2003 CTS. Battery keeps going dead
 

I am new to the forum and have a question. My CTS v6 doesnt seem to want to ever run. I have replaced the battery in it 2 times and it is constantly going dead if i dont drive it for a few days. I know that the battery is being charged properly while the car is on. But i dont know what is draining the battery. No interior lights are on. Nothing is on that is visible when i turn the car off. Has anyone heard of this problem before?

Thanks

Yes, but it needs to be checked to find the cause of the drain.
It's usually one of the on board computers not powering down.
Which one ??? How comfortable are you with a DVOM and do you have access to the vehical wiring diagram?
Otherwise i would suggest letting the dealer find and fix the problem for you.
