A P0302 code on your 2024 Jeep Grand Wagoneer indicates the engine control module has detected misfires in cylinder 2. The 2024 Grand Wagoneer offers the 6.4L Hemi V8 or the twin-turbo 3.0L Hurricane inline-6 engine options. Each powertrain has specific diagnostic considerations for misfire resolution.
2024 Engine Options
The 6.4L Hemi produces 471 horsepower with MDS cylinder deactivation. The 3.0L Hurricane twin-turbo inline-6 produces up to 510 horsepower. Cylinder 2 location differs: driver's side bank on the V8, second from front on the inline-6. Each engine has different potential misfire causes.
6.4L Hemi Considerations
The V8's port injection avoids carbon buildup concerns. MDS system can cause cylinder-specific issues if lifters or solenoids malfunction. Standard ignition and fuel system problems also apply. The proven Hemi platform has well-documented diagnostics.
Hurricane I-6 Specifics
The twin-turbo inline-6 adds boost system variables. Direct injection can lead to carbon buildup over time. Boost pressure irregularities from wastegate or turbo issues can cause misfires. The newer engine design may have first-year refinements.
Symptom Recognition
Both engine types display rough idle, vibration, and hesitation with misfires. The luxury SUV's refined character suffers when cylinder 2 misfires. Check engine light accompanies the condition.
