simple fire fix
Why not have the fan shut off whenever the gas door is opened, if, in fact, the side fan is running and causing the issue? There is already a sensor that can provide the cutoff switch to the Body Control Module.

I bet that can be done with possibly on OTA update. However, I think the concern is if fuel spills in there even with the fan off, once you finish fueling up and pull away, volatile vapors would still get either sucked in from the fan or pushed in from forward motion into the engine bay.

I don't believe there is a fuel door sensor. There is a fuel door lock, but no sensor if it is open or closed. This was also mentioned in the sticky as a solution, but without the sensor, no go.

The easiest fix is insert the pump correctly, set it on low fuel pump setting, and stand there while it's fueling to be sure it shuts off. But if you set it on high pump and go into the quick mart to browse around and buy your Twinkie and the auto shut off doesn't work, it's no surprise to me that you've sprayed gas all over the place. Not long ago I was filling up and that exact thing happened to a car on the other side of my pump. I shut their pump off and reported the gas spill.

Because the fan running is not causing the issue, it's a massive amount of spilled fuel onto the radiator that's the issue. The running fan sucks it on into the engine bay, but the cause is the spilled fuel. How many fires have occurred without spilled fuel? How many times have fans run in normal driving? No, the solution is what GM and the NHTSA are working on and have declared, a diverter to not allow spilled fuel to get into the air intake in the first place.
