Hyundai Ioniq 6 Years to Avoid

4 scored model years (2023–2026) · model average 77/100

Skip the 2023 model year. Its owners filed the most complaints, led by ICCU failures that drop the car into a slow limp mode and can shut it down in traffic. The 2024 is the year to buy, with noticeably fewer complaints, though the ICCU issue still appears there.

2023 Hyundai Ioniq 6

Owners of 2023 cars filed 54 complaints, the most of any year. Over half were electrical, mostly ICCU failure: a power warning, a limp mode near 22 mph, then shutdown, a dead 12-volt battery and a tow. Failures came back after replacement, and parts took weeks. Others lost power with no warning, or hit false emergency braking.

2024 Hyundai Ioniq 6

The 2024 logged 33 complaints against 54 for the 2023, and it has been on the road long enough for that record to mean something. It is not trouble-free. ICCU failures still show up, often around 25,000 miles. Newer years have had less time to collect complaints, so their lighter records prove less.

Frequently Asked Questions

Which Hyundai Ioniq 6 years should I avoid?
Avoid the 2023. It has the most owner complaints of any year, 54, and over half are electrical. ICCU failure, limp mode and sudden shutdowns lead the reports. The 2024 is the better used buy.
Is the 2024 Hyundai Ioniq 6 a good year to buy?
Yes, it is the site's pick. It has fewer complaints than the 2023. Still, owners report ICCU failures around 25,000 to 26,000 miles, often after cold weather, and two complaints allege unintended acceleration at parking speed. Ask for the car's ICCU history.
Which Ioniq 6 years lose power while driving?
The 2023 and 2024 both have reports of sudden power loss, mostly traced to a failed ICCU. The 2023 has more of them. Some cars slow to about 25 mph and quit, so a clean service history matters on either year.
Should I buy a 2025 Hyundai Ioniq 6?
It is a reasonable option but carries less history than the 2024. Owners filed 30 complaints, and electrical problems led with 15. It has 3 recalls in federal records. Ask for service records, especially on the charging and electrical systems, before buying.
Is the 2026 Hyundai Ioniq 6 the most reliable year?
It rates highest, but treat that with caution. The 2026 has no complaints and no recalls because it has had little time on the road. Older years have simply had longer to collect reports, so its clean record is not proof.
