My radio/xm/cd player is cycling through CD eject and CD load. There is no CD in the unit. This looping prevents the radio/xm capabilities from working. I’ve tried to load a CD - the drive won’t take it.

My 2010 buick lucerne has a high pitched noise (sounds like a faint hair dryer) coming from the vented battery in the back seat. Just bought the car, didn't notice the noise until the next day. Easy to ignore when the car is driving and the sound is drowned out from road noise but you can definitely hear it when the car is at a stop in or in idle. I figured out the humming is connected to the battery when I rolled up my window I could hear a difference in the noise so I traced the noise back to the battery under the back seat. I am wondering if maybe the vent hose needs replacing. The battery was installed just two years ago so I'm not sure if it could be in bad shape already.
I hear nothing when I shut the car off and don’t move restart it gage mover when I step on the gas dose you move while car is going
