I've had my Model S for about three weeks. I've been an obsessive researcher and sometime commenter here for about the last 6 months, though, so now it's time for my first post. I'm experiencing something kind of weird that I want to see if anyone else has encountered.
You know how if you're going fairly fast, like 60+ mph, and if you roll down one of the back windows, you get this pulsing of air pressure in and out of the car that kind of feels/sounds like an unpleasant throbbing on your eardrums? My wife is very sensitive to this, and windows need to either be all somewhat open or all the way up if we're about to get on the highway, and DON'T change them once we're going fast. Opening one at highway speed actually hurts her quite a bit. Bothers me a little too, but not much.
Anyway, so on to the Model S issue. With all of the cars we've had before, having all the windows up makes it a complete non-issue. The cabin is sealed enough that there is no air pressure pulsing at all. With the Model S, at various speeds, even low speeds, I get that pulsing from bumps in the road, even with the windows all up. I just went on a 600 mile road trip, and I found it to happen quite a bit, not on a regular repeating frequency, but timed on whenever the car would go over some kind of minor bump in the pavement. And this was with the windows all up completely. My wife has just recently gotten to ride in it some and brought it up unprompted, without me even mentioning it, and I concurred that it was something I had noticed. She said it is the one thing that she has found not perfect about riding in the car (Good Wife Approval Factor going on there).
Has anyone else heard of this air pulsing thing? Is it common on cars that have frameless windows, since they probably wouldn't air seal as well? I've only had one car with frameless windows before, and that was kind of briefly.
Edit: Found out that this was caused by the rear lift gate not fully landing on the stopper pieces. Bumps caused it to bounce, compressing the air. Implemented solution suggested in comments and it fixed it.
