2021 Hyundai Elantra Exterior lighting Problems

“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.”

“I bought my car at McGrath Hyundai in chicago in May 2021. It’s been in their shop 30 plus times for various and repeated issues. As of late, over the last 6 months, I have reported to them and to Hyundai, my drivers side seat belt won’t retract properly and the high mounted brake light warning continuously goes off, a dinging, stating that there is an issue. Hyundai and McGrath repeatedly misdiagnosed and refused to fix these issues when they were first brought to their attention when under 60,000 miles. …”

I feel that safety was compromised for style and this is not acceptable. I have sent a letter to Hyundai Motors Customer Care dated Sept. 7th in this regard asking for a Hyundai sanctioned solution and authorization for selling dealer to correct situation”

“Daytime and night time running lights turn off and on randomly with brights engaging random as well. Turn signals not operating but intermittently and wipers not turning on intermittently. This Started in Nov 2025. First time dealership could get it in was Jan 2026, stated Multifunction switch was bad and covered under warranty, now not covered after getting it in 3.5 months later.
