Key takeaway for shoppers
How reliable is the 2024 Hyundai IONIQ 6?
Reliability data is still maturing for the IONIQ 6, it’s a relatively new model that launched for 2023. Early survey data for the 2024 Hyundai IONIQ 6 shows below‑average predicted reliability compared with the typical 2024 vehicle, with trouble spots centered on electronics and electrical accessories. At the same time, dozens of owners report completely uneventful ownership through 20,000–40,000 miles. That split is why this car generates so much debate in EV forums.
- Electric drivetrain components (motor, reduction gear) have so far shown good durability.
- The big risks sit in electronic control systems like the ICCU (Integrated Charging Control Unit), 12‑volt system behavior, and some climate‑control hardware.
- Software glitches, screens, warnings, sensors, are more common than mechanical failures, and usually resolved by software updates or module replacement under warranty.
Why EV reliability feels different
Recalls and known issues on the 2023–2024 IONIQ 6
Before you fixate on one horror story or one glowing review, look at the hard stuff first: recalls and known design issues. Those tell you what Hyundai and regulators have already identified as real problems.
Key reliability pain points on the IONIQ 6
What’s surfaced so far on 2023–2024 cars
ICCU / power electronics failures
Several owners of 2023–2024 IONIQ 6s have reported failures tied to the Integrated Charging Control Unit (ICCU) or related high‑voltage electronics. Symptoms include:
- Warnings, loss of power, and the car slowing to a crawl
- Complete shutdown in traffic requiring a tow
- Extended repair times while dealers wait on guidance or parts
In extreme cases, people describe repeated dealership visits and long stays before a successful fix.
Charge‑port and charging behavior issues
Hyundai has recalled tens of thousands of IONIQ 6s built from 2023–2025 for charge‑port door hardware that can detach. Separate from that, some owners report:
- Overheating at the AC charge port limiting Level 2 charging speed
- Quirky behavior when using remote climate pre‑conditioning while plugged in
- Occasional DC fast‑charging hiccups that resolve with a restart or software update
Common 2023–2024 IONIQ 6 recalls
Exact recall campaigns vary by build date, but on a used 2024 you should ask a seller or dealer for documentation that the following have been addressed where applicable:
- Charge‑port door hardware inspection or replacement
- Software updates related to high‑voltage system protection
- Any campaigns addressing ICCU or 12‑volt system behavior
How to check a car’s recall status
- Grab the vehicle’s 17‑digit VIN.
- Run it through the NHTSA recall lookup tool or Hyundai’s owner site.
- Confirm that all open recalls are completed, not just "scheduled."
- Ask for service records that show recall work done.
If a seller can’t show completed recall paperwork, build that into your negotiation, or be ready to walk.
Don’t ignore power‑loss stories
Battery and charging reliability
From a high‑level view, the IONIQ 6’s battery pack and fast‑charging hardware are a strong point. It rides on Hyundai’s E‑GMP platform, shared with the IONIQ 5 and Kia EV6, which is known for genuinely fast DC charging and solid real‑world range. Most reported issues are around charge‑port hardware or control electronics rather than the battery cells themselves.
- Owners regularly report trouble‑free DC fast‑charging sessions at 200 kW+ when conditions are right.
- Some 2023–2024 cars experienced slower‑than‑expected Level 2 charging, sometimes traced to port overheating or software limits.
- A subset of owners have experienced 12‑volt battery failures in the 2–3 year range, annoying but typically covered and not unique to Hyundai EVs.
Battery degradation so far
What owners report: real‑world reliability
Run through IONIQ 6 owner forums and you’ll see two very different storylines. On one hand, many drivers report thousands of uneventful miles. On the other, a smaller but vocal group documents months‑long service sagas.
Patterns in IONIQ 6 owner experiences
From "zero issues" to long service stays
Majority: smooth sailing
A large number of IONIQ 6 owners report:
- 1–2+ years and 10,000–40,000 miles with no significant failures
- Only routine recalls and minor software glitches
- Strong range and daily‑driver comfort
These are the owners who say they’d buy the car again.
Minor but annoying glitches
A second group reports small but frustrating issues, such as:
- Random sensor warnings or ghost proximity alerts
- Door handles, windows, or horn intermittently not working
- 12‑volt battery replacements after a couple of years
Most of these are resolved quickly under warranty.
Small minority: serious failures
The smallest but most concerning group reports:
- ICCU or high‑voltage faults that cause sudden loss of power
- Repeated dealership visits without a clear fix
- Weeks or months in the shop awaiting parts or guidance
These are the cases that drive lemon‑law and buyback discussions.
It seems very random to have a problematic car or not. It’s definitely not a "bad" or "unreliable" car at all… Online, you’ll mostly see the people with the problems, not the 90% of people that don’t have them.
