It has not happened to me while driving yet, but I usually have the sound up while driving anyway. As far as start up, a couple times yesterday, but after a couple trips today it did not do it. I traded in a 2010 camaro for the Journey, I love it so far. Rides like a dream and it is getting pretty good gas mileage for a SUV. Very comfortable on the road and quite compared to the camaro. Of course if I ever want to play with a camaro I'll just drive the wifes.
