What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags did not deploy. The driver got hit with steering or something in the chest and caused lot of pain for about 10 days. No internal injury was detected. The car was totalled. The car did not complain of any incident except the dash reported something binding when tried to back off from the pole.
“While stopped at a red light my 2024 Hyundai IONIQ 5, the car moved forward slowly the brake pedal became completely unresponsive and would not slow or stop the vehicle. I had to turn off the engine to bring the car to a stop.
On [XXX] at [XXX] Pacific Time , I was entering my garage when my vehicle had a surge of acceleration and went through thee wall seperating the garage from the kitchen. There wasn't any emergency braking , even with myself applying the brake , my vehicle refused to stop.
My wife was parking the 2024 ioniq and it lurched forward at a high rate of speed and slammed into another car parked in our driveway and drove that vehicle through our home garage door.
This defect presents an extreme safety hazard: when the ICCU fails to step down high-voltage power to maintain the 12V system, the vehicle experiences sudden and unannounced loss of electrical power while parked or operating, risking a total loss of motive power, steering resistance, and exterior lighting in traffic.
My wife experienced a sudden loss/reduction of power-steering assist while driving the Ioniq 5 on [XXX], accompanied by warning indicators with "Check Driver Attention Warning (DAW) system". Vehicle required towing.
Unable to charge via any AC charger. The iccu had already been repaired under an existing recall.
Was driving to vegas, it was 103-107 degrees After fast DC charging drivetrain had issues that when pressing acceleration the car would have almost a loss in power that caused a stuttering movement. If forcefully driven, the error message drivetrain electrical system would pop up.
