The 2022 Infiniti QX60 third generation features the 3.5-liter V6 engine (VQ35DD) producing 295 horsepower as its sole powertrain option. This naturally aspirated V6 includes cylinder 5 as a legitimate position. A P0305 diagnostic trouble code indicates the engine management system has detected a misfire at this cylinder.
Understanding P0305 on QX60
The P0305 code signifies "Cylinder 5 Misfire Detected." On Nissan/Infiniti VQ-series V6 engines, cylinder 5 is positioned on the driver's side (left bank). This cylinder contributes to the smooth power delivery expected from Infiniti's three-row luxury SUV.
VQ35DD Engine Features
The VQ35DD uses direct injection technology which can lead to carbon buildup on intake valves over time. This award-winning engine family is known for reliability but requires proper maintenance.
Common Misfire Causes
Cylinder 5 misfires on the QX60 typically result from ignition coil degradation, spark plug wear, fuel injector issues, or carbon deposits on intake valves restricting airflow.
Infiniti Standards
The QX60 should deliver refined, comfortable driving. Any misfire disrupts the premium experience and warrants prompt diagnosis.
