The 2023 Dodge Charger represents the final production year of the current generation, featuring powerful engine options from the V6 to supercharged HEMI variants. When a P0304 code appears indicating a cylinder 4 misfire, understanding your powertrain helps target accurate diagnosis.
Understanding P0304 in the 2023 Charger
Cylinder 4 location varies by engine. In the 3.6L V6, cylinder 4 is on the rear left bank. In HEMI V8 configurations, cylinder 4 is on the right (passenger) bank. The engine control module monitors combustion quality through crankshaft position analysis.
Final Year Production
As the last year of this Charger generation, the proven powertrains have reached peak refinement. Misfires on newer vehicles typically indicate component issues rather than design problems. If within warranty, component failures should be covered.
Diagnostic Process
Identify your engine and locate cylinder 4. Access the ignition coil and inspect condition. Check spark plug electrode wear. On 5.7L HEMI models with MDS, monitor whether misfires correlate with cylinder deactivation events.
Resolution Strategy
Replace spark plugs with Mopar specifications. Test ignition coil output. If warranty coverage applies, have your dealer diagnose for covered repairs. Address any MDS concerns on applicable HEMI models.
