I just recently bought a 2016 Chevy Cruze LS and everything is good so far except for this one problem. When the car come to a stop, the car automatically turn off (auto stop feature) and then when I let go of the brake, the car turn back on but after the car turn on i hear this clunking noise (almost like a gear being shift or a knocking noise). This noise does not occur all of the time so I am assuming it is a problem . Does anyone know what the issue could be? so that when I call the dealership I can explain to them better. Thank you.
