NHTSA Complaint #11545363 — 2016 KIA SOUL

I have had a catalytic convert failure 3 times in 4 years. The first was repaired with the recall on may of 2019. It was replaced at a Kia dealership, with Kia parts. I had my vehicle at the dealership a month prior due to it not running correctly. The second replacement of the catalytic converter was on November of 2020. I was driving on the interstate very early in the morning when my vehicle slowed to 15 mph, no warning lights came on. I had several other vehicles come very close to hitting me. I was able to exit the interstate which took a lengthy amount of time due to my vehicle slowly losing speed. When I was able to pull over to a safe spot my vehicle quit all together. I had it towed to the same Kia dealership. They looked it over and found the converter failed again. It was replaced with Kia parts. I have taken my vehicle in once again due to it stopped running while I was at work. The same dealership has found that for the 3rd time my catalytic converter has failed. I have also replaced all spark plugs and coil packs on this vehicle twice in less than a year due to it misfiring. My engine is also somehow burning oil exponentially. This leads me to believe there is something wrong with my vehicles engine. I also believe something is wrong with Kia parts that they only last a little over a year.
