The 2024 Cadillac XT6 continues to deliver three-row luxury crossover excellence with refined powertrain options. When a P0304 code appears indicating a cylinder 4 misfire, understanding your configuration helps target effective diagnosis.
Understanding P0304 in Your XT6
The 2024 XT6 offers the 2.0L turbocharged four-cylinder or 3.6L V6. Cylinder 4 location varies by engine—rear of the inline-4 or rear left bank of the V6. Both use individual coil-on-plug ignition.
New Model Considerations
Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The proven XT6 platform has established reliability, and component failures on new vehicles are exceptions.
Diagnostic Steps
Identify your engine configuration. Access the cylinder 4 ignition coil. Inspect spark plug condition. On turbo models, verify boost system integrity. Check for software updates.
Resolution Path
Warranty coverage applies to 2024 models. Have your Cadillac dealer diagnose using factory equipment. Component failures causing P0304 should be covered.
