Interesting thing happened the other day with this car in regards to how I prevent the high battery drain issue. With the car off, I left the passenger rear door open long enough for the cabin lighting to time out and go off. Doing so, my high battery drain prevention method no longer worked. In order for it to work, I had to leave the front passenger side door open with the car off long enough for the cabin lighting to time out and go off. Once the cabin lights timed out with just the front passenger side door open, my locking trick to prevent the high battery drain worked again. This car is designed just like an ancient Japanese puzzle box.
