Transmission Noise problems of the 2013 Ford Edge

2013 Ford Edge limited awd 2 weeks before thanksgiving. . The vehicle was parked in our garage a few minutes after my wife got home from a 16 mile round trip to town. I heard a high pitch noise from the engine, performed a visual inspection and saw no problems. Assumed it was normal and that it would turn off on its own. Most new vehicles have a function to turn off any device before it drains the battery. The next day we went to start the vehicle and it was completely dead. Jumped it and my wife took to work. Worked fine the rest of the day. She got home and I heard the noise again. Checked it with battery tester and had a load on the vehicle and battery was already down to 75%. Took to local mechanic and he diagnosed as mechanism in transmission staying on and recommended dealer repair. Dealer misdiagnosed it as aftermarket autostart 2 times and charged me to replace the battery the second time. Finally on the 4th trip to the dealer, the malfunction happened while they had the vehicle. Dealer replaced mechanism in transmission, this did not solve problem. Dealer ordered drive train computer(waited over a month for part), this has not fixed the problem. It is now the first week of February(almost 3mnths later) and the vehicle is still at the dealer and they cannot find what is wrong with it. Someone please help!!!!!!!!!.

Part of the dashboard will madly change on its own going though the different options like it's stuck; the navigation display and dash board when starting the car will not always light up like it used to do. There is a delay at times. The ambiant lighting nomatter how many times I choose pink it always defaults back to blue on its own. My car has begun to make a horrible noise under the carriage, we suspect it is a transmission issue. It feels like the vehicle struggles to move forward. Just the other evening after leaving work, my interior overhead lights would not go off. Nomatter how many times I tried to turn them off. The electrical issue with the dash board began a while back and the noise just recently. The mileage on my car is 36,000 more or less. This should not be happening to our car. Well taken care of, I drive it to work and back. The car just turned in August 2 years. I have an appointment at the dealership this coming Tuesday. I believe my car is still under the power train warranty, I pray that it is. Just today, my vehicle would not lock as well. I will update as soon as I take it to the service dept.
