Good morning, I have an issue with my 2020 Traverse that GM refuses to fix. I am getting warning lights from leaking exhaust. This is to due to weld defects. GM knows of the issue, they did recalls on the 2018, 2019, 2021 models but won't fix my 2020 even though it is the same issue. GM has a safety bulletin PIP5681 and PIP5681A for this issue. N222385510 is the number for the 2021 recall. The dealership has told me that this absolutely should be recalled but GM will not allow them to repair the 2020 under the same recall number. Thanks for your help!

Front exhaust pipe breaks at bracket due to poor design and ineffective welding causing exhaust leak, exhaust rattle, multiple trouble codes. Technical service bulletin PIP5681 and Special Coverage Adjustment N212356540 already exist for known problem.

- Manhattan, IL, USA

Exhaust manifold/down pipe to cat. The exhaust pipe broke just past where it hooks up to the engine block. The breakage caused exhaust fumes to enter the cabin while not moving and at idle. The vehicle has 80K plus miles so was out of warranty. I fixed the issue myself since I have the technical and mechanical know how. There never was any check engine or other warning lights. Nothing caused the issue other than normal everyday driving. I had to disconnect the exhaust from the block and after the cat. I welded the pipe back together and fixed the issue. I could have bought a replacement part for over $400, but that was not possible on our budget at this time.
