Hyundai has installed faulty 12v batteries in the Ioniq 5 series cars. The OEM battery fails, resulting in an emergency stop or failure to start. Hyundai refuses to acknowledge the faulty batteries, yet the resolution found by numerous consumes to resolve the issue has been to purchase and install the correct 12v battery. Despite going to the dealership to seek a remedy, they refused to replace the faulty battery. They asked for the dead car to be towed into them, but Hyundai roadside assistance is unable to have towed a dead EV. 5 times the car died in the first 6 months of ownership. Hundreds if not thousands of US owners online have reported the faulty 12v issue to Hyundai, received no working repairs, and ultimately replaced their batteries at their cost.

12V battery dead. It is only 5 months and the start battery is dead. I needed jump start and the problem reoccurring. I hear this is a common problem for all HI 5 models. So why it is not part of recall? Dealership is asking money for replacement. Repeated reoccurring dead battery issue.

Received orange warning -??Power limited-??. A minute or so later received RED warning -??Stop vehicle and check power supply-??. Less than a minute later the car stopped and turned off completely, even the HAZARD lights would not flash. Tow truck was unable to tow because the car could not be taken out of park, wheels locked. Also, as soon as the warnings started the power steering failed and the car was very difficult to maneuver. The combination of difficult maneuvering followed by unable to move could be VERY dangerous in the wrong situation.

I received this car new on 9/2/2024. I was driving at the freeway speed of traffic on 9/5/2024 when there was a sudden alarm and warning lights flashing on the dashboard with a message that said -??Stop vehicle and check brake system.-?? At this same time, the brakes stopped functioning normally, and I had to use extreme pressure with my foot pressing down on the brake pedal all the way to the floor to have the car slow down even marginally. All of this happened with traffic in front, behind, and on both sides of me going 65 mph! I was very luckily able to maneuver to the right lane and slowly decrease speed without getting rear-ended and without slamming into a car in front of me while going at high speed unable to stop. While waiting for a tow, I left the car on, as I slowly edged forward to a safer stopping location. The flashing red ring around the message to -??stop vehicle and check brake system-?? remained, and then just after moving forward, another message with an amber circle around it said -??Check ABS system.-?? This latter message stayed on for only a short time, then was replaced by the initial message. I had the car towed to the dealership, and their assessment was that there was a failure of the IEP module that communicates between aspects of the braking system. The final service report is attached, confirming the need for replacement of the IEP assembly. I was very lucky to come away from this event with nothing more than a very frightening experience. I hope that this report will initiate a recall to prevent a similar situation happening to someone else, and hopefully avoid tragedy involving serious injury or death.

I was driving on the highway and a message appeared that said -??check electrical system-??. The power in the car then completely bottomed out and I could not go above 25 mph.

I am writing to report serious issues with my 2024 Hyundai Ioniq 5 SEL, purchased on May 24, 2024, with approximately 3,000 miles driven. These problems have raised significant concerns about the vehicle's reliability and safety. The first incident occurred on July 22, 2024. I attempted to start the car in my driveway, and while the engine turned on, the vehicle suddenly lost power, and all electrical components became non-functional. There were no error messages, and the display showed all systems as normal. It seemed to function normally after turning the vehicle off and on again, but this unexpected power loss was alarming. The problems continued today, August 3, 2024. At around 8 AM, when I tried to start the car again, the system flickered twice and then shut off entirely. I contacted roadside assistance, and the car required a battery charge for about six hours before it could start again. This evening, while driving at approximately 15 miles per hour in my subdivision, the vehicle suddenly lost power after only a few minutes. This abrupt power loss posed a significant safety risk, and I was fortunate to avoid an accident. I contacted the dealer who sold me the vehicle, but they informed me that they could do nothing remotely and advised me to have the car towed to their location. It is extremely concerning and frustrating to encounter such severe issues with a new vehicle. Given the repeated and unpredictable nature of these problems, I urge Hyundai to take immediate action to investigate and resolve these issues. I am also concerned that other owners may be experiencing similar problems, indicating a potential widespread issue with this model. I am seeking urgent assistance to address these issues and ensure the safety and reliability of my vehicle. Thank you for your prompt attention to this matter.

Backing vehicle out of driveway and went to engage brakes and they did not engage. began rolling backwards down street with steep grade. Kept stepping on brakes with no response. Had to turn into a parked vehicle to keep from rolling down steep grade and potentially off a substantial cliff. Happened today and dealership said that it may be because the "battery for the brake" had not received a charge from the main battery. Very dangerous and never disclosed. If I had not taken evasive action I could have easily been killed. Car is being dropped off at collision center today but is available for inspection. There were no warnings or other symptoms.

Auto lost all power. No instruments visible. Propulsion system would not charge. Thankfully vehicle at a stop when occurred. Unable to drive. Car as dead as a home in a power outage. Everything dark. Nothing electrical worked. Had to use emergency manual key to enter vehicle. Tow truck driver said this was the 4th Hyundai Ioniq 5 he towed that week. All dead. Car at dealer awaiting diagnostics, which because of backlog, could take 3 or 4 weeks.

My vehicle was 4 weeks old. On Friday 6/28/24, my vehicle displayed the following message on the dashboard, "Check Brake System". It disappeared later, and reappeared on the next day. I checked Hyundai's app, Bluelink. There was a alert on Bluelink, "Attention Needed". I opened the alert and it said that there was a Diagnostic Trouble Code, DTC C123501, that originated on 6/30/24. I took the vehicle to the dealership, Hyundai of North Miami, on the next business day, [XXX]. That morning, [XXX], as I started the vehicle, as I stepped on the brake to start the vehicle, the brake was considered "softer" than it was prior and I could feel the brake pedal go nearly all the way down to the base of the vehicle floor. On [XXX] they informed me that the ICCU needed to be replaced. They said that they hoped to have the ability to order the part on 7/5/24, as the computer system needed to do so was not working, and the part could potentially arrive in approximately 1 week.

1. Uncertain which part failed. 2. safety was put at risk due to car not able to accelerate. Car would not go over 20 miles an hour on the interstate access road where traffic was going by at 50 -?"60 mph - four-way flashers were on and had to pull off at the first available turn but it was scary 3. Contacted local Hyundai; they are investigating a possible loaner, but haven-??t said what they will do. 4. No inspections yet. 5. No warning or unusual events prior to lack of power/lack of acceleration. 6. Internet search showed that this problem has occurred to others.
