Original post from 7/19/17:

Hey all, just picked up my new 2017 JKU w/ hardtop a few weeks ago. When I drive around with all of the windows rolled up I get this terrible pressure in my head/ears almost like I am taking off on an airplane. I have never experienced anything like this driving. Checked tailgate vents and freedom panel alignment and everything looks ok. Has anyone ever experienced or heard of something like this? Thanks

Update 7/30/17:

Hey all, just an update on my original post. I have NOT found a solution to why my Jeep Wrangler is making my ears pop and giving me headaches. I installed Hot Headliners and Sound Assassin strips - they look great but did not help much. I brought the car to the dealership on 7/19/2017 and they acknowledged that what I am experiencing is a problem and is not normal. They have been "working with Chrysler" to try different things that would eliminate this buffeting issue. Today is 7/30/2017 - The dealership has had my car for 11 days and the only news I have heard is that they dropped the tire pressure to see if that reduced the buffeting. The advisor tells me that at this point they think I am hearing the noise of the tires (absolutely not), yet he still admits that after dropping the pressure the problem is persisting. This Wednesday will mark 14 days with no solution. I really don't believe they are going to fix this problem. I believe I have 2 options - continue this egg hunt for a fix on my own, or try for a brand new vehicle/lemon the car. Anyone have any thoughts on this unique case? BTW the car only has 300 miles on it.....

So this is where I am really not sure what is going on. The problem is 1 of 2 things or maybe both. When I go over bumps I get a buffeting noise similar to having a back window rolled halfway down on the highway (the cause is the hardtop reverberating over bumps and causing low tones). To try and combat that vibration I put in the hot headliners (didn't help much) The second I guess could be a air leak. When I put the air on full-time blast with the windows rolled up and feel around the doors/hardtop there are a lot of spots leaking air. It does seem more tolerable driving with the windows down. At the end of the day I am not an engineer, so Jeep needs to be the ones to figure this out and make it right. Hoping that getting rid of the car is not the fix, however the problem literally makes the car undriveable - and I think Jeep realizes that.

Jeff,

I also just noticed that you have the Big Bear edition. I have the same. Do you find that you get some low tone reverberation specifically relating to the hard top when driving on bumpy roady? The noise sounds almost like a bass speaker and has the same effect on the ears as driving with just the back windows rolled down..

Going out on a limb here, but is the hard top tightened down? Missing any bolts? I have a 2014 Sport hardtop and have never felt any buffeting or experienced hardtop movement or reverberating. Door/hardtop seals all properly in place, not pinched or deformed? If it's more tolerable with the windows down, it's certainly not an air leak. Maybe take it to a reputable tire shop just to make sure everything IS correct related to alignment balance and so forth.

2012 Jk also has same pressure
Matt,

Do you experience that pressure under the same circumstances - Windows rolled up? Do you just live with it or are ya looking for a solution? This is honestly the dumbest problem ive ever had to deal with on a car.

Hey SG - The hard top is tightened down tight but not too tight with no missing bolts. I will say that when I took the hard top off to install the headliners it was difficult to put back on. The front passenger hole by the freedom panel did not line up correctly. I had to have someone apply pressure while i put that bolt in place. Maybe an alignment issue..I will pass that word on to Jeep dealership this week

Actually, my Jeep Liberty used to do this same thing, so I don't know that it's a hardtop issue.

In the short period that I had my 2017 Wrangler with a hardtop, I noticed that the seals were so tight on the Jeep that you literally had to slam the doors to make them shut tightly. In fact, the pressure was so high in the vehicle that you could press the door panels in and out like they were spring loaded. You couldn't do that if windows were down.

Since it feels more tolerable when you drive with the windows down my guess would be that you create high interior pressure when you jump in and close the door with the windows up. I'm betting as the seals age and wear with use, your problem might resolve itself. Not a big bet, mind you - maybe $3.00

It sounds as if you have two different issues you are trying to solve - air pressure and buffeting.

Air pressure, there is a vent in the tailgate but it is more of an over pressure vent. Later year TJs had a similar vent. If you run your A/C with outside are (recirc off) it will build slight positive pressure in the cabin. If you run it in recirc it will run slight negative pressure in the cabin. On my TJ with the soft top, if I run the A/C in the recirc position, I the soft windows will suck in and the top will be slightly loose (and tend to buffet). If I run it in the outside air position, it will push the soft windows and top out and no buffeting.

A hard top should not buffet. I wonder if the Freedom panels are on correctly and not too tight or too loose. You might have them take the Freedom panels and the hard top off and reinstall carefully and see if that helps.

I agree there are two issues as well. The hard top reverb happens when I am on a bumpy road, it is just abusive on the ears. I can actually hear the hard top reverb when I slam my driver door shut. The reverb is coming from the center of the hard top that has no support. It is acting essentially as a big drum. Did notice that the alignment was off when I put the rear hardtop back on. I had to have someone push in on one side to get the bolt to line up with the front holes. Maybe the alignment being off is somehow distorting the roof and causing reverb.

As far as air pressure inside the cabin I really don't know much other than - it doesn't seem to make a difference if recirculation is on or off. The air vents in the back are working properly. I have very carefully reseated the freedom panels with no luck. I checked around the hard top for air leaks and there are several. In Jeeps hands right now. I figure if they say they can't fix it I will press them hard for a new vehicle...

I have the buffetting issue on my JKUS Hard Top - but occurs at higher speeds.

It sounds as if the car next to me is blaring the bass as loud as can be. With that said - if I have my kids push on the hard top roof from the back seat when on the highway, the sound goes away.

I swore is was drive line related, but, thankfully, or maybe not so much, it's the hard top. All 4 windows down or the freedom tops off, and the noise goes away :)

Hey 0REDSOX7,

Let us know if we can help you make an appointment at the dealership to have this addressed!

Strangely enough, I just noticed this same cabin pressure phenomenon in my jeep today. It hasn't done this before.

The only thing I can think of is, I just installed the cabin air filter yesterday. Coincidence?

Do the rest of you guys who experience this have Auto climate control or have added cabin filters yourself?

Hey Andrea,

Thanks for the post. My car is still at the local Jeep dealership as of today 7/31. I will wait until Wednesday 8/2 to give them ample opportunity to fix the vehicle and then escalate if needed. Thanks again.

Do you have a hard top?

Maybe the hardtop is too thin, or some fiberglass/resin compounds are not mixed right in manufacturing, compared to engineering specs. The dealership should try changing out the hardtop.

I find I very interesting that you have a 'pressure' issue with your jeep. I say this because my wife has the same problem in every vehicle that she rides in. We have to have 2 windows down 1/2" for her to ride in the car. she also has more issues at higher altitudes. I did not know other people experience the same issue. I don't think her problem is any worse in the jeep though.

As far as the 'drumming' sound, I also had that problem with my 2016 hardtop. Putting the sound deadening insulation on the roof did nothing for that problem. I took a shower curtain rod and propped it across the bed of the jeep pressing against the plastic sides (about the middle of the window, in that section between the glass and the bed). It worked well, but was always in my way. I later replaced my stock wheels with 35x12.5x17 all terrain wheels and the drumming sound went away. I have no idea why that worked, but it did.
