ELECTRICAL SYSTEM
ICCU failed post software update. Driving home and was suddenly alerted electrical vehicle systems were malfunctioning, and shortly following (1 or 2 minutes), the car flashed a new warning telling me to stop the vehicle. Had I been on a busy highway or a one lane street with low visibility, it would have put me and my wife in danger of being struck by other traffic. Luckily, I was very close to home so I drove home and did not drive the car for a few days. while researching what to do, I had read about the ICCU failure and my problems were similar. I called a tow truck to get it out to a dealer. When attempting to shift the card into drive or reverse, the car would not move. Dealer has determined that my ICCU is in fact bad and is currently in the shop being replaced. Unknown how long this will take.

TIRES
Sound deadening foam inside the tire delaminates and causes SEVERE wheel imbalance. This is a widespread issue on all the Hyundai Ioniq 5 forums with this tire. Mine cost me $300 and countless hours to diagnose. IT also severely impacted the cars handling and prevented the car from driving over 46mph (in my case), which is extremely dangerous on interstates. My local tire shop balanced the tires with the maximum allowed amount of weights, but then the vibration was still there at 59mph. The Hyundai dealer then diagnosed it and they charged me $180 to do a dynamic balance. According to their results, the tires were "bad" and needed to be replaced. I went to Costco to replace the tires at a cost of

UNKNOWN OR OTHER, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I bought my Ioniq 5 in April 2023, starting in June 2023 I started having issues with the internal navigation system locating my vehicle on a different route than I was actually on. When I connect to Apple CarPlay to be able to use Google Maps or Waze, it also throws my cell phone system off and will be taken into wrong streets. Vehicle navigation also detected me driving in the wrong direction alerting me not to enter the street. I took video and photos to the dealer starting in June 2023 for a few months. They first updated the software which took over 6 hours, and my car spent the night at the dealer. Unfortunately it did not resolve the problem, they then replaced the antennae also not resolved issue. They replaced the camera in front of the rear view mirror, also no resolution. Lastly they replaced the head unit under warranty. My car continues to have the same issues with navigation and recently while on the freeway and the navigation and Apple CarPlay were acting up, when i switched lanes it alerted me of a collision and car began to break while driving 65 miles per hour. This could have caused me to be rear ended if there would have been a vehicle behind me. I do not feel safe driving this vehicle which i depend on the navigation maps for my daily work. Currently i am avoiding driving on freeways to ensure the car does not suddenly brake and cause me to be rear ended. I contacted the dealer and they stated they have not detected the same issue on other Ioniq 5's sold at Puente Hills Hyundai in California. In researching through the internet, i found there are others experiencing the same issue. Dealer asked me to bring my car in once again, but i am not sure what they can do. Hyundai needs to figure out the issue on the Ioniq 5 navigation system and issue a recall to fix the safety glitch with the system.

ELECTRICAL SYSTEM
I was driving 45 miles per hour on a 2 lane highway, when the car suddenly started beeping, lurched, and dropped to 25 miles per hour (low power mode). After pulling over at a gas station, I was able to run the car in this low power mode for a short time, and then the 12V battery completely died. The main battery in the car was at 78%. There was no warning light that this would happen before making that drive. I took the car in to the dealer and they informed me that the ICCU failed. I see that there is an investigation underway for the 2022 Ioniq 5, and that the 2023 Ioniq 5 has the same components. Please take this investigation seriously as if I were going on a faster highway or more cars were around, it could have resulted in a major accident. This car has just over 10,000 miles and was just purchased under a year prior at the time.

POWER TRAIN, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
First indication something was going awry was when attempting to charge the car. Heard normal click indicating charge had started, but no audible announcement that charging had started. Car started throwing "Check electrical system," then power plummeted and became unresponsive to accelerator, followed by "Stop car. Check electrical system," then finally something like, "Battery is being discharged by external devices."** Car had to be towed about 60 miles to nearest Hyundai EV service center. Eight days later, I got a call from service saying that the ICCU needs to be replaced. They will update me once ETA of part is known.

ELECTRICAL SYSTEM
Electrical system warning lights came on and loud alarm indicating the need to stop the vehicle immediately. Diagnosed by mechanic as ICCU failure and associated 12V battery issues—so, typical Ioniq5 problems. Just lucky I wasn’t driving on the highway.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was driving at night on a freeway marked as a 65mph speed limit. I had the adaptive cruise control turned on and set to automatically follow the road speed limit. There was intermittent rain at the time. Suddenly my car began to accelerate, but I was able to stop the acceleration by stepping on the brake to disengage cruise control. I tried re-engaging cruise control and it immediately accelerated strongly again. That is when I noticed the cruise control speed had been set to 85mph. I disengaged cruise control for the rest of my trip home and was able to drive normally. Subsequently I learned that the car detects speed limits by both map data and visually recognizing speed limit signs, so I assume it mis-identified a 65mph sign as 85mph. The auto speed feature set the cruise control speed to 85mph even though that is much higher than any possible speed limit in California. I disabled the auto speed feature of the adaptive cruise control and have not had any problem since then.

