Radio/tape Cd Player problems of the 2013 Ford Flex

The sync system stopped working and unable to find the error or issues. Searched internet and appears to be common issue with vehicle. The radio would make a glitching sound and then continue to play until it completely stopped about 5 weeks ago. The vehicle was parked and when attempting to start car the radio was dead.

2 issues 1) the front passenger door though closed is read as a warning "door ajar". The warning stays on at all times. It drains the battery and I have replaced the battery once since owning the 2013 Ford Flex when purchased in 2016 with just under 20,000 miles on it. The interior lights stay on from starting the engine until accelerated speed. The interior lights after parked stay on for a minimum of 30 minutes though it could be longer contributing to draining the vehicle battery. 2) the vehicle began to feel as if it is pulled while in commute. Not starting right away or shuts down/stalls. It has stalled and not turned over though the lights and radio work. Fortunately this has happened after being parked in my parking spot. It will not turn over, but the next morning it will start. After reading about similar issues for other Ford Flex vehicles last week with my vehicle doing the above action I replaced the fuel pump relay module. Which is located in the rear passenger area between rear passenger door and furthest rear window where the seat belt pulls from I felt I had resolved the issue. However, a week exactly later I attempted to start my vehicle when the exact scenario happened all over again. Vehicle would not start, but lights and radio worked. Left alone overnight I went to start it this morning and it starts. Through out the duration of this issue of stalling, not starting, pulling while in motion as it feels like the vehicle is being jerked there is no check engine light or when checking system the only warning is passenger seat ajar.
