If your 2022 Hyundai Kona is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The 2022 Kona offers only four-cylinder engines: the 2.0L naturally aspirated and 1.6L turbo (N Line). Neither has a cylinder 5, making P0305 technically anomalous.
2022 Kona Engine Options
The first-generation 2022 Kona offers the 2.0L Nu I-4 (147 hp) on standard models and the 1.6L Gamma Turbo I-4 (195 hp) on N Line trim. Both are four-cylinder engines with cylinders numbered 1-4. The Kona Electric has no internal combustion engine at all.
Why P0305 Cannot Be Valid
All Kona gasoline engines have exactly four cylinders. A P0305 code references a non-existent cylinder 5, indicating a diagnostic error rather than an actual misfire.
Possible Causes
ECM software issues can store invalid codes. Scan tool communication errors may misread data. Low 12-volt battery voltage affects computer reliability. Aftermarket diagnostic tools may have compatibility issues with Hyundai systems.
Diagnostic Recommendations
Use a Hyundai GDS or compatible scan tool to verify codes. Test battery condition. If actual misfire symptoms exist, focus on cylinders 1-4. Clear the erroneous code and monitor.
