A P0302 code on your 2022 Infiniti Q50 indicates that the engine control module has detected cylinder 2 misfires beyond acceptable parameters. This sport sedan features a twin-turbocharged V6 requiring specific diagnostic attention.
2022 Q50 Powertrain
The 2022 Infiniti Q50 is powered by a 3.0L twin-turbocharged V6 available in two output levels: 300 horsepower (LUXE) or 400 horsepower (RED SPORT 400). Both versions use the VR-series twin-turbo engine.
VR30DDTT Twin-Turbo V6
The VR30 engine features twin turbochargers, direct injection, and sophisticated engine management. High power output demands robust ignition and fuel delivery. Cylinder 2 is located on one bank of the V6.
High-Performance Demands
The Q50, especially in RED SPORT trim, is designed for spirited driving. High-boost operation stresses ignition components. Ensure spark plugs and coils meet specifications for the application.
Sport Sedan Refinement
Despite its performance orientation, the Q50 is expected to deliver smooth operation. Misfires create rough running that affects the luxury sport sedan experience.
Twin-Turbo Diagnostic Focus
Both turbochargers must provide balanced boost for proper combustion. Bank-specific boost issues can affect individual cylinders. Monitor both turbo systems during diagnosis.
