I'll give it shot:
Kiddies leave an interior light on you don't know about? Aftermarket electronic gear installed? A battery 2 months old, if in good shape when purchased, should be able to withstand a drain for 12 hours, at the very least. Are you experiencing any others electrical problems?

Hmmm. The only bit of advice I can offer now is to go back to the dealer and tell them. If it was fine before taking it in for the dsc controller, then they may have done something. If the radio gear was just installed, I would contact that shop and tell them. Somebody did something to cause the grief.
Good luck and please post back on the outcome.

If the dealer does replace the battery for you I would still take it to the stereo shop, tell them the problem and have them check it out.

A very easy and inexpensive way to pin point the location of the electrical draw is as follows. Disconnect the negative battery cable from the battery, take a basic 12volt test light and attach it inbetween the negative cable and the battery terminal. It does not matter whether you clip the alligator end to the post or the cable as long as the clip is attached to one and the needle attached to the other. Basically you are just using the test light as jumper. Once this connection is made, the test light should definitely have a good glow to it. There will always be a faint dim glow even on a normal working electrical system. So once you see the glow, go to the fuse box location and pull one fuse at a time. If after pulling the first fuse, the light stays on, put the fuse right back in and proceed until the light dims or goes out completely. Once this occurs, find out which fuse that circuit is protecting and you will have the problem location pinpointed. It will save you alot of diagnostic money at the dealership. Feel free to write back after finding draw location and I may be able to help from that point. Good luck.
