The 2024 Ram 3500 represents the pinnacle of heavy-duty truck capability with its robust 6.4L HEMI V8 gasoline engine. When a P0304 code appears indicating a cylinder 4 misfire, addressing it promptly ensures this commercial-grade truck maintains the dependable power essential for your work needs.
Understanding P0304 in Your Ram 3500
The 6.4L HEMI in the Ram 3500 is purpose-built for heavy-duty applications without the cylinder deactivation found in lighter trucks. Cylinder 4 is positioned on the right (passenger) bank of the V8. The powertrain control module monitors each cylinder's contribution through crankshaft position analysis to detect misfires accurately.
New Vehicle Considerations
Misfires on new 2024 models are unusual and typically indicate component defects covered under warranty. The heavy-duty HEMI is built for reliability in demanding commercial applications, and factory defects are exceptions. Software updates addressing calibration may also be available for first-year production.
Diagnostic Steps
Access the cylinder 4 ignition coil on the right bank. Inspect for any obvious defects or damage. The individual coil-on-plug design allows targeted testing by swapping between cylinders. Verify spark plug installation and condition. Check for technical service bulletins.
Resolution Path
Warranty coverage applies to component failures on 2024 models. Have your Ram dealer diagnose using factory equipment and current technical information. Component failures causing P0304 are typically covered under powertrain warranty.
