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 then the torque converter was replaced separately on 9/20/2022 at 8106 miles for engine shudder. This vehicle is practically brand new. I reached out to GM with no help other than to pay to have it diagnosed again at the dealership. 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) This car is brand new and should never have needed a brand new transmission, torque converter replacement and still having the exact same problems as before.

Getting error message on and off last several weeks - "Shift into park" which does not allow the ignition to be turned off!! The only way to resolve this issue is to jiggle the gear shift or restart the car, changing gears and trying again. Sometimes it works on the second or third try! Frustrating!!! What is it doing to the shift assembly? Have called local dealer they will diagnose and repair at my cost! In the neighborhood of $250.00 for diagnostic, which will be applied to the total repair costs. No idea what that bill will be. General Motors just advises if it needs repair save my receipts in the event of recall for reimbursement. The car only has 21,600 miles!! I have seen other complaints on line and there are videos on You Tube on how to repair this issue, obviously I'm not the only one this is happening to. The gear shift boot and console have to be removed to repair. If the above actions do not work, how do you shut the ignition off??? Just let the car run until...

This is a know issue on 2021 models. The exhaust bracket is breaking away from the muffler/catalytic converter. The weld is breaking causing the exhaust to break away and both pipes must be replaced resulting in a 1500 repair. Why if it bad in later years is there no maintenance bulletin or mandatory fix for the 2020 models? It was repaired and fixed by McClusky Chevrolet in Cincinnati OH.

Flex pipe for exhaust is broken at 61000 miles rattles and makes noise upon start up and acceleration.doesnt make sense repairs for model years before and after 2020 are being repaired for free

While driving the stereo went off, the ac, the car stopped in middle of the road and I lost all electrical. I tried turning back on and the emergency brake light was on and the dash said "Steering Assist is Reduced, Drive with Care.” I was able to put it in neutral and get it out of the way. Battery is good Fuses were all checked 350 replaced Car isn’t starting or Turing over, but some of the lights have turned on.
