Just returned from O'Reilys and the battery came back with no issues at all. I didn't even think about checking the DTC's while i was there so ill probably ride back up tomorrow. I woke up this morning and tried the panic button and everything works perfectly again, including the siren. The only time the siren doesn't work is when you hit the panic button after it goes through one of its episodes with the alarm system randomly going off. I was thinking, if it is a faulty siren then wouldn't that mean that the siren just wouldn't work sometimes but it wouldn't randomly trip the alarm (I could be wrong, you never know with these cars). Would the DTC's show my which sensor tripped the alarm if that is whats responsible?
