Hyundai IONIQ 5, which has surpassed 660,000 kilometers (410,000 miles) in total mileage, has made headlines. Introduced on the YouTube channel SuwaHosu, this vehicle currently holds the record for the highest known mileage for any IONIQ 5. The car has averaged over 600 kilometers (372 miles) per day in the nearly three years since its release.
What’s especially notable is that most of the vehicle’s core components have remained intact without significant issues. Aside from routine differential oil and brake fluid replacements, the car entered limp mode (emergency driving mode) and can now not charge via AC. This issue has been traced to a malfunctioning Integrated Charging Control Unit (ICCU), which requires replacement.
The most significant incident involved a high-voltage battery replacement. At around 580,000 kilometers (360,000 miles), Hyundai’s Namyang R&D Center replaced the battery free of charge. This exceeds Hyundai’s standard warranty coverage of 10 years or 160,000 kilometers (approximately 99,500 miles). According to the video, the battery retained about 87% of its capacity at the time, and although the exact cause or reason for the replacement wasn’t disclosed, some speculate that Hyundai may have retrieved the battery for analysis.
The owner mentioned that they primarily relied on DC fast charging and frequently charged the battery up to 100%. Despite this demanding usage pattern, the battery’s performance has remained relatively stable—an aspect receiving positive attention.
According to the U.S. Federal Highway Administration (FHWA), the average driver travels about 13,500 miles (approximately 21,700 kilometers) yearly. This case is considered an exceptional example of high-mileage driving compared to the average.
