The automotive sector is characterized by its finished products: electric cars, trucks, and SUVs that are technologically advanced and powerful.The automotive industry is often seen in terms of its products: electric vehicles, powerful trucks, and technologically advanced SUVs engineered and developed over the years. However, for each vehicle assembled, there is a massive chain of supplier companies providing thousands of parts and components. The cooperation between automakers and such suppliers has always been one of the most crucial and challenging dynamics in the car industry, and it has been marred by difficult negotiations, cost pressures, and conflicting business priorities.

A fascinating change has begun to happen throughout the industry. A new, annual study of the six key North American automakers has found for the first time that they are doing better with their suppliers than at the same time. This accomplishment is much more than just a minor step forward in the business world. It represents a meaningful step towards enhanced communication, more collaboration, and a common purpose to address the many challenges of today’s automobile industry.

Results are from the latest in a series of studies performed by Plante Moran called the 2026 North American Automotive OEM-Supplier Working Relations Index® (WRI®). The findings were so strange that the researchers checked the data several times to ensure that it did not contain any mistakes. Derived from 750 responses from some of the industry’s biggest suppliers, the study provides compelling evidence that the automotive industry is transitioning from transactional to collaborative relationships and partnerships, and that they are seeing these change in the areas of trust, transparency, and long-term collaboration.

1. An Industry-Wide Improvement Never Seen Before

The newest WRI® study found a historic turnaround in the automotive industry, with all the top automakers taking a positive approach to the supplier relationship. This is the first time in the history of the industry that such significant progress has been achieved, reflecting a new attitude towards working together, trusting each other and improving supply chain relationships to ensure vehicles are produced successfully.

Key factors that drive the industry improvement:

• Improved communication with suppliers.
• Increased partnership and collaboration.
• Increased attention paid to fairness.
• Joint solutions to problems.
• Long-term relationship development.

Current challenges for automakers and suppliers include new technologies, economic uncertainty, rising costs and shifting consumer demand. Greater collaboration will enable both parties to better meet the demands of the industry in the face of such challenges. This is an improvement for all manufacturers, indicating that supplier management is no longer just about the negotiation. These traits, including transparency, respect and problem solving, are now regarded as essential to future success by companies.

2. The Toyota Motor Corp. and Honda Motor Co. kept the standard

Toyota’s supplier relationship score was the highest, up 23 points to 409 and its best since 2007. Honda also performed very well, rising by 13 points to score 360, making it one of the best performers in the study. These results highlight the effectiveness of their long-standing commitment to supplier respect, consistency, and open communication. Both automakers have built strong partnerships over many years by focusing on mutual trust and shared success.

Table Tennis and Communication Skills:

• Clear and consistent communication and trust.
• Long-term partnership approach.
• Establish clear expectations with the parties.

Both companies have enjoyed years of successful relationships and that is why they are successful. Their way of working shows that it takes ongoing efforts and objectives to maintain a strong supplier relationship. Cooperation can continue to produce results at every step of the supply chain as Toyota and Honda have proven. Their successes demonstrate how much important a role mutual trust and stability play in the longer-term success of business.

3. General Motors’ long walk towards collaboration

General Motors marked a big improvement with its highest WRI® score ever, rising eight points to 318. This improvement comes after being one of the tougher companies for suppliers to deal with. The progress highlights GM’s ongoing efforts to build stronger communication, improve supplier relationships, and create a more collaborative working environment. Although the journey has taken years, the company’s steady improvements demonstrate its commitment to developing trust and long-term partnerships within its supply network.

A two-way street for GM’s Transformation and Progress:

This turnaround is a testament to how businesses with a troubled past can regain consumers’ confidence with proactive measures. GM’s advances move the company closer to the industry’s top manufacturers’ collaborative standards.

4. Ford’s major turn-around effort

Ford has made the biggest improvement in the latest WRI® study, which scored a 32-point rise to 223. The company has still not reached the levels of some competitors, but this change is significant enough to put them on a much better footing to regaining supplier confidence.

Ford’s Supplier Relationship Improvements:

• Raised supplier listening activities.
• Increased predictability of business interactions.
• Improved lines of communication were created.
• Greater supplier involvement.
• Committed to cultural transformation.

There were many small issues that caused Ford and its suppliers not to trust each other in the past. Recent work has been directed towards tackling these concerns by enhancing engagement and responsiveness. Overall, the company has made strides towards rebuilding the relationship, and it is clear that it will take time, effort, and some changes to their day-to-day business practices to achieve this. Suppliers are starting to take Ford’s commitment to being a more reliable partner into account.