The dealership factor
2024 IONIQ 6 reliability vs. other EVs
If you’re comparing the 2024 IONIQ 6 to rivals like the Tesla Model 3, Hyundai IONIQ 5, or Kia EV6, it sits in the middle of the pack on reliability. It’s not at the bottom of the EV world, but it doesn’t clearly lead either.
How the 2024 IONIQ 6 stacks up on reliability
High‑level comparison based on public reliability data and owner reports as of early 2026.
| Model | Overall reliability picture | Common issues | Warranty strength |
|---|---|---|---|
| Hyundai IONIQ 6 (2024) | Below‑average predicted reliability; lots of happy owners, but a noticeable tail of serious electrical problems. | ICCU faults, charge‑port hardware, software/sensor glitches, 12‑volt battery behavior. | Excellent: 5 yr / 60k basic, 10 yr / 100k powertrain and EV battery for most U.S. buyers. |
| Hyundai IONIQ 5 (2024) | Similar pattern: mostly solid, with some ICCU/charging‑related complaints. | ICCU failures, charging quirks, some 12‑volt issues. | Same Hyundai coverage as IONIQ 6. |
| Kia EV6 (2024) | Comparable to IONIQ 5/6; shares platform and many components. | Charging‑related issues, occasional electronic glitches. | 10 yr / 100k battery and powertrain (for original owner). |
| Tesla Model 3 (2024) | Better powertrain reliability than early years; more issues with trim, paint, and infotainment. | Build‑quality issues, rattles, touchscreen bugs, service delays in some regions. | Shorter basic warranty; 8 yr battery and drive unit warranty with varying mileage caps. |
| Chevy Bolt EUV (final years) | Generally solid once early battery‑recall era passed; simpler older tech. | Battery recall on earlier model years; otherwise minor hardware issues. | 8 yr / 100k battery warranty; basic warranty shorter than Hyundai’s. |
Use this as a directional guide; specific vehicles can be better or worse depending on build date and maintenance history.
Where the IONIQ 6 shines
Warranty coverage and what it actually protects
One of Hyundai’s biggest selling points is its warranty. For a 2024 IONIQ 6 bought new in the U.S., you’re typically looking at:
- 5‑year / 60,000‑mile New Vehicle Limited Warranty covering most non‑wear components.
- 10‑year / 100,000‑mile Powertrain Limited Warranty (for the original owner) covering major drive components.
- 10‑year / 100,000‑mile EV battery and electric‑drive system warranty, with language limiting battery capacity loss to no more than 30% under normal conditions.
- Separate corrosion, roadside assistance, and emissions coverage depending on state.
Important note for second owners
What warranty helps with
- Battery pack defects and excessive capacity loss within warranty window
- ICCU or high‑voltage component failures not caused by external damage or modifications
- Most electronic control modules and infotainment hardware during the basic warranty period
What it doesn’t cover
- Normal wear items (tires, brake pads, wiper blades)
- Damage from accidents, flood, or improper modifications
- Abuse, lack of maintenance, or using unsupported aftermarket tuning
Warranty protects you from defects. It doesn’t turn every bad experience into a free repair, especially if the problem is intermittent or hard to diagnose.
Used 2024 IONIQ 6 reliability checklist
If you’re considering a used 2024 Hyundai IONIQ 6, you can do a lot to tilt the odds in your favor. Here’s a reliability‑focused checklist to run through before you buy, whether you’re at a Hyundai dealer, independent lot, or shopping online.
Reliability checklist for a used 2024 IONIQ 6
1. Run a full recall and service‑history check
Ask for the VIN and confirm that all recalls have been completed. Review service records for repeated visits tied to power loss, ICCU replacement, or unexplained warning lights, these are red flags.
2. Test DC fast‑charging and Level 2 behavior
If possible, plug into a public DC fast charger and a Level 2 station. Watch for normal ramp‑up, stable charging speeds, and no unexpected faults or overheating messages at the charge port.
3. Pay attention to warning lights and alerts
On the test drive, note any persistent ABS, collision‑avoidance, or powertrain warnings. Random false sensor alerts at low speed are annoying today, and could hint at underlying electrical gremlins.
4. Check the 12‑volt battery history
Ask if the 12‑volt battery has been replaced and when. A fresh, properly coded 12‑volt battery can prevent some no‑start or weird‑electronics behavior as the car ages.
5. Inspect tires and brakes for uneven wear
Uneven tire wear or warped rotors can indicate hard use or suspension issues. EVs are heavy; if an IONIQ 6 has been driven aggressively without tire rotations, you’ll see it here.
6. Verify remaining warranty and coverage transfer
Confirm in writing which portions of Hyundai’s warranty still apply to you as the next owner. Ask the dealer to print a warranty summary based on the VIN and in‑service date.
7. Get a battery‑health assessment
If you’re buying from a specialist like <strong>Recharged</strong>, look for an objective battery report, such as a <strong>Recharged Score</strong>, that measures usable capacity, fast‑charging performance, and cell balance instead of guessing from range alone.
