Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The system lost its ability to audibly warn me of various conditions that were a risk to everybody in the car. 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. After the loss of the audible alerts, I nearly collided with vehicles that were in my blind spot because the alert was no longer present.

I am not sure who to report this to, but NHTSA and Hyundai corporate office both report the car as having no recalls. The local dealership says it has 3, 2 for computer errors (my car currently has a computer error). When I asked the main Hyundai support people about this, they stated local dealership and the corporate office have different systems. I can concerned Hyundai is hiding recalls from the public by keeping them on a separate system at dealerships and not on the main website or NHTSA.

What component of system failed or malfunctioned? Sudden deceleration, not sure what system this is a part of. Is it available for inspection upon request? No, I don't know what is causing the problem so have not been able to have the specific system looked at. How was your safety or the safety of others put at risk?

Has the vehicle or component been inspected by the manufacturer, policy, insurance representative or others? Yes, by four separate dealerships. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

The contact owns a 2019 Hyundai Ioniq. The contact stated that while attempting to park into her son's parking pad, the vehicle independently accelerated reverse while in the reverse(R) position. The vehicle initially hit a gutter on the side of the house; as the vehicle continued to accelerate, the contact forcefully depressed the brake pedal but to no avail.

The vehicle then hit a tree as she stood up on the brake pedal which finally stopped the acceleration. The contact immediately placed the vehicle into park and exited the vehicle. 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. A police report was not filed and the vehicle had yet to be towed. Her son's porch column and downspout gutter were damaged as a result of the failure. The manufacturer was notified about the failure and informed her that there were no recalls on her vehicle.

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. Until this is done, all American auto dealers and insurance companies must refuse to sell and insure any new Hyundais and Kias.

My 2019 hyndai ioniq electrical system stopped working and results in the front door claiming that is not open. An internet search showed that this is common many hyundais and in particular the ioniq. The issue with this is 1) there is no way to know how bad this electrical issue, 2) since the door may or may not be open, the risk of the door opening while driving is present, and 3) all other notifications on my dash are no longer usable; i have no way of knowing fuel left, mpg, or any other safety warnings on the dash. Finally, the issue creates a constant beep that does not stop. This is a safety issue seeing as it is so loud, it makes being aware of the sounds around us nearly impossible to hear.
