ELECTRICAL SYSTEM
The car started reporting error messages including "Stop vehicle and check power supply". It briefly went into limp mode before dying completely. Flat bed to dealer who can't begin diagnosis for at least a week. This sounds identical to the ICCU issue that many owners are experiencing.

My 12v battery died on 11/12 while my main battery still had 52% charge remaining. Had to jump the battery to get the electrical system to work. Since then several of the cars electrical systems are not working. This is a known issue online that Hyundai has responded to but the dealer is saying that they are not aware.

SERVICE BRAKES, POWER TRAIN, VEHICLE SPEED CONTROL
Every so often when I am driving on the highway, the car just looses power and I may catch a message that flashes on my display, "Emergency Braking". The event last no longer than about a second. When this phantom braking happens, so far, it has not been so severe to feel dangerous just unsettling!

The car suddenly showed a warning on the screen asking me to park and in a few seconds went completely dead. It won't start at all. I can't even unlock the car. I had to call roadside assistance and have them tow the car to Ideal Hyundai dealership in Frederick, MD. It's been 4 days and the dealership can't diagnose the problem or won't communicate what the issue is.

ELECTRICAL SYSTEM
I charge my vehicle using a home 48 amp charger. After about 10 months of ownership. I began to receive “charging unsuccessful”notifications after about ten of charging at the Maximum charging speed. I reduced the charging rate to Reduced and was able to charge continuously to 90% a couple times at that rate. However, I began to receive “charging unsuccessful” notifications at this rate as well and had to lower the charging rate to Minimum in order to charge continuously. I can not charge the vehicle at 48 amps and the vehicle can only charge at 5.7 kwh, rather than the expected 11.5 kwh. The vehicle has been repaired four times. I cannot take the car on long trips, or for intensive use, where I would need to quickly charge to car in order to continue using it. As this issue appears to be progressive, when will the car fail to charge at even the Minimum rate? When I am on the road at a remote charging station? When I have an emergency and need to use it?

ELECTRICAL SYSTEM
We had charged the Ionique 5 to 90% and driven for short trips. We parked it then went to do some errands about an hour later. The dashboard warned that the 12 V battery was almost completely discharged and that I should start the car by placing the key fob next to the start button. I did that but it didn't start. I pushed the off button and then tried again and it refused to start and the dashboard flashed somewhat erratically. The battery then went completely dead. We called the emergency roadside assistance and they came within 30 minutes but the person who arrived said he knew nothing about electric cars and so we asked him to leave. Later we searched the internet and found others have had the 12 V batteries discharge. We also learned it could be charged with a portable charger. We called the dealer as it was now Sunday. One of the salesforce managers reassured us that is was OK to use regular car chargers on the Ionique 12 volt battery. Our neighbor helped us do this and it then started working. We followed the internet (a blogger's) instructions to go to the utility site and put it in the mode that would make sure the 12 Volt battery was drawing on the main powertrain to completely charge. We left the car on for 30 minutes and then it seemed to be working normally. We did some errands and it continued to work well. The safety risk is if this had happened on the highway and away from home. The car was recently taken in for the scheduled recall of ? something before this happened. There were no warnings or symptoms prior to this incident. There was several months ago an episode when I was driving that the power seemed to decrease and I was unable to accelerate and drove about 2 miles on mostly city streets at about 20 miles per hour. After I shut the car off and then my husband tried to start it the next day, it worked fine--that was the only other incident. I did not report that and it did not recur.

