You don’t buy a 2024 Hyundai IONIQ 5 just because it looks like a concept car that escaped an auto show. You buy it to live with every day. So the obvious question is: how reliable is the 2024 Hyundai IONIQ 5, and what should you worry about if you’re thinking of buying one, especially used?
Big picture
Quick take: how reliable is the 2024 Hyundai IONIQ 5?
2024 IONIQ 5 at a glance
Pull those numbers together and you get a clear story: the 2024 IONIQ 5 is not a problem child, but it’s also not a Toyota Camry in EV clothing. It sits in the middle of the pack for reliability, with excellent crash safety and a very generous warranty safety net.
Who the IONIQ 5 suits best
Expert reliability ratings vs real owner experience
Reliability is part math, part mood. On paper, the 2024 Hyundai IONIQ 5 carries mixed but improving scores. Consumer Reports has pegged recent IONIQ 5 model years in the below‑average range for predicted reliability, while J.D. Power’s Quality & Reliability score around 70/100 is squarely "average" for an electric SUV. Third‑party outlets like The Car Guide give the IONIQ 5 a solid overall rating (around 81/100) but only about 5/10 specifically for reliability, noting that this is still a relatively new platform.
What the experts see
- Teething issues on a new platform: The e‑GMP architecture is new, so early software and electronic-module bugs are not shocking.
- Few serious mechanical failures: No pattern of motors or gearboxes failing in large numbers so far; most issues are electrical or software‑related.
- Excellent recall record: Aside from targeted software recalls and updates, the IONIQ 5 doesn’t have a long list of serious safety defects attached to it.
What owners report
- Plenty of owners log 30,000–60,000 miles with no major problems, just routine maintenance and recall visits.
- Others describe long dealer stays for ICCU failures (the integrated charging control unit) and 12‑volt battery problems, plus frustration with parts delays.
- A common thread: the car itself is often loved, but the dealership service experience can be hit‑or‑miss depending on where you live.
Reliability depends on your dealer, too
Common 2022–2024 IONIQ 5 problems to know
Because the 2024 IONIQ 5 is mechanically similar to the 2022–2023 models, it inherits the same strengths and a few of the same weak spots. Here are the themes that keep popping up in owner reports and complaint databases.
Most talked‑about IONIQ 5 issues
Not every car will see these problems, but they’re worth understanding before you buy.
ICCU failure & limp mode
12‑volt battery discharge
Instrument cluster / screen glitches
Infotainment & Android Auto/CarPlay quirks
Keyless entry security vulnerability
Cold‑weather range & charging behavior
Issues that can park the car
Recalls, software updates & service experience
As of early 2026, the IONIQ 5’s recall history is surprisingly clean for such a new EV, but it’s not blank. A software‑related recall in the early years addressed a potential roll‑away risk, and newer campaigns cover instrument‑panel software across several 2025–2026 Hyundai models, including the IONIQ 5. There are also technical service bulletins (TSBs) related to ICCU failures and 12‑volt behavior, which dealers use as guidance for repairs and updates.
- Early software recall for potential roll‑away due to control logic, typically fixed with a dealer software update.
- ICCU/charging‑system issues addressed through revised parts and updated calibration files.
- Latest instrument‑cluster software recall on certain 2025–2026 vehicles to prevent blank or frozen displays.
- Ongoing incremental infotainment and navigation updates, sometimes over‑the‑air, sometimes in person.
Hyundai’s warranty & maintenance support
The wild card is dealer capacity. EV‑specific parts like ICCUs or certain control modules may not be on every shelf. Some owners report three or four weeks in the shop waiting for parts, or repeat visits to complete multiple recalls because not everything was available at once. When you shop, talk directly to the service department about their EV experience and typical wait times, not just sales.
Battery life, high-voltage warranty & 12‑volt issues
So far, there is no widespread evidence of serious high‑voltage battery degradation in the IONIQ 5 fleet. These packs are proving stout, helped by liquid cooling and conservative management. You’ll see the usual EV pattern, some loss in the first couple of years, then a slower taper, but nothing that screams “run away” at this point.
