This is strange. All accessories if you leave them on will be shut down automatically after about 30 minutes. There is not much to drain your battery even if you manually leave your dome lights on. In other words, your battery should not die even if you leave the car in ACC mode for the whole day.
Hmm. Here's what occurred: Let me know if I may have a weak new battery or if you still think this is 'strange' & I should have it checked out. thx.
1) Car in driveway, I turned on ACC mode to roll down the windows - to air the new car smell out a bit. I do not remember if I turned acc off or hit start again, but engine was not running when I exited the car.
2) Exited the car with doors unlocked, windows down. I had the fob with me in my pocket. Heard the beep when I walked away but didn't think about it.
3) went on about my business at home.
4) 7 hours later, entered car to roll up windows for the night.
5) Nothing happened when I pushed start - no noise, the amber light on start remained constantly illuminated, the only dash light that appeared when I pressed start was the airbag/seat pretension light, nothing worked: break, air, In/Out lights etc.
6) I tried the fob, pushed start several times - nothing.
7) Next morning tried again, nothing. deduced battery died. Had it jumped, started up after about 5 minutes. left it running for 20 minutes. cars been fine since.
