This was only the beginning of the issue. PO303 cylinder 3 misfire has been a chronic problem since then. The EGR Valve was replaced in April 2018 (and additional $800 +) Unfortunately the hidden warranty for that EGR valve replacement expired on 3/31/2017 though with unlimited mileage coverage. I came close to having help with that one.

The check engine light came on and stayed on, but of course when I took it to the dealer they couldn't duplicate the problem and just reset the light. Now it's started hesitating more often, but won't set the code. I often wonder as far along as the technology is in these cars, if they can set the computer to "Not Detect" certain issues that may reoccur.
