ELECTRICAL SYSTEM, POWER TRAIN
We've owned the car since new, just over one year. The car was performing well one day and my wife went to her evening work. When she returned to her car around 6pm, the car wouldn't respond to the key fob and the door wouldn't open. She was able to open it with a key, but the car wouldn't start. It's a fully electric car and NOTHING lit up or made a sound. The traction battery had ample charge, but she called Hyundai and the car needed a "jump" from a repair vehicle that was called out, much like an ICE car needs the occasional jump...we assumed an interior light was left on, but the car's app didn't inform either of us of any issue prior to this...the same exact scenario repeated itself about one week later and we had the car jumped again and brought to our dealer, Burns Hyundai in Marlton, NJ. They determined that "nothing was wrong" which made no sense to me. My wife picked up the car and approximately one week later, the exact same thing happened again. This time we dropped the car off at the dealer where it's been for nearly one month. With their customer service lacking and information not forthcoming, I had to go to the dealer myself to get some answers. It seems the computer was telling then some codes were coming through about the battery, but nothing more. It didn't need replacing and they couldn't replicate the problem over a period of weeks...There are MANY online reports of this car having 12V battery and ICCU issues. Our dealer has several Ioniq5s awaiting ICCU replacement for the same problem as my car, but they "can't get the part from Hyundai". While our car at times won't start, they aren't seeing that in their shop now, awaiting repairs on cars that apparently die when driving also with 12v battery problems. Our car is a lemon and we intend to retain counsel to assist us in its repair. https://www.theautopian.com/why-everyones-favorite-electric-car-keeps-stranding-its-owners/?fbclid=IwAR3yNgwVKtaGhGPd7HBz79tOV-UI1myLdmyrwDzcOJZfLarsG80b_6NJLpk

UNKNOWN OR OTHER, VISIBILITY:WINDSHIELD
Windshields in the vehicle keep breaking with little to no reason. In 6 months of ownership we have fully replaced 3 windshields. Windshields provide a line of protection for the driver and passengers when the vehicle is being operated. Continuous breaking of a windshield indicates a bigger safety issue with the manufacturing of the car/glass. In one instance there was an audible screeching sound and the glass suddenly cracked for no reason. The windshield has been replaced and safety system recalibrated 2 times in 7 thousand miles ownership with the 3 appointment scheduled for completion in a week.

ELECTRICAL SYSTEM
Pulled out of my driveway and halfway down the street, warning message pops up on display, "Check electric vehicle system". Turned down another street to head back home and receive another warning with audible beeping "Stop vehicle and check power supply". Dealership says its a known issue and to not drive it. Must be safety related or driving it wouldn't be a problem.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
On March/17/2023 @24962 miles Integrated Charge Control Unit failure + 30 AMP Fuse. Hyundai Corporate said parts back order May---June/2023 time frame. 3 inch orange circle came up on my dash with red triangle saying PULL OVER IMMEDIATELY! I was two blocks from dealership and with no problems drive to the service advisor where it died in front of them. Service advisor guessed that the pop I heard just before the circle appeared was the fuse and I drove in on the 12volt battery. I am in the Buy Back process with Hyundai Corporate Case#21170992

The car was driving fine, and an error popped up indicating to pull over and check battery. As I am going to pull over a red flashing indicator pops up saying “pull over and check battery”. As I start to pull over the car speed drops to 25 miles per hour and fully dies as I make it to the side of the road.

ELECTRICAL SYSTEM
The 12v battery died because the electric battery drained it. Ultimately, the electric battery is dead on a 1 year old car and needs replacement. The night before the failure, the car had 145 miles and drained the battery to 83 miles. Prior to that and an ongoing complaint to the dealership from November until this point, the range went from 245 miles per charge to 190 to 219 miles per charge. The 219 was after a system update in January.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
Hi! My vehicle went under a recall repair last month. Once completed, the acceleration significantly decreased in the ECO drive train mode. The other modes are working as before. I have been advised that this recall service was required by the NTSB. There are reports of this occurring on credible websites as well. I did report it to Hyundai, they didn't believe me. So, I am reporting this to you. Please fix my car!

After a few minutes of driving, the vehicle presented a warning "Check Electric Vehicle System" and then got really slow. We were able to limp back home, where it is now parked. Hyundai has not had availability to diagnose the issue.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
When driving on the interstate the collision avoidance system will falsely trigger around 5% of the times going under overpasses or road signs. The vehicle rapidly decelerates using regenerative braking.

