What is the GPOP - Issue Review System?
The GPOP - Issue Review System communication, dated September 24, 2025, details a data collection initiative for certain 2021-2026 model year vehicles.

Data Collection Procedure
To assist with monitoring and quality improvement of the 3.6L engine, technicians are required to record specific engine data during the first three oil changes.

- Prior to performing the oil change, connect the wiTECH diagnostic tool to the vehicle.
- Navigate to the topology screen within the action item section of the wiTECH software.
- Once the topology screen successfully loads, disconnect the wiTECH tool and proceed with the standard oil change procedure.
This ensures that vital operational data is captured without significantly altering the oil change process itself. The collection of Jeep Wrangler 3.6L oil change data helps the manufacturer analyze real-world usage patterns.
