In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Rear left door lock actuator has failed. Door will not open from inside or outside. There is no emergency release of any kind. This is a major safety concern as in the event of an accident occupants could be stuck inside the vehicle. This is a known issue with this model as well as several Hyundai/Kia models

1.What component or system failed or malfunctioned, and is it available for inspection upon request? -> While I was driving on the highway, All Dashboard was blacked out and can't driving at all
-
Oil pressured sensor went bad $2500 fix from dealer. In Korea this is a recall. The Genesis forums are full of complaints regarding same issue. The factory should cover this but the 10 year 100000 mile warranty does not cover it since it is considered an electrical part.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
