In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
I was driving on the freeway when my car started smoking. Pulled over immediately and 30 seconds later the entire front of the car was engulfed in flames. I hadn’t received a second recall notice, but I did take it in the first time when a fire risk was mentioned.
-
Electric parking break and auto hold sensor lights on dash, manual indicates malfunction. Hyundai service center has investigated and replaced the faulty sensor but issue still remains.
-
The charge controller failed twice and one of the times I was out on a dangerous road where there wasn’t a safe spot to pull over. It was very sketchy.
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.
