The 2024 Mazda CX-50 continues to deliver rugged crossover capability with refined Skyactiv-G engine technology. When a P0304 code appears indicating a cylinder 4 misfire, prompt attention maintains the responsive performance and fuel efficiency this outdoor-adventure crossover provides.
Understanding P0304 in Your CX-50
The Skyactiv-G engine in your 2024 CX-50 uses a high compression ratio design that maximizes combustion efficiency. Cylinder 4 sits at the rear of the inline-4 engine, nearest the firewall. The engine control module monitors each combustion event through crankshaft position analysis, triggering P0304 when cylinder 4 misfires exceed acceptable thresholds.
New Vehicle Considerations
Misfires on new vehicles are uncommon and typically indicate component defects covered under warranty. The 2024 CX-50's high-compression engine requires ignition components in excellent condition—any manufacturing variance can manifest as misfires during the demanding combustion process.
Diagnostic Steps
Access the cylinder 4 ignition coil at the engine's rear. Inspect for any obvious defects or damage. The coil-on-plug design allows isolation testing by swapping between cylinders. Check spark plug condition even on new vehicles, as occasional manufacturing defects occur.
Resolution Path
If within warranty, have your Mazda dealer diagnose the issue. Component failures on new vehicles are typically covered under powertrain warranty. If diagnosing independently, test ignition coil output and verify spark plug condition. Software updates may address engine calibration concerns.
