Hello
I have a Sonata 2010, when I drive on the highway, I notice a sound of air while I close the windows completely.
I noticed that the car does not have a cover under the engine. can the sound of the air come from there?
What can be the consequences for the balance of the car and the fuel consumption ?

The sound can be from a number of places. It could be the weatherstripping in the doors shrinking or cracked or door bent and not making a great seal. It can be the side mirrors, or even a hole in the body somewhere. Would need to do some more investigating to figure it out. can you locate the direction from the driver seat where the air noise is coming from?

depends on what kind of and how loud the whistling noise is. Even the brand new 2018 Soanta has some noise. Camry and corolla do better than Sonata and Accord on noise cancelling
