   GM published bulletin PIP5681A on 10/05/20 regarding defective welds on the exhaust brackets near the catalytic converter. I had the same exact weld failure and GM is not honoring the warranty coverage, even though their bulletin said that all 2020 Traverse SUVs were included.

   This is a know issue on 2021 models. The exhaust bracket is breaking away from the muffler/catalytic converter. The weld is breaking causing the exhaust to break away and both pipes must be replaced resulting in a 1500 repair. Why if it bad in later years is there no maintenance bulletin or mandatory fix for the 2020 models? It was repaired and fixed by McClusky Chevrolet in Cincinnati OH.

    We have had multiple issues with the exhaust system and the brackets that hold the catalytic converter in place. The catalytic converters have been replaced two times in the last 3 years with them currently needing to be replaced AGAIN. This is supposed to be our family car and it is in no way reliable. Not when we have to take it in every couple thousand miles on it to have the exhaust system repaired. We have had it into the dealership multiple times to confirm the…
