Hello, I purchased a 2012 Kia Optima LX with 116k miles on it in May 2018. I was aware of the recall SC147 where metal shavings were left in the engine causing engine failure, but the Carfax indicated that this VIN was not one of the vehicles affected. The service dept rep also confirmed that. However, 3 months (and 2k miles) after purchasing it the engine did fail. Kia replaced the engine at no cost. Now, 3 weeks after I received the car back, the transmission failed. Could this be caused by a procedural error in replacing the engine, or perhaps coupling a new engine with a trans with 118k miles? It seems too coincidental, that right after the engine failed, I mentioned it to a friend and he knew someone who also had a Kia with an engine failure where shortly after the engine was replaced, his transmission also went. Thank you.
