Should You Buy the 2023 Hyundai Ioniq 6?
Reliability is good, but this is the weakest of the four scored Ioniq 6 years. Against other 2023 sedans it sits close to average. As the first year of the generation, it shows early flaws. The 2024 rates better and has fewer complaints (33 against 54), though both years have 5 recalls. The federal crash-test rating is 5 of 5 stars.
The big issue is the integrated charging control unit (ICCU). Owners see an electrical warning, then a limp mode capped near 22 mph, and some cars shut down in traffic or on the highway. The 12-volt battery often dies too, so the car needs a tow. These failures start around 19,616 to 23,000 miles, can return after a replacement, and parts can take weeks. Smaller groups report false automatic emergency braking, with one injury, and horns that quit, sometimes within 3,000 miles.
Federal recall records list recalls for seat belts, the electrical system (three) and the power train. Ask for proof each was completed, and ask whether the ICCU has been replaced. The 2024 is worth a look.
Compared to the 2024 Hyundai Ioniq 6, which scored 8 points higher.
Pros
- +Acceptable reliability score
- +Low complaint frequency
- +5-star NHTSA crash rating
Cons
- −Moderate recall count
- −ELECTRICAL SYSTEM: Integrated charging control unit (ICCU) failure dominates these reports (29 complaints)
- −POWER TRAIN: Sudden loss of drive power is the main pattern (7 complaints)

Used Buying Checklist
Key things to inspect or verify before purchasing a 2023 Hyundai Ioniq 6.
Scan for stored code P1A9096 and ask for records of any ICCU replacement or software update.
Press the horn and listen for both a high and a low tone.
Have the 12-volt battery tested and confirm the car starts normally after sitting overnight.
Cycle through park, reverse, neutral, and drive several times; confirm the parking brake releases and the car shuts off and locks.
Drive in slow stop-and-go traffic and a parking garage, watching for false emergency braking alerts.
On the highway, lift off and reapply the accelerator, confirming power returns promptly with no warnings.
Open and close the charge door several times, ideally after a cold, wet night.
Inspect the panoramic sunroof glass closely for cracks, chips, or replacement.
2023 Hyundai Ioniq 6 Common Problems by Component
54 owner complaints grouped by vehicle system.
ELECTRICAL SYSTEM
29 complaintsIntegrated charging control unit (ICCU) failure dominates these reports. A "check vehicle power supply" or electrical warning appears, the car drops into a limp mode capped near 22 mph, and some cars then shut down in traffic or on the highway. The 12-volt battery often dies with it, so cars need a tow and a jump. Several failures follow a dealer software update, and failures can recur after an ICCU replacement. Parts can take weeks. Smaller groups report horn failures, sometimes within 3,000 miles, and parking brake faults that leave the car stuck in neutral.
POWER TRAIN
7 complaintsSudden loss of drive power is the main pattern. Many cases trace to ICCU failure: a warning appears, sometimes after a loud pop, and speed drops to about 25 mph before the car quits. Others happen with no warning lights at all. These include a full loss of power and steering on the highway around 18,000 miles that the dealer could not duplicate, and an accelerator that stops responding until the car restarts. A separate complaint describes the car lurching forward while parking. Losing power in traffic or at intersections carries a real crash risk.
UNKNOWN OR OTHER
7 complaintsHorn failure leads this category. The two-tone horn loses its low tone first, then quits completely, and one car blew its horn fuse 4 times in 5,000 miles. Drivers say they cannot warn others during near-collisions. ICCU failure also appears here, leaving a parked car undrivable at 19,616 miles and confirmed by the dealer, with a loaner provided during the warranty repair. A single report describes the panoramic sunroof shattering outward at highway speed with no sign of impact.
FORWARD COLLISION AVOIDANCE (3 complaints)
FORWARD COLLISION AVOIDANCE
3 complaintsFalse automatic emergency braking is the complaint. The system warns of a collision that is not there and brakes hard, in one case from highway speed down to around 25 mph, with an injury reported. It also triggers in slow bridge traffic and in an empty covered parking lot, where the car refused to move until restarted. False proximity warnings show up on the same drive in one report. The main danger is a rear-end collision from a following car.