Two batteries, two reliability stories
Understanding both the big drive battery and the small 12‑volt battery will save you headaches.
High‑voltage drive battery
- Covered for 10 years/100,000 miles under Hyundai’s EV battery warranty (longer in some CARB states).
- No pattern of pack failures or massive capacity loss in early years.
- Regular DC fast charging is supported, though it’s always wise to mix in slower Level 2 charging for longevity.
12‑volt auxiliary battery
- Behaves more like the 12‑volt in a gas car, and it’s been a known weak point in some IONIQ 5s.
- Can discharge unexpectedly if a control module or infotainment unit fails to sleep properly.
- Usually fixed with a replacement 12‑volt battery plus a software update or updated head unit.
How to babysit the 12‑volt
Safety & security: crash tests, theft risk and fixes
On the crash‑safety front, the 2024 Hyundai IONIQ 5 is a star pupil. It has a 5‑star overall rating from NHTSA and a 2024 Top Safety Pick+ from IIHS, thanks to a strong structure and a deep roster of active safety tech like forward‑collision avoidance, lane‑keeping assist, and available surround‑view cameras.
Security is more complicated. In Europe especially, thieves have exploited keyless-entry vulnerabilities to steal IONIQ 5s in seconds using expensive, Game Boy‑style key‑emulation devices. Hyundai has begun rolling out a paid hardware and software security upgrade in some markets to harden the system. In the U.S., guidance is still developing, but it’s worth asking a dealer (or a knowledgeable independent EV shop) what protections and updates are available for any IONIQ 5 you’re considering.
Security questions to ask
- Has the car received any security or keyless‑entry upgrades?
- Does it ship with both keys, and have those keys ever been replaced?
- Where was the car titled and garaged? Theft patterns can be regional.
2024 IONIQ 5 reliability vs other electric SUVs
If you’re cross‑shopping, it helps to know that many electric SUVs live in the same reliability neighborhood as the IONIQ 5. EVs avoid things like oil leaks and transmission failures, but they add complexity in software, sensors and fast‑charging hardware.

Exact scores vary by source, but the pattern is consistent: most mainstream EV SUVs are average at best for reliability so far.
The IONIQ 5’s reliability advantage
Buying a used IONIQ 5? Reliability checklist
A 2024 Hyundai IONIQ 5 can be a smart used buy, as long as you treat reliability like a homework assignment, not a guess. Use this checklist when you’re evaluating a car in person or reviewing an online listing.
Reliability checks before you buy a used 2024 IONIQ 5
1. Confirm recall & software update status
Ask for a printout of completed recalls and campaigns from a Hyundai dealer using the VIN. You want to see ICCU‑related campaigns, instrument‑cluster software, and any early software recalls marked as completed.
2. Review repair history for repeat visits
Multiple visits for “Check power system,” charging faults, or unexplained dead 12‑volt batteries are a red flag. One clean fix with updated parts is fine; a trail of repeat complaints is not.
3. Inspect and test charging behavior
At a minimum, plug into Level 2 and DC fast charging during your test drive. Watch for error messages, aborted charging sessions, or unusually slow ramp‑up. A healthy IONIQ 5 should ramp quickly and charge consistently once warm.
4. Check 12‑volt battery health
Have the 12‑volt battery load‑tested. If it’s original and the car is two or three years old, budget for a replacement. Ask whether any TSBs or software updates were applied to address parasitic draw or infotainment issues.
5. Evaluate infotainment and driver‑assist systems
On the test drive, spend time with Android Auto/Apple CarPlay, navigation, driver‑assist features, and the digital cluster. Look for freezing, reboots, warning lights, or constant beeping. Glitchy tech isn’t just annoying; it can hint at underlying module problems.
6. Ask about keyless‑entry security measures
Especially if the car is imported or has spent time in high‑theft regions, ask whether any security upgrades or key re‑programming have been done. Make sure both keys work, and consider adding your own physical deterrent, like a steering‑wheel lock.
