When a car is in the process of passing me on the left during a left hand curve on the highway at highway speeds, the rear left radar sensor seems to have set off a forward collision warning. This caused the ioniq5 to do an emergency collision brake. I had to press on the accelerator to cancel the emergency brake while the other car passed me on the left. There were no cars in front of me that would have triggered a frontal collision emergency brake.

Vehicle steering or at least power steering failed catastrophically. Started with some electronic sounds at extremes of turning radius but subsequently failed completely and rendered car undriveable. Hyundai repair center attributed this to "excessive dirt and dust" or some external force, but was unable to substantiate or demonstrate any damage to parts they say need replacing. Ultimately this remains undiagnosed with regards to cause but dealer clearly identifies need to replace P/S motor and rack and pinion assembly. Insurance inspection documents no sign of external involvement in the failure. No warning lights/messages. Problem is repeatable. While failure would have been a safety risk at higher speed, it went from "noise at edge of turning radius" to "cannot steer the car" at a point in time where the car was moving at low speeds.

The yellow airbag SRS critical safety restraint wire runs exposed and loose and drooping beneth the front seats with NO space between the harness and the floor (it could have been run above the seat plate or otherwise protected. Mine snagged on something and was torn from the terminal block and has disable the airbag. Hyundai denies it a defective design or assembly and had denied warranty coverage but wants $10,000 to enable it - $6,933 for the part - $3,000 labor. The driver seat moves back and forth automatically when entering and existing - there is no control of the movement and anything more than 1/2 high is able to become tangled and disable the airbag without warning. Hyundai via emails to their legal counsel as well as customer care is fully advised but has denied warranty status or other fix or accomadation. The warrenty for this car - for which coverage has been denied - is in full force per Hyundai's express terms.
