“the headlights in this model Kona keep burning out after 9 months or so. I have replaced them multiple times in the last 5 years on both left and right sides. I use glove to put in the bulbs and are very careful not to let my hands touch the bulb. I have never had this happen with any other car I have owned. I suspect an electrical system issue, or perhaps wiring, but that is speculation. I have not had this inspected by the dealership. The latest date of failure is listed below.”

NHTSA complaint #11699982, filed 2025-11

“Back up camera had not worked since purchase. It is now August been dealing with the dealership and Hyundai National with a case number and zero help to rectify this issue. It is not my fault the sales man who sold me this car left two days later. anyone I speak to at the dealership, is not there again the next week. even hyundai usa are consistently unable to even get a manger to call me back. This is unacceptable. at this point any warranty is expired, this car was sold with a faulty camera.”
