Having problems with your 2008 Hyundai Sonata ?
On an unlit cottage road, I noticed that my headlights on my 2006 Sonata V6 dimmed for about one second on an infrequent basis.
As a precautionary measure, I would suggest taking the car to an autoparts store and have the alternator output and battery condition checked. Most parts stores offer this service at no charge. Sometimes dimming headlights can be caused by voltage fluctuations. Hope this helped and best wishes.
