Owner report 11504345 · 2023-01-30 (January 30, 2023)
The lane departure keep system has a major firmware bug. When the car is moving along a sweeping right hand turn from the farthest left lane, the vehicle senses that the car is going to cross the lane line to the right and jerks the steering wheel back towards dead center. This throws the vehicle towards the left hand curb. The driver must react quickly to jerk the wheel back to the proper position. This takes a reasonable amount of force that not all drivers may possess. Hyundai dealer service technicians are aware of this issue but can only …

***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 …

Owner report 11488624 · 2022-10-10 (October 10, 2022)
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…

Owner report 11597774 · 2024-06-30 (June 30, 2024)
The Hyundai Ioniq was designed with a dual clutch system for the electric motor and gas motor. This was done to disengage and engage either separately when necessary for low power, regen braking, etc. However, this design heavily impacts the behavior of the brakes and safety of the vehicle overall. When the brakes are applied, the ECU will turn off the gas engine to conserve gas in regen braking mode. Additionally, the ECU will downshift the transmission. Downshifting the transmission and disengaging the gas engine become an issue because con…

Owner report 11737339 · 2026-05-12 (May 12, 2026)
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 s…
