Honda Accord

How Do the Honda Accord and Hyundai Ioniq 6 Generations Compare?
Verdict
The Hyundai Ioniq 6 is more reliable than the Honda Accord, scoring 77/100 vs 76/100.
Effectively tied. Both cars stand in good reliability territory, and neither earns a clear edge. The Accord draws far more complaints and recalls, but its record spans nine model years against four for the Ioniq 6, so the gap partly reflects time on the road. The Ioniq 6 looks cleaner per car sold, yet its main fault, integrated charging control unit (ICCU) failure, can drop the car into limp mode or shut it down in traffic. The real choice is which risk you would rather take: a long, known list of screen and braking complaints, or a short record with one serious power-loss pattern.

What Are the Common Problems With the Honda Accord and Hyundai Ioniq 6?
Spread versus focus separates these two. Accord complaints cover several systems. The touchscreen registers ghost touches while driving, automatic emergency braking clamps down with nothing ahead, and head gasket failures and cracked cylinder heads cause sudden overheating and power loss. Electrical, brake, forward collision, and engine areas all carry crash-linked reports. The Ioniq 6 problems center on one part. ICCU failure triggers a power supply warning, limp mode near 22 mph, a dead 12-volt battery, and sometimes a shutdown on the highway. Only one Ioniq 6 complaint is crash-linked, but the data is thin. A charge door that freezes shut after freezing rain is a smaller issue.

Who Should Buy the Honda Accord vs the Hyundai Ioniq 6?
Honda Accord vs Hyundai Ioniq 6: Common Questions
- Is the Honda Accord more reliable than the Hyundai Ioniq 6?
- No, they are effectively tied. Both sit in good reliability standing. The Accord has many more complaints, but it has been on the road for nine model years in this data against four for the Ioniq 6. The Ioniq 6 record is short, so it is harder to judge.
- Which has more recalls, the Accord or the Ioniq 6?
- The Accord has more. Federal recall records show 46 recalls across its 9 model years, while the Ioniq 6 has 13 across 4 model years. The Accord has been sold longer, so more recalls have had time to pile up.
- What is the biggest problem with the Hyundai Ioniq 6?
- ICCU failure is the biggest one. Owners report a power supply warning, then limp mode near 22 mph, and some cars shut down in traffic or on the highway. The 12-volt battery often dies too. Failures can return after replacement, and parts can take weeks.
- What goes wrong most often on the Honda Accord?
- Electrical complaints lead, mainly a touchscreen that registers ghost touches and ignores real input while driving. Dealers often cannot fix it. Automatic emergency braking that stops the car with nothing ahead, and head gasket failures, are the next most serious groups.
- Which Accord and Ioniq 6 years should I avoid?
- Avoid the Accord from 2018 and 2019, its weakest years. On the Ioniq 6, avoid 2023 and 2024. Years 2025 and 2026 rate strongest for both, but they are the newest and have had little time to collect complaints.
