The P0306 diagnostic code on your 2024 Infiniti Q50 indicates a cylinder 6 misfire condition. The Q50's 3.0L twin-turbocharged V6 engine (VR30DDTT) has six cylinders, making this a valid diagnostic code requiring attention.
2024 Q50 Powertrain
The 2024 Infiniti Q50 continues with the proven 3.0L twin-turbo V6, available in 300 hp (Pure/Luxe/Sensory) and 400 hp (Red Sport 400) configurations. Both use the same VR30DDTT engine platform, so diagnostic procedures apply to all variants.
Common Causes of Cylinder 6 Misfire
- Ignition Coil Degradation: Turbo heat stresses ignition components
- Spark Plug Wear: High-pressure combustion accelerates wear
- Direct Injector Issues: Clogging or mechanical failure
- Boost System Leaks: Air leaks affecting cylinder 6
- Carbon Buildup: Intake valve deposits from direct injection
- Mechanical Problems: Low compression from internal wear
