NHTSA Complaint #11478626 — 2016 HYUNDAI TUCSON

My car seemed to be lagging severely when accelerating and then started coughing when accelerating and the check oil light came on even though I had plenty of oil and had just had it changed. I took it into the dealership and they said that the check engine light was also flashing just so fast I couldn’t see it. Several engine cylinders were apparently misfiring but it wasn’t covered by warranty. They installed new spark plugs and cleaned something to do with the fuel system and told me that would “be the starting place” several hundred dollars in. It worked fine. Fast forward 4 months I take it in for its regular oil change and mention how it’s been lagging again and here we go again. Same issue. According to my local mechanic a lot of these engines end up needing to be replaced completely to resolve the issue.
