I had misfire code PO302 (cylinder 2) show up at 50,000 miles. Dealership could not find anything wrong. I questioned warranty and was assured would be covered if issue persisted. I have since had PO301 and PO303 misfire. Dealership had me pay for coil wires that were bad on cylinders 1 and 3. Spark plugs were fried and replaced at 70,000 miles (my cost). Dealership also cleaned fuel injectors which I paid for. Misfire code PO302 showed up again at 80,000 miles. Care runs ruff on startup and lunges with a/c on at startup. Any ammunition I can take to dealership would be appreciated. Covered under 10yr 100,000 mile warrenty. Original owner.
