If your 2024 Kia Sportage is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The 2024 Sportage offers only four-cylinder powertrains: the 2.5L naturally aspirated, 1.6L turbo hybrid, and 1.6L turbo plug-in hybrid. None have a cylinder 5, making P0305 technically anomalous.
2024 Sportage Powertrain Options
The fifth-generation 2024 Sportage offers the 2.5L Smartstream I-4 (187 hp), 1.6L Turbo Hybrid (227 hp combined), and 1.6L Turbo PHEV (261 hp combined). All use four-cylinder engines with cylinders numbered 1-4. No V6 is available on the current Sportage.
Why P0305 Cannot Be Valid
All 2024 Sportage powertrains use four-cylinder engines. 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—especially important in hybrid models. Aftermarket tools may have compatibility issues.
Diagnostic Recommendations
Use a Kia-compatible scan tool to verify codes. Test 12-volt battery condition. If actual misfire symptoms exist, focus on cylinders 1-4. Clear the erroneous code and monitor.