ELECTRICAL SYSTEM, POWER TRAIN
Was in the middle of driving when a loud alert sounded and the dashboard showed the error "Stop vehicle and check power supply". The car otherwise behaved normally. I pulled into a parking log, looked at the only thing I knew how to look at (12v battery), confirmed it was still plugged in, and turned the car back on. The error was still there, but now the car wouldn't go over 26mph. I limped home, called a tow truck to take it to the nearest Hyundai that services electric vehicles, and they told me they'd have to replace the ICCU, which is backordered.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I was driving to my parents house when suddenly a message popped up on my driver screen saying that the electrical system has a problem. Driving a little more to reach my parents house and it starts saying to stop and check power supply. We ended up making it to my parents house and decided that it was unsafe to drive anymore with the error message going off. I called a tow truck to tow it back to our dealership in Fremont. When the tow came, I thought we could drive it on the bed but turns out the vehicle wouldn't start. We jumped the 12V battery and found that we could put it in neutral and somewhat drive it until it drained the external battery used to jump the 12V battery. With the car stuck halfway on the bed, we managed to put it in neutral and pull the car up using the tow's harness. Took it to the dealer and after a few days they said a fuse blew and that something called the ICCU was bad and needed to be replaced.

ELECTRICAL SYSTEM
Car is 13 months old, 13,xxx miles. Driving car at 60mph we heard a bang from the rear of the car and lost power almost immediately. Car displayed warning "Check Electrical Vehicle System." We shut it off, then restarted in limp home mode, warning now said "Stop Vehicle and Check Power Supply." We then turned off the heater and the car got to 55MPH and I could get the 5 miles back to home. The 12 volt batter no longer charges, the car will not accept a Level 2 charge. IT was towed to Hyundai for repairs. Research suggests that the Integrated Charge Circuit Unit (ICCU) and the accompanying 450V/40 AMP fuse are both bad.

ELECTRICAL SYSTEM
I was doing a 3-point turn in the driveway, and heard a pop sound from under the rear seats. A warning light came on in the dash, after a little bit of time the warning changed into an error that stated pull the car over and do not drive. OBD sensor reported codes P1A90 and P0C17. Car also went into "turtle" mode preventing it from being driven normally. Had it towed to the dealership, but took 2 weeks for them to inspect it. Once they got to it, they quickly determined it was a blown high-voltage fuse, and a fault in the ICCU (integrated charging control unit). Was told there is a national backorder on the ICCU and no ETA on delivery. I was also told I am one of three Ioniq 5s waiting for a new ICCU. I've seen many reports online of many Ioniq 5s having this same issue, and very long wait times for ICCU replacements.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
We were driving vehicle on a neighborhood street with a speed limit of 45 miles per hour. When we got a "High voltage fault warning" from the car. I continued to drive about 10 second more and got a second warning. A different series of warnings appeared the last one being "please pull over and check your electrical system". We pulled into a neighborhood street, turned off the car. We decided to try to make it home which was less than 1/2 mile. Once I restarted the car, both messages cycled through the dashboard. Then the car lost the ability to accelerate past 25 miles per hour, no matter how much I stepped on the throttle.

SERVICE BRAKES, VEHICLE SPEED CONTROL, EXTERIOR LIGHTING
The ioniq 5 has a one pedal driving mode, where the car will come to a complete stop without needing to press the brake pedal, similar to other EV's. In this mode, the gas pedal operates differently then in a conventional car - pressing the pedal approximately 1/3 of the way down represents neutral, where the car coasts. Pressing the pedal less then that - between 1/3 and not pressing it at all, applies braking power to the car, either through regenerative braking or the application of the physical brakes. The issue is, the brake lights on the rear of the vehicle do not light up when the gas pedal is depressed any amount. If you press the gas pedal as lightly as possible, the car will brake a fair amount but there is no warning to driver's behind that you are decelerating. I have twice been almost rear-ended, both times while slowing down in one pedal mode. I suspect the lack of brake lights until you take your foot fully off the gas pedal is a contributing factor. Other Ioniq 5 users have experienced the same issue.

FUEL/PROPULSION SYSTEM
The car suddenly cut speed to 20mph while traveling at around 40mph. No matter how hard I pressed on the accelerator, it did not go over over 20mph. The dashboard also said speed limited to 20mph. I had to pull over on the side of the road. Turn off the ignition. Then turned it back on. Then the car resumed to operate as normal. Luckily there were no other cars around so I could safely pull over. This could had been disastrous if it cuts speed again when I’m driving at 65mph on a busy freeway. I feel unsafe operating this vehicle because I’m afraid this will happen again in the near future.

POWER TRAIN
Heard a "pop" sound and the car shortly after said "Check EV system." A few minutes later the car beeped loudly said "Stop vehicle and check power supply." A ODB scanner reported a P1A9096 code. This issue makes the vehicle inoperable with little warning.
