When your 2024 Kia Carnival displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2024 Carnival continues with the 3.5L Lambda III V6 producing 290 horsepower. With six cylinders, P0305 is a legitimate diagnostic code.
2024 Carnival Powertrain
The 2024 Carnival uses Kia's 3.5L Lambda III direct-injection V6 paired with an 8-speed automatic transmission. This is the only engine available across all Carnival trims. No hybrid variant is offered.
Cylinder 5 Location
On the 3.5L V6, cylinder 5 is on the rear bank (toward the firewall) in the center position. Access may require removal of intake components due to the transverse mounting.
Common Causes
On a newer 2024 model, manufacturing defects or loose connections are more likely than wear-related issues. Ignition coil failure can occur. Direct injection carbon buildup is less relevant on newer vehicles. Check for TSBs. Spark plug defects are possible but uncommon.
Diagnostic Process
Read all codes and freeze frame data. Check for Kia TSBs. Verify ignition system connections. Inspect cylinder 5's spark plug and ignition coil. A 2024 model should have full warranty coverage.
