The radio in our 2017 Traverse is playing intermittently when the door is shut. Of course, the dealership is having trouble reproducing the problem. They know it is happening because it happened at the dealership. We are having problems with the battery draining and all other systems check out OK. But now they need to know which switch is the problem and if they can't reproduce the radio playing when the car is sitting with the doors shut, then they say they can't fix it. We also can't afford to keep putting $200 batteries in this car!

Has anyone had this problem or found the solution? Can someone please point us in the right direction?
