Toyota’s recent achievement in the 2026 Plante Moran Working Relations Index (WRI) matters to everyday people because it directly affects the reliability and affordability of the vehicles they drive. As automakers enhance their relationships with suppliers, consumers can expect improved products and services in the automotive market.

Auto Industry Relationships Take a Positive Turn

In an impressive first for the automotive industry, major North American automakers, including Toyota, Honda, and General Motors, have all improved their supplier relationship scores in the latest WRI. This marks the first time in the study’s 26-year history that every major player advanced at the same time. Given the backdrop of challenges like tariffs and the rise of electric vehicles, these results show a significant shift in how automakers and suppliers are working together.

The WRI results highlight how pivotal communication and collaboration have become in evaluating automakers. In times marked by supply chain disruptions and geopolitical uncertainty, suppliers are rewarding companies that actively engage with them. Even when pricing disputes are unresolved, factors like accessibility and willingness to listen have become crucial for positive evaluations.

Key Players in the Rankings

Toyota emerged as the clear leader, scoring 409 points, making it the first automaker to exceed 400 points since 2007. Honda followed closely with 360 points, showing notable improvement in its standings. General Motors also experienced a positive shift, reaching a record score of 318, while Nissan and Ford improved to 255 and 223, respectively. Although Stellantis remains at the bottom with a score of 163, it too made progress by gaining 22 points.

Dr. Angela Johnson, a principal at Plante Moran, expressed surprise at the results, suggesting that, given the industry’s current climate, the positive developments in supplier relationships were unexpected. The study collected over 10,000 comments from suppliers, which is a significant increase from earlier editions. This feedback indicated that actions such as holding meetings, responding promptly, and being transparent were key factors that contributed to improved relationships.

Communication is Key

One major takeaway from the study is that suppliers now prioritize communication and transparency more than ever. This shift is essential given the ongoing negotiations over tariffs and the costs associated with electric vehicle production. Automakers who provide clear and honest communication tend to fare better in supplier evaluations.

Toyota and Honda excelled in their dealings regarding tariff negotiations, demonstrating strong support for their suppliers. General Motors received positive remarks for its responsiveness, although some suppliers have raised concerns about the operational demands from the company’s resilience initiatives. Ford also gained recognition for enhancing accessibility, partly due to initiatives led by Liz Door, Ford’s chief supply chain officer. They implemented a two-way supplier scorecard for better clarity in evaluations.

The Road Ahead for Automotive Suppliers

The 2026 study indicated that Japanese automakers, including Toyota and Honda, continue to outperform their U.S. competitors in areas like trust and communication. The historical dynamics of the relationships between automakers and suppliers reveal a deeper issue. Traditionally, Detroit automakers have had more adversarial relationships with suppliers, while Japanese companies have built collaborative models based on mutual respect.

Plante Moran identified six behaviors that foster stronger supplier relationships: commercial fairness, consistency, clear expectations, communication, continuity, and collaboration. The current “permacrisis” environment necessitates a shift toward cooperative relationships rather than purely transactional ones. Dr. Johnson summed up the challenge facing the industry: “Working together is the best way to confront the challenges of the permacrisis, innovate, and grow.”
