Complaints for the 2020 Hyundai Ioniq are spread across a handful of systems, with brakes and the electrical system each drawing the most reports. On the brake side, owners describe unexpected jolting or lurching when transitioning from a stop to acceleration, with the behavior appearing intermittently and worsening over time in some cases. Electrical complaints cover a range of symptoms, a failed charge controller leaving the vehicle stranded, an inoperative horn with no blown fuses, and at least one report of the vehicle stalling while driving, later diagnosed as an overheated battery. A small cluster of structural complaints rounds out the picture, though at just two reports those remain a thin pattern. One report describes a sudden loss of power steering response during a low-speed turn, with the steering wheel spinning freely while the front wheels lagged behind.
