2011 Hyundai Accent has a software problem with the coils/spark plugs. I have had all of them replaced, yet the car still senses a misfire in its computer. My mechanic looked it up and found out there was a recall for this year and make, but when I called Hyundai they denied a recall ever being issued. This will be the last Hyundai I ever purchase.
