2019 Hyundai Ioniq

Here is a comprehensive list of common issues and complaints for the 2019 Hyundai Ioniq, broken down by category and engine/transmission type.

The 2019 Hyundai Ioniq is a compact car available as a hybrid, plug-in hybrid, and all-electric vehicle. The hybrid model features a 1.6-liter GDI four-cylinder engine paired with an electric motor, producing a combined 139 horsepower and 195 lb-ft of torque. It uses a six-speed dual-clutch transmission (DCT). The plug-in hybrid uses the same engine, but with a larger battery for increased electric range. The all-electric model features an electric motor producing 134 horsepower and 218 lb-ft of torque. The all-electric model uses a single-speed reduction gear transmission. People appreciate the Ioniq for its excellent fuel economy, affordability, and comfortable ride. However, some common complaints include lackluster acceleration (particularly in the hybrid models), a somewhat bland interior, and limited cargo space.

Overall Summary

The 2019 Hyundai Ioniq generally proves to be a reliable vehicle, but like any car, it has its share of issues. The electric model can experience significant battery range degradation and expensive motor failures, while the hybrid suffers from transmission issues and occasional engine stalls. Electrical glitches and interior trim problems are also reported. While some issues can be resolved with software updates or minor repairs, others can lead to substantial repair bills. It is recommended to have a thorough pre-purchase inspection and to be aware of the potential costs associated with these common problems.
