2022 Hyundai Ioniq 5

1) This is the second occurrence of this issue within the past 12 months. While driving, my EV displayed various blinking lights and a “Check EV Connection” message, followed by a “12v Battery Critical” warning. The entire system began shutting down in the middle of the road. I managed to pull over before the car completely shut off. 2) This malfunction posed a significant safety risk to me and others. The rapid deceleration and uncertainty of an imminent shutdown almost caused an accident, either from other vehicles crashing into me or from my inability to stop in time, potentially hitting another car. I have faced this life-threatening situation twice within a year due to the same issue. 3) The problem was confirmed by my dealership less than a year ago, and my car is currently being towed back to the dealership for re-inspection of the same issue. 4) The vehicle and its components have not been inspected by the manufacturer, police, insurance representatives, or other parties for the current situation. However, the manufacturer issued a recall for this problem last year AFTER my initial report, incident, and repair. They claimed to have fixed the faulty issue or replaced the necessary parts, when my vehicle was repaired less than 12 months ago. Despite this, I am experiencing the same critical problem again. 5) During the incident, my entire panel started blinking with a “Check EV Connection” message, followed by a red warning sign indicating a 12v Battery Critical Failure warning. The system then went black, and the panel continued to blink white and black consistently while parked. The car cannot be started or moved.

Turning into my driveway one evening, the car displayed the "Check Electric Vehicle System" alert on dash. The following morning while backing out of the driveway to wait for a tow, the alert changed to "Stop vehicle and check power supply". Got car towed to dealer, and after diagnosing, confirmed that ICCU failed. Car has been at the dealer for almost 2 weeks at this point, and the part is still back-ordered with no ETA, according to the service advisor I have been working with.

I had the most recent recall (code 702 I believe) done on January 13th. I believe the recall was an NHTSA required recall and after the software update that was part of the recall my car will no longer charge. It has been with the dealer since January 15th with no resolution in sight. The software update was I believe the 4th such update intended to prevent a part called an ICCU from failing. It took 4 business days but the dealer Hyundai of Roseville confirmed the ICCU needs to be replaced and they don’t have an ETA on when the part will be shipped. Online I have seen reports of the same thing happening to others and the ICCU repair process taking 1-2 months.

Electrical system failure. Available for inspection upon request. While driving, warning appeared on dashboard. Warning said, "Stop Vehicle and Check Power Supply" The safety of vehicle occupants and others on the road was put at risk. I lost control of the vehicle in the middle of traffic due to the loss of electrical power. The problem has been confirmed by San Leandro Hyundai as part of the Safety Recall for the Integrated Charging Control Unit, Recall number 272. NHTSA Recall number 24V-868. The recall repair was completed but the ICCU was not replaced and is still defective. A few minutes prior to the eletrical failure a warning message appeared on the dashboard. The warning message said, "Stop Vehicle and Check Power Supply". First appeared on Saturday January 11th at 4PM (PT).

The vehicle has no power whatsoever. Upon approaching the vehicle, it did not unlock. I used the physical key to open the drivers door. I then tried starting the vehicle only to have the gauge and center display flashing on and off with a red warning That the 12v was dead, to pull over and top immediately then the displays turned off. There are no lights or power to the vehicle no whatsoever. It cannot turn on any of the interior lights or even power door locks. This means only the front doors can be opened or locked and the vehicle will obviously not move. The 12v battery system has been a continuing issue with the vehicle. It has been repaired and the subject of several recalls during my short ownership and is still a problem. Due to a blizzard, I have been unable to have the vehicle taken to the dealership and have been without transportation for 3 days already with no clear resolution from Hyundai.

On [XXX], I was driving my 2022 Hyundai Ioniq 5 SEL when all of a sudden the car started beeping and displaying a 12V battery voltage low. Stop safely message. I was traveling on [XXX] in the Las Vegas area and the car all of a sudden came shut off seconds later. This presented a very dangerous situation with other vehicles traveling at 65+ mph and the vehicle shutting off. I was able to use a portable power jump starting pack to at least get the car restarted and pulled off the side of the highway. Even after jump starting the vehicle, it would only stay running for a minute before shutting off again. The is the second time in 2 months that my car has lost power. The dealer, ABC Hyundai in Las Vegas did a ICCU recall and said that would solve the problems. The problem has not been resolved and I do not feel this is a safe vehicle to drive.

Today when I was driving down a canyon going 40 mph, the car started coasting and the accelerator was unresponsive. I couldn't keep the car from decreasing speed and regen braking wasn't working either. I don't know whether it's related, but this happened within seconds of me turning off daylight savings time in the menu. I coasted to a safe place to pull over (the brakes worked fine), but I could not get the accelerator to work after switching from drive to park to drive again. After turning the car off and then back on, the accelerator again worked like normal. After continuing driving, I turned daylight savings time on and off a few times, but nothing adverse happened.

On Saturday, [XXX], at approximately [XXX], I drove my 2022 Hyundai Ioniq 5 north on [XXX] . The car was operating normally. I stopped at the red light at the corner of [XXX] and noticed a large red circle with a "Check electrical system" warning on the driver's display screen. When the traffic light turned green, I pressed the accelerator pedal, and the car did not move. I looked at the "Park, Neutral, Reverse, Drive" shifter. The "P" was lit up, indicating the car was in "Park." I attempted to switch to "Drive," and the status indicator remained in "P." I then pushed the "EV START STOP" switch to see if I could cycle the vehicle off and then back on to clear the problem. The switch had no effect. [XXX] is a busy four-lane, undivided street near the University of Colorado at Boulder campus. I selected the hazard flashers and called 911 to alert the Boulder Police Department that I was in a car that was immobilized in the middle of the right-hand northbound lane. Cars had to swerve to avoid me. The Police Department dispatched a vehicle that arrived 10 minutes later, pulled up behind me, and put its flashing lights on to alert traffic. While waiting for the tow truck, I received another alert on the driver's display that informed me that the 12-volt battery was nearly completely discharged, and I had 10 minutes of power left. The warning counted the remaining minutes to 0, and the displays shut down. From the first warning message to the shutdown, I could not turn the car system off or shift the car out of the park. The tow company had to put dollies under the rear wheels of the Ioniq 5 and lift the front end off the ground to tow the vehicle, as all four wheels were locked. The car was towed to Crossroads Hyundai in Loveland, Colorado. It had just been serviced to address all the recall issues, including the ICCU software update. The car has approximately 16,000 miles on it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A warning to check electrical system was displayed. The battery did not have sufficient charge to drive it to a dealer so I tried to charge and the car would not charge past 60%. I was able to drive the car to the dealer where they diagnosed a failed EV battery. Prior to the failure the car would use battery percentage much faster than it should have. For example, a fifteen mile drive would deplete the battery 25 miles. The dealer still has the car waiting to replace the battery.
