If your OBD-II scanner displays a P0306 code on your 2022 Buick Envision, this code requires immediate diagnostic investigation because it references a cylinder that doesn't exist in your vehicle.
2022 Buick Envision Engine Configuration
The 2022 Buick Envision is exclusively powered by a 2.0L turbocharged 4-cylinder engine producing 228 horsepower. There is no V6 option available for the Envision. A 4-cylinder engine only has cylinders 1-4, making a P0306 (cylinder 6 misfire) code physically impossible.
Why You're Seeing This Code
- Scanner Misconfiguration: Wrong vehicle selected or auto-detection error
- Model Confusion: Scanner may be reading as Enclave (V6) instead of Envision
- ECU Communication Glitch: Data transmission error during scanning
- Software Issue: Rare ECU corruption generating invalid codes
Note on Model Names
Buick's "E" lineup can be confusing: Encore GX (3-cyl), Envision (4-cyl), and Enclave (V6) are all different vehicles with different engines.