POWER TRAIN, ENGINE, ELECTRICAL SYSTEM
The vehicle lost traction power, failed to respond to presses to the accelerator and coasted to a stop. It gave no indication on the dash that there were any problems. Putting the car in park and then selecting drive again restored traction power and the car responded to pressing of the accelerator pedal. The car was not turned off and back on. During the incident: - The brakes, steering, air conditioning, radio and other electrical equipment continued to operate normally. - The car was configured for "Level 2" regen braking, but during the incident, when all pressure was removed from the accelerator pedal, the car did not "feel" like it slowed as normally did during Level 2 regen when there is no application of the accelerator. - The car was configured for "ECO" mode. The drive mode was switched to Normal and Sport during the incident but it had no effect. - The Power/Charge gauge on the dash neither indicated Power when the accelerator was pressed nor indicated Charge when coasting (as would be expected for Level 2 regen) or when the brake pedal was pressed. Car Information: - The car had about 75% charge and reported about ~260 miles of range. - The manufacturers app has not reported any "DTC" codes. - The car has no open recalls at this time. - Service Campaign 997 was completed August 23rd at dealer. - Service Campaign 9A1 was completed August 23rd at dealer. Additional Information: - A previous event similar to the above described event happened on August 21st where the vehicle lost traction power but gave no indication that anything was wrong. - Reported it to the dealer, but they were unable to find anything wrong or recreate the problem. - They applied the ICCU software update.

Vehicle suspension in the rear feels unsettled when coming to a stop using regenerative brakes. If you hit a small pothole or recessed manhole cover the rear of the vehicle feels like the rear suspension is jumping. I've taken it to the dealer and they noticed it and also it occurred on a new ioniq 5 they had on the lot also.

ELECTRICAL SYSTEM
We have owned an Ionic 5 for a year. For 8 months the level 2 charging system worked fine. We have two 40 amp level 2 chargers at two different locations which both charge the car at between 9.0 and 9.2 kW, well below the Ionic 5’s advertised capacity of 10.6 kW. After 8 months the charging session began to fail after only 1.5 hours due to the charge port overheating. Initially this seemed to be related to the ambient temperature, but now the failure occurs even when the ambient temperature is below 70. Once the session fails, the charging system keeps cycling between starting and failing, with each cycle lasting only a couple of minuets. Therefore it is very difficult to charge the car to even an 80% capacity. I am also worried about the impact this constant cycling is having on the battery overheating as well as the life of the battery.

ELECTRICAL SYSTEM
In the 1.5 years since I bought the 2022 Hyundai Ioniq 5 (new vehicle) there have been three instances where the car has failed to turn on or off due to rapid discharge of the 12 V battery. In all three occasions, the main battery was fully charged; however, the 12V discharged rapidly. The first two times this happened it took about 20 to 30 minutes of waiting for the main battery to charge the 12V battery before the car would start; however, on the most recent occasion, I had to call a tow truck in order to get the car jump started. I am very concerned about the safety of myself and my young children as I regularly use this car to go to work and take my kids to school. The only warning sign was a yellow light on the dashboard of the car—the indication that the main battery is charging the 12 V battery (this was happening more frequently leading up to the 3 instances, which tells me that the 12V battery needed charge, but was being insufficiently charged by the main battery). Because of the poor 12V battery, I avoid using functions that could deteriorate the 12V battery, such as air conditioning, and the GPS system. Hyundai recently sent a letter/safety notice about a faulty ICCU and fuse, and I will be taking the car in soon to get this repaired, but the repeated discharges of the 12V battery in the last 1.5 years has deteriorated the 12V battery enough that Hyundai should be proactively replacing it (not just the ICCU and fuse).

The vehicle will not fully charge at home at night on a level 2 EVSE. It charges for a few minutes, than stops entirely. When I restart the process, the same issue remains. I cannot charge the car fully at Level 2, 40amps. I wake up in the morning and only 5% of charge has been added.

When my car is plugged in to charge it keeps stopping the charge. Example: Starts at 24% and stops at 28% I restart charge and it stops at 47%. Each time the charging port on the car is hot. This has happened multiple times. I now have to set reminders on my phone to check that my car is still charging so I can get to work in the morning. I am at the dealer now and they say there is nothing they can do because they have not been notified that it is an issue Thank you for your attention to this matter