5. Stellantis and Nissan Progress in a Positive Direction

Stellantis and Nissan showed positive results in the latest supplier relationship study. Stellantis rose 22 points to a score of 163 and Nissan went up six points to the highest since 2014. These improvements reflect both companies’ efforts to strengthen communication, improve supplier engagement, and create more balanced business relationships. Although their scores remain behind some industry leaders, the positive momentum shows a clear commitment to rebuilding trust. Continued focus on fairness, transparency, and collaboration will be essential for maintaining long-term progress with their supplier networks.

Positive Changes at Both Companies:

Stellantis experienced a renewed focus on fairness and supplier growth, while Nissan maintained its communication and working relationships. Both companies were improving in the right direction, but with different magnitude of improvements. They’re part of a broader industry change as manufacturers come to understand that better supplier relationships make a healthier automotive ecosystem.

6. Return to in-person collaboration

The unexpected element of better supplier relationships has been the return of face-to-face in the workplace. Buyers and supply chain components rejoined the office and suppliers were reporting increases in access, communication, and response time to challenges.

The advantages of direct collaboration are obvious:

• Faster problem-solving discussions.
• Improved contacts at the personal level.
• Improved communication effectiveness.
• Better decision-making processes.
• Increased team accessibility.

When people meet in person, it’s easier to avoid misunderstandings and they can discuss issues more effectively than if they were speaking over the phone. Personal contact builds better working relationships and promotes effective team working. Stellantis, Ford, and General Motors among other automotive companies have seen the benefits of greater face-to-face interaction. Through their experiences, they have learned that human interaction is still a key element in the sustainability of successful supplier relationships.

7. More Unity Has Resulted From Shared Challenges

Automakers and suppliers now have a new relationship, as recent events such as the impacts of the pandemic, semiconductor shortages, geopolitical tensions, and the high costs of transitioning to EVs have all changed the landscape. These obstacles have spurred both parties to cooperate instead of competing as individual interests.

What are the industry challenges that are generating cooperation:

• The impact on the global supply chain.
• Semiconductor shortage challenges.
• The transition costs of EVs.
• The economy and geopolitics.
• Increased partnership requirements.

Manufacturers and suppliers have come to know how crucial they are to each other to be successful in the long run through the experience of multiple crises. When tackling complex industry issues, the value of collaboration has grown to outweigh confrontation. This change of attitude has improved the interactions of the companies day by day. Many of the frustrations that had impacted business relationships have now been replaced by positive responses and solutions from suppliers.

8. Concentrating on what Companies can control

Many of the big challenges threatening the automotive industry from tariffs to the financial needs of EV development, for instance are not within the scope of the purchasing department’s direct control. Rather than just worrying about these hindrances, businesses have worked to enhance those aspects where real change can occur.

Action Steps for Improvement:

• Appreciating supplier concerns.
• Maintaining transparent communication.
• Helping in times of doubt.
• Improving business responsiveness.
• Improving working relationships.

Suppliers have been aware of manufacturers’ work to keep dialogue open and to be consistently supportive, even as businesses continue to struggle through difficult times. These activities have contributed to building trust in the supply chain. It’s a real-world approach that demonstrates that positive relationships can be cultivated with consistent effort, honesty, and collaboration. There are lots of things that can be done to make a big difference in the long run in our daily life interactions.

9. The 6 Core Principles of Rebuilding Trust

A higher level of trust is one of the key pillars of good supplier relationships, and this latest study revealed that there was a rise in trust in all of the automakers that were assessed. It was one of the most significant increases, as buyer trust in Ford’s purchasing leadership also increased the most.

Strong partnerships are built on six principles:

• Commercial honesty and treatment of others.
• Consistent business practices.
• Establish goals and expectations.
• Open communication channels.
• Long-term collaborative commitment.

These principles offer a clear guideline to manufacturers to enhance their supply chain relationships. Trust is built when you act repeatedly, behave reliably and work constantly to achieve shared success. A company that embraces these values on a regular basis is likely to foster innovation, enhance productivity, and establish enduring business relationships that can meet future demands.

10. The Next Generation of Auto Supplier Relationships

Yes progress has been made; however, some hurdles still exist, particularly for those manufacturers who have long and arduous supplier relationships. It takes time to restore confidence, as it did for suppliers to assess its relationship with the automakers based on past experience.

The future Partnership Success Factors:

• Continued trust-building efforts.
• Long-term cultural transformation.
• Stronger supplier cooperation.
• Better supply chain resiliency.
• Increased innovation opportunities.

Even large suppliers are hesitant to embrace companies that have a complicated history, and the continued improvement will be needed to validate that recent changes are a cultural shift, not just a temporary solution to meet market demands. The recent progress in an improved relationship between car makers and suppliers is a significant milestone for the car manufacturing future. As the automotive industry evolves, stronger partnerships can result in improved products, improved production process, more innovation, and more stable global supply chains.
