The horns quit working. I'm on two weeks now waiting for the dealer to get the parts in to fix it. According to what I saw online, this is an ongoing issue.

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.

ELECTRICAL SYSTEM
I own a 2024 Hyundai Ioniq 6 that experienced a complete 12V battery failure at under 500 miles of use, despite showing normal voltage levels (12.5V off, 13.25V while attempting a jump). The vehicle was undrivable and could not start, even though the main battery (MV) was at 70% charge. There were no prior warning lamps or messages before the failure. The vehicle had to be towed and left inoperable for nearly 30 days. According to the servicing Hyundai dealership, the root cause was determined to be a failure caused by Hyundai’s own connected app, Bluelink — which the dealer explicitly said is the root cause for my batteries failure. Hyundai Motor America, however, has refused to acknowledge this diagnosis, and despite repeated inquiries over a 60-day period, has not provided any explanation or confirmation of the cause. They continue to point back to the dealer while providing no warranty-related answers, no documentation of testing done, and no safety assurance that the failure won’t recur. The issue puts safety at risk, as the 12V battery’s failure renders the entire EV completely disabled — without warning. This creates potential for owners to be stranded, especially if the issue occurs in unsafe or remote locations. In my case, roadside assistance failed to be able to pick up the vehicle twice, resulting in a 12-hour ordeal. Hyundai has made no effort to formally investigate the potential connection to Bluelink and appears to be suppressing acknowledgment of the defect trying to offer me a one month payment instead of acknowledging or confirming this is a possible issue that can happen again in the future contingent on me saying my concerns are resolved; they're not. The resolution involved a tech having to use a third party tech line & no data within the invoice. I believe this is a broader safety issue affecting other Hyundai EVs using the Bluelink system and that NHTSA should investigate whether this poses systemic risk across affected vehicles.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
Since implementation of the recall (software update on ICCU) in January, the 12v battery has gone dead 3 times (every ~3 weeks) while the vehicle was parked overnight. It hadn't had this problem in the 6 months prior to the software update, and the dealer shop is unable to diagnose a problem. They say they are unable to reverse the software "fix" which seems to have caused the problem, and refuse to replace the ICCU.

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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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?

Vehicle horn suddenly stopped working. Couldn't alert another driver who didn't see my vehicle and was cutting me off. Took the vehicle to the dealership who mentioned it was a safety issue and repaired the horn at no cost. Read several posts online where other Ioniq 6 drivers have reported horn malfunctions. No warning lights or messages appeared before or during the incident.

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. It’s 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 didn’t accommodate or were able to schedule.

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.

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 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.

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 couldn’t 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.

Within one month of purchase I noticed a bubble in the paint. The bubble is now cracking and affecting the gunmetal blue paint. I’m concerned this paint problem will lead to chipping and peeling in the paint.
