The 2022 Hyundai Santa Fe offers 4-cylinder powertrains—the 2.5L MPI, 2.5L turbo, or hybrid variants. All are inline-4 configurations with only cylinders 1 through 4. When P0306: Cylinder 6 Misfire Detected displays, you're facing an anomalous code.
Updated Powertrain Lineup
The 2022 Santa Fe updated its engine options with the new 2.5L family. No V6 was offered. P0306 indicates a cylinder that doesn't exist—it's a diagnostic error.
Sources of Erroneous P0306
Scanner confusion with older V6 Santa Fe models. Generic scanners may misinterpret current protocols. Hybrid system complexity can confuse some tools. Aftermarket devices create potential conflicts.
Diagnostic Protocol
Clear all codes and drive through various conditions. Use Hyundai GDS or professional equipment for accurate readings. Focus on valid misfire codes (P0301-P0304).
Modern Efficiency
The Santa Fe's 4-cylinder and hybrid options provide efficiency without sacrificing capability. Use valid codes for concerns.
