The vent in the back has slats/gaskets that are supposed to only allow air to escape out from the Jeep and not allow air in. It is there for 2 reasons...1) air brought into the cabin through the HVAC needs to exhaust somewhere; 2) Allows air to escape when you shut the doors with the windows closed. You do not want to have an opening in the rear of the Jeep where gas can come in because the exhaust swirls up around the tailgate at speed and you do not want that CO coming in. If you are going to leave the hatch glass open, crack or open a window so that you have airflow going out.

Back to the OP. Depending on the terrain is what I would saw. I've had my jeep for 6 years and when I have the top on, I usually leave the glass up when I'm driving around town. Never had shock issues.
