This incident just happened around 9:50pm. I have a 2024 ioniq 6 SEL with 2900 miles. I lost power to my motor while going below 45 mph. The gage that shows acceleration and recharge, zeroed out, showing absolutely nothing. Once I came to a complete stop, I had to restart the car for the accelerator to work. I am on 37% charge. This is not a low charge. There were no warning lights or sounds. I had smart ventilation on as well as lane assist. The steering wheel control became very sticky as the car began to lose power. I am thankful that this was a low speed occurrence and not highway speeds. The fact that I couldnât accelerate means that if something was oncoming, I was in essence a sitting duck. This is the first time the problem has occurred in my vehicle and has not been inspected.

I received the safety recall letter and attempted to make an appointment with Modern Hyundai of Concord, NC. Service appointments were listed online beginning at the end of August and had available time slots, I wanted to check on any further availability so I called. Once I had the service department on the phone I was told that the earliest they would be able to schedule me is in October. I reiterated this was a safety recall and I purchased the vehicle from this dealership and was told that the dealership is a "high volume service center" and nothing could be done until October.

To date, our experience driving the 2024 Hyundai Ioniq 6 has been a total "NIGHTMARE." We've had 2 "TERRIFYING ACCIDENTS" within the first 6 months of leasing this vehicle, Both caused by "Unintended Acceleration Issues," the car "randomly" accelerates, on it's own! 1st ACCIDENT (4/25/2024) - As my wife pulls into our driveway, the car suddenly accelerates (un-commanded) and smashes in the garage, the damage was over $8,000 dollars, (we paid out of pocket) ... Thank God, she was not HURT! State Farm Insurance paid over $20K to repair the car, we paid $500 deductible. It took over 10 weeks to complete all repairs. After we got the car back, my wife was "very apprehensive" to drive for two weeks, finally, able to summon enough courage, she got back behind the wheel and then came the 2nd ACCIDENT( 8/25/24) - While pulling into a Jamba Juice parking spot, the car did it "AGAIN," (unintended acceleration), Jumping the curb, plowing into greenery, shrubs and block wall. Again, 'EXTREMELY" fortunate no one was hurt of "KILLED!" The car was towed to SLO Hyundai Dealership, then back to Kaisen Collision Center, for 2nd time, all within 6 weeks! The repair completion date, is estimated for 9/13/24 with approximate cost at $13K dollars, to date. "REGARDLESS" of all that, we feel blessed to be "WALKING AWAY," from the vehicle, (literally & figuratively)! We are "DONE" ... the car is a total "DEATH TRAP." Immediately following ACCIDENT #2, we called SLO Dealership to report (2nd accident), stating, we are "FINISHED" with the car & "REFUSE" to drive it again! SLO Dealership was apologetic and stated they could "VOID OUT" Lease Agreement, "ONLY" if we paid dealership, roughly $8K dollars (Citing: "Car Depreciation," after "YOUR" Two Accidents - CarFax report). Now, this where the rubber meets the road, we vehemently refrut dealerships allocation, we take total culpability, paying them an extra $8K to return this (heavily documented), "FLAWED" vehicle.

I had my first ICCU recall issue, it was taken care of at Holler Hyundai in Orlando, Florida. I don't even remember seeing a recall email sent out to me, or even a call given about the ongoing recall issues. I found out about the ICCU issues from Reddit of all places, but post after post of people detailing their issues. My concern is that there's numerous post, about EV battery failure while driving or getting ready to take a trip. Imagine getting locked out of your car in freezing temperatures? Due to it being an EV it's a lot more difficult to start or get in, and I don't always carry my physical key. I only received on key, so imagine if I lose that one. You can't use the app or key fob to get in, cause everything works off the 12v battery which is in operable at that point. Hyundai is not addressing this issue with its customers, or even potential customers which is disheartening. It only takes one fatal mistake before something horrible happens. At this point I don't feel safe driving it, definitely won't plan any trip more than 20 miles. Have you guys heard any news on the ICCU issue, what's causing it mechanical, software or otherwise?

