Common complaints for Hyundai cars mention after-sales care, build quality and engine issues as of 2015. As with any car manufacturer, absolute quality and reliability are difficult to maintain with such high production levels, and practically every aspect of Hyundai cars receive at least some complaints.
Each year and model of Hyundai is very different, but looking at its mid-priced, mid-size family sedan option, the Sonata, there are issues that have been reported consistently over the years, and several of these have resulted in factory recalls. One example of this is from between 2011 and 2014, when the engine seizing was the most common complaint, according to carcomplaints.com.
Another type of common complaint addresses build quality in general. Since the introduction of the fourth generation Sonata, this has improved, but there are still many complaints for any car pre-2011, and the 2013 model had several serious issues with internal accessories.
The last of the three common complaints is the ongoing issue with customer care in the after-sales market. This is not just a Sonata issue but seems to effect customer satisfaction across several models. The issues include problems with parts being on backorder, making it very difficult to maintain the warranty for the car without having to wait long periods of time.
