Radio/tape Cd Player problems of the 2009 Jeep Grand Cherokee

Took our Jeep to the dealership after the key fob kept getting stuck in the ignition and wouldn't release. They said it was the win module that needs to be replaced and the key would have to be reprogrammed for that win module! well, since then, we've noticed that when we are able to get the key out (from hitting above the ignition to get it to release, or waiting an hour for it to eject on it's own) the radio will keep playing, so we have to turn it off, all of the dash lights stay on, it still dings if the door is open and acts like the key is in it after being removed. Now we're running into more issues while we're driving where it starts glitching and the computer makes all kinds of terrible scary sounds and has actually powered down on us! now the battery is dead and won't start even with a jump! most issues started out while in park and just trying to remove key fob, that lasted a few months and it still drove fine. Unfortunately, the issues have continually gotten worse and I'm afraid to drive it with my family since it powered down while driving down the street!.