FUEL/PROPULSION SYSTEM (2 complaints)
FUEL/PROPULSION SYSTEM
2 complaintsThe charge door freezes shut after rain followed by below-freezing temperatures, then opens once the day warms up. No warning appears, and a driver far from home could be left unable to charge. The other complaint here is another ICCU failure: an electrical warning tells the driver to stop, the app shows code P1A9096, and the dealer replaces the ICCU. Only 2 complaints fall in this category, so the pattern is thin.
STRUCTURE (1 complaints)
STRUCTURE
1 complaintSubject: Safety Complaint – Sharp Upper Door Edge Causing Facial Injury (Hyundai IONIQ 6, 2023) Message: To whom it may concern, I would like to submit a safety complaint regarding my 2023 Hyundai IONIQ 6 (VIN: [XXX] ). On October 14, 2024, my wife suffered a facial injury caused by an extremely sharp upper edge of the front door. This occurred in our driveway at [XXX] . The injury happened when the front door stopped at its mid-detent position and the sharp, exposed upper edge made forceful contact with her forehead and the area next to her eye. She avoided a direct eye injury only due to quick reflex. This design presents a serious risk to passengers, especially those of shorter stature. I have photographic documentation showing the sharp door edge and the injury mechanism. Hyundai Motor America was informed, but they dismissed the case and advised us simply to “be more careful.” They offered a $150 virtual compensation card, which I did not use, because accepting it could be interpreted as accepting their proposed settlement. Hyundai insisted on dealer inspection, which is irrelevant because this is not a defect of a single unit — all vehicles of this model have the same door-edge geometry. I believe this is a safety-related design hazard affecting all Hyundai IONIQ 6 vehicles. I respectfully request that NHTSA review this case, as the risk of eye or facial injury is significant. Please let me know if you require additional information or photographs. Sincerely, [XXX] [XXX] Phone [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
ENGINE (1 complaints)
ENGINE
1 complaintWhile driving, "check power system" warning appeared on this 2023 Hyundai Ioniq 6. Moments later an alarm sounded advising to stop driving and turn off engine. I was able to drive to a safe place although the vehicle would not accelerate beyond approximately 15 mph. Car was conveyed by carrier truck to dealer where as of this date it has remained for two weeks as the service department awaits parts. Note: all prior software updates/recalls had been completed before this unfortunate incident occurred.
SEATS (1 complaints)
SEATS
1 complaintThe driver seat is causing back, glute and groin pain. The car has been driven for only 1.7k miles, but the seat cushions already have so much give that one can easily feel the frame under the seat when sitting or pressing down with an open hand. The back of the seat has so much give that it is possible to feel the plastic behind the seat back cushion. I will include photos, but unfortunately it is rather difficult to capture the issue in photos. The issue is constant and ongoing. Aside from causing pain that is requiring medication, the uncomfortable seating is distracting and experiencing numbness in your legs while driving are both clear a safety concern. The dealership, as well as Hyundai USA’s customer service, are refusing to take any action on these concerns. Instead they have given me the run around for 4 months saying I should contact customer service or the dealership, respectively. The dealer has inspected the car, but maintains that there is no issue. I would be happy to get the car assessed by somebody independent if NHTSA as suggestions in that regard. The issue first became apparent after driving the car for daily commutes shortly after taking possession of it.
BACK OVER PREVENTION (1 complaints)
BACK OVER PREVENTION
1 complaintThe contact owns a 2023 Hyundai Ioniq 6. The contact stated that while reversing, the brake lights interfered with the optics of the back-up camera. The inference caused the camera image to be distorted which affected the visibility while reversing. There was no warning light illuminated. The contact stated that the failure persisted. The vehicle was taken to the dealer to be diagnosed; however, the vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 3,518.
EXTERIOR LIGHTING (1 complaints)
EXTERIOR LIGHTING
1 complaintHeadlights do not illuminate the road properly, there are dark spot in front of the car specially on the driver side. Making a turn there is ZERO visibility ( almost went into the median road ) because I do not see anything on the sides. The headlights do not " flood the road " Hyundai say this about the headlight and is very misleading. I drive a lot specially at night I am afraid to drive the car like that. A 2023 52k should not have these issues. BIG safety issues. To have a dealer check the car out I have to wait a month, so I am waiting. Please see the link below here is what Hyundai says about the " state of the art " headlights. Even driving in the city visibility is very bad. [XXX] . Thanks.
