The 2024 GMC Yukon continues as the benchmark for full-size SUV capability, powered by proven V8 engines with Dynamic Fuel Management. When a P0304 code appears indicating a cylinder 4 misfire, addressing it promptly maintains the refined performance this premium SUV delivers.
Understanding P0304 in the 2024 Yukon
The Yukon's 5.3L and 6.2L V8 engines feature Dynamic Fuel Management for optimal efficiency. Cylinder 4 is positioned on the right (passenger) bank of the V8. The powertrain control module monitors each cylinder's contribution through sophisticated crankshaft position analysis.
New Vehicle Considerations
Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The proven V8 architecture is reliable, and component failures are exceptions. Software updates addressing calibration refinements may be available.
Diagnostic Steps
Access the cylinder 4 ignition coil on the right bank. Inspect for any obvious defects. Check spark plug condition. On new vehicles, manufacturing variances occasionally cause issues. Verify all software updates have been applied.
Resolution Path
Warranty coverage applies to component failures on 2024 models. Have your GMC dealer diagnose using factory equipment and current technical information. Component failures causing P0304 should be covered under powertrain warranty.
