Noticed rattling under front hood and exhaust entering the interior of the car. Brought to the dealer and they said there are no recalls on this problem and quoted 4K to replace the CAT and exhaust pipes. There is indeed a tsb document covering Chevy Traverse years 2018-2023 - PIP5681C failed bracket weld on the exhaust pipe causes cracks. This is a dangerous situation with exhaust entering the vehicle. I have 4 children that travel in that vehicle daily! Based on what I have read online, this is an existing problem happening frequently with Chevy Traverses. I would like this repair covered by GM.

I was on the interstate trying to merge into traffic and I floored the gas pedal to get into position with the flow of traffic. Upon pushing the gas pedal to its full position the pedal snapped off and I lost my ability to accelerate. I was lucky enough to be able to pull off to the side of the interstate and into the grass. I placed the Traverse into neutral and came to a stop. The gas pedal snapped just above the tab that sticks out where it connects to the module. Very unsafe that this is even a possibility to have happened. I would not recommend plastic for the gas pedal. Thank God the brake pedal is metal.

My 2020 Chevrolet Traverse is experiencing a SHIFT to PARK issue. When the car is placed into PARK, the electrical system does not recognize it and will not shut off the vehicle. There is a defect with the button trigger that allows the gear shifter to move and it is not being recognized. The quick fix is to press this button around 15 times to reset it. Sometimes this works but when on an incline, it does not. It takes turning the vehicle on and off a few times to have this registered. The estimated cost to replace the gear shifter is around $600 to $900 dollars. Please have this item recalled.
