Now that the weather is getting cooler, my 2015 Genesis has developed a mysterious creaking noise coming from the front passenger seat area. I'm not sure what causes the noise, but the noise only comes when the temps are in the 50s or lower. It will generally happen while the body of the vehicle is flexing while driving. In addition, if the car is left in the sun and is warm, the sound is gone. Any ideas what it might be? I've linked a video below.
