“There is a yellow air bag (SRS) safety restraint critical wire harness underneath the seats and it's loose and hanging down touching the floor with lots of slack, very easy for a water bottle or any object to roll under there and pull it loose, which would disable a critical passenger safety system. This issue is reported by many drivers including myself, photos attached are from multiple people's experiences with this issue.”Owner report · Air Bags · Jul 2026

“I have a 2023 Hyundai Ioniq 5 Limited and had the ICCU "popped" (failed) which took about two weeks to replace. This time we were lucky that in happened at our home but had we been driving the car would it would have completed died. We regularly drive from from [XXX] to [XXX] were there are large section of [XXX] with no cell service. Meaning potentially walking for miles in extreme heat or cold. Hyundai right now seems only interested in continuously replacing the part rather than actually fixing the route cause, making it so the car is not trustworthy or safe to drive long distances.

“My Hyundai IONIQ 5 has repeatedly lost 12V power and shut down. The vehicle had to be jumped by AAA multiple times. After being restarted, it died again, and after two days of use it was dead again. I am concerned this is related to the known ICCU / 12V battery charging issue affecting IONIQ 5 vehicles, which can cause loss of motive power or make the vehicle undrivable. The vehicle is currently at Hyundai Southern States in Raleigh, NC for diagnosis and repair.”Owner report · Electrical System · Apr 2026
“While charging my vehicle at home using a level 2 charger, the ICCU failed. When it failed, it caused a power surge and my level 2 charger "exploded." It also caused the master breaker to trip, cutting the power off to my entire house. The vehicle no longer charges, will not drive over 25mph and has to be towed to a dealership for repair. Also, the level 2 charger is fried and no longer works.”Owner report · Fuel/Propulsion System · Apr 2026
“On Mar 29th, I got a 12v battery low voltage warning sign at 4pm. Jumpstarted the car and drove back to the home. On Mar 30th, car would not start so I had it towed to Downey Hyundai by roadside assistance. On Mar 30th, 12:41pm dealer confirmed that the it will need an "ICCU" and have ordered the part, but there are no loaners and no ETA for the part at this time. Problem has been reproduced and confirmed by dealer. There were no other warning signs prior to the failure.”Owner report · Unknown Or Other · Mar 2026
