JLC. You might be on to something. They did engineer vents to relieve the pressure from this in the rear area where the compartments are in the back corners. They have scupper flaps on them to keep air and water from coming the other direction. However, no where near as much pressure relief as an open window. An example is to release the rear hatch with the button on the dash, then close the front door. The hatch will lift slightly from the pressure, then latch in the secondary position. You might think that the button didnt work..... I wonder if slamming the doors would make them fail prematurely too considering all the plastic being used
