Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I experienced sudden unintended acceleration which propelled me over a curb, up an embankment, over a boulder and into a fence. I could have been killed or I could have killed others because I had no control of the car. The Hyundai corporation will not acknowledge this. The car was inspected and declared a total loss and is being moved to a location where it can be stored at no cost. There was no warning. Also this exact incident occurred with a Hyundai Kona I owned. That incident occurred on January 8, 2026.”
NHTSA complaint #11736293, filed 2026-05“Sudden uncommanded high engine revving 4000 rpm with loss of forward acceleration while driving. ISG (Idle Stop n Go) indicator on dashboard turned yellow and system could not manually override. Vehicle was turned off. After car turned back on after about 30 minutes It entered a Protective Limp Home Mode, which cleared the systems. All seemed back to normal. It was advised to have vehicle towed to the dealer where purchased. The vehicle has only 4,000 miles and 9 months old.
