How long does the vehicle sit, time wise, before the battery is drained?
You have a module in the vehicle that is draining the battery. They are supposed to power down after about 30 to 45 minutes after the key is turned off and all the doors are closed. We have seen the ACM (Audio Control Module) radio cause this. The radio will turn off and the display will go out, but it can still be on. Also, the instrument cluster is also a known cause. But do not replace anything. You will have to have a current draw test performed and remove one fuse at a time till the current draw is gone. You will need a digital multi meter to do this test and it will have to have an DC AMPS setting.
