lights turning on and off while driving

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. When lights, radio, and clock randomly turn on and off in your Elantra, it's usually due to an issue with the electrical system. This could be caused by a loose or corroded wiring connector, a weak ground connection, or even a problem with the alternator. Electronics can flicker or shut off entirely if the alternator isn't supplying consistent voltage. Intermittent issues like this can be tricky to diagnose, so it may be best to consult a trusted mechanic in your area. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
