Warranty Engineering & Field Quality Support

Your Trusted Partner for End-to-End Warranty Resolution and Product Improvement

At JLS Engineering Concepts, we understand that product quality doesn’t end at the manufacturing line—it extends all the way into the hands of the customer. Our Warranty Engineering & Field Quality Support services help OEMs and Tier 1 suppliers respond to real-world failures with speed, accuracy, and engineering rigor. We bridge the gap between field issues and root cause resolution through data-driven analysis, boots-on-the-ground support, and actionable insights.

Backed by 25+ years of experience in manufacturing, industrial engineering, and supplier quality, JLS delivers technical solutions that reduce downtime, drive continuous improvement, and protect your brand in the market.

🧩 What We Do

We offer a comprehensive range of services tailored to help manufacturers reduce warranty costs, resolve customer complaints, and improve field reliability:

1️⃣ Warranty Liaison & Field Issue Support

We act as your technical representative at the OEM or supplier plant, dealership, or service center—investigating customer concerns, tracking complaint data, and coordinating real-time issue resolution.

Services Include:

• Participation in daily/weekly market concern meetings

• Liaison between OEM, supplier, and internal engineering teams

• First-response triage and issue documentation

• Escalation tracking and resolution reports

Use Case:
A global Tier 1 supplier receives a sudden increase in seat motor failures from a U.S. OEM. JLS Engineering is dispatched to the OEM’s plant to represent the supplier, collect field return data, and coordinate corrective actions with the supplier’s quality team.

2️⃣ Returned Parts Teardown & Failure Mode Analysis

Our team performs detailed analysis of customer-returned parts and field-reported failures. We inspect, photograph, and disassemble components, and provide root cause documentation aligned with DFMEA, PFMEA, or APQP formats.

Services Include:

• Returned part cataloging, teardown, and inspection

• Failure mode classification

• Root cause hypothesis and verification testing

• Engineering reports with photos and documented conclusions

Use Case:
After repeated customer complaints about HVAC systems making noise under cold starts, JLS receives and dissects returned blower motors from the dealership network. Root cause: an assembly shift in supplier operations caused impeller-to-shroud contact. Solution: supplier process controls updated.

3️⃣ Warranty Data Analytics & KPI Reporting

We help clients make sense of warranty claim data, warranty chargebacks, and cost recovery trends using Excel dashboards, Power BI, and structured reporting.

Services Include:

• Pareto analysis of warranty failures

• Failure rate tracking over time

• Cost per VIN or part number metrics

• Supplier chargeback validation support

Use Case:
An OEM sees increasing warranty costs tied to powertrain seals. JLS analyzes 18 months of claim data, correlates failure rates to seasonal use patterns, and recommends changes in supplier material validation testing.

4️⃣ Field Campaign & Recall Program Engineering

When a service action, recall, or field fix is needed, JLS provides engineering and logistics support to plan, execute, and track campaign results. We ensure field fix compliance while gathering insights for future prevention.

Services Include:

• Campaign planning and dealer bulletin drafting

• Coordination with service technicians and warranty teams

• Field fix verification and validation

• Post-campaign effectiveness reporting

Use Case:
During a safety recall for door harness corrosion, JLS managed campaign logistics, collected technician feedback from 300+ dealers, and analyzed post-fix complaint rates to validate solution effectiveness.

5️⃣ DFMEA Feedback Loop & Preventive Engineering Support

We support DFMEA and validation teams by feeding real-world warranty data into early design reviews, helping teams proactively engineer out known issues before launch.

Services Include:

• Integration of field failure data into DFMEA risk tables

• Design improvement recommendations based on real-world trends

• Engineering signoff support during gate reviews or PPAP

Use Case:
JLS updates the DFMEA of a rear-liftgate actuator using warranty data from over 1,000 units. Our team works with design engineers to recommend a housing reinforcement that eliminates stress fracture failure over 5-year life cycle testing.
