The 2020 Nissan Murano features the 3.5L VQ35DE V6 producing 260 horsepower for premium midsize crossover performance. When P0306: Cylinder 6 Misfire Detected triggers your check engine light, your Murano has identified combustion problems specifically in cylinder 6.
Murano VQ35 Engine
The Murano uses the naturally aspirated VQ35DE—a proven powerplant across Nissan's lineup. Cylinder 6 occupies a position on one bank of the 60-degree V6. Port fuel injection helps maintain clean intake valves compared to direct injection variants.
Common P0306 Causes
Ignition coil degradation from heat cycling affects cylinder-specific spark delivery. Spark plugs nearing service intervals produce weak ignition. Port fuel injector issues disrupt proper atomization. Vacuum leaks create lean conditions in specific cylinders. The transverse V6 mounting may affect heat distribution.
Diagnostic Procedure
Scan for all diagnostic codes to understand the complete picture. Access cylinder 6 and inspect ignition components. Remove and evaluate spark plug condition against mileage. Test fuel injector operation. Perform compression testing to verify mechanical health.
Premium Crossover Reliability
The Murano's VQ35 engine provides refined performance for its premium positioning. Quality diagnosis and repair maintains the comfortable driving experience.
