Car Will Not Start problems of the 2017 Hyundai Santa Fe

My car wouldn't start had my car for service. I was charged a service fee which they would tell me whats wrong with the car. I was only told the battery was an issue. That was replace. The person who attend me did not tell me anything about getting an oil change or any other problems in February. Went back in April because my car stop running turned off in the middle of the road. Went back to the same dealer I not fix cars so when I get servive for the vehicle. I would think someone would tell me otherwise but no. I toke it back I was told the vehicle doesnt have warranty. That it expired but in the system there was no warranty even recorded. Now I am stuck with harassment calls about a vehicle I no longer have due to lack of maintenance. I purchase the vehicle last year in June 2019. I didnt have the car for then a year.

Navigation screen does not turn off after the ignition is turned causing the battery to drain and car will not start.

This is the third occassion where my 2017 Santa Fe will not start. When I turn the keys in the ignition there is no sound at all, no electricity is being sent to start the engine. However, all my lights and radio funtions work just fine. After a while the it will work again. My battery has been tested and shown to be working fine. I leave no interior lights on and cant figure out what changes to make it start working .
