A P0302 code on your 2022 Dodge Hornet indicates that cylinder 2 is experiencing misfires detected by the engine control module. This new compact SUV features a turbocharged four-cylinder engine requiring specific diagnostic approaches.
2022 Hornet Powertrain Introduction
The Dodge Hornet debuted in 2022 with a 2.0L turbocharged four-cylinder engine producing 268 horsepower. A plug-in hybrid R/T version offers additional electric power. The four-cylinder design makes each cylinder critical to smooth operation.
Turbocharged Engine Analysis
The 2.0L turbo operates under boost pressure during acceleration, increasing combustion chamber stress. Cylinder 2 misfires may relate to boost leaks, wastegate issues, or ignition components struggling under boost conditions.
Four-Cylinder Sensitivity
With only four cylinders, each contributes 25% of engine power. A single misfiring cylinder creates significant rough running, reduced power, and noticeable vibration. The problem is immediately apparent to the driver.
Direct Injection Considerations
The 2.0L engine uses direct fuel injection, delivering fuel at high pressure into the combustion chamber. This design can contribute to intake valve carbon buildup over time, though it's typically more of a concern on higher-mileage vehicles.
New Model Considerations
As a new vehicle, your 2022 Hornet should be under comprehensive warranty coverage. Misfire-related repairs would typically be covered. Document symptoms and schedule a dealer appointment for proper diagnosis.
