Engine Failure problems of the 2013 Kia Motor Soul

Driving home a few weeks ago my kia stalled on the interstate, stopping me in in heavy traffic with out warning. I was able to get it safely off the road after it started back up. When it started it started blowing all kinds of white smoke, ran really rough, all the dash lights came on, and I noticed the engine was now knocking. The next morning I got it towed to kia dealer where they did some work under recall sc176 which was a failed computer which over heated the exhaust converter which resulted in internal engine failure due to back pressure and combustion. My engine now has a failed engine connecting rod. Kia did the basic recall work but now is refusing to replace the engine under their own recall. As it states right in the recall. If the catalytic converter is damaged, substrate particles can enter the engine combustion chamber and cause abnormal engine combustion. Continuous abnormal engine combustion can result in damage to one or more of the engine's pistons which can cause piston rod breakage, potentially puncturing the engine block allowing engine oil to escape. Engine oil that contacts a hot exhaust surface may result in a fire. In addition, the catalytic converter will also be replaced if it has been damaged. Depending on the extent of any damage, the engine may also be replaced. This car I have owned since brand new 1 person owner and was running perfect up until this event. The engine failed due to the issues of the recall and now they refuse to replace the engine that it is clearly listed din black and white on their own recall information.

Was driving my 2013 kia Soul and it threw a rod and my engine locked up. I found out that there was a recall on the catalytic converter. Dealership said they tried to run a diagnostic and it said engine failure after they replaced the recalled catalytic converter.

Fuel efficiency had declined greatly over past month. Car stopped working and had it towed. The kia dealership replaced the started but said the engine had a knocking and needs replaced. Has only had kia work on it and all regular maintenance has been done. Checked the recall and say my car is not covered, yet the engine failed out of the blue with no warning.
