NHTSA Complaint #11496333 — 2020 CHEVROLET TRAVERSE

We brought our Traverse into the dealership for a check engine light. The resulting inspection revealed as follows. The bracket welded from the f-pipe to the muffler at bank 2 was found to be cracked by the DeMontrond Chevrolet Dealership in Texas City, Texas where the vehicle was purchased in March of 2020. I am a non-destructive testing inspector; so, once the vehicle got home, I inspected it myself & found it to not only have a crack in the piping but also severe lack of penetration in the welds. Both of these are original manufacturing workmanship defects. The resulting defects present severe health hazards as the vehicle now leaks CO₂ in a location not visible unless inspecting the exhaust system & as the stress fracture grows around the piping it could eventually result in the piping breaking through or loose under the vehicle while driving down the road. If the piping were to break through then the vehicle would no longer be in compliance with the EPA for emissions by a long shot. As it sits the vehicle will fail a state inspection due to the permanent code the computer is throwing from the leak. The above listed hazards have already been noted by the NHTSA in Bulletin No. PIP5681C & in Special Coverage Adjustment N212356540 Front Exhaust Pipe from GM. The bulletin only states the issues; however, the special adjustment provides the 2019 Traverse drivers with an extended warranty for the above listed issues. I would like to request that the 2020 Chevrolet Traverse be considered for the same extended coverage of 15yrs or 150,000mi via GM for the cost of the replacement of the f-pipe, three gaskets, & the muffler as these are original manufacturing defects. If it was not for the vehicles check engine light coming on these issues would have gone unnoticed until an even further point in time taking us further away from the original warranty of 2yrs or 24,000 which is clearly not a long enough period for these issues to present themselves & be corrected.
