“my Kona sputters when I put it in gear EVERY TIME. I have purchased gas at several stations so getting bad gas in the tank cannot be an issue. I’ve also had to replace the coil packs twice within 6 months. December 2024 and July 2025”

NHTSA complaint #11673219, filed 2025-07

“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. …”
