I am sure this was an issue to begin with.

For the last year or so my car keeps making this really loud noise and it gets worse within hours/days. We have had it in 3 maybe even 4 different shops to have an exhaust fixed. One shop said that a part of it was never secured like it should have been and they fixed it. Every time we have had it fixed it does it again within a couple weeks/month. I did some research and saw a bunch of people are having the same issue with theirs.

The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 45 MPH, the vehicle jerked, with an abnormal sound coming from underneath the vehicle. In addition, the contact stated the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The vehicle was taken to Firestone, where the contact was provided DTC: P0420 (Catalytic converter was fractured and punctured, and a bracket was missing). The vehicle was not repaired. The contact then took the vehicle to the dealer where it was diagnosed and determined that the muffler was punctured and not the catalytic converter. The vehicle was not repaired. The contact then took the vehicle to a Valvoline Center to be diagnosed and DTC: P0420; was retrieved. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that the vehicle was vibrating abnormally while driven with an abnormal rattling sound coming from underneath the vehicle. Upon further investigation, the contact related the failure to Manufacturer's Recall Numbers: N212356540 and N222385510; however, the vehicle was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 102,000.

Engine light came on couple weeks ago. Code is p0420 so I did some research and inspected the exhaust system and found the weld on the support bracket of the exhaust pipes was cracked and wore a hole between the pipe and the bracket. There are others that have the same problem with different year models Chevrolet traverses. Mine is a 2020 Chevrolet traverse LT

The check engine light is illuminated. The Chevy app indicates there is an emission related concern regarding the catalyst system. After inspected, the catalytic converter bracket has a hole or is separating from the exhaust pipes. This causes the vehicle sound very loud during driving. Additionally the vehicle has less power during acceleration. The vehicles performance is poor and the maintenance is accelerated.

Unknown to some, but yesterday Saturday around 12:30 I was inspecting the speaker ports in the rear 3rd row passenger area and I noticed these square tabs that says airbags, also in the very middle of second row the same thing but in the rear I was removing one of the mouldings to see why the speakers were not playing, upon inspection there are no speakers and neither are there any form of side and or rear collision safety devices ( airbags) other than seatbelts. If that truck were in an accident say like a T-Bone, or rear end collision, or side rear impact no one is guaranteed safely making out without adverse affects on their bodies and health. I'm starting to wonder if this traverse was salvaged and or restored. Why are there no safety features in this truck?!!
