THE CHALLENGE
A High-Volume Warranty Line Was Creating an Operational Bottleneck
Kumho Tire's warranty department manages a high volume of inbound calls from consumers, dealers, and service centers. The original project was designed around an average of approximately 2,000 warranty calls per month, creating an opportunity to reduce repetitive manual call handling while improving the customer and dealer experience.
PROGRAM OBJECTIVES
Reduce Human Intervention
The phone rings while an advisor is checking in a vehicle.
24/7 Availability
Ensure no call goes unanswered, including nights, weekends, and holidays.
Data-Driven Insights
Capture real-time analytics on common issues, claim trends, and caller sentiment.
Scalability
Build a foundation for future AI integrations across other Kumho departments.

WHAT THIS MEANS FOR KUMHO
The AI Isn't Just Answering Calls. It's Changing How the Warranty Department Operates.
Always Available
90 calls came in outside normal business hours, and 80 were completely resolved without anyone on duty.
Less Interruption for the Team
Sarah independently handled 565 of 689 calls, allowing the human team to focus on more complex conversations.
Better Human Handoffs
The 124 calls that reached a human representative arrived with the conversation already summarized, reducing the need for callers to repeat information.
Clearer Customer Next Steps
Of 416 consumer calls, 308 ended with a specific next step — either the warranty email or a servicing dealer and phone number to schedule an inspection.
Reliable Warranty Information
Every warranty lookup during September returned terms, helping ensure callers received the information they needed.
THE RESULT
Sarah quickly became part of the warranty operation — not simply another technology implementation.
"Those are fantastic numbers, indeed! I for one could not be more pleased with how well Sarah is doing and how much of a difference she has made already.”
