When your 2024 GMC Yukon displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2024 Yukon uses V8 engines exclusively, making P0306 a valid diagnostic code.

The 2024 GMC Yukon offers the 5.3L V8 and 6.2L V8, both with Dynamic Fuel Management. Cylinder 6 is part of DFM deactivation patterns.
New Vehicle Considerations
For 2024 models, manufacturing defects or premature failures are the primary concerns. Full warranty coverage applies.
Diagnostic Approach
Standard V8 misfire diagnosis applies with attention to DFM-related issues. Warranty service is appropriate for confirmed failures.
