Loud knocking sound coming from engine, then check engine light came on. Made to dealership and discovered a bad oil pump caused metal to flow into the engine and wear the connecting rods and destroy the engine. Kia knew there were problems with the 2012 kia Optima 2. 4l engine and yet did nothing to rectify the issue. Now they want me to pay $6000 for a new engine when they knew there was an issue with the 2012 Optima all a long.
