Maybe it's like some women when they are relating a problem - they don't want you to "fix" it, they just want you to listen to them -

Anyone know what I should do? Cars naturally have holes to release air but this is not safe to drive in. I blasted the AC, closed all windows and closed my garage door with car off, hovered a cigarette around the bottom of car to see what made smoke move this most, and by far this bar had the most movement. I also put a little trees car fresher in my spare tire well and my whole car smelt like the "Black Ice" scent when I rolled the windows down. Any help is much appreciated. My chest gets tight when driving. This doesnt happen with a stock fp only high flow fp. Thank you!!



There are two vents behind the rear bumper (1 on each side of the car, covered by black flaps) that relive cabin pressure when the doors are closed (take the bumper off, open a door then close the door, you'll see the flaps move.) I suspect this and similar issues may be related to these vents remaining open, possibly in conjunction with any under car exhaust leak either due to a fracture or a bad/leaky gasket.



I recall mention of a TSB being put out by Subaru years ago regarding repair or replacement of these vent flaps to ensure they do not remain open when operating the vehicle.



See if you or your dealer can locate this TSB, and/or install an updated set of flaps and report back on if that fixes this issue.

Something does not make sense as newer cars are designed to have positive pressure inside the cabin. Opening the windows will change things as there can be outside air moving around the car depending on speed. But still air should not be coming in through the one way flaps in the back.

He has air bags, so very well could be something from the plumbing or wiring install, the compressor is usually in the trunk from what I have seen.

Found the TSB - apparently it was put out due to potential for exhaust to enter the cabin:
