed at generating revenue, protecting domestic industries, or balancing trade deficits. By increasing the cost of imported products, tariffs make domestic goods more competitive but can raise consumer prices and disrupt supply chains. In 2025, President Donald J. Trump implemented a 25% tariff on imported vehicles and critical auto parts, such as engines and transmissions, invoking national security under Section 232 of the Trade Expansion Act of 1962.

These tariffs, targeting countries like Canada and Mexico, aim to bolster U.S. manufacturing but pose significant challenges for the automotive industry, which relies heavily on integrated North American supply chains. The tariffs affect vehicle affordability, production costs, and the availability of parts, with notable implications for the used engines and transmissions market, where cost increases could limit supply and raise repair prices for consumers and businesses.

How Trump Tariffs Affect the Automotive Industry 

Trump’s 25% tariffs on imported vehicles and parts, effective April and May 2025, significantly impact the automotive industry, which employs millions and relies on integrated North American supply chains. The tariffs aim to boost U.S. manufacturing but introduce challenges across three key areas:

Manufacturing Costs Increase: The tariffs add substantial costs, with the Center for Automotive Research estimating a $108 billion burden on U.S. automakers in 2025. Imported vehicles face an average cost increase of $8,722, while parts like engines and transmissions raise production costs by $4,239–$4,911 per vehicle for the Detroit Three. Even U.S.-assembled vehicles, like Ford’s F-150, incur costs due to imported components from Canada and Mexico, which supply 40% and 20% of U.S. vehicle parts, respectively. Automakers may absorb some costs initially, but most are passed to consumers, with new vehicle prices potentially rising by $2,000–$10,000.

Shift in Consumer Demand Toward Used Parts: As new vehicle prices climb (averaging $48,641 in January 2025), affordability issues drive consumers toward used and refurbished parts. Cox Automotive notes a tight supply of used cars under $15,000, increasing demand for cost-effective engines and transmissions from platforms like All American Motors Hub. Tariffs on imported parts exacerbate repair costs, pushing buyers to local, refurbished engine and Transmission options to maintain older vehicles.

Supply Chain Disruptions: The tariffs disrupt the highly integrated North American supply chain, causing production pauses and layoffs. Stellantis idled factories in Canada and Mexico, laying off 900 U.S. workers, while Audi and Jaguar Land Rover halted U.S. exports. S&P Global Mobility predicts a four-week disruption, reducing U.S. production by 20,000 vehicles weekly. Smaller suppliers, unable to absorb costs, risk bankruptcy, further straining parts availability.

These effects challenge automakers like General Motors (55% of U.S. sales imported) and Volkswagen (43% from Mexico), while Tesla and Ford, with more domestic production, face less exposure but still incur costs from imported engines. The tariffs reshape consumer behavior and industry operations, with long-term implications for pricing and production.

Stock Markets and Trump Tariffs

Donald Trump’s tariff policies have significantly influenced global stock markets, creating volatility as investors grapple with trade war fears and economic uncertainty. In March 2018, the announcement of steel and aluminum tariffs sparked immediate market reactions, with the Dow Jones Industrial Average plummeting 500 points as industries reliant on these materials faced higher costs. In May 2019, Trump’s threat of tariffs on auto imports led to a 3% drop in General Motors’ stock, reflecting concerns over disrupted supply chains and reduced competitiveness. However, the January 2020 U.S.-China Phase One trade deal brought temporary relief, with auto stocks recovering slightly as trade tensions eased.

In 2025, Trump’s re-escalation of tariffs, including a 10% baseline on most imports and up to 145% on Chinese goods, triggered severe market turbulence. The S&P 500 saw its worst drop since June 2020, falling 4.84% on April 3, 2025, losing $6.6 trillion in value over two days. Companies like Nike and Apple, heavily reliant on global supply chains, dropped 14% and 9%, respectively. A brief market rally followed Trump’s 90-day tariff pause on April 9, 2025, with the S&P 500 surging 9.5%. However, uncertainty persists, with Goldman Sachs estimating a 1-2% S&P 500 earnings decline per 5% tariff increase. Retaliatory tariffs from China and the EU further threaten global growth, with economists warning of inflation and potential recession risks.

Case Study – Nissan Skyline R34 & Other Models

The Nissan Skyline R34, a coveted niche vehicle among enthusiasts, faces significant impacts from Trump’s 25% tariffs, particularly on its imported engines like the RB26DETT. As a Japanese import, the R34, no longer in production, relies on imported used or aftermarket parts, which now incur a 25% duty effective May 3, 2025. 

This increases costs for collectors and modifiers, with RB26DETT engines, previously priced around $10,000–$15,000, potentially rising by $2,500–$3,750. Japan’s tariff reprieve offers no relief for R34 parts, as many are sourced globally, including from Canada and Mexico, both hit by tariffs. This cost hike reduces affordability, limiting imports and pushing enthusiasts toward domestic alternatives or refurbished engines from suppliers like All American Motors Hub.

Other niche models, like Mitsubishi’s Lancer Evolution with its 4G63T engine, face similar challenges. Tariffs on these imported engines and transmissions raise restoration costs, as parts often come from Japan or Mexico. Mitsubishi paused U.S. deliveries, holding vehicles at ports to assess tariff impacts, further tightening supply. 

Enthusiasts are turning to locally refurbished engines, which avoid import duties and offer cost savings, though quality varies. For example, a refurbished RB26DETT from All American Motors Hub could save 20–30% compared to imported units, but supply constraints may limit options.

The tariffs also affect modern Nissan models like the Rogue, with 27% of U.S. sales sourced from Mexico. Production pauses for models like the Infiniti QX50 highlight supply chain vulnerabilities, increasing reliance on domestic or refurbished parts. This shift challenges niche vehicle owners, balancing higher costs against sourcing reliable, locally rebuilt components to maintain their vehicles.
