What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While attempting to park and depressing the brake the car made a sudden acceleration without input and hard braking did not slow the car. The car then impacted the curb. On another occasion while stopped at a red light the car began to move forward while the break was depressed.
Despite the severity of the impact, the airbags did not deploy. This malfunction exposed me to significant physical danger, as I was left unprotected during the crash. 3. Problem Confirmation: No,I was not aware of the malfunction of the airbags system. 4.
The contact stated that while driving at an undisclosed speed at night, all lights, including the headlights. As a result, the vehicle veered off the roadway into a ditch, coming to a complete stop after colliding with a sign. The air bags did deploy. No warning lights were illuminated.
Once the acceleration stopped, her son parked the vehicle and informed her that several warning lights and warning chimes had sounded as he parked the vehicle. The contact sustained minor soreness and emotional trauma as a result of the failure but did not seek medical attention.
My parents saw fire under the hood and my mom suffered a hand injury. They are otherwise unharmed. I know Unintended Sudden Acceleration was an issue with Ioniq EVs from 2019. It looks like it is happening to the hybrids as well. Thank you for looking into it.
Engine Code: P090A01 The Hyundai IONIQ Blue lost reverse and while driving I experienced loss of power only to regain then lose then regain (a bucking motion). The drive significantly declined. Fortunately, I was able to get back home without injury. Vehicle towed to dealership where it currently sits.
Examples of alerts we could not here were: blind spot collision warning, cross traffic while backing up, driver attention alert when hands are not on the steering wheel, and audible blinker sounds.
This car, along with several other models of Kia and Hyundai, are unsafe due to the ease with which they can be stolen. Hyundai/Kia must recall all of their vehicles that lock proper anti-theft mechanisms in the ignition, steering column, and drive train.
