The redesigned 2024 Lexus RX features new powertrain options including a 2.4L turbocharged four-cylinder and updated hybrid systems. When a P0304 code appears indicating a cylinder 4 misfire, understanding your specific configuration guides accurate diagnosis.
Understanding P0304 in the 2024 RX
The current RX offers the 2.4L turbo four-cylinder (RX350) and hybrid options. For the turbo model, cylinder 4 is at the rear of the inline-4 engine. The engine control module monitors combustion events through crankshaft position analysis.
New Platform Considerations
The 2024 RX introduced new powertrain options on a redesigned platform. Misfires on new vehicles are uncommon and typically indicate component issues covered under warranty. Software updates may address calibration refinements on first-year production.
Diagnostic Steps
Identify your powertrain configuration. Access the cylinder 4 ignition coil. On turbo models, check for boost leaks. Inspect spark plug condition. Verify all software updates have been applied.
Resolution Path
Warranty coverage applies to 2024 models. Have your Lexus dealer diagnose using factory equipment. Component failures causing P0304 should be covered under warranty.
