If your OBD-II scanner displays a P0306 code on your 2022 Lexus NX, this situation requires immediate diagnostic investigation because the code references a cylinder that doesn't exist in your vehicle.
2022 Lexus NX Engine Options
The 2022 Lexus NX is the first model year of the second-generation NX, offering the following powertrains:
- NX 250: 2.5L 4-cylinder engine (203 hp)
- NX 350: 2.4L turbocharged 4-cylinder engine (275 hp)
- NX 350h: 2.5L 4-cylinder hybrid (240 hp combined)
- NX 450h+: 2.5L 4-cylinder plug-in hybrid (304 hp combined)
All 2022 NX variants use 4-cylinder engines. There is no V6 option available. A 4-cylinder engine only has cylinders 1 through 4, making a P0306 (cylinder 6 misfire) code physically impossible.
Why You're Seeing This Code
- Scanner Error: The diagnostic tool may be misconfigured or experiencing communication issues
- Vehicle Misidentification: The scanner may be reading incorrect vehicle parameters
- ECU Glitch: Rare software corruption generating impossible codes
- Confusion with Lexus RX: The similarly-sized RX350 (V6) may have been selected instead of NX
