2022 HYUNDAI IONIQ 5 Complaints

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.

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.

After a recent update at my dealer my vehicle is no longer charging at advertised time. It now takes 2 to 3 days to reach full charge from 70 percent.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while accelerating approximately 5 MPH from a stop, the vehicle lost motive power. The contact stated the failure had occurred two days in a row, with the second failure resulting in the vehicle coming to a complete stop. The contact turned off and restarted the vehicle and the vehicle operated normally. The contact stated that he placed the vehicle into SPORT Mode and the vehicle seemed to operate normally. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been diagnosed or repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Action Number: PE23011 Components (Electrical System). The failure mileage was approximately 16,500.

WHEN Home charging with my 50Amp Union installed Charger ,The Ionic5 Hyundai Overheats and shuts down charger ,.I purchased a new Charger 50 Amp. Installed by Union Electrican , Same results . I am very concerned that the Auto will catch on Fire in my garage. Please have mfg ,correct this problem This problem occurs multi times never charges more than 20 minutes

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.

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.

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.

The ICCU failed in the car. The car lost power while driving and showed an EV warning and the 12V battery warning.