UNKNOWN OR OTHER
I attempted to drive my car to work. The car started but would not shift into gear. A red battery light indicator was on in the lower left corner of the screen. I contacted my dealer and they asked me to jump my car and bring it in. I did that. They indicated that my car had experienced ICCU failure and that a part would need to be ordered. The car had already been updated to address the ICCU failure, or so I thought. This is a known issue with 2022 models.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, POWER TRAIN
The vehicle made a loud popping noise and lost motive power. Dashboard lit up with battery symbol and said to check electric vehicle system. Dealer service is certain it is an ICCU failure. The vehicle had the software update to “fix” the ICCU issue thousands of miles ago.

FUEL/PROPULSION SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
The car loses power, slows down dramatically, and will not respond to the accelerator pedal. This failure has happened twice. The first time I was driving at about 40MPH on a side street when the car started slowing down with no warning and limped along at about 20MPH. I could not get it to move faster so I put my flashers on and made my way to the side of the street, pulled off of the road and shut the car off. When I restarted the car it drove normally. I reported the failure to Hyundai and they had never heard of this happening. They kept the car for 2 days and couldn't replicate the problem. That was about 2 months ago. Yesterday, 3/4/24, I was on the freeway going about 74MPH using the smart cruise control. I had just changed lanes when the car lost power and I got the message, "Smart cruise conditions not met." My speed dropped to the low 40's as other cars were whipping past me. Even though I floored the accelerator I got no response. I started the flashers, made my way to the right lane and got off on an exit ramp. I pulled off to the side of the ramp, parked the car and turned it off. Once again, when I restarted the car it performed normally. This is very dangerous! I could have easily been rear ended by another, faster car on the freeway since I slowed down so quickly without braking lights lighting. I brought it back to the dealer again today and they have kept it to run diagnostics. I don't expect that they will find any problem this time either.

ELECTRICAL SYSTEM
12v battery died this morning. The car main battery had 77% state of charge and still the 12v failed. The main battery is supposed to charge 12v as long as it is above 20% state of charge. This seems to be a wide spread problem and Hyundai is not taking any pro active steps in resolving this. All recommended TSB (Technical Service Bulletin) has been applied on the car and car was serviced last week and passed the multipoint inspection.

FORWARD COLLISION AVOIDANCE: WARNINGS, BACK OVER PREVENTION: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION
3 issues: 1. 2 x, driving over a hundred miles the sensors get faults. None of the sensors work. Does not detect other cars. They updated my firmware, wiping the faults. 2. Once stopped at stop light, the sensors can start detecting items not there. 3. When parking the car does not detect items that are there. (I have video, dealerships so far refuses to fix) I am still trying to get them to fix it. Additional concern, talking to other drivers, they have similar issues and responses from the Hyundai dealerships. This is for both the Ioniq 5 and 6. Pictures: shows no other car image, or sensor detection. I took the picture a behind to give context. I can provide the videos if needed. Answers to question, separated with a comma: Yes, answered above, trying to get confirmed, the car has been inspected by Hyundai service center, and the errors were wiped by a update + reset.

UNKNOWN OR OTHER
Vehicle was taken to dealer for recall repair. Upon completion i made sure everything was good to go. And realized the navigation system was not updating. Service agent took it back and was advise it needed a 4 hour update. Car stayed overnight. Following day they informed me they couldn’t find the problem and were in contact with tech support. They were advice to just replace the navigation antenna. Dealer has place the order for the antenna. My only problem is while we wait for the antenna my car’s location is at a random place so if it where to be taken there wouldn’t be a way for me to know the location of it.

UNKNOWN OR OTHER, EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM)
The navigation system in this car has an additional feature which is always enabled even if a destination is not programmed into the nav system which is supposed to warn drivers if they are going the wrong way on a highway. Intermittently the system erroneously indicates that the driver is going the wrong way. A voice warning is repeated issued and a warning symbol is displayed on the instrument panel. It is shocking, very distracting and frightening at first. Then it becomes a driver irritation, and eventually the driver tries to ignore the constant warnings, completely defeating the purpose of the safety feature. I’ve seen on the Ioniq forums where other drivers have reported this intermittent problem. Our local dealer would not check our car because the nav system was not failing at the time we brought it in. The problem can last for 5 minutes and then stop or can last for a duration of a car trip. For drivers unaware of this problem, they could easily be frightened enough to cause unsafe driving.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
12/30/2023 at approximately 5:30pm I drove home with the iPedal engaged. The iPedal was installed as a download to the car in August 2023. My daughter was in the passenger seat. I began to back into my driveway but shifted to Drive to straighten out the car. The car began to roll forward I took my foot off the accelerator but the car did not stop in spite of the iPedal being engaged. I put my foot on the BRAKE PEDAL which went all the way to the floor to no avail. The car rolled slowly into an electrical pole which brought the car to a stop. I previously filed a complaint here but I have since learned that iPedal may disengage if the car is put into reverse. There is not warning light to alert the driver that iPedal is disengaged so the driver is not aware that the brakes may not work as expected. I believe this may have been the case with my accident. However, this does not address why using the foot pedal for the brakes did not stop the car. Have found many complaints about this on various forums and believe this aspect of iPedal needs to be addressed. It should not disengage unless the driver instructs the car to do so. I have not been able to find documentation of this functionality in the manual, but I have searched and will continue to do so.
