What 2024 Hyundai Ioniq 6 owners say
Electrical system all 21 →
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 brand's 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. …
I experienced a safety critical failure in my 2024 Hyundai Ionic 6. While attempting to start the vehicle, the car displayed a red 12 Volt battery warning light, a battery discharge warning, and then refused to enter ready mode. The vehicle would only shift into neutral and was completely undrivable. After sitting for many hours, the vehicle started again, which is consistent with an intermittent ICCU/DC-DC converter dropout. This type of failure is known to cause loss of power and has been documented in NHTSA investigation PE23-011 for other Hyundai EV's. The dealership states they cannot replicate the issue and refuses further diagnostics. Hyundai corporate is deferring entirely to the dealership and will not authorize a loaner or confirm reimbursement, leaving me without transportation. …
Speed control & acceleration
I was parking my car a Hyundai Ioniq 6, in an easy parking space when I briefly removed my foot, which was lightly depressed on the gas pedal to hit the brake pedal, the car suddenly accelerated jumped the curb hit another car and hit a tree. The airbag did not deploy I am uninjured. The other car was parked, but was damaged. My car was damaged. It all happened in about two or three seconds and my foot was no longer on the gas pedal. Moreover, the automated systems for parking collision warning, and for automatic stopping did not work. This is what came up when I googled it. Reports suggest some Hyundai Ioniq models, including potential Ioniq 6 instances, may exhibit unexpected, brief acceleration following a software update meant to address a separate braking recall. …
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. …
Transmission & drivetrain
When driving recently, the car suddenly began showing a warning message "check electrical system" and would not go beyond 25mph. I was on the way home but still far, and had to turn on my hazard lights to alert other drivers. Eventually the car escalated the warning to "pull the vehicle over" and implied that the main battery was having an issue. I had to have th car towed to a dealer (closest is 10 miles) who eventually diagnosed the issue as a blown ICCU. My understanding is this is a critical component to the charging infrastructure and must be fully operational for the car to safely drive. Hyundai repaired the part and I had the car back in a few days, but I could get no assurances on what happened or whether or not it would occur again. The car has 14,000 Miles in the Washington DC area. It seems incredibly unsafe that this component could blow at any time. …
The morning after a successful level 2 charge (from 35% to 80%), the ICCU fuse blew, resulting in no power to the car. I had to have it towed to have it fixed (both the fuse and ICCU were replaced under warranty). The car had 20,013 miles when the fuse blew and I had both safety recalls (software updates) addressed when they came out. I thought the updates were to prevent this from happening. Fortunately I was in my garage and not on the road; however, just the evening before, I was on I-95 for over an hour and glad it did not occur then. So now I'm fearful that it could happen again when far from home.
