29 complaints total

POWER TRAIN

7 complaints

Subject: 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)

While 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 complaint

The 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.

The 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.

Headlights 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.

How We Calculate Reliability Scores

Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.

Key Ranking Factors

1

Complaint Severity

NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

Recall Impact

Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.

4

Issue Diversity

Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.

Scores are grouped into four tiers:

  • 80–100: Excellent— Top-tier reliability, minimal issues
  • 60–79: Good— Reliable with some minor concerns
  • 40–59: Mixed— Notable issues, research before buying
  • 0–39: Risky— Significant problems, proceed with caution

Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.

Get notified when new recalls or reliability data is added for the Hyundai Ioniq 6.
