A testament to durability, albeit with some very major repairs along the way.
The Hyundai Ioniq 5 has been a top-selling electric crossover since its launch due to its sleek styling, decent performance, and valuable features. Now, one incredible example is making headlines after it passed 413,992 miles (666,255 kilometers)—quite possibly the highest mileage ever recorded by an Ioniq 5.
Driven an average of 378 miles per day, this Ioniq 5 has endured a punishing routine over a relatively short span of just three years. While that usage would take the average American driver more than 30 years to achieve, it provides a unique insight into how well Hyundai’s E-GMP platform holds up under extreme conditions.

What Went Wrong: A Look at Repairs and Maintenance
Despite the incredible mileage, the vehicle has remained largely trouble-free. Still, a few key components failed or required replacement:
- Regular Maintenance
- Brake fluid and differential oil were changed on schedule.
- Notable Issues
- Integrated Charging Control Unit (ICCU) failed, currently preventing AC charging.
- Limp mode occurred once due to electrical system issues.
- Major Replacement
- At 360,000 miles, the high-voltage battery pack was replaced at Hyundai’s Namyang R&D Center—free of charge.
Interestingly, the original battery still retained 87% state of health before replacement. The owner reportedly charged to 100% frequently and used DC fast charging often, which typically accelerates battery degradation. However, this battery held up surprisingly well before being swapped—possibly as part of internal testing or for PR value, considering Hyundai’s standard U.S. warranty covers 10 years or 100,000 miles.
Is the Ioniq 5 Reliable Long-Term?
This high-mileage Ioniq 5 showcases the durability of Hyundai’s EV engineering, especially when maintained properly. While not free from issues—particularly the ICCU failure and battery replacement—it’s clear the platform is capable of far more than the average driving lifestyle demands.
Fast Facts:
- Battery Replacement: Unusual but done free by Hyundai, suggesting goodwill or data collection.
- Charging Issues: The ICCU failure limits charging options, but is repairable.
- Longevity: The vehicle continues to run and is largely functional despite a high-mileage life.
What This Means for Owners of Ioniq 5
For the average driver, particularly one who logs 13,500 miles in a year (as per the U.S. DOT), this type of mileage is nearly legendary. But it’s good to know that the Hyundai Ioniq 5 is holding its own even after 400,000 miles, with few catastrophic failures.
However, out-of-warranty repairs—like battery replacements—can be cost-prohibitive, at times venturing into the tens of thousands of dollars. Owners must factor this into long-term ownership, especially outside of warranty stipulations.
Finally, While not bulletproof, this ultra-high-mileage Ioniq 5 presents a strong case for EV durability, showing that with routine maintenance (and perhaps a dash of luck), an electric vehicle can last the distance—literally.
