It’s driving me crazy, I didn't have this problem with my 2017 Sport model, could this be coming from my sun roof?Many people with this issue.. My dealer replaced the small triangular window and the rubber weatherstrip around it. Improved the sound but not perfect, especially at interstate speeds (70-80mph).
coils the noise be coming from the sun roof,Yeah, likely other causes in addition to the window. I can hear it from the passenger side but the real problem is right next to my left ear since it is right next to the door. Many of us also have a condition where water collects in between the driver side rear door and the car body. The weather stripping is poor in this generation Sonata, especially compared to the previous gen PHEV model I had which I believe had additional strips to seal out wind noise from the doors. I have seen some aftermarket options to seal out noise and I might try that out. I don't think replacing will be the absolute fix and along with the hassle of scheduling the appts and dealing with dropping or waiting for my car, might have better luck solving this myself. Obviously not a huge issue because I noticed it from day one and still haven't gotten around to addressing it.
No idea if this works but seems like it is applied under the strip of the factory rubber on the body side.
