First welcome to the website.
There are many threads in the electric problem and interior problem section that has info on the problems you are having.
Most threads say to check for aftermarket electronics such as stereos, remote starts or alarms even a Range technology AFM eliminator in your diagnostic port. Then check to see how old your battery is and if needed have it load tested. Then check all of the grounds for the electrical system and then see someone with an electrical meter to check each circuit for any unusual power drain. Some say you can pull one fuse at a time and see if the drain goes away as a way of "process of elimination".
Good luck with finding the problem.