Today, I had a scary situation on my 2024 Hyundai Ioniq 6 limited. While backing out of a parking space, I put my foot on the brake to place the car in drive and the car kept rolling back no matter what I did and almost crash into the car park across. I was able to finally stop the car by placing it into park repeatedly. I was inches from striking the car across when it finally came to a stop. I then attempted to place it in drive again and no dice. I had to turn the car off and back on to get it to respond and place it back to drive. Anyone else experience this helpless feeling? Quite scary. This vehicle has had the various ICCU updates performed.

The power system failure warning came on as I was driving up on an intersection. WhenI released the accelerator because I was in i-pedal mode (one pedal driving), the cars braking system did not activate. Consequently, I ran the red light. The car power was reduced, and I was able to pull into the parking lot of a strip mall as a police vehicle pulled behind me. After explaining our situation and receiving my traffic ticket, the officer asked me to move the car out of the driveway, but I was unable to shift the car into drive given the power warnings that were flashing on the display. The officer asked if I needed a tow and I let him know I would use the brandâs Roadside Assistance for my vehicle. I turned the car off and the officer left. I waited about 10 minutes and I tried turning on the car again and was able to shift into drive and get out of the driveway and into a parking space. However, the car operated in low power mode and could only travel about 3 miles an hour. The tow truck driver had to jump the 12 V battery which was completely depleted in order to turn on the vehicle to move it. At Hyundai Service center, the car turned off abruptly as he was trying to move it into a parking spot. Despite supposedly having been addressed in a recall, the failure of the vehicleâs power system due to the ICCU put me in my family at risk while actively driving on a road with traffic.

Both the high and low tone horns on the car failed with 7500 miles on the vehicle. This has caused the inability to warn other drivers of lane encroachment or alerts. The part is being replaced under warranty currently waiting on the part to arrive. Estimated repair date 11/22/24 As a member of multiple Hyundai Ioniq groups this seems to be a common failure across more Hyundai models then just the Ioniq.

Driving on middle lane of fast freeway with kids in the car. The car began beeping lights of an electric malfunction, a 12v battery malfunction, an ICCU malfunction and then started to slow down all the way to 3 miles per hour and then it stopped in the middle of the freeway. A car behind us almost crashed into us and would have killed us. I feel very u safe and Hyundai will not do anything about it. Itâs a one year old lease of a 2024 EV with barely 10k miles on it. They are not fixing in time and it also shows a recall that they didnât accommodate or were able to schedule.

INCIDENT ONE: On 3/20/25 about 5 minutes after starting Climate Control on my Ioniq 6, I cleaned snow off the car and started it. As I started backing out, there was a loud warning sound and red indicators around the aerial image of the car on the dashboard. I double checked my surroundings and found no obstructions, so I continued to back out. As I began to turn the car into the direction I needed to head down the street, the car abruptly stopped. I had to put the car back into Drive and pulled forward. I checked again for snow on the bumpers and found none, so I backed out again, this time successfully. When I reached the intersection and tried to turn, the car again abruptly stopped and automatically sounded the horn. The car stopped in the lane of oncoming traffic, but there were no cars approaching. Again I had to put the car back into Drive. I pulled over and took a cloth and glass cleaner to wipe down the cameras. After doing this, I was able to continue on my commute without seeing red lines around the image of the car and without being abruptly stopped when turning. The dealer was unable to reproduce the problem, which they attempted to do under different weather conditions from those on the morning of March 20th. INCIDENT TWO: On 4/7/25, driving on a four-lane highway, a car pulled in front of me without signaling. I tried to alert them to my presence by sounding the horn. The space in the center of the steering wheel (with the horn icon on it) produced no sound when pressed. This was alarming. Fortunately I was able to slow down, and I was not hit by a car from behind. Later. I tried the horn again several times with no sound produced. The dealer repaired the horns.

As I was driving home from work, a loud POP went off under my car, and sirens began to go off. I was given a critical error, and told to immediately contact a dealership. My car began to slow, and would only go 25 mph. Luckily for me I was within a few miles of a dealership, but if I wasn't so fortunate this would have been a much larger issue. The ICCU has failed, despite already getting Hyundai's recall for this issue performed. I am now without my car for an unknown quantity of time.
