I was just checking to see if anyone else has had to replace the cats in their Tahoe's or Yukons, etc?
My 2015 Tahoe LT with 88k miles just got the oil changed and put in a software update for the brake module. Afterwards I got a CEL, took it back in and they said it's P0420 and P0430 which is both banks on the catalytic converters. We reset the light and within a few miles it was back on.
I'm just wondering if anybody has experience with this. They didn't mention anything else that could cause the fault but replacing the cats are $1700, they come as a set and they replace them all. Any chance this is a faulty sensor somewhere? and if not, this seems early for the cats to be a problem.
Thanks.
