“On 3/27/2020 I purchased a Hyundai ioniq 2020 which advertised on the window sticker vehicle includes advanced safety features bind spot collision avoidance assist and rear cross traffic collision avoidance assist. Unfortunately, the manufacturer notified me on 8/24/2020 that the vehicle was not manufactured as advertised. The features can't be added after the manufacturing process. The manufacturer offered me $500 for my inconvenience when I requested a vehicle buy-back to repurchase the like kind vehicle with the included safety features.”

“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. …”

“***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. …”

“While on cruise control when climbing a hill, a warning appears telling me that the EV has failed and that I should stop driving the vehicle. At the time the warning appears the cruise control shuts off and the car slow dramatically. All 5 times this has happened the vehicles behind me have had to slam on their brakes in order to avoid running me over. Once it was a triaxle dump truck, fully loaded, he went off the right side of the road and almost hit the guardrails to avoid the collision. The car has been tested at our dealership (Jenkins Hyundai) and they have confirmed the issue.”

“My horn failed and was replaced in March of 2021. It stopped working again in January of 2022. The dealer replaced the horn the first time and another horn is on order with an unknown date of when the part will be available. This is a safety concern for me. I drive in the country and many deer run in the road. There has also been an incident where a child ran infront of my car while in my home city. Not having a horn poses a risk to me and others. I would not expect a car that is less than 2 years old to have a horn go out twice. I have driven 50 years and have never had a horn break. …”
