“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.

The vehicle is currently at Hyundai Southern States in Raleigh, NC for diagnosis and repair.”Owner report · Power Train,Electrical System · Apr 2026

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.

Also, the level 2 charger is fried and no longer works.”Owner report · Fuel/Propulsion System · Apr 2026
