Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The horn on my 2020 Hyundai Ioniq has stopped working. I checked the fuses and they are all good. Hyundai currently has several other models with recalls or at least known to fail. Yes my vehicle is available for inspection and no I have not had it looked at yet… dealer wants to keep it for 3-5 days to diagnose and further, given the nature of the issue, I don’t feel I should be responsible for any fees involved in doing so. It poses me a major safety concern as I cannot warn other cars of potential collision etc. …”
NHTSA complaint #11714201, filed 2026-01“***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. …”
NHTSA complaint #11526534, filed 2023-06“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. …”
NHTSA complaint #11454055, filed 2022-02“Car has two horns, both STOPPED working completely about 2 1/2 years ago and were replaced by the Hyundai dealer in Florence, SC. High pitch horn failed again about 1 year ago, and low pitch horn has now failed. Local Hyundai dealership in Pensacola, FL npow wants $800 to replace what should be fully covered. Car now has 75,00 miles so they say it us out of warrenty. But, a safety issue on a known problem (per Hydai frum on line and personal experience) should be fully covered by Hyundai.”
NHTSA complaint #11648730, filed 2025-03“On June 10, 2021, when driving from Topeka, KS to Park Ridge, IL, there was a failure in both the Adaptive Cruse Control System as well as the Lane Keeping Assistance System. The ACC system started the car moving forward from a complete stop without my intent and the LKA turned the car to the right striking a semi trailer that was completely stopped. Additionally there was no warning from the Forward Collision Warning system”
