UPDATE.........

Well, it turns out that the cells have shorted out on the battery. I was getting a voltage reading at the terminals of 13.5V but when a load is put on it, it shorts out and makes all the electrical act weird. They said they checked everythng out and seems ok, but Im keeping the reciept just in case. Also, while it is there, I am having them fix the passenger rear door handle that someone broke (and didn't man up) under warranty. Unfortunately I have to pay for the diagnostics for he electrical issue 'cause it is not warranty related. I get it back tomorrow.
