The 2024 Hyundai Tucson features 4-cylinder powertrains—the 2.5L MPI or 1.6L turbocharged hybrid options. All configurations contain only cylinders 1 through 4. When P0306: Cylinder 6 Misfire Detected appears, you're encountering an anomalous code.
Fourth-Generation Tucson
The current Tucson (2022+) offers only 4-cylinder engines, including hybrid and plug-in hybrid variants. No V6 option has ever been available in the Tucson. P0306 cannot indicate an actual misfire since cylinder 6 doesn't exist.
Why This Erroneous Code Appears
Generic scanners may misinterpret Hyundai's diagnostic protocols. Hybrid system complexity can confuse some diagnostic tools. Aftermarket OBD devices create potential conflicts. 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. Inspect the OBD-II port for damage. Remove aftermarket devices temporarily. Focus on legitimate misfire codes (P0301-P0304).
Modern Crossover Technology
The Tucson's efficient powertrains and advanced features make it an excellent compact SUV. Use valid codes for actual diagnostic concerns.
