Owner sentiment in context
ICCU failures and the 2024 recall: what it means
The most serious reliability story on the 2022 Hyundai IONIQ 5 involves the Integrated Charging Control Unit (ICCU). This component manages DC‑to‑DC conversion and charging for the 12‑volt system. When it fails, it can strand the vehicle or dramatically limit performance.
Drivers have reported symptoms like sudden loss of power while driving, “Stop vehicle and check power supply” warnings, and cars that won’t charge or power up. In many cases, the root cause is damage inside the ICCU that prevents proper charging of the 12‑volt battery.
Why the ICCU issue matters
In March 2024, Hyundai launched a recall campaign on roughly 98,000 IONIQ 5 and related E‑GMP EVs to inspect the ICCU and associated fuses, replace hardware where needed, and update software to reduce thermal and electrical stress during charging and driving. If you’re looking at a 2022 model, you want proof this recall work has been completed.
ICCU checklist for a used 2022 IONIQ 5
1. Run the VIN for open recalls
Ask the seller, or check yourself on NHTSA’s site, to confirm the ICCU recall and any related campaigns have been completed. Get documentation, not just a verbal assurance.
2. Look for ICCU replacement records
Ideally, you’ll see a dealer invoice showing ICCU and fuse inspection or replacement, plus a software update. This suggests the car has already had updated parts installed.
3. Ask about past “no‑start” events
Question the owner or dealer about any history of dead 12‑volt batteries, “Check EV system” warnings, or sudden loss of power. Frequent incidents are a red flag.
4. Test drive for confidence
On your test drive, look for warning lights, power loss, or strange charging behavior after a DC fast‑charge session. You shouldn’t see any EV system warnings.
Home charging and port overheating complaints
Another recurring reliability gripe with 2022 IONIQ 5s is charging port overheating during Level 2 home charging, especially at higher amperage (40–48 amps). Owners describe sessions that stop unexpectedly, restart, then fail again, sometimes accompanied by very hot charge ports and cables.
Hyundai’s interim solution in some cases has been a software update that reduces maximum AC charging current when the system detects high temperatures, essentially slowing charging to protect hardware. That keeps things safe but can frustrate owners who installed 40‑ or 48‑amp home EVSEs expecting faster recharge times.
Dialing back current as a workaround
- When evaluating a used 2022 IONIQ 5, ask how the previous owner charged, home Level 2, public DC fast charge, or a mix.
- If possible, charge the car at a 32–40 amp Level 2 station during your inspection and watch for interruptions or app alerts about charging stopping unexpectedly.
- Look for technical service bulletin (TSB) documentation related to AC charging or port overheating; it indicates the car has received the latest guidance from Hyundai.
Battery health, degradation, and long‑term durability
The heart of any used EV purchase is the traction battery. On that front, the 2022 IONIQ 5 has performed well so far. You don’t see large numbers of high‑mileage owners reporting severe degradation or pack replacements; most discuss modest range loss as the miles climb.

Battery‑health checks for a used IONIQ 5
1. Verify range at high state of charge
On a test drive with the battery around 80–90%, compare the estimated range to EPA figures (about mid‑200‑mile range depending on trim and wheels). Modest variation is normal; extreme gaps may warrant a deeper look.
2. Review fast‑charging behavior
If you can, visit a DC fast charger and observe the charging curve. The car should ramp up quickly and then taper; repeated early throttling or errors may hint at thermal or software issues.
3. Ask about frequent 100% charges
Occasional 100% charges are fine, but storing the car at full charge for long periods can accelerate degradation. Long‑term owners who charge to around 80–90% daily often see better battery health.
4. Request service history
Look for any previous high‑voltage battery repairs or unusual diagnostics. Routine maintenance only is a good sign; repeated high‑voltage interventions call for extra caution.
Warranty coverage on a 2022 IONIQ 5
One reason many shoppers are comfortable with a used 2022 Hyundai IONIQ 5 is the generous warranty package Hyundai offers in the U.S. Even in 2026, many original‑owner cars still have years of coverage remaining.
Key 2022 Hyundai IONIQ 5 U.S. warranty terms
Always verify exact coverage by VIN, terms can vary by market and ownership status.
| Component | Typical coverage | What it means for a 2022 model in 2026* |

Shopping a used 2022 IONIQ 5: inspection checklist
When you’re buying any first‑year EV, the key is to separate well‑sorted examples from problem children. Here’s a focused checklist you can bring to a test drive or pre‑purchase inspection.
Used 2022 IONIQ 5 reliability checklist
1. Confirm all recalls and TSBs are complete
Ask for a printout from a Hyundai dealer service department showing <strong>no open recalls</strong>, including the ICCU campaign and any charging‑related software updates.
2. Scan the service history for patterns
A single ICCU replacement that’s been resolved isn’t a deal‑breaker. Multiple visits for no‑start events, repeated charging complaints, or unexplained electrical work are reasons to walk away.
3. Test both AC and DC charging
If possible, plug into a Level 2 charger at 32–40 amps and a DC fast charger. Watch for abrupt stops, errors, or warnings in the car and app. Stable sessions are what you want.
4. Check infotainment and ports
Cycle the infotainment system several times, use navigation, and test every USB port, Bluetooth, and smartphone projection. Random black screens or flaky USB connections are minor but annoying reliability issues.
5. Listen for rattles and suspension harshness
On your test drive, take a stretch of rough pavement at moderate speed. The car should feel composed with only minor noise, not crashing or thudding from the rear.
6. Verify remaining warranty
Use the in‑service date and mileage to estimate remaining coverage. For many 2022s, some basic warranty may have expired, but <strong>EV component and battery coverage</strong> often remain, especially for original owners.
