If your OBD-II scanner is displaying a P0306 code on your 2024 Lexus RX, this situation requires immediate diagnostic investigation because the code indicates a cylinder that doesn't exist in your vehicle's current engine configuration.
2024 Lexus RX Engine Configuration Change
The 2024 Lexus RX represents a new generation that no longer uses a V6 engine. The RX 350 is now powered by a 2.4L turbocharged 4-cylinder engine producing 275 horsepower. The hybrid RX 350h and RX 450h+ use a 2.5L 4-cylinder hybrid powertrain. None of these engines have a cylinder 6.
This is a significant change from previous RX generations (2016-2022) that used the 3.5L V6 engine. If you're seeing P0306, this indicates a diagnostic anomaly that needs resolution.
Possible Explanations
- Vehicle Year Confusion: You may have a 2022 or earlier RX with the V6 engine, but it's being identified as 2024
- Scanner Vehicle Selection Error: The scanner may be configured for a different vehicle or incorrectly reading the VIN
- ECU/Scanner Communication Issue: Data transmission errors generating false codes
- Aftermarket Modifications: If the vehicle has been modified, incorrect code definitions may exist
What to Do Next
Verify your actual engine by checking under the hood. The 2024's 2.4L turbo-4 looks distinctly different from the 2022's 3.5L V6. If your RX does have a 4-cylinder engine, valid misfire codes would only be P0301-P0304.
