Where are Acura car parts made?
Acura parts come from a global manufacturing network, with most North American assembly performed at Honda plants in the United States and Canada, while engines and key components originate from Honda facilities in Japan and other regions. The exact origin of a part depends on the model and year, but Acura’s supply chain is built on a cross-border, multinational production system managed by Honda and its suppliers.
Global manufacturing footprint
Acura relies on a worldwide network to supply parts and assemble vehicles. In addition to North American production, Honda operates plants in Japan and other regions that produce engines, transmissions, and other components used across Acura models.
- United States – major assembly sites including East Liberty Auto Plant in East Liberty, Ohio, and other Honda-related facilities that build Acura models for the U.S. market.
- Canada – Honda of Canada Manufacturing in Alliston, Ontario, which has produced Acura models for North America.
- Japan and other regions – engines, powertrains, and specialized components are produced at Japanese plants and other Honda facilities for global distribution and export.
These plants work together within Honda’s global supply network, coordinating parts flow to meet production schedules across Acura models sold internationally.
North American production hubs
Specific production sites in North America play central roles in assembling Acura vehicles and supplying components for local and regional markets.
- East Liberty Auto Plant, East Liberty, Ohio – a primary site for assembling Acura models destined for the U.S. market.
- Honda of Canada Manufacturing, Alliston, Ontario – a major site for assembling Acura and Honda vehicles for Canada and the United States.
- Performance Manufacturing Center (Marysville, Ohio) – dedicated facility for the high-performance NSX, incorporating specialized production and advanced components.
Together, these North American facilities form a core part of Acura’s regional production capability, aligning assembly with regional demand and supply.
What parts come from where
Parts for Acura vehicles come from a mix of regional assembly plants and cross-border supply lines. Engines, powertrains, and key components often originate from dedicated engine plants in the United States and from Japanese facilities, then move to assembly sites across North America and beyond. Body, chassis, electronics, and interior components are sourced from a combination of regional plants and global suppliers to support multiple models.
- Engines and major powertrains – produced at Honda engine plants in the United States and at Japanese facilities, then shipped to U.S. and Canadian assembly lines as needed.
- Chassis, bodies, and structural components – assembled or stamped at North American plants that build Acura models for the region, with certain parts sourced from Japan or other facilities.
- Electronics, infotainment, and interior parts – supplied by a mix of Honda/EU suppliers and Japanese facilities, distributed to various assembly lines.
- Specialized components (e.g., NSX powertrain and performance parts) – produced at dedicated facilities such as the Performance Manufacturing Center in Marysville, Ohio, or sourced from Honda’s advanced production network.
The exact origin of individual parts varies by model and model year, reflecting the flexibility of Honda’s global supply chain to balance cost, capacity, and lead times.
Quality and supply chain
Honda and Acura maintain stringent controls to ensure quality and supply continuity across their international network. The framework includes supplier qualification, rigorous testing, and proactive risk management to handle disruptions.
- Extensive supplier audits and certification processes to ensure part quality and reliability.
- Diversified sourcing and regionalization to mitigate supply risks and reduce lead times.
- Just-in-time logistics coordinated across plants to optimize inventory and production flow.
- Robust recall readiness and field-action protocols to address issues quickly if they arise.
These practices help Acura maintain consistent quality while adapting to shifts in demand and global events that affect manufacturing and logistics.
Summary
In short, Acura parts are produced through a global network managed by Honda, with primary North American assembly centered in U.S. and Canadian plants (notably East Liberty and Alliston) and specialized components such as the NSX originating from dedicated facilities in Marysville, Ohio. Engines and other core components come from both U.S. and Japanese facilities, and a broad network of suppliers provides electronics, interiors, and various subsystems. The result is a multinational, highly integrated production system designed to deliver Acura vehicles with consistent quality across markets.
