Common Hyundai Ioniq 6 problems

The 2023 Hyundai Ioniq 6 has been praised for its futuristic design and impressive performance, but some owners have reported a number of issues that could potentially affect its reliability. Here are some of the most common problems based on complaints from owners of this car:

  • Overheating while level 2 charging: The Ioniq 6 is capable of charging at up to 40 amps, but some owners have reported that the car can overheat while charging at this level. This can be a serious problem, as overheating can damage the battery and reduce its lifespan. It can also lead to longer charging times and increased wear and tear on the charging system.
  • Check Forward Safety System: Some owners have reported issues with the car's forward safety system, which is designed to help prevent accidents by alerting the driver to potential hazards. This can include problems with the car's sensors or cameras, which can cause the system to malfunction or fail to detect obstacles in the road.
  • Check Electric Vehicle System: Some owners have reported issues with the car's electric vehicle system, which can include problems with the battery, charging system, or motor. These issues can lead to reduced range, decreased performance, or even complete failure of the electric drive system.
  • FOB battery dead: Some owners have reported issues with the car's key fob, including problems with the battery. This can be a significant problem, as the key fob is used to lock and unlock the car, as well as to start the engine. If the battery dies, the owner may not be able to access the car or start the engine.
  • Drive Motor Cooling System: Some owners have reported issues with the car's drive motor cooling system, which is responsible for keeping the electric motor at a safe temperature. This can include problems with the coolant, cooling fans, or other components of the cooling system. If the cooling system fails, it can lead to reduced range, decreased performance, or even complete failure of the electric drive system.
  • Brake Lights issue: Some owners have reported issues with the car's brake lights, including problems with the bulbs or wiring. This can be a significant safety issue, as brake lights are essential for alerting other drivers to the car's presence and intentions. If the brake lights fail, the driver may not be able to signal their intentions to other drivers, increasing the risk of accidents.
  • Tailgate rattles: Some owners have reported issues with the car's tailgate, including rattles and other noises. This can be a significant annoyance, as it can make the car feel less refined and more prone to mechanical issues. It can also lead to decreased resale value, as buyers may be less interested in a car that has noticeable rattles or other noises.
  • Slight flutter during acceleration: Some owners have reported a slight flutter or vibration during acceleration. This can be a significant problem, as it can make the car feel less refined and more prone to mechanical issues. It can also lead to decreased performance, as the car may not accelerate as smoothly or quickly as it should.

It's important to note that these issues are based on complaints from owners of the 2023 Hyundai Ioniq 6, and not all owners will experience these problems. However, potential buyers should be aware of these issues and consider them when making their purchasing decision. It's also worth noting that the Ioniq 6 is still a relatively new car, and some of these issues may be addressed through recalls or software updates.

  • Date Of Incident: 2023-10-16
  • Date Complaint: 2024-03-22
  • VIN: KMHM34AC8PA
  • Components: SEATS
  • Summary: 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.

  • Date Of Incident: 2024-02-12
  • Date Complaint: 2024-02-20
  • Number Of Injuries: 1
  • VIN: KMHM54AC1PA
  • Components: FORWARD COLLISION AVOIDANCE
  • Summary: On the afternoon of February 12, 2024 (5:12pm), I was driving northbound on I-71 at highway speed, approximately 75mph. My Hyundai Ioniq 6 alerted me of a (non-existent) impending front-end collision, and within 1 second of the alert starting, the automatic emergency braking system activated. This resulted in the violent (and unexpected) braking of my car to around 25mph. There was no clear reason for the collision detection alert or the automatic emergency brake. The light was good and there was no significant weather. There were no vehicles immediately in front or behind me. (Nearest car in front was over a quarter mile away.) The force of the braking was sufficiently strong that I am still sore in my shoulder and back a week later. I am fortunate that there wasn't a car close behind me, as I likely would have been rear-ended due to the unexpected and abrupt nature of the braking. The vehicle was taken in for service (invoice attached) and "calibrated". Within 10 miles of getting back on the highway, warnings (but no braking) triggered again. (photo attached of one of the warnings). The vehicle is currently back at dealer service.

  • Date Of Incident: 2024-02-19
  • Date Complaint: 2024-02-20
  • VIN: KMHM54AA7PA
  • Components: POWER TRAIN,VEHICLE SPEED CONTROL
  • Summary: While driving in the highway I took my foot off the accelerator and despite one pedal driving being on the car did not brake. I then tapped the brake. When I then pushed the accelerator to keep up with traffic, nothing happened. I checked the screen for warning lights. The car had none. The accelerator pedal was non responsive causing a huge safety issue for me and others on the road as the car was now just cruising as I was approaching a hill..I had to turn on my hazards and get over into the shoulder of the highway along the bridge at night. I stopped the car. There were still no warning lights on. I turned the car off and back on and the problem was no longer present.

  • Date Of Incident: 2023-11-14
  • Date Complaint: 2023-12-28
  • VIN: KMHM34AC8PA
  • Components: BACK OVER PREVENTION
  • Summary: 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.
Hyundai Ioniq 6 2023
  • Date Of Incident: 2023-12-21
  • Date Complaint: 2023-12-24
  • VIN: KMHM54AC7PA
  • Components: FORWARD COLLISION AVOIDANCE
  • Summary: My Ioniq 6 Limited AWD experienced a phantom braking event in a covered parking lot with no cars or pedestrians anywhere near the front of my car. The car just stopped suddenly with a warning message "Emergency Braking", and it wouldn't allow me to proceed until I turned off the car and then turned it back on. Fortunately, there wasn't a car close behind me at the time, but it could have triggered a rear end collision. Prior to this phantom braking incident, but on the same short drive, I noticed that the car incorrectly showed a red line indicating that the driver's side of my car was extremely close to some object, even though visual inspection confirmed that there was nothing there.

