What is causing my Hyundai Tucson 2018 Electrical shutdown

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Oh no! That's no good and very unsafe! The issue could be related to a weak battery or a failing alternator, but since it restarts after a while, it might be more complex, like a faulty relay or an electrical short. Check the battery terminals and connections to ensure they’re clean and tight. Inspect the main fuse box for any loose or corroded connections. It’s also possible that a failing ignition switch or a problem with the vehicle’s anti-theft system could be causing these shutdowns. Given the unpredictability, I’d recommend getting it diagnosed by a professional who can check for any hidden issues in the electrical system.
