If your 2024 Hyundai Kona is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The completely redesigned 2024 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.
2024 Kona - Complete Redesign
The second-generation 2024 Kona features larger dimensions and updated powertrains. Engine options include the 2.0L Smartstream I-4 (147 hp) and 1.6L Turbo I-4 (190 hp on N Line). All are four-cylinder configurations.
Why P0305 Cannot Be Valid
All 2024 Kona engines have exactly four cylinders numbered 1-4. A P0305 code references a non-existent cylinder 5, indicating a diagnostic error.
Possible Causes
As a first-year redesign, ECM software calibration issues could cause incorrect codes. Scan tool compatibility with the new platform may cause errors. Low 12-volt battery voltage affects computer reliability. Check for TSBs addressing known issues.
Diagnostic Recommendations
Use a Hyundai GDS or compatible scan tool to verify codes. Check for TSBs. Test battery condition. If actual misfire symptoms exist, focus on cylinders 1-4. Clear the erroneous code.
