Crankcase (pcv) problems of the 2025 Chevrolet Equinox

This is a 2025 vehicle with 25,000 miles and the check engine soon light stays illuminated due to a faulty pcv valve or possibly a poorly designed crankcase. The engine code is p04fb and is commonly found as an issue when you do a search. As a safety precaution, the vehicle is programmed to not allow the remote start to work as designed when the engine light is on so this issue affects the overall functionality of the car. Having spoken with the dealership, they report seeing that engine code often and that the part is on backorder. The dealership seems to think it's the crankcase causing the issue and not the pcv valve as the fix they have been ordering for them is the case. It will potentially go away as the weather is hotter, but if a chilly night or morning comes up, then the light will come back on because there is moisture buildup on the pcv valve when the temperature drops that causes the light to come on. With all of the complaints I have read online for this very issue, I would like to see NHTSA step up and make chevy fix their problem. Thank you.
