The Verdict

Consider

Rates good and above average among 2024 sedans, with fewer complaints than 2023, though ICCU power-loss failures and two parking-speed crashes stand out.

If you're comparing prices, check 2023 (redesign year) vs 2024+ pricing and recalls.

Should You Buy the 2024 Hyundai Ioniq 6?

Good, with one serious catch. Federal and owner records place this year above average among 2024 sedans and in the middle of the four scored Ioniq 6 years. The 2023 rates worse, with 54 complaints against 33 here. The 2025 rates about the same, with 30.

The problem that matters is sudden loss of drive power. Owners describe a loud pop and a "check electrical system" warning. The car then limps along at about 15 to 25 mph and shuts down, so it needs a tow. Dealers usually trace it to a failed ICCU. Failures cluster around 25,000 to 26,000 miles, often after cold weather, and some cars had the software update. Some cars wait weeks or months for repair. Two complaints also report unintended acceleration at parking speed, both ending in crashes.

Ask for the full recall record, which includes three electrical system recalls, and any ICCU repair history. Test the horns and check the 12V battery. A 2025 is a comparable alternative.

Compared to the 2025 Hyundai Ioniq 6, which scored 2 points higher. See also the 2023 Hyundai Ioniq 6 for an earlier comparison.

Used Buying Checklist

Key things to inspect or verify before purchasing a 2024 Hyundai Ioniq 6.

Ask for service records showing any ICCU replacement or software update, and look for repeat electrical failures.
Run the VIN through federal recall records and confirm every open recall is completed.
Have a dealer scan for stored ICCU fault codes and past "check electrical system" warnings.
Have the 12V battery load-tested, especially if the car has been sitting parked.
Test-drive soon after a Level 2 charge and watch for power warnings or a turtle light.
Press the horn several times and confirm it sounds every time.
Move the turn-signal stalk through its full travel and feel for cracking, looseness or sag.
Check that the steering wheel is centered on a straight road and inspect the rear tires for outer-edge wear.

ELECTRICAL SYSTEM

14 complaints

Sudden loss of drive power is the main report, and dealers usually trace it to a failed ICCU. A loud pop and a "check electrical system" warning come first. The car then limps along at about 15 to 25 mph and shuts down, so it has to be towed. Failures cluster around 25,000 to 26,000 miles and often follow cold weather. Some hit cars that owners say already had the ICCU software update. The 12V battery can also die while the car is parked. Both horns can stop working, which dealers fix under warranty. Some owners wait months for a service appointment.

14 complaints total

POWER TRAIN

5 complaints

Abrupt deceleration with a "check electrical system" warning is the core complaint. The car drops to 25 mph or less, sometimes to about 10 mph in highway traffic, and some cars stop in a live lane. Dealers diagnose a failed ICCU, often with a blown fuse or a 12V battery that will not charge from the main battery. One failure shows up the morning after a Level 2 charge at 20,013 miles. Owners say the software updates did not prevent it, and some cars sit at dealers for weeks.

5 complaints total

UNKNOWN OR OTHER

5 complaints

The horn goes completely silent in most of these reports, and repairs can stall while dealers wait for parts. A turn-signal stalk can also crack and sag behind the steering wheel during normal use. The one owner who reports it was quoted $1400 for a repair not covered by warranty. A separate report describes the car stopping abruptly while backing out and turning in snow, with parking-sensor warnings showing although nothing was nearby.

5 complaints total

VEHICLE SPEED CONTROL (2 complaints)

VEHICLE SPEED CONTROL

2 complaintsSafety-related

Both complaints allege unintended acceleration at parking speed, and both involve crashes. Drivers say the car surged after their foot left the accelerator. In one case it jumped a curb, hit a parked car and struck a tree. In the other it hit a garage, with property damage over $8,000. One report says the parking collision warning and automatic stopping did not step in. Neither report describes an injury.

2 complaints total2 crashes

STEERING (2 complaints)

STEERING

2 complaints

One complaint is a freeway power loss with warnings for the electrical system, the 12V battery and the ICCU. The car slows to 3 mph and stops in a travel lane at roughly 10k miles. The other describes an off-center steering wheel and a car that wanders over camber changes and rough pavement. A shop found loose rear alignment hardware and heavy outer wear on the left rear tire, which raises blowout and loss-of-control concerns.

2 complaints total

FUEL/PROPULSION SYSTEM (2 complaints)

FUEL/PROPULSION SYSTEM

2 complaints

Both reports describe an ICCU failure that cuts drive power. In one, the unit shorts and blows a fuse after charging, and the car later shuts off on the road. In the other, it pops at 65 mph on a snowy highway. The car drops to 20 mph in traffic and tells the driver to pull over immediately. Both describe a sudden power loss that carries real collision risk at speed.

Frequently Asked Questions

Is the 2024 Hyundai Ioniq 6 reliable?

Yes, it rates good overall and above average among 2024 sedans. It has 33 owner complaints, a low number for its sales. The weak spot is the ICCU, which can fail and cut drive power. Five recalls also apply, so the repair history matters more than the rating alone.

What are the most common problems with the 2024 Hyundai Ioniq 6?

Electrical system trouble leads with 14 complaints, mostly sudden power loss tied to a failed ICCU. Power train follows with 5, describing abrupt slowdowns. Owners also report a dead 12V battery while parked and horns that stop working, which dealers fix under warranty.

Does the 2024 Hyundai Ioniq 6 have ICCU problems?

Yes. Owners report a loud pop, a "check electrical system" warning, then a drop to about 15 to 25 mph before the car shuts down. Failures cluster around 25,000 to 26,000 miles, often in cold weather. Some owners say their car already had the software update.

How many recalls does the 2024 Hyundai Ioniq 6 have?

Federal records list five recalls. Three cover the electrical system, one covers seat belts, and one covers the power train. The 2023 also has five, while the 2025 has three. Ask the seller for proof that every recall repair was completed.

Is the 2024 Hyundai Ioniq 6 better than the 2023 or 2025?

It beats the 2023, which rates worse and has 54 complaints against 33. The 2025 rates about the same, with 30 complaints and 3 recalls. The ICCU power-loss pattern appears across these years, so condition and service records should decide the choice.

Don’t buy a 2024 Hyundai Ioniq 6 without checking its VIN first — hidden accidents, title issues, and open recalls could cost you thousands.
