Scottie, my son found your date and now I'm hooked.  I bought a new 2015 Azura I'm the only owner. Never had a problem  with it untill a new battery  went in from the dealer, old battery  was 4 years old and just  died in the garage 1 day after driving it weekly. The new battery  after one week died on the 7th day 3 weeks in a row. Dealer checked the battery and  said there was nothing wrong  with it and gave it a full charge. Same thing happened  again on the 7th day. My brother charged  it and checked all the fuses and sensors under the hood by the battery  and after pulling each fuse out one at at time and checking for a spark at the battery  they tested goid. Something is drawing from the battery. Dealer said they didn't  get any bad codes on the machine when I brought it in. Does the battery  have to be dead while the car is at the dealer to get any bad codes? And doesn't  the computer reset if the battery is disconnected and then hooked back up? I'm at a loss on this, could a wire be grounding out somewhere and still send a code if the condition is right before the computer  resets itself.  What kind of a switch could be bad and how could it be found. Starting to have my doubts  about this dealer and could sure use some help.
