What 2020 Hyundai Ioniq Hybrid owners say
Electrical system
***2020 HYUNDAI IONIQ TURNS ITSELF ON, WITHOUT HUMAN ASSISTANCE OR MODERATION. HUMAN DOES NOT NEED TO BE IN THE CAR FOR THIS TO HAPPEN, MEANING IT COULD OCCUR 24/7, SANS DRIVER, AND IS A SAFETY ISSUE.*** *Months of random electrical odd events. Example: the car does not know it's off or Not shifting correctly *June 6, 2023 - 8am - I entered the car and got settled. The steering wheel is locked...it was not like that the last time I was in the car. I turned the car on, shifted to reverse, and the steering wheel remained locked. I couldn't fix it so I decided to get out of the car and call for service. *June 6 2023 - Attempting to leave the car. Put the car in park, set the parking break, turned car off, and opened door to get out. When my left foot touched the pavement the Ioniq turn itself back on. I thought I had messed up but nope. I took several videos. …
While attempting a slow right turn from a complete stop at an intersection, I heard a loud thunk sound followed by an immediate loss of power steering response. The steering wheel spun freely with little resistance while the front tires did not respond proportionally. I was able to safely pull over. Upon restarting the vehicle it produced an abnormal wheezing sound suggesting additional mechanical stress. At the time of the failure the vehicle had approximately 40,000 miles, which I believe represents a premature failure for a safety-critical steering component. The vehicle was brought to a Hyundai dealership for inspection. The dealer pulled diagnostic fault codes, found none, performed a 20-minute test drive, and returned the vehicle stating they could not find anything wrong. No physical inspection of the steering components was performed. …
Body & structure
The contact owns a 2020 Hyundai Ioniq. The contact stated that while driving approximately 35 MPH a sudden booming sound occurred near the front passenger's side of the vehicle. After stopping to inspect the vehicle it was discovered that the front driver's side wheel well and bumper dislodged and was rubbing against the front passenger's side wheel. The contact was able to adjust the damaged body part from rubbing against the wheel and continued to drive the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 46,650.
