2020 Chevrolet Traverse Complaints

I own a 2020 Chevy Traverse with currently 16,000 miles. I am currently dealing with a know shudder issue that has returned. I have already taken the vehicle under warranty to the dealership where the transmission was replaced on 6/29/2022 at 4919 miles for “catastrophic failure” where the fluids were dark, burnt, and several burnt up clutches. Then the torque converter was replaced separately on 9/20/2022 at 8106 miles for engine shudder. Took the vehicle again in on 7/21/26 for shudder returning at 16,450k miles where diagnostic shows dark, burnt fluid, with metal debri. Repair recommendations are to flush again and if not fixed to again replace the torque converter. There are no open recalls on my vehicle when there should. There is the most recent bulletin, Bulletin No.: 23-NA-072 dated May 2023 that covers the 2020 Chevy Traverse for TCC Shudder: (Typically seen on 4th-5th Upshift as ISS Oscillation) which is referenced on my last car diagnostic report. This car is basically brand...

The contact owns a 2020 Chevrolet Traverse. The contact stated that while parking the vehicle, the gear shifter was shifted into park(P); however, the “Shift to Park” message was displayed. The contact shifted the gear shifter back and forth and then shifted into park(P) before the proper gear was recognized. The vehicle was taken to the dealer, who replaced the gear shifter. The manufacturer was made aware of the failure. The failure mileage was 26,818.

There is a well known exhaust issue with the catalytic converter and the separating manifold and no recall has been issue yet. It causes the vehicle to lose pressure and shuts off in the middle of traffic. The seat belt secure locks are malfunctioning and could cause loss of life in the event of an accident.

GM published bulletin PIP5681A on 10/05/20 regarding defective welds on the exhaust brackets near the catalytic converter. I had the same exact weld failure and GM is not honoring the warranty coverage, even though their bulletin said that all 2020 Traverse SUVs were included.

The welds that hold the catalytic converter and exhaust pipe together have pinhole leaks. The hose that connects to the exhaust system is also failing. This has been confirmed by the Chevy dealership we took it too. No warning lights were triggered. We heard a rattling noise after having a prior hose replaced. One week later we were back at the same dealership. At this appointment they discovered the pinhole leaks and confirmed there are pinhole leaks while revving the engine to 1,000 RPMs. We requested GM pay to fix the issue and they have refused. Our safety is at risk because no sensors were triggered and we could smell exhaust fumes in the vehicle while using the air conditioning. This is not the first issue we had with this vehicle. Prior to this the whole car died while my wife was driving it with our 2 kids in the car with her. She had no steering or braking.
