Toyota Rises to the Top in 2025 Supplier Relations Study, Leaving Competitors Behind
In its 25th annual Working Relations Index® (WRI®) study, Plante Moran has once again provided insights into the dynamics between North American automotive manufacturers and their suppliers. The recent findings indicate a significant shift among the major players, with Toyota, Honda, and General Motors demonstrating notable improvement in their supplier relationships. In contrast, Nissan, Ford, and Stellantis have seen their standings decline amidst challenging market conditions.
This year's report underscores the resilience of the top three OEMs in the face of unprecedented market volatility, which has been marked by changing government policies, cancellations of EV programs, and the looming presence of cost-competitive Chinese automotive entries. The survey, conducted from mid-February to mid-April, involved feedback from 665 executives representing 398 Tier-1 suppliers, providing a comprehensive overview of supplier perceptions across different automakers.
The results reflect that Toyota secured the first position, soaring 18 points to achieve a score of 386. This marks Toyota's highest score in the history of the WRI since reaching 415 in 2007. Honda and General Motors also demonstrated commendable improvement, with Honda climbing 3 points to 347 and GM achieving a significant leap of 11 points, landing at 310, marking a notable comeback for the American automaker that decades ago recorded the lowest score in the study.
Conversely, Nissan saw a decline of 6 points, stabilizing at 249, while Ford remained steady but low at fifth place, also losing 6 points. Stellantis, unfortunately, fell by a staggering 11 points, remaining at the bottom with a score of 141. The data indicates that the gap between Toyota and Stellantis is a striking 245 points, highlighting stark differences in OEM performance.
The survey reveals that suppliers value balanced financial risk and transparency from OEMs regarding future market strategies. Dr. Angela Johnson from Plante Moran noted that suppliers perceive fairness, accountability, and trust as crucial elements shaped by OEM decisions that impact their financial health. The top three companies excel in these areas, offering suppliers better cost management and a supportive environment during uncertain times.
Communication, responsiveness, and consistent engagement are critical factors that set the top-tier OEMs apart from their lower-ranking counterparts. As Dr. Johnson explains, streamlined interactions help suppliers function more effectively and nurture stronger partnerships, enabling both parties to navigate market uncertainties with shared risk and expenses.
Several crucial themes emerged from the 2025 WRI findings:
1. Strengthened Partnerships: The top three OEMs capitalized on their established relationships, significantly enhancing their partnerships with suppliers compared to their bottom-tier competition. This collaborative approach led to improved joint problem-solving amidst economic and industry challenges.
2. Essential Fundamentals: Trust derives from the fundamentals of supplier-OEM interactions. Enhancements in specific behaviors, such as timely payments, accessibility, and ongoing collaborative discussions, have fostered an environment more conducive to productive partnerships.
3. Consistency and Strategic Alignment: Effective alignment of OEM strategic goals contributes to lower perceived risks and reduced service costs. Toyota and Honda have ingrained these principles into their corporate cultures, while GM is making strides to overhaul lingering outdated practices.
The 25th annual WRI study illustrates the ongoing trends in supplier relationships within the competitive automotive landscape. Companies like Toyota, Honda, and GM have exhibited both resilience and forward momentum, while Nissan, Ford, and Stellantis face lingering challenges. As these dynamics continue to evolve, the emphasis on strong, transparent, and cooperative relationships will only become more pivotal for the sustainable success of OEMs and their suppliers alike. With new leadership and ongoing adjustments, these companies must focus on maintaining trust and alignment to thrive in the shifting automotive market.
