The 2022 Hyundai Tucson features 4-cylinder engines—the 2.5L MPI or 1.6L turbocharged hybrid variants. Both are inline-4 configurations with only cylinders 1 through 4. When P0306: Cylinder 6 Misfire Detected displays, you're facing an anomalous code.
Redesigned Tucson
The 2022 Tucson introduced Hyundai's bold new design with efficient 4-cylinder powertrains. No V6 was ever offered. P0306 indicates a cylinder that doesn't exist—it's a diagnostic error, not an engine problem.
Sources of Erroneous P0306
Scanner interpretation issues with Hyundai protocols cause false codes. Hybrid variant complexity may confuse generic scanners. Aftermarket devices can interfere with communication. ECU glitches generate incorrect cylinder codes.
Diagnostic Protocol
Clear all codes and drive through various conditions. Use Hyundai GDS or professional equipment for accurate readings. Inspect the OBD-II port for issues. Remove aftermarket devices temporarily. Check for valid misfire codes (P0301-P0304).
Award-Winning Design
The redesigned Tucson offers striking design with efficient powertrains. Focus on valid diagnostic codes for any actual concerns.
