“On May 5, 2025, my 2018 Hyundai Kona burst into flames in my garage and completely destroyed my Kona, Dodge Ram 1500 parked adjacent to it and my home along with its contents. Both vehicles and my home were deemed “a total loss” by the insurance company. The Kona engine compartment burst into flames after a short trip to the store. If the front door had not been locked, forcing my wife to go through the garage, we would have been unaware of the fire until it had reached the interior of the house setting off the alarms. As it was, I received smoke inhalation and a partially collapsed lung wh…”

“The 565 and 566 required to be submitted by manufacture prior to sale in US lists the vehicle manufacturer in korea, describes vehicle as a truck and weight recorded at over 33000 lbs. The vehicle has had no safety Inspections and a rather loose self certification process allows the oversight and quality assurance that the vehicle did meet fmvss and all FMVSS requirements. Simply taking a manufactures word for it does not protect innocent consumers and endangers every driver on the road. The vehicle was driven on a fully capable scale and weighed 3, 126lbs fully loaded. The vehicle has a W…”

“I purchased a 2018 Hyundai Kona, and it has had one major issue after another. It burns an excessive amount of oil, the engine misfires, and now the turbocharger is failing. I’ve already spent approximately $2,300 repairing the air conditioner and engine, and I can’t afford thousands more in repairs.”
NHTSA complaint #11751885, 2026

“The vehicle suddenly stalled while driving on the highway at normal speed without warning. The engine lost power completely, creating a dangerous situation and a risk of collision with surrounding traffic. The vehicle had to be towed to a repair shop, where the issue was diagnosed as engine failure. There were no warning lights or prior symptoms before the incident. This appears to be a serious safety-related defect. I am aware that similar engine issues have been reported in Hyundai vehicles.”

Fuel/Propulsion System 4

“My engine started shuddering and stalling out on me. This was very dangerous as the car would stall out at street lights and intersections. The check engine light only came on after the car stalled out and has not stayed on during the times that it stalls out. When I went to get a mechanic to check it out they said that they had seen many Hyundai and Kia cars that had the same issues. The issue was oil consumption. It was consuming oil faster than it should have, even though I was regularly getting my oil changed. This lead to a problem with my pistons. Now the engine needs to be replaced. But…”
