Hello all. Recently joined the X community (Xmmunity?) with my recently acquired 11' P4X.
So excited to start modding and do some Overlanding/light off roading.
Unfortunately, my rig is back at the dealership already after a P0430 code kept popping up. I even reluctantly bought an extended warranty (which I negotiated the price down on) but it conveniently doesn't cover cat converters (so lame).
But spoke to the GM at the dealership and he said they would make it right.
I guess my concern is, after you replace the cats that need replacing, what is going to stop this from happening again?
What is the root cause of the cat failure in these engines if it isn't structural (like something smacking it)?
Has anyone done anything to remedy this problem on your 4.0 so it doesn't come back? Too many issues to isolate? Too many questions and I should shut up now? Got it.
Thanks either way errbody. Happy to be part of this community and glad I found this forum.
