2006 Hyundai Sonata, V6, automatic transmission. I've owned the car for a year and a half now without any troubles. Today while driving there was a sudden explosive noise inside the car as if something blew off. I am not sure what this noise could be due to. The car's ac/heater/fan were off. The car's battery is fairly new (less than a year with 5 year warranty).
Any ideas what that noise could have been due to?
