2024 Hyundai Sonata Electrical System

The contact owns a 2024 Hyundai Sonata. The contact stated that while operating the vehicle the horn had become inoperable and no audible sound occurred while pressed. The cause of the failure was not yet determine and the failure was not yet repaired. The local dealer was notified of the failure. The manufacturer was not yet contacted. The VIN was not available. The failure mileage was 16,000.

I was sold a 2024 Hyundai Sonata SEL and while driving on the road multiple times the car completely shut off. By this all lights inside AND outside the car turned off (Headlights, interior lights and all) car was still rolling and I pulled over each time as all systems rebooted. It claimed that all seatbelts were off with the warning sign. Had to unbuckle and buckle all seatbelts for this warning to go away. Since the car completely shut off this put other drivers, my passengers, and myself at danger due to visibility. Luckily there was no traffic at the time but this keeps happening and it is worrying me.

This has happened three or four times now while I have been driving. While driving, my electrical system will "black out"/"power down"/"shut off." Everything on my dashboard turns off/goes black. My lights turn off. It is like my car shuts down for 2-4 seconds, then turns back on and I can continue to drive. There is no warning, sound, or anything. My car will just abruptly shut off. It is random too. There is no pattern that could help me determine what could be potentially causing this issue. It just happened again last night, while I was on the highway going about 70 mph. This could not only hurt me, but other people on the road. What if the next time my car powers down for a longer period of time? Who is to say what could potentially happen? I intend on scheduling an appointment with a Hyundai dealership to take a look at this issue. But I figured that because this has happened three or four times now, it will probably happen again, and other people are probably having this issue too. It could be a potential defect with the electrical system.
