2020 Chevrolet Traverse

The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 35 MPH, the vehicle stalled. The contact stated that the service engine warning light was illuminated. The contact took the vehicle to the local dealer however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The contact had experienced the failure several times. The manufacturer had not been informed of the failure. The failure mileage was unknown.

I was operating my vehicle at 70 MPH on the freeway, when I took my foot off the accelerater pedal to exit I could feel a pop under my feet and the engine started to make a lot more noise. I lost engine power and had to coast/idle to the nearest gas station. I went under the car and discovered a hole in my exhaust where there used to be a bracket to mount the exhaust pipes to yhe undercarriage. I went on a chevy Traverse Forum to discover this is a common problem. I believe it is unsafe to operate the vehicle with an exhaust leak that also creates loss of engine power and eventually leads to engine damage.

Muffler pipes are rubbing on the metal that was used to hold the muffler pipes from dragging. There is nothing to stop this from happening. If it’s Rubbing holes in the muffler then it’s allowing the fumes into the ozone layer and also wasting gas and messing the engine up m, causing the engine to read wrong. This is not Normal wear and tear this is a manufactured default that should not be my responsibility bc it wasn’t secured correctly.

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.

I was driving down the street and my car started to randomly jerk. When I pushed the gas the car got slower. Once in a safe place I pulled over and sat there for a few minutes. When I accelerated again the car had a sound like the car was speeding up, but there was no speed. It drifted. So I crossed the traffic light and pulled over again. I turned the car off. I waited for about 5 minutes, turned the car on and that's when the engine light came on. I had to drive slower to make it home. Once I made it home I put the car in Reverse and noticed that my back up camera was not working as well. I am so frustrated.
