A P0303 code in your 2022 Hyundai Kona indicates the engine control module has detected persistent misfires at cylinder 3. This compact SUV offers two gasoline engine options: the 2.0L four-cylinder (147 horsepower) and the 1.6L turbocharged four-cylinder in N Line (195 horsepower). Understanding which powertrain your Kona uses is essential for diagnosis.
Cylinder 3 Location
Both Kona engines are inline four-cylinders with cylinder 3 positioned third from the front of the engine. The transverse mounting places it toward the firewall, standard for Hyundai's compact vehicle platforms.
Engine Options
The base 2.0L Smartstream engine provides efficient, naturally aspirated power for everyday driving. The 1.6L turbo in N Line adds forced induction for sportier performance, operating under higher cylinder pressures that demand more from ignition components.
Common P0303 Causes at Two to Three Years
At this relatively young age, most misfires stem from ignition component issues or fuel quality problems. Manufacturing variations can cause early failure. Contaminated fuel affects combustion. Boost leaks in turbocharged models disrupt air-fuel mixture calculations.
Compact SUV Considerations
The Kona's smaller engine compartment can create different thermal patterns compared to larger vehicles. Heat management around cylinder 3 affects ignition component longevity.
