What company does Honda use for parts?
Honda doesn't rely on a single company for parts; it sources components from a broad, global network of manufacturers. This diversified approach helps ensure stable supply, competitive pricing, and consistent quality across Honda's lineup.
In practice, Honda works with hundreds of suppliers worldwide, spanning major automotive groups to regional manufacturers. The exact partners vary by vehicle program, region, and production year, and Honda maintains certification and quality controls across its supplier base. For genuine replacement parts, Honda channels parts through authorized dealers and regional distribution networks.
A diversified supplier base
Like most global automakers, Honda maintains a tiered supplier strategy, validating suppliers for specific parts and regions and coordinating integrated supply chains to prevent shortages and delays.
Major supplier partners
Below is a representative, non-exhaustive list of the kinds of suppliers Honda works with for key parts. The exact partner mix varies by model, region, and year.
- Denso Corporation — powertrain components, electronics, and HVAC systems used across many Honda models.
- Aisin Seiki Co., Ltd. — transmissions, drivetrain components, and other drivetrain parts.
- Yazaki Corporation — wiring harnesses and electrical components.
- Hitachi Automotive Systems — propulsion and electrification components for some Honda platforms.
- Bosch, Continental, and other Tier-1 electronics suppliers — sensors, controllers, and electronic modules.
- Sumitomo Electric Industries — electrical parts and other components.
- NSK — bearings for drivetrain and steering components.
- Panasonic Automotive Systems — in-vehicle electronics and infotainment components in some regions.
- Regional and smaller Tier-2/Tier-3 suppliers — cover regional parts and specialized components.
Note: This list is indicative. Honda partners with hundreds of suppliers globally, and the exact companies vary by model year, region, and production program. Honda also maintains its own in-house parts distribution network to supply Honda Genuine Parts to dealers and service centers.
Genuine parts and regional distribution
For aftersales, Honda operates through national affiliates such as American Honda Motor Co., Inc. in North America, and equivalent entities worldwide. Honda Genuine Parts are sourced from its supplier network and distributed through authorized dealers and the Honda Parts network to keep vehicles on the road and in warranty.
In summary, Honda relies on a broad, diversified supplier base rather than a single company. This approach supports production resilience, supply stability, and a robust ecosystem for both original equipment parts and replacement parts.
Summary
Honda's parts come from a wide array of global suppliers, including Denso, Aisin Seiki, Yazaki, Hitachi Automotive Systems, Bosch/Continental, Sumitomo Electric, NSK, Panasonic, and many regional manufacturers. The company also maintains a dedicated parts distribution network through regional subsidiaries to serve dealers and customers with Honda Genuine Parts.
