The 2024 Lexus ES continues to deliver luxury sedan excellence with refined powertrain options. When a P0304 code appears indicating a cylinder 4 misfire, prompt attention maintains the smooth operation this flagship sedan provides.
Understanding P0304 in Your ES
The 2024 ES offers the 2.5L four-cylinder or hybrid powertrain. Cylinder 4 is at the rear of the inline-4 engine in both configurations. The engine control module monitors each combustion event through crankshaft position analysis.
New Model Year Considerations
Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The proven 2.5L engine platform has established reliability, and component failures on new vehicles are exceptions.
Diagnostic Steps
Access the cylinder 4 ignition coil at the engine's rear. Inspect for any obvious defects. Check spark plug condition. Verify all software updates have been applied.
Resolution Path
Warranty coverage applies to component failures on 2024 models. Have your Lexus dealer diagnose using factory equipment. Failures causing P0304 should be covered under the comprehensive warranty.
