2022 Hyundai Ioniq 5 owner complaints

12 V battery died after being plugged in to charge overnight. The 12V battery was replaced in May 2024 due to a similar issue. It seems that the ICCU recalls and software updates have not been fixing the problem.

The vehicle was being driven normally on city street and I heard a thump in the rear end of the vehicle. Very soon after, got a message on screen to check electrical charging system with the indicator lights for 12 volt battery and EV system illuminating. Parked the vehicle a kilometer after thump to deliver something to a friend (the car sat for 10 minutes). Resumed driving and then within a kilometer received a message that drive power would be limited -- significant decline in drive power... put my flashers on but did not stop because on busy street with no parking ... within two blocks, message of "stop vehicle and check power supply" appeared with full drive power ending within one block -- within that block, I was able to turn down a side street and coast down a hill to a parking

Known level 2 charging issue with Hyundai Ioniq 5 vehicles. Overheating issue with charging system, previously the issue shut down charging with a temperature exceeded ~212 Fahrenheit. TSB issued that "throttles" down charging rate, irrespective of the brand of level 2 charger doubling the time to charge the vehicle. Not as advertised and significantly reducing the utility of the vehicle.

Unknowingly my cars ICCU failed. I went to charge my car on December 23. The EVSE then immediately tripped the breaker. The EVSE gave an error code of a stuck relay fault and made the EVSE unusable. This happened to 2 different Juicebox chargers and both are not permanently disabled and need to be replaced.

Was charging the car at home in my garage when the charging session stopped. Opened the door and smelled electrical burning. Was able to put the car in neutral and push it out onto my driveway, fearing that an electrical fire could be disastrous. Called Hyundai roadside assistance and they had it towed to the closest dealership that can work on EV's (35 miles away). No report yet, but I'm pretty sure it's an ICCU failure.

The car stopped both Level 1 and 2 charging. But Level 3 charging worked. When it stopped in the middle of Level 2 charging, it tripped my circuit and bricked my Juicebix Level 2 charger. Hyundai replaced the ICCU.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 24V868000 (Electrical System); however, the repair failed to prevent a failure from occurring shortly afterwards. The contact stated that while driving at 55 MPH, the vehicle was rattling abnormally. The vehicle was taken back to the same local dealer where it was diagnosed, and determined that all four tires needed to be replaced. The four tires were replaced. In addition, the contact stated that while driving at 35 MPH, the instrument panel abnormally illuminated. The vehicle was towed to the local dealer where the vehicle was originally purchased. The vehicle was later towed back to the same local dealer and diagnosed with a leak that contaminated the rear inverter. Th

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving in rain or snow the rear windshield failed to be cleaned. The contact stated that the failure was a dangerous while driving at night while the headlights from vehicles behind caused the rear windshield to become opaque. The contact questioned a dealer and was informed that the vehicle was designed that way and that the windshield needed to be cleaned manually. Additionally, the contact stated that the vehicle lost electrical power while driving at approximately 60 MPH with the cruise control activated. The contact stated that the vehicle lost motive power with several unknown warning lights illuminated. The contact pulled over, stopped, restarted the vehicle, and the vehicle functioned as needed. The contact stated t

Hyundai has absolutely dropped the ball on this Ioniq 5's ICCU and 12V battery issue. After numerous recalls to fix a hardware problem through a series of software fixes that don't work and refusal to give a loaner for loss of use, I would like to pursue a buyback option for this vehicle. On Tuesday, [XXX], I went to Napleton Valley Hyundai in Aurora, IL to complete RECALL CAMPAIGN #272 NHTSA RECALL # 24V868000. After the recall, my 12V battery went dead on Wednesday, [XXX] and had to be towed to dealership. Their only solution was yet another software update and then charge the 12V and said it was ready for pickup on Thursday, December 5. I told them then to also do a wheel alignment and they said during that process, the 12V battery went down again. They then charged it back up and gave

Hyundai issued TSB 22-01-094H for my vehicle which is an update to the battery management system,, but after 4 attempts Hyundai dealerships have still not been able to complete the TSB. Hyundai corporate has also not helped after multiple cases. After many hours of research, I have determined that my vehicle's BMS software was updated to an intermittent version (version 700x) that does not support this TSB via automatic update, and the correct BMS Rom (version 540x) must be selected manually, which the dealerships are unwilling or unable to do.

Received an error message upon starting car that said "stop vehicle and check power supply". Had car towed to dealership.

The vehicle show an error message relating to the electrical system, refused to go over 24 mph for a short time, then went completely dark with no control and wheel locked. Dealer says ICCU + fuse is at fault, but there is no date for a new part. Vehicle is undriveable until new part comes in.

Passenger side rear seat (40% side) is missing all mounting bolts required to secure seat to vehicle. I purchased the vehicle as a preowned unit and noticed squeaking and a rattle coming from the rear seats. Upon inspection, I discovered that the seat is only resting on the floor and with little effort the seat can be dislodged.

Driving on the highway the car entered limp mode allowing only 30 mph. Messages "stop vehicle and check power supply" with 12V battery indicator. Classic ICCU failure.

The car randomly stops charging when plugged into either of my Level 2 home Juicebox 40 chargers before it reaches capacity, generally after adding another 4-8% to the battery. It was impossible for me to fully charge the car without plugging it in multiple times. The service people including the EV specialist said they hadn’t heard of this problem, and it was probably due to my charging unit at home. See the attached service and repair invoice . This was not true It is apparently a well-known defect in the Hyundai and Genesis cars using this platform and Hyundai is aware of the issue. it is not a problem with my charger. It happens whether it is hot or cold and generally when it is cooler as we only charge the car at night. Please note the following: 1.Saying this was a unique is

Drove less than one mile and the car suddenly dropped from 45 mph to 20 and would not accelerate (I was almost rear ended by a bus). I was able to pull off the road and the battery died.

3rd ICCU failure. Was Driving and went into limp turtle mode. Was in a dangerous area for it to happen and took a while to get to a safe place.

Feared ICCU leaving us stranded after reading so many reported failures, took car to dealership where they inspected and did some ineffective software update, few weeks later experience EV warning light and sudden loss of power, car wont go more than 25 so we parked and were effectively stranded. Dealer suspects ICCU....great. exactly what we wasted time trying to prevent. A KNOWN PREDICATABLE PROBLEM IS CALLED A DEFECT!!!!!!

Shift gear was not engaging then i noticed the knob was slightly sticking out so I pushed it back in. The car changed gear then but it happened again a couple days later but this time the knob fell off while i was trying to push it back in. Brought to the dealers for inspection in September within a week after the problem started. Followed up twice now with no update as to when it will be fixed, I was told they will need to order part and that the entire shift gear will need to be replaced. They didn’t seem to be concerned about the safety of driving the vehicle around meantime. My husband used my car for a long trip while i was out of the country and he said the shift gear fell again. If it gets loose the gear does not engage.
