Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 2 tested variants for this model year.
The dominant complaint pattern for the 2019 Hyundai Ioniq centers on vehicle speed control, where multiple owners describe the car accelerating or continuing to roll forward while the brake pedal is depressed. Several reports involve low-speed situations, parking or stopping at a light, where pressing the brake harder did not stop the vehicle. The electrical system draws the next cluster of complaints, with owners reporting the instrument cluster going blank or rebooting on its own, and a separate report of audible warning alerts, blind spot, rear cross-traffic, and driver attention sounds, becoming inaudible. A single report mentions airbags failing to deploy in a collision. Engine complaints round out the filed reports, though at low volume without a strongly recurring symptom pattern.

By System
The 2019 Hyundai Ioniq has 3 recalls, the most serious being a wheel separation risk where lug nuts were not properly tightened at the factory, allowing one or more wheels to detach while driving and creating a hazard for other vehicles.
This wheel lug nut issue affects both the hybrid and plug-in hybrid versions of the Ioniq, with one filing specifically noting the right-side rear wheel. A detached wheel can cause the driver to lose control and poses a danger to anyone nearby. The third recall affects electric models only: an unstable electrical ground can push the vehicle into a reduced-power mode, and in certain conditions while in that mode, the car can accelerate after the driver lifts off the accelerator pedal.
