Wind noise and buffering in Hyundai Palisade

[CVP33]

OK, once again I'm trying to find something qualitative. I downloaded a decibel meter for my iPhone8. Nothing fancy but at least directionally accurate. 3 cars tested 2017 Toyota Avalon Limited, 2019 Jeep Cherokee, 2020 Hyundai Palisade Limited FWD:

Methodology
1) Vehicle 1/2 throttle from stop to 65mph and then cruise.
2) Phone held next to my left ear halfway between my ear and side window.

2017 Toyota Avalon
- Peak 82 dB
- Steady @ 69 dB

2019 Jeep Cherokee
- Peak 88 dB (I attribute this to a really buzzy 4 cylinder)
- Steady @ 74 dB

2020 Hyundai Palisade
- Peak 78 dB
- Steady @ 71 dB

Sad to report that I now hear the wind noise but it's not objectionable. I definitely hear more road noise in my Avalon. My theory is that the other noises are so muted in the Palisade that the wind noise becomes the ONLY thing you can hear. Radio at low volume pretty much cancels it out. I am surprised though given the money spent on the limited for sound deadening glass and the triple seal door trim. It absolutely sounds localized at the upper rear corner of the door. Hope this helps someone.

I am getting the wind noise as well. I called the dealership and they said they couldn’t don’t anything until Hyundai tells them how to fix the issue. It is so annoying

We purchased Palisade Limited in Aug 2019 and noticed the wind noise on drivers side almost immediately. It is definitely not a normal noise, it starts around 45/50 mph depending on cross winds and we hear it all the way up to 70 mph. It sounds like a higher pitched leak in the gasket seal, almost sounds like some turbulence coming off the car somewhere. We noticed it originally even with radio on and it is annoying since the sound is right near the driver's ear. We come from owning Toyota's and Lexus' and never hear anything like it. This is our first time trying out Hyundai and it is a bit of a let down, considering pretty much everything else in the car is pretty nice. Makes you appreciate what Toyota/Lexus is able to pull off, they make it look so easy.

Thanks for the useful info and scientific study.

Has anyone find a fix? I have taken my car in three times to see if they can fix it and have no luck!! It’s super annoying. Also does anyone have a black spot at night from the head lights on the left side?

 

[Cfreedma]

Is anybody else experiencing a very loud wind noise on the driver side of the car at higher speeds. Mine is so loud it hurts my ears. I am going to take it to the dealer, but wondered if anyone else was experiencing it or took it into the dealer.

Has anyone taken it to the dealership and got a fix for it yet?

Yes, ours seems to be getting louder. Found that slight pressure with elbow on drivers window quiets it some, but difficult to drive like that.

 

[Dwallyn]

Mine is at shop. Haven’t heard if fixed or not. Will update

 

[Cfreedma]

I’m taking mine back tomorrow. If you turn your AC on high with fresh air you can replicate the sound!! The dealer is excited that I found this to help fix the problem. It doesn’t do it with recycled air.

 

[tallLeRoy]

I still don't have my ordered Palisade, but the symptoms sound to me like atmospheric pressure is rising in the car either from the vehicle speed or wind coming through the vent system. It may be that the noise you hear is from air escaping from the cabin, not air coming in. The pressure builds, the seals blow (making noise) the pressure stabilizes and the seals return to normal until the pressure builds again.

There should be vents somewhere on the vehicle to equalize the pressure with the outside air. On some other cars when the rear bumper cover is damaged or missing, I have seen the vents low on the rear fender. So is it possible that something is interfering with the operation of the vents.

If you have the noise, are the rear seats up or down when you have the noise.

Is the noise only present in Palisades with the power rear seat?

It sounds plausible to me,

LeRoy

Thanks for the info. I’ll show it to the dealership tomorrow and see if that helps them find the problem.

Dealer fixed wind whistling noise from inside driver window. Easy fix with adjusting the seals around window. Happy Palisade owner. Absolutely love this car

Did they replace the seals, or did they just adjust and re-glue the existing seals?
If this is the answer, then we need to know what to tell "our" dealers.
Thanks

They replaced my rubber seal and didn’t do anything. We think we figured it out and it has something do do with the vent. I have the head engineer for Hyundai working on it.

No replacing. Just adjusted according to the head tech engineer.

Joining the crowd with wind noise (and a faint whistle) that is progressively getting worse around the passenger door at highway speeds. Took it to the dealer and they deemed my noise as “characteristic of the vehicle type” (although it wasn’t there when I drive it off the lot). I ended up calling Hyundai customer service and they are reviewing my case.

After reading this forum I tried applying a little pressure to various spots on the passenger window and door with no help.

Does anyone know where the cabin relief valves are located on the Palisade? The post above mentions the cabin could be pressuring causing the seals to leak. This would make sense in my case so I would like to gain access to them and confirm they are venting properly.

If you get a chance, ask the engineer where the vent is located on the Palisade. Then tell us what they said.

I have been looking for a Palisade parts catalog on the web this afternoon to try and get a location, but I was not able to find one.

 

[tallLeRoy]

Found the vent, at least for the left side. I don't know if the right side has one too, but both the left and right sides have interior vents beside the rear seat back. You can see the vent position in this MotoMan YouTube video from the media introduction at time code 4:09. It is the rectangular hole behind the rear wheel arch. The vent is normally under the bumper cover. At time code 4:15 you can see that there is a pretty good size interior cavity there where the vent is located. I know that on Limited models the subwoofer is also in that cavity. I wonder if the subwoofer assembly is somehow restricting the left side vent.
