NHTSA Complaint #11546870 — 2012 KIA SOUL

My 2012 Kia soul base, had this SC176 recall which I took it into the dealer, at that time I really didn't know exactly what the recall consisted of, until months later after researching the performance of my car, my engine lights comes on and stays on for two weeks ,then go off a day and it's back on, my car drives sluggish and it's acceleration power is bad , where it won't get up to necessary speed, and it making a loud noises when I accelerate ,which the mechanic said it's my Cadillac converter which was under recall and most likely damaged , from high exhaust gas temperatures,I do believe it's all under the last recall, my engine was damaged and should of been replaced along with the catalytic converter, I believe the KIA dealership knew of the damages but didn't replace my catalytic converter or my engine, my cars performance has gone down tremendously , month by month because of this recall that didn't work , I loved my car but sometimes I don't feel excited about cranking it up and driving it away from my house, because I'm not sure if I'm going to make it back home safe or maybe have it towed, I'm depending on Kia to do the right thing and fix this recall ,because I could be a returning customer.
