GX Hybrid Crankcase Ventilation Issue

I had a similar problem with my GX. The ventilation system is complex. If you are seeing smoke, it's definitely not something to ignore. How many kilometers are on the odometer?

The vehicle currently has 234864 kilometers. Do you recall any specific error codes or diagnostic steps that helped pinpoint the issue in your case?

With that mileage, it is quite possible that it is a ventilation problem. Replacing it solved my issue. I'd recommend getting it checked at a reliable workshop.

I appreciate the confirmation and advice. I will schedule an appointment with a trusted mechanic to evaluate the crankcase ventilation system. I had the valve replaced, and the problem is resolved. The total cost was 360€ including labor. Thanks again!
