This car is three weeks old and has been buzzing for two weeks of it. They told me that it was a part that had to be replaced involving the temperature unit. They said it would take a week to fix. Then I received another call saying that there isn't a problem and this is normal . What?! Are you kidding me? Im not keeping a brand new car that has a buzz noise inside the car. Is it me? Or does that sound completely insane to you.
