Decided to post this for the people who do not know. The rear doors can be opened in the event of a power failure. Under the rear door mats there is a small square. Pop that square and there is a wire cable that can be pulled to open the rear doors. I took the square off mine as it needs something to pop it open. I just put the rubber mat back down to cover over the open square. Hope this helps some people, or gives them peace of mind! The owners manual no longer shows this. Confirmed they are still there on a Feb 2021 build.
