P0304 Code: 2024 Lexus NX – What It Means & Cost to Fix

2024 Lexus NX P0304: Cylinder 4 Misfire Guide

The 2024 Lexus NX delivers luxury compact crossover excellence with advanced powertrain options. When a P0304 code appears indicating a cylinder 4 misfire, understanding your specific configuration helps target effective diagnosis.

Understanding P0304 in Your NX

The 2024 NX offers multiple powertrain configurations including the 2.4L turbocharged four-cylinder and hybrid options. Cylinder 4 is at the rear of the inline-4 engine in all configurations. 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 NX platform has established itself since the 2022 redesign, but component failures occasionally occur on any vehicle.

Diagnostic Steps

Identify your powertrain configuration. Access the cylinder 4 ignition coil at the engine's rear. 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 and current technical information. Component failures causing P0304 should be covered under warranty.
