Hello,I have this issue where for some reason my car batteries die after only two days of not driving.I have tried changing the car battery twice but the problem still persists. I suspect maybe the car radio which I changed from the default one to an android radio with a reverse camera.
Have you tried changing the ECM & PCM fuse? And leaving the terminals off for about 20 mins so everything resets. Then just drive around for a few miles so the car can learn your driving habits again. I'm having a few issues with an outlander myself. Hopefully it's just a fuse or 2.
In my case it was a ground error. I had the same Problem. After renewing and cleaning every ground connections the car works normal again! After over 1 year of seeking this solved my problem. An additional indicator for this are flickering lights in drivers cabin. Sometimes error was gone few days, then came back. New batterie didnt help. Now, while the grounds are fresh and new again, it was finally solved. In Germany this is called "Massefehler". I hope "ground error" is the right term for this. In germany my mechanic could fix this with a cost of round about 90€
Put car into reverse and it will no longer show on the radio but I can go into setting and see the camera and adjust it. It seems the radio just can't tell when the car is in reverse.
