Replaced original manifold cat last December with OE Kia--that cost about $2200 doing it myself. After 5K miles I was getting a pending P0420. Endoscope showed cat inlet center section bubbling...looking like melting had started.
The one I got a few weeks ago was from a dealership in Florida and was unopened, in the bag with the Kia seal on the outlet end of the cat. DON’T get aftermarket when OE is available for this price. Trust me.
Around August 12th my son was driving my vehicle and my motor blew!! I was truly lucky they were able to to get Kia to replace motor but the damage was already done to my catalytic converter so they said I had to replace that!
I had a 2019 Kia Rio S bought new. It was a spunky little car that I could get about 40 mph on. Had no issues with it until it hit about 5 years old at about 80k miles with an engine misfire. Took it to my mechanic and they couldn't get it to happen again. A few thousand miles later, catalytic converter started going bad.
the older Kia cats were garbage, Ive replaced hundreds of 0420 cats under a recall on Souls.
It blew my catalytic converter and was on the road to a dead engine after Kia paid thousands in warranty repairs to not fix the engine.
