Tail Light Switch problems of the 2017 Hyundai Elantra

My car was parked and all of a sudden I noticed the headlights and tail lights turned on. There was an incident where I live that the fire alarm went off in the apartment building and I just happened to be standing outside and my car's exterior lights turned on by themselves. I had my key and I tried to turn off the car remotely, but the lights would not shut off. I had to go to my car, turn it on, and then shut it off. The same thing happened again the next day about the same time around 11 p. M. I did the same thing. Turned the car on and off and then shut it off and used the key remote to lock it. What is worse, while I was driving at night, I had my right blinker on to make a right turn, and I noticed the head lamps completely went dark when I turned and I didn't do anything, the head lights came back on by themselves. This is a very dangerous situation to be in. Please make note of this.
