I recently purchased a 2019 Accord 2.0T 10-spd and just the past three days i have noticed that when i start my morning drive the car makes a loud humming/white noise and gets louder and louder. I found that when the car comes to a stop or if i crack my driver window the noise immediately goes away and comes back once i close the window and drive again. It would go away after i got on the highway (5 minute drive) but After reading on this, i found a lot of other people are having the same issue and is only happening when its cold out. Well i live in Chicago so we have some pretty cold mornings, but i dont know why this would occur two weeks after i bought the car and not the next day. I read that other people think its the ANC and i agree with them, sadly i read people replacing transmission doing other things for the noise to go away, but i know 100% this is nothing engine or trans related especially since the noise goes away just from cracking the window and sounds like its coming from the center speaker. I have a appt made with the dealer and will relay what happens, but i wanted to reach out and see how many people on here are having the same issue
