P0306 Code: 2022 Genesis G70 – What It Means & Cost to Fix

P0306 Code on 2022 Genesis G70: Cylinder 6 Misfire Diagnosis by Engine Type

A P0306 diagnostic code on a 2022 Genesis G70 indicates a cylinder 6 misfire, but the validity of this code depends on which engine your G70 has.

2022 Genesis G70 Engine Options

  • 2.0T: 2.0L turbocharged 4-cylinder (252 hp) - P0306 is invalid
  • 3.3T: 3.3L twin-turbo V6 (365 hp) - P0306 is valid

If you have the 3.3T V6, this code indicates a genuine cylinder 6 misfire requiring diagnosis. If you have the 2.0T 4-cylinder, P0306 is impossible since that engine only has cylinders 1-4.

V6 Misfire Causes

  • Ignition Coil Failure: Turbo heat accelerates coil wear
  • Spark Plug Issues: Worn electrodes or contamination
  • Fuel Injector Problems: Direct injection issues
  • Boost Leaks: Twin-turbo system air leaks
  • Carbon Buildup: Intake valve deposits
  • Mechanical Issues: Low compression
