Windshield noise above 50 MPH

We've had our 2018 GTS (CPO, 10K miles on the clock) for about 6 weeks now. I'm generally impressed, even though it wasn't my first choice of ride as I'm more of a sedan / wagon fan for our "practical" car, but it was my wife's first choice and she's the primary driver of it. I know I'm in the minority, but I just don't like SUV's or trucks, but sure love Porsche and have been driving them for over 20 years.

What I'm surprised about is how little chatter there is here about excessive wind noise coming from the windshield area at highway speeds, starting around 50 MPH. I found it so noticeable and unpleasant, I contacted my SA who had me bring the car back for their analysis. They found nothing wrong, AND my 2021 Macan S loaner car did exactly the same thing, so I guess it's just what they do. Our previous car, a 2016 Audi A6 was dead quiet as is my 2015 A4 "winter beater". My summer car, a 2015 Cayman GTS is also very quiet wind-wise, though the tire noise may just drown it out ;)

So, my question to you, Macaners, compared to other premium vehicles, do you find yours to be acceptable in the wind noise department?

I can go 100mph without much issues. I would actually like to go 160mph.

The only complaint I鈥檝e ever seen regarding windshield noise is when the replacement windshield was installed incorrectly. If there id any gap between the top of the windshield and the rubber trim that will generate noise. Other than that with side windows open you get buffeting noise that Is present in all new cars. Good Luck

By windshield noise you are referring to the buffeting noise that develops when the front side windows are down? If so I agree it's terrible. My '12 Jeep Grand Cherokee was bad but the Macan is worse. I think it's an issue that plagues a lot of modern cars, at least that's been my experience. The solution, keep the windows up with the climate control doing its thing.

I have two classic cars, both designed in the 60's when air conditioning was optional, and there is no problem with noise when the windows are down.

No, perhaps I should have been more specific. I'm talking about what it sounds like with windows and sunroof closed, fan off or low, no music etc. The amount of wind noise is truly shocking to me.

I'm not attempting to diagnose a problem, just amazed that more people aren't bothered by the vehicle's lack of refinement in this area.

Thanks! Mine did have the windshield replaced and the rubber gaskets / trim subsequently checked, but the fact that the new loaner did the same thing rules that out.

I was surprised to hear that noise too when I bought mine (same, 2018 GTS).
I found that it does it when the climate control is on with the fan low (one line). Once I increase it to 2-3 lines, the noise usually stops. I don't know if you have noticed the same

I don't get that at all. Maybe it's your tires. Mine came with Pirellis from the factory and there was quite a bit of tire noise. When I switched to Michelins the entire car became whisper quiet.

Def not tire noise. I know what that sounds like (like in my Cayman) and also where that comes from. It's the windshield.

I will play with that more. Thanks.
Put the a/c on recirc. That stops the a/c wind noise. I haven't noticed any excess noise in my 2015 S and I've been up to 140mph.

I have a 2018 GTS and I also find the wind noise unbelievable. My wife鈥檚 Mazda CX-9 is WAY quieter....
It鈥檚 like buffering around the side mirror or something?!?
I don鈥檛 notice any excessive wind noise from my 2020 S at UK motorway speeds (70 mph)
I have an S and just disabled music at 100mph to test this. I do not hear any unbearable noise And CX-9 is definitely not quieter.

Oh man, I wish. When I got mine I thought the window wasn't going up all the way or that I was missing a seal or something. Mine is crazy loud like I'm always in a wind storm from 40mph and up. I'm actually going to book a service appointment to get it looked at.

Are you sure it's not a wheel bearing? That's what was happening with my G35 back in the days right above 40mph. Or maybe your tire wear is uneven?
Haha, absolutely not, it's only got 17k on it. It's wind noise from around the drivers window/ mirror and I think the passenger one too...

Bummer. Good luck with figuring that out.

I have recently had my windscreen replaced after it was cracked, I now have wind noise which starts at around 45mph, the faster the car goes the noisier it gets.

Today by pure chance another Macan turned up at my house, it was the exact same year and model as mine, a 2017 Macan S. So I compared his screen fitment to mine as I had seen your post here a few days ago.

Sure enough his top rubber was a nice tight seal with no visible gap but mine has a gap both above the rubber and below, you can insert paper in the gaps.

My Macan is now re booked in to have it corrected, I suspect this will mean the screen needs removing to do this as it has clearly been fitted 2-3mm too low, does this sound right?

Top screen rubber shown here going from centre of the photo to top left.

Correct fitment in this Macan.

Yes mine was replaced after a crack and it was the seal not aligning just right. You can pinpoint the leak by opening your sunroof slightly as you drive to create a mild cabin vacum into which air will flow from the gap. You can seal it with clear variety "flex seal" .
