Extreme Vibration - Rear Windows Down

[Michael D Morris]

I was driving about 35 mph yesterday in my 2019 Expy Max and I fully opened the rear windows to get rid of a gasoline odor that I had from a gas can that I was taking home. The front windows were up.

OMG ! the entire vehicle started shaking like a wheel was coming off. If all four windows were down the vibration went away. Has anyone else experienced this? Please try it while you are out and let me know if they all do this. I never heard of a car where you can't put the back windows down w/o the front being open.

Yes, mine is the same and it is annoying. My 2001 would kinda sorta do the same thing in certain cases, but nothing like Max does. I used to pop the rear side windows to alleviate it in the '01. Just something with the wind rushing past an open window to a sealed chamber. I wish they coulda put in something like a 1-way vent flap in the body somewhere to prevent it.

I usually vent the sunroof and it helps.

I’ve had this issue with other vehicles as well. I find that cracking the front window about an inch helps.

It is annoying, mine do it and so does my Explorer. Wonder if it's because the side glass is almost straight up and down.

Yep. Most of the vehicles I have owned have had the helicoptering noise. Crack a front window. Problem solved.

You can also open the rear body vent windows.

The owner’s manual for my 2015 has a notice about this concern - your manual probably does too.

These don't have rear vent windows, FYI.

Wrong generation. This is the Gen 4 forum. No rear vent windows.

Why open them fully?! Do you think it makes a difference for venting out the fumes if they're open 100%, versus say, 20%?

On a side note - has anyone driven with the tailgate window open? I had some gas cans in the back the other day and was tempted, but worried it would damage the heated window connector, or worse, shatter the window somehow.
