Hyundai Sonata intermittent lighting issues with dashboard, interior, and headlights cutting on and off while driving on Hyundai Sonata

Some Hyundai Sonata owners report experiencing intermittent lighting issues, where the dashboard, interior, and headlights cut on and off while driving. This common problem may be linked to the headlight switch or an intermittent connection in the power line servicing the bulbs. The flickering and cutting off of headlights can pose significant safety risks, especially at night, for both the driver and other road users. Some owners suggest that this issue might necessitate a recall or technical service bulletin (TSB) for a quick resolution, similar to actions taken for the 2014 Kia Soul, which shares components with the Sonata. While experiencing these lighting issues, owners have noted that the radio may continue to operate normally. It is crucial for owners to address these problems promptly to ensure their vehicle's safety and functionality while driving, and consulting a qualified mechanic or Hyundai service center is advisable for effective diagnosis and resolution.
