Share of each model's own complaints, with the count beside it. "Most in" links to the symptom sheet for the model year with the most reports of it, and the mileage is the median from reports that gave one.
When problems start
Problems show up at about the same mileage on both. Half the Ioniq 5 complaints that give a mileage come before 20,000 miles, and half the EV6 complaints before 22,000. 88% of Ioniq 5 reports and 76% of EV6 reports come before 50,000 miles. Older model years have had longer to reach high mileage, so a window that runs to recent years pulls both medians down.
