My brand new car makes a rythmic, almost like someones bass, when completely stopped. It only happens sometimes and there is no rhyme or reason to when it does it. Sometimes does it when hard braking or soft braking, sometimes it happens after sitting at a red light for 4 or 5 seconds. As soon as I accelerate it goes away. I can change gears and it continues but as soon as I press on gas it goes away. Of course when I take it to dealer it doesn't do it but sometimes it does it at every stop sign and red light I hit and sometimes it can go 3 days without doing it.
