NHTSA Complaint #11633013 — 2019 BUICK ENCLAVE

This vehicles exhaust system has two brackets that broke off the exhaust due to bad welds. There is TSB out for one of the brackets where they replace one cheaper pipe but no mention of the other. This TSB is for multiple years same issue, 2019, 2020, 2021 and 2022. Yet I was told mine is not included by dealer over the phone. There are literally thousands of complaints stretched across multiple sites with the brackets breaking off and exhaust leaking into the car after. This issue is right at the back of engine. It’s leaking exhaust right into the cabin from the venting system to the point we get sick now. It’s $800 I was told to fix the 2 pipes that are faulty. Just bought this 2 years ago and have owned many GM vehicles in last 35 years not one has ever had any issue with the exhaust system. And the one pipe that broke and cost $420 for just the part is also on back order cause they have replaced way more then normal and it’s also the part that’s not under any TSB yet.
