I called Chevy today and they said my 2019 Chevy traverse had no recalls besides the air bag and they couldn’t do anything even with the bulletin which was posted on this forum. I am not sure what to do. Chevy a year ago said I had a hole in my exhaust pipe and told me to go to a muffler shop to get it fixed because they wouldn’t have the part. The muffler shop said they didn’t see any holes but the bank 1 and bank 2 O2 sensors were messed up. They replaced those and said I still had a code for a misfire and replaced the spark plugs. Now I am back to thinking it was the exhaust pipe in the first place after reading over this forum and the bulletin. Now I have no idea what to do from here? I went to another dealership today and they think it could just be my converter. I am at 100,000 miles. Any advice?

What is your original problem / symptom(s)? What codes are you getting?

We really should have a sticky on this topic that lists the available service bulletins and extended repair coverage available for 2018+.

Best I can tell there are three bulletins available on the all too common 2018+ exhaust system issue.

1) Is a bulletin for 2018-2019 models, but it does not have any special warranty coverage wording in it. Just states "For vehicles repaired under the Emissions warranty" Here: https://static.nhtsa.gov/odi/tsbs/2019/MC-10165909-9999.pdf

2) Is a TSB offering 15yrs/150K mile coverage on 2019 models: N212356540 Chevrolet Technical Service Bulletin

3) Is a TSB offering 15yrs/150K mile coverage on 2021 models: N222385510 Chevrolet Technical Service Bulletin

From the looks of it, 2019 and 2021 owners should not have to pay for this repair for a long time. Why 2018, 2020 and 2022+ aren't covered is beyond me.

I agree.... I see no difference between the 2019 I owned and the 2023 I currently own. It makes no sense at all.

I'm not a mechanic, but as per this bulletin is the flex pipe located within the CC and the mid exhaust assembly?

Here is a pic of my '23 exhaust and yes, the flex is part of the pipe before the mid exhaust section. If you look right in front of the flex, you can see the connection that is the problem. Not the clearest pics but this was the best pic I could get right now.
