What he's not mentioning is that the carbon monoxide issue doesn't exist if the front windows are open making the whole cabin a pass-through for outside air.

You stated that rolling the rear-window down while driving creates a "tornado effect" and pulls the exhaust into the rear cabin area. Are you saying this occurs with ALL of the vehicle's windows in the down position? What combination of side windows - front and rear - open vs close will cause or not cause the "tornado-effect?" I am not an engineer, but it seems unlikely that rolling all of the side widows down, or even just the front side-windows down would not cause this issue. Seems like there would be a lot of complaints about this if that were true in those specific scenarios. Perhaps this only occurs when ONLY the rear window is rolled down?

You are correct. The carbon monoxide will only get sucked into the cabin if no other window is open. I wouldn't rely on the HV/AC system set to vent to do this.

Thanks for your update and I realize this is a sensitive issue but I use the roll-down often. I am retired now and not able to put items on the roof. I purchase lumber or possible a tree which extends a foot or two out the back. I flag the item. The window may be a show stopper for me. Thanks

I roll down the rear window almost everyday. This promotes good air flow thru the cabin without buffeting or the flow feeling too strong when I also have my side window down. This is the main reason I wouldn’t change to another SUV. I also enjoy access to the back when I have a long kayak on the roof, which is often. This is even more important on road trips to races.