  • Date Of Incident: 2023-09-26
  • Date Complaint: 2023-12-19
  • VIN: KMHM34AA0PA
  • Components: EXTERIOR LIGHTING
  • Summary: 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.

  • Date Of Incident: 2023-11-18
  • Date Complaint: 2023-11-18
  • VIN: KMHM34AA7PA
  • Components: VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM
  • Summary: My Ioniq6 slowed down to 20 mph for the second time tonight. No matter how hard I pressed on the accelerator the car would not speed up past 20 mph. A message on the dashboard said “Limit: 20 mph”. Eventually the car picked up speed then said “Limit: 43 mph”. (The speed limit on University Blvd at this point was 35 mph). I did not test that, as I was almost home. This happened around 7pm on Saturday, Nov 18, 2023. My wife was in the car with me and asked why I was driving so slowly. The first time this happened, a couple weeks ago, I don’t recall seeing a message on the dashboard. I fiddled with some of the controls on the steering wheel and it sped up. So I thought I had fixed it.
Hyundai Ioniq 6 2023
  • Date Of Incident: 2023-07-05
  • Date Complaint: 2023-07-19
  • VIN: KMHM24AA3PA
  • Components: ELECTRICAL SYSTEM
  • Summary: I have a 2023 Ioniq 5 that was purchased in June, 2023 and an 2023 Ioniq 6 that was purchased in April, 2023. I had a new Chargepoint Home Flex charger installed in April when I purchased my Ioniq 6 and set the charging current to 40 amps. The charger was hardwired directly to my service panel with the appropriate 6 gauge wire and 60 amp breaker. My Ioniq 6 reliably charged at 40 amps until early July when it started dropping the charge rate to 23 amps about 40 minutes into my charging session when using the level 2 charger at home. My Ioniq 5 only charged at 40 amps for the first week of ownership before starting to drop the charge rate to 23 amps. When this behavior started I plugged an OBD2 scanner in and was able to monitor the AC Charging Inlet temperature and noticed that the charge drop happened when the temperature reached 240F. This causes an issue when planning my charge times because they can essentially double, meaning that my vehicles are not ready for a trip by the estimated time. I am also concerned that having electronics that overheat on an EV may be a potential fire hazard in the future. One of the key reasons for purchasing these vehicles was the advertised charge times. I have appointments with the dealership to have both of these vehicles diagnosed.

  • Date Of Incident: 2023-06-17
  • Date Complaint: 2023-07-08
  • VIN: KMHM24AB8PA
  • Components: ELECTRICAL SYSTEM
  • Summary: The Ioniq 6 is supposed to be able to charge at 48 amps. I bought a new Ioniq 6 in early June 2023. June 12 I had the level 2 Juice Box 48 amp charger installed. At least twice (I think three times), it would stop charging after about twenty minutes — the charge port appears to be overheating in certain situations. Please have Hyundai either fix the port (or other hardware) and/or software. They may not advertise 48 amp charging when so many users are having overheating problems. They need to own this and be accountable. Precisely this happened on the Ioniq 6 to me: https://youtu.be/uXi33MtrJAU

    Congratulations on your recent purchase of the Limited RWD! It's great to hear that you were able to find a fantastic deal on a 4 month old used car. It sounds like you have a lot of experience with EVs, having owned two others in the past. Your description of the Ioniq 6 Limited is very impressive, especially the beautiful interior and luxury functions. The two-tone ambient lighting sounds amazing! While the exterior design may be polarizing, it's great that you personally enjoy it. Thank you for sharing your thoughts and experiences with us!

    5 days in and I'm blown away with this car! I love its looks and performance. The ride is quiet and smooth, yet it has the power of a beast underneath. The technology is fantastic too. I replaced my Genesis G80 gas car with this, and it's a bargain for what I'm getting. I loved my G80, but Hyundai has reached a new height with this vehicle. If you're looking for an electric sedan, don't hesitate to test drive one!

  3. Shaun Feest 2024-06-18

    Your product has comfortable and sleek lines. However, my concern is that it does not update as it is hardware designed and not software.

  4. Grant Schumm 2024-06-18

    Vehicle year: 2023

    The Ioniq 6 is a fantastic electric car that offers power, beauty, and a luxurious feel. It's definitely a great find that you won't regret!

  5. Lorenza Pfannerstill 2024-03-19

    Vehicle year: 2023

    I recently purchased my first all-electric car and I must say, I am thoroughly impressed! The legroom in the front is perfect for me, even better than any other affordable car on the market. My daughter-in-law, who is much shorter than me, also finds the front seat very comfortable. The backseat also has plenty of legroom, although the headroom is not as great due to the slope of the roof. However, this is not a concern for me as I don't plan on sitting in the back. The trunk is not very big, but for me, the front legroom is the most important feature. I was considering the Hybrid SEL, but I ended up purchasing the Ioniq 6 SE because of the great range and the amazing deals that Hyundai offered me. I am confident that the car will pay for itself in just a few years. I have only had the car for a week, but I am already very impressed with how it rides and drives. The car is very quiet and I have been driving it in Eco mode with no issues. I prefer the Auto re-gen over the 1-pedal driving, especially on the highway. If I were driving around town only, I would probably use the 1-pedal driving. Overall, I am very happy with my purchase of the SE and it seems like others are too, as there are no new ones available within 300 miles of where I live. Hyundai has really hit the mark with this car!
