Hyundai Ioniq 6 vs Nissan Altima: Reliability Compared

Nissan Altima edges out the Hyundai Ioniq 6 on reliability. The Altima has a long record across nine model years, while the Ioniq 6 is newer and has charging unit failures that can leave it in limp mode. Both models rate good overall.

How Do the Hyundai Ioniq 6 and Nissan Altima Generations Compare?

Most used Altima shoppers will land in the sixth generation, which ran from 2019 through 2023 and got a refresh in 2023. A 2018 car belongs to the fifth generation. The weakest years, 2019 and 2020, were the first years of the sixth generation, and 2023 is among the strongest. The Ioniq 6 is in its first generation, which began in 2023 and got a facelift in 2025. Its weakest years, 2023 and 2024, were the launch years. Newer cars have had less time to collect complaints, so the later years need a cautious read.

Verdict

The Nissan Altima is more reliable than the Hyundai Ioniq 6, scoring 79/100 vs 77/100.

Edge goes to the Altima, and it is a slight one. Both sit at a good standing. The Altima has a long record across nine model years, plus independent repair-cost data. The Ioniq 6 draws fewer complaints per car sold, but it has only four model years on the road. Its charging unit failures can strand a car in limp mode or shut it down in traffic. The Altima's problems are broader and include more crash-linked areas, which keeps the gap small.

What Are the Common Problems With the Hyundai Ioniq 6 and Nissan Altima?

Four crash-linked areas set the Altima apart: electrical, service brakes, air bags, and steering. Reports include fires, tie rods that separate during turns, air bags that did not deploy in serious frontal crashes, and automatic braking with nothing ahead. Ioniq 6 complaints center on one part, the integrated charging control unit. A warning appears, speed drops to about 25 mph, and some cars quit in traffic. Only its electrical category has a crash-linked complaint, and just one. Its other issues are false emergency braking, a charge door that freezes shut, and a cracked windshield.

Best years to cross-shop: The 2024 Hyundai Ioniq 6 scored 77/100 and the 2023 Nissan Altima scored 84/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the Hyundai Ioniq 6 vs the Nissan Altima?

Pick the Altima if you want a car with a long track record and a known repair bill. Aim for 2023, one of its strongest years, and be wary of 2019 and 2020, its weakest. Run the VIN for open recalls, and test the automatic braking on a drive. Owners reported tie rod failures and false braking, so a clean inspection matters. Pick the Ioniq 6 if you want an electric sedan and can live with a young model. The 2025 and 2026 years look best, but they have had less time to collect complaints, so their clean record proves little. Avoid 2023 and 2024 unless the charging control unit has been checked or replaced. Ask for service records, because failures followed a software update in some cases and came back after a replacement. Parts can take weeks, so a breakdown could keep the car off the road. If you live where freezing rain is common, test the charge door.

Hyundai Ioniq 6 vs Nissan Altima: Common Questions

Is the Nissan Altima more reliable than the Hyundai Ioniq 6?
Slightly, yes. Both rate good, but the Altima has nine model years of history behind it. The Ioniq 6 has fewer complaints per car sold, yet its charging control unit failures can cut power while driving. The gap between them is small.
Which has more recalls, the Altima or the Ioniq 6?
The Altima has more recalls in total, with 20 across nine model years. The Ioniq 6 has 13 across four model years. Its recalls are packed into a much shorter span, so per model year it has more. Check the VIN for open recalls on either car.
Which costs less to repair?
Only the Altima has repair-cost data here, so a direct comparison is not possible. It runs about $483 a year, with 0.3 unscheduled shop visits a year and a 12% chance that a repair is major. Over five years that is roughly $2,415.
What is the main problem with the Hyundai Ioniq 6?
Failure of the integrated charging control unit is the main problem. A power supply warning appears, the car drops to about 22 mph in limp mode, and some shut down in traffic. The 12-volt battery often dies too, so a tow is common. Failures can return after replacement.
Do Altima owners report safety problems?
Yes, in several areas. Owners report fires, tie rods that separate during turns, air bags that did not deploy in serious crashes, and automatic braking with nothing ahead. Air bags have the most crash-linked complaints at 18, followed by service brakes at 14. Check the VIN for open recalls before buying.
