I have a 2012 Chevy Cruze and sometimes the interior dome lights and the exterior headlights come on by themselves. I think it only happens at night but that could just be cause it's easier to see. Also the radio is suppose to play until you open the door with the keys out and sometimes it flickers on and off a few times. Any ideas?
You may simply have a faulty door switch that is turning on and off when it shouldn’t.
Check that all the doors make the interior lights come on and go off when you open and close the doors. You may also what to check the tailgate/trunk.
If one of them is not operating correctly then it’s switch may need replacing.
