The redesigned 2024 Infiniti QX80 delivers flagship luxury full-size SUV excellence with an all-new powertrain. When a P0304 code appears indicating a cylinder 4 misfire, understanding the new platform helps target effective diagnosis.
Understanding P0304 in Your 2024 QX80
The completely redesigned 2024 QX80 features new powertrain technology. Cylinder 4 location depends on the specific engine configuration. The engine control module monitors each combustion event through crankshaft position analysis.
New Platform Considerations
The 2024 QX80 represents a complete redesign. Misfires on new vehicles are uncommon and typically indicate manufacturing defects covered under warranty. First-year production may benefit from technical service bulletins as the platform matures.
Diagnostic Steps
Access the cylinder 4 ignition coil based on engine configuration. Inspect for any obvious defects. Check spark plug condition. Verify all software updates have been applied.
Resolution Path
Warranty coverage applies to 2024 models. Have your Infiniti dealer diagnose using factory equipment designed for the redesigned QX80. Component failures should be covered.
