Battery drains with all electrical components shut off. If vehicle left sitting much over one week it will completely drain the battery to the point that it will no longer hold a charge. I've replaced the battery 5 times in one year and finally put a quick disconnect on the negative battery post. I've had Toyota look at it twice and they say there is nothing wrong.

Battery drains with all electrical components shut off if vehicle left sitting much over one week. After third visit to dealer, they replaced a wiring harness. The problem persists.
