The completely redesigned 2024 Chevrolet Traverse introduces a new 2.5L turbocharged 4-cylinder engine producing 315 horsepower—replacing the previous V6. However, GM also offers an available 3.6L V6 option. When P0306: Cylinder 6 Misfire Detected appears on V6-equipped models, your Traverse has identified combustion problems in cylinder 6.
New Generation Traverse Engines
The 2024 Traverse introduces a major powertrain change with a turbocharged 4-cylinder as standard. However, the 3.6L V6 remains available. If your Traverse has the V6, P0306 is a valid code. If you have the 2.5L turbo-4, P0306 would be anomalous since it has only 4 cylinders.
V6 P0306 Causes
On V6 models, ignition coil degradation affects cylinder-specific spark delivery. Spark plug wear reduces combustion efficiency. Direct injection allows carbon buildup potential. Fuel injector issues disrupt proper atomization. Vacuum leaks create lean conditions affecting specific cylinders.
Diagnostic Approach
First, confirm your Traverse has the V6—the 2.5L turbo-4 showing P0306 is anomalous. For V6 models, scan for all codes. Inspect cylinder 6 ignition components. Remove and evaluate spark plug condition. Test fuel injector operation. Perform compression testing to assess mechanical health.
New Platform Considerations
As a redesigned vehicle, ensure your technician is familiar with the new Traverse platform. Factory diagnostic equipment provides the most accurate readings for this new generation.
