I took my car in to Allen Samuals Hyundai dealership to have the 9C2 recall update completed on May 15th 2026. Ever since then my vehicle has had a rough hesitation or sputtering when driving. On May 18th Hyundai released a statement stating there was an issue with the update completed on the 9C2 campaign. However no resolution at the moment and to allow the car to warm up prior to driving it. I have only had my car for a little over 2 years and maintained everything a responsible car owner should. It only has 90k miles on it and had zero issues at all prior to the 9C2 campaign. I have spoke woth dealer and corporate numerous times nobody can give me a solution nor does it seem that anyone wants to. Since then the campaign has been closed and its almost as if it never existed. I do have an active case open with Hyundai 43228380 however they act as if they dont know anything about it. They are empathetic to the situation but can't really help or give a solution. All I want it my car that had zero issues prior to this update to run properly again. I dont even drive it much anymore for fear that it will mess my engine up.
