When your 2020 Dodge Charger displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2020 Charger offers V6 and V8 engine options, all with six or more cylinders, making P0306 a valid diagnostic code.
2020 Charger Engine Options
The 2020 Dodge Charger offers the 3.6-liter Pentastar V6 (300 hp), 5.7-liter HEMI V8 (370 hp), 6.4-liter HEMI V8 (485 hp), and supercharged 6.2-liter Hellcat V8 (707+ hp). All engines have six or more cylinders.
MDS Considerations on V8
HEMI V8 engines feature Multi-Displacement System (MDS) that deactivates cylinders including #6. MDS solenoid or lifter issues can cause misfire symptoms during cylinder deactivation.
Common Causes
Ignition coil failure, spark plug wear, MDS lifter problems (V8), and fuel injector issues are typical across Charger engine options.
