2024 HYUNDAI IONIQ 5 Complaints

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.

1. Brake Failure: recently when my brakes stopped responding while driving.The pedal went all the way to the floor, and I barely managed to stop the car. 2. Knocking sound when braking: I started to notice a clunking/knocking sound that would occur when braking and just about coming to a stop.

When driving in i-Pedal, which is a "one pedal driving option", sometimes after pausing the car rolls backs several inches. This appears to be a defect with the powetrain, regenerative braking engine, or otherwise. Hyundai's dealership has been advised of this issue; they have escalated this internally. A car in drive forward should never due to electrical or software reasons be told to move backwards -- which is what is happening here.

Went to charge at AC charger and found that it would not charge. Tried another charger and same thing occurred. Car would say 0.3kW and than stop charging. Dealer said ICCU issue.

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.

Car will randomly start giving warning messages (while driving or parked). Messages include pull over and check brake system, lane departure system failure, check battery, the speedometer will read 0 while driving, among multiple others. Dealership has ' fixed' multiple times, replacing fuses, bumper, sensors, but the problem keeps happening

When on a highway with lane-keeping assist engaged, the car sometimes steers into the left-hand lane. It seems to happen most often when the road bends to the right. The car straddles the lane divider into the fast lane to the left. This occurs in otherwise perfect conditions: sunny, dry days on roads with clear white stripes demarking the lanes. I must fight with it to get it back in the proper lane. This is very dangerous. I'm convinced it will cause a high-speed crash. Another driver I spoke with said she had seen the same problem and wouldn't use the lane guidance because of it. I'm extremely cautious when I use it now. The problem has happened multiple times.

Overnight, the windshield spontaneously developed a huge crack going from the A-pillar to halfway across the windshield. The car was parked at the time.

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.
