2024 Buick Enclave P0304: Cylinder 4 Misfire Guide

The 2024 Buick Enclave continues to deliver premium three-row SUV excellence with its refined 3.6L V6 engine. When a P0304 code appears indicating a cylinder 4 misfire, prompt attention maintains the smooth ride this luxury crossover provides.

Understanding P0304 in Your Enclave

The Enclave's 3.6L V6 provides refined power for family duties. Cylinder 4 is on the rear of the left bank of the V6. The engine control module monitors each combustion event through crankshaft position analysis.

New Model Considerations

Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The proven 3.6L V6 platform has established reliability, and component failures on new vehicles are exceptions.

Diagnostic Steps

Access the cylinder 4 ignition coil on the left bank. 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 Buick dealer diagnose using factory equipment. Component failures causing P0304 should be covered.
