The P0303 code in your 2022 Hyundai Tucson indicates the engine control module has identified cylinder 3 as experiencing misfires beyond acceptable limits. The redesigned 2022 Tucson offers the 2.5L Smartstream four-cylinder and 1.6L turbocharged hybrid/PHEV variants. Understanding your specific powertrain ensures accurate diagnosis.
Cylinder 3 Position
All Tucson engines are inline four-cylinders with cylinder 3 positioned third from the front of the engine. The transverse mounting places it toward the firewall side of the engine bay.
Generation-Specific Considerations
The 2022 Tucson represents a complete redesign with new powertrains and technology. First-year refinements may be addressed through Technical Service Bulletins. Check for applicable updates.
Common P0303 Causes at Two to Three Years
At this relatively young age, most misfires result from ignition component issues or fuel quality problems. Manufacturing variations can cause early failure. Software calibration updates may improve operation. Turbo systems may develop boost leaks.
Hybrid-Specific Notes
For hybrid and PHEV models, the engine operates intermittently based on driving demands. Misfires may be more noticeable during sustained engine operation. The hybrid system cannot fully compensate for significant misfires.
