2020 Kia Optima LX 2.4, LESS THAN 100,000 miles on car. Car started over consuming oil 2 quarts/1,000 miles. Cranked engine yesterday to go to work and serious knocking sounds, engine is rattling severely. Losing revving power, undriveable. Smoke coming out of exhaust that smells like rotten eggs. Will be taking this to get codes run but I believe this is due to Theta II engine failure issue reported in similar cars with the same engine. KIA NEEDS TO COVER THE 2020 OPTIMA UNDER LIFETIME WARRANTY PROTECTION otherwise this is a $10,000 cost to replace engine.
