Memory chip shortage and tight cross-border trucking affect automotive supply chains

Automakers are navigating a convergence of AI-driven component shortages, trade policy uncertainty, cross-border capacity constraints and critical infrastructure dependence. This increases the importance of sourcing flexibility, supply chain visibility and transportation resilience across North America.

Automotive sector competes for essential computer chips

What’s happening

AI demand is creating a memory shortage for automakers. Artificial intelligence is creating an unexpected challenge for vehicle manufacturers worldwide. As technology companies race to expand AI infrastructure, automakers find themselves competing for the memory chips that power everything from infotainment systems to advanced driver-assistance technologies.

What's going on

• Dynamic random-access memory is essential for today's increasingly software-driven vehicles.
• Leading manufacturers, including Samsung and Micron, are directing more production toward higher-margin AI and data centre applications.
• By the end of 2026, data centres are expected to consume roughly 70% of global memory production.
• Of the remaining 30%, the automotive industry accounts for less than 5%, giving vehicle manufacturers little leverage in competing for available supply. Compounding the challenge, the type of memory chip currently used in most vehicles is also being phased out by suppliers.

Why it matters

Unlike previous semiconductor shortages, this challenge is being driven by structural shifts in global demand and economic incentives rather than temporary manufacturing disruptions. Automakers in North America, Europe and Asia are all competing for the same increasingly constrained supply of memory.

Looking ahead

Vehicle manufacturers should evaluate sourcing strategies for memory-intensive components and identify potential exposure to long-term semiconductor supply risks as AI investment continues to accelerate.

USMCA review is under way

The six-year review of the trilateral United States-Mexico-Canada Agreement (USMCA) is under way, putting the future of North America's most important automotive trade agreement in focus.

What's going on

• The USMCA review will determine whether the agreement is extended or moves to annual reviews.
• Canada continues to push for the removal of U.S. auto tariffs, while the United States and Canada maintain reciprocal tariffs on some non-compliant vehicles and parts.
• One year after the United States imposed tariffs on certain Canadian-built vehicles and parts that fail to meet USMCA rules of origin, Canadian vehicle imports into the United States are down more than 21%, while Canadian vehicle production has fallen roughly 15% through the first four months of 2026.

What this means

North American automotive supply chains depend on the seamless movement of vehicles and components across the United States, Canada and Mexico. Continued trade uncertainty could influence future sourcing, production and investment decisions throughout the region.

Looking ahead

Automakers should monitor the review closely and evaluate supply chain exposure to cross-border trade policy changes. Greater sourcing flexibility may become increasingly valuable as negotiations evolve.

Gordie Howe bridge delay extends a key supply chain vulnerability

The opening of the Gordie Howe International Bridge between Detroit, Michigan and Windsor, Ontario, has been delayed with no expected opening date given, extending reliance on one of North America's most important freight crossings.

What's going on

• The bridge was built to ease congestion and provide additional cross-border capacity through a direct, uninterrupted highway connection between I-75 in Michigan and Highway 401 in Ontario.
• The delay is tied to ongoing negotiations between the United States and Canada.
• In the meantime, the Ambassador Bridge continues to handle more than one-quarter of U.S.-Canada merchandise trade by value and remains the most important Michigan/Ontario crossing that can accommodate full-size tractor trailers.
• Nearly two million trucks crossed the bridge in 2025, many carrying automotive parts and finished vehicles.

Why it matters

The delay doesn't create a new disruption, but it extends reliance on a critical transportation corridor that remains a single point of failure for many just-in-time automotive supply chains.

Looking ahead

Until the new crossing opens, manufacturers should continue monitoring border performance and maintain contingency plans for critical freight movements.

Cross-border trucking capacity faces new pressure

North American automotive supply chains depend on the efficient movement of parts and finished vehicles across U.S.-Mexico and U.S.-Canada borders. New enforcement actions and driver compliance requirements are increasing pressure on cross-border transportation networks.

What's going on

• Federal enforcement of cabotage, B-1 visa and English-language requirements is reducing the available pool of cross-border drivers at the same time that automakers are becoming increasingly dependant on nearshoring, Mexico-based production and just-in-time supply chains.
• Since spring, at least 3,200 Mexican drivers are reported to have lost authorisation to operate in cross-border lanes, while Mexico's largest trucking association estimates approximately 20,000 driver visas were revoked between April 2025 and April 2026.
• Because many cross-border drivers hold combined B-1/B-2 visas, a revocation can also eliminate the driver’s personal ability to enter the United States, making even unaffected drivers more cautious about taking cross-border loads.
• Cross-border markets continue to adjust. Heightened enforcement has reduced the available driver pool, contributed to tighter capacity in several U.S.-Mexico corridors and placed upward pressure on freight rates.

The logistics takeaway

As cross-border networks become more complex, efficiency gains matter as much as capacity. Shippers can reduce border friction by consolidating freight, optimising delivery flows and working with providers that offer established transportation networks inside Mexico, at the border and beyond.

Cross-border consolidation in particular can help to improve trailer utilisation, reduce border handoffs, lower transportation costs and create more reliable freight flows when capacity tightens.
