When i did an oil change on my sportage i turned on my car and it started making a loud noise and it was shaking with alot of turbulence, it was yanking and forcing itself it felt like it was going to shut down it was a scary feeling since i was driving it and all of a sudden it went to being driveable up to 20 to 15 mph. i saw there's a recall on the hyundai and kia, included are the 2013'2014 hyundai sonata and santa fe, 2011'2014kia sportage, 2011'2014 optima, and 2012'2014 sorento. during machining of the engine crankshaft and crankpins, metal shavings may have been left within the crankshaft oil passages, and the crankpins themselves may be too rough on the edges. as a result, oil may be blocked and cause the connecting rod bearings to wear, which would then cause them to fail and seize the whole engine. that, of course, would cause the car to stall during driving.
