The passenger side headlight has significant condensation inside the housing. The car is slightly over five years old, with 40,000 miles It was rarely driven the first year due to the pandemic. I have seen there is a TSB regarding the headlights, but clearly this is a far more significant issue than Hyundai is letting on. I was getting a warning on the dash but that has stopped yet the headlight is still covered in heavy condensation.
