last year I had my dealer look at my 2.7 for auto start stop issue and they replaced my battery but unfortunately not fixed. Although the system off the save battery message stopped showing up. Just to be on the safe side I tried to turn off as much things as I can to save battery like bluetooth, interior lights, .... also in hopes to fix the auto start stop. is my bluetooth draining my battery? I left the bluetooth on last night and the next morning I got the 'system off to save battery' message. do you leave your bluetooth on or off?

 

What is it when you state bluetooth? Phone, radio or assessories?

Either way it shouldn't be your bluetooth, I have never turn anything off except for the ignition which unless you leave your phone in your vehicles disconnects your phone. I have alot hooked up to my by battery and not once has it died sounds like you may have bigger issues than the bluetooth.

Good luck with trying to run it down, sorry for not helping more.
