Picked my car up today and my heart sank when I heard the odd birdlike whistling sounds when I hit approx 40 mph. At first thought it might be the stereo, but then did the speeding up/slowing down and it was definitely wind/speed related. Elated to see explanation of problem in the area of the plastic sailplane at forward part of window by one of members...will be exploring solutions including closing off the large gap in front of it or a small thin black round rubber to fill the small gaps. Was going to experiment myself by taping off areas with painters tape but the explanation forwarded seemed plausible so I'll let everyone know if I come up with a solution (retired auto engineer) Thanks all for contributing.

Dano,
Picked up a 2021 base 992 this week and experience the same wind noise. Has your filling those gaps around the plastic sailplane solved the problem?

My dealer tried to fix the issue by installing a new seal around the driver’s door, but it appears that the whistle is coming from the windshield.

My dealer reported this issue to Porsche USA, but Porsche USA will not address the issue, even though it is widely reported and experienced.

How disappointing is this on two fronts: wind noise on a 911, and the refusal of Porsche to provide a remedy?

Hi, does anyone experience a Wind Whistle noise when driving between speeds from 50km/h-115km/h. I experience a wind whistle(especially when it is a wind still day) and traveling constantly at this speed. When going over 120km/h it gets quiet again. The dealership has been very helpful in trying to resolve the issue, but with no success.
"I have the whistle when the top is down and all the windows are up at 50 to 55 mph. Rode with a technician and he heard the same. Their solution was to apply tape and trim to see if it changed the dynamic. 21st. It goes in for this, also blown passengers door speaker, M light appears intermittent, and clear bra adjustment ( lots of dust).

I never thought I would be happy to find so much annoyance - but here I am. 2021 C4 Cab and I have exactly this issue.

My local dealer's head technician went "what the f*ck - thats not right" when he drove the car with me. They claim to have done everything the could, but to no avail. Their "solution" was that I should to complain to Porsche Switzerland - which I did - only to be told "there is nothing wrong with your car".

I have a distinct difference when driving in "Wet Mode" - the whistling is almost not present.
Anyone have this?
