OEM leaders found that warranty recovery challenges aren’t driven by formulas—they’re driven by how responsibility is defined and enforced. The Purchasing & Supplier Cost Sharing Xchange Group benchmarked share rate models, NTF, parts analysis pipelines, transparency, and supplier accountability to uncover where execution breaks down.
The first Purchasing & Supplier Cost Sharing Xchange Group session on March 24 brought together leaders from Bridgestone, Cummins, GM, Mitsubishi Logisnext, Stellantis, Toyota, and VW—and it didn’t take long for a clear theme to emerge:
Most warranty recovery challenges aren’t caused by formulas or systems. The real issues are how responsibility is defined, measured, and enforced across OEMs, suppliers, and dealers.
This inaugural discussion set the tone for what these Xchange Groups are designed to do: move past surface-level benchmarking and into the operational friction that actually slows teams down.
Start With Scope: Ordinary Warranty vs. Recall
One of the first points of alignment was deceptively simple—focus on ordinary warranty recovery, not recalls or field actions.
Why? Because recall recovery is typically more structured: defined populations, clear failure modes, and often governed by indemnification or upfront agreements.
Ordinary warranty, on the other hand, is where things get messy.
- Claims are handled individually unless a formal recovery process exists
- Responsibility is often inferred, not explicitly defined
- Share rates and technical factors become the mechanism for scaling decisions
That’s where most organizations are still struggling—and where this group will continue to focus.
Share Rates Sound Simple—Until You Try to Operationalize Them
Across OEMs, the concept of assigning a supplier “share” of warranty cost is well understood. The execution is where many OEMs struggle.
Some key approaches surfaced:
- Sampling-driven models to establish technical factors
- Default share rates based on design ownership, adjusted over time
- Multi-year agreements that lock in rates with opportunities for supplier challenge
But even with different models, the same friction points showed up repeatedly:
- Lack of clean supplier attribution in raw warranty data
- Complexity from part supersessions, kits, and dual sourcing
- Disagreements over what should (and shouldn’t) count toward the calculation
As one participant put it:
“You want to be proactive with a technical factor, but you need enough data to stand it up—otherwise you’re already behind the eight ball.”
NTF Isn’t a Data Problem—It’s a Philosophy Problem
No topic generated more debate than No Trouble Found (NTF).
At face value, it’s a classification issue. In practice, it’s a battleground over accountability.
Some OEM perspectives were clear:
- If a part is replaced and the issue is resolved, something was wrong
- Excluding NTF entirely can artificially reduce supplier responsibility
- Treating NTF as zero liability may incentivize not finding root cause
One leader put it bluntly:
“If you set NTF to zero, you’re rewarding not finding the problem.”
But the supplier perspective added important nuance:
- Modern service environments rely on module replacement, not deep diagnostics
- Technician variability and dealer behavior can drive “false” replacements
- Suppliers risk being held accountable for issues outside their control
The takeaway? NTF isn’t just a classification—it’s a reflection of how risk is shared (or shifted) across the ecosystem.
Parts Return and Transparency: Where Process Meets Trust
Another area of strong interest was how organizations manage parts return, analysis, and visibility.
More mature models are moving toward:
- A single, integrated pipeline for root cause and recovery (not separate processes)
- Automated technical factor calculations based on categorized outcomes
- Real-time visibility into claims, part status, and financial impact
- Role-based access for engineering, quality, and recovery teams
In these environments, transparency isn’t optional, it’s foundational.
Suppliers see the same data. Disputes are tied to specific categorizations. And decisions move faster because the system, not just the relationship, supports them.
The Real Bottleneck: Financial Execution
Even when responsibility is agreed upon, actually collecting recovery dollars remains inconsistent.
Most participants rely on debit set-off against supplier payables, but:
- Processes break down as organizations scale or evolve
- Accounting ownership is often unclear or deprioritized
- Regional regulations (e.g., Mexico, parts of Europe) complicate execution
It’s a reminder that recovery isn’t complete when the percentage is agreed—it’s complete when the cash moves.
Disputes Aren’t Just Disputes—They’re Different Problems
One of the more practical takeaways was the need to separate types of supplier disputes:
- Technical disputes
- Root cause, part classification, NTF inclusion
- Should be resolved by engineering/quality
- Commercial disputes
- Cost magnitude, perceived fairness, affordability
- Should be handled by purchasing/finance
Blurring these lines slows resolution and frustrates both sides. Structuring them correctly can dramatically improve cycle times.
What’s Next: May 20 Xchange Group Session
The group aligned on continuing the momentum with focused sessions on ordinary warranty recovery best practices. MAPconnected will circulate a list of priority topics for members to rank, ensuring future sessions stay fully aligned to what operators need most.
Next Meetup:
📅 May 20
⏰ 3-4:15 pm ET

Why MAPconnected Xchange Groups Matter
This session is exactly why Xchange Groups exist.
Not for surface-level insights, but for real, operator-to-operator conversations on what’s actually working (and what’s not).
Members gain:
- Peer benchmarking that goes beyond metrics into process and decision-making
- Unfiltered insight from organizations facing the same challenges
- Practical frameworks that can be applied immediately
- Cross-functional perspective spanning purchasing, quality, warranty, and finance
Most importantly, these groups create space to challenge assumptions—whether it’s how NTF is handled, how analysis pipelines are managed, or how responsibility is defined in the first place.
Because in warranty recovery, alignment isn’t just helpful—it’s the difference between a process that works on paper and one that works in reality.
If you’re working through some of these same challenges and want to be part of these conversations, MAPconnected Xchange Groups are now active across six focus areas with more insights like this coming out of every session.
Leadership Xchange Groups Six focus areas:
- Parts Return & Quality Analysis
- Warranty Administration
- Recall, Customer Campaigns & Legal
- TAC – Technical Assistance Centers
- Financial Products & Insurance,
- Purchasing & Supplier Cost Sharing
