What owners wrote
1. Crankcase ventilation valve performance failed check engine light is on while driving 2. Smells gas from under the hood. Heard it's common problems
While driving, the malfunction indicator lamp (mil/check engine light) came on. After some digging this was caused by an OBD II code of p052e, which indicates a blocked crankcase vent valve actuator. This appears to be a manufacturing defect in these vehicles.
