Counts are what owners told NHTSA, as filed. NHTSA does not confirm each report, and a complaint is not proof of a cause. Injuries: 16. Deaths: 2.

Complaints by area

Each bar is the share of this model year's 254 complaints that name that area. A complaint can name more than one area, so the shares add up to more than 100%.

13 smaller areas not shown (57 complaints in total).

Do not compare models by these numbers. NHTSA has no sales count for each model, so a model with more complaints may just have sold more cars. Use them to see which areas owners write about, not to rank cars.

Common repairs in this area (not a diagnosis)

These are repair jobs that sit in the areas owners report most. A complaint may need a diagnosis first: the same symptom can come from many causes, and a serious one such as engine failure is not fixed by a cheap part. They are not a forecast of what your Elantra will need. Ranges are US estimates for all makes.

This model year has an engine recall in NHTSA's data. Before you pay for an engine repair, check the recalls and ask the dealer about warranty extensions for your VIN. Those repairs can be free.
