When your 2024 Hyundai Kona displays the P0304 code, the engine control module has detected recurring misfires in cylinder 4. The completely redesigned 2024 Kona introduces new powertrain options and platform changes requiring updated diagnostic understanding.
Understanding P0304 in the 2024 Kona
The redesigned 2024 Kona features the 2.0L Smartstream four-cylinder as standard with a 1.6L turbocharged option. The platform redesign includes an updated engine bay layout affecting component access. All four-cylinder configurations position cylinder 4 at the rear of the inline arrangement.
New Platform Considerations
First-year redesigned vehicles may reveal unexpected issues as miles accumulate. The Smartstream engines incorporate advanced efficiency technology. Standard ignition and fuel causes remain the most common P0304 sources regardless of platform changes. Monitor for technical service bulletins addressing new model concerns.
Diagnostic Methodology
Identify your engine configuration. Use a scanner current with 2024 Kona calibrations. Familiarize yourself with the redesigned engine bay layout. Access cylinder 4 and test ignition coil output and spark plug condition. Verify fuel injector operation. Check for manufacturer bulletins.
Repair Implementation
Install Hyundai-approved spark plugs for your specific engine. Replace ignition coils testing outside specifications. Address fuel system concerns. New vehicle warranty may cover manufacturing defects.
