The 2022 Hyundai Kona features 4-cylinder engines—the 2.0L MPI or 1.6L turbocharged engine depending on trim. Both are inline-4 configurations with only cylinders 1 through 4. When P0306: Cylinder 6 Misfire Detected appears, you're encountering an anomalous code.
Subcompact Crossover Powertrain
The Kona offers efficient 4-cylinder options appropriate for its subcompact size. No V6 has ever been offered. P0306 indicates a cylinder that doesn't exist—it's a diagnostic error, not an engine problem.
Why This Erroneous Code Appears
Generic scanners may misinterpret Hyundai's protocols. Aftermarket OBD devices create conflicts. Scanner databases may produce incorrect cylinder codes. ECU communication errors generate false codes.
Proper Diagnostic Approach
Clear all codes and drive through various conditions. Use Hyundai GDS or professional equipment for accurate readings. Focus on legitimate misfire codes (P0301-P0304).
Efficient Urban Transportation
The Kona's 4-cylinder engines provide efficient city-friendly power. Use valid codes for any actual concerns.
