2020 Chevrolet Traverse Owner Complaints

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.

While the gears are shifted to park, as soon as the car is turned off, a message pops up advising me to "Shift to Park". The car will already be in park. I have to with jiggle the gear shift or turn the car back on and cycle gears a couple times in order for the car to recognize that it's in park.

My Autostop feature failed to work and did not restart my car on 2 occasions. 1) My kids and I was a stop sign at an intersection and the car would not turn back on. I had my truck towed. The next business day they told me it started on it own. 2) I was dropping my kids off at camp out of town and came to a red light. My truck would not restart. I was in the middle of the street. The police has to push me to safety until the tow truck driver arrived. After towing my truck 100 miles to the dealer near my home it started back up. The next day the dealer mis informed me that it was a programming that was coming up. I had to pay that fee plus diagnostics. When going out to test my truck the dealer experience the same issue. A severity case had to be opened to determine the solution to fix the issue. It took about 4 days. This issue is very concerning as I and my children safety was at risk while driving. I asked about turning the feature off but was told it's a state emissions law to have it on so they could not help me.

The front intermediate exhaust pipe mounting bracket weld fractured at the engine manifold, causing the exhaust pipe to break completely loose. We can now actively smell raw exhaust fumes inside the passenger cabin while operating the vehicle, creating an immediate safety hazard for carbon monoxide poisoning and driver disorientation. Additionally, the heavy steel exhaust system is completely unsupported at the front, creating an imminent risk of the pipe falling and dragging on the roadway at highway speeds, which could cause a catastrophic crash. The vehicle began getting progressively louder during cold weather between late 2025 and early 2026. A certified Chevrolet dealership technician officially inspected the vehicle, filmed an inspection video confirming this exact structural failure, and attempted to submit it for warranty coverage. GM Corporate denied the claim solely because my VIN is excluded from Special Coverage N212356540, despite the vehicle suffering from the identical manufacturing defect described in the bulletin. I possess the official dealer repair receipt and the technician's inspection video as proof.

I am filing a complaint regarding a persistent safety defect widely known as the "Shift to Park" issue. For over a year, my 2020 Chevrolet Traverse, VIN [XXX] has repeatedly displayed a "Shift to Park" warning message on the instrument cluster when the vehicle is placed in Park and the engine shutoff button is pressed. This occurs multiple times weekly. Despite the vehicle physically being in Park, the internal shifter sensor fails to recognize the gear position. This defect prevents the vehicle from shutting down properly, leaving the electrical system active and causing severe battery drain. Furthermore, because the vehicle does not recognize it is in Park, it creates a roll away risk if the driver exits assuming the vehicle is fully secured. General Motors is aware of this widespread component failure across this vehicle platform but refuses to issue a safety recall or cover the repair costs out of warranty. This is a systemic manufacturing defect that presents a clear financial and safety hazard to consumers. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 new and should never have needed a brand new transmission, torque converter replacement and still having shudder problems. These vehicles need to be recalled for their power train.

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.

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 it's out of gas??? Not what I would classify as safe! General Motors should be taking steps to rectify this problem immediately but since they have not had "enough" complaints to warrant investigating further they are sitting idly by! HELP!

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.

I have 37,000 miles and have taken it to a Chevrolet dealer for all suggested routine maintenance. It started shuddering so I took in to dealer. They said known issue and may need a new torque converter which would cost approximately $8500. They suggested I try changing the transmission fluid even though suggested at 45,000 miles. They said to drive 200 miles and see if it goes away. I haven't yet put 200 miles but am very concerned there is a bigger issue with the Traverses out there and afraid this is a band-aid and feel a recall may be inevitable. Just wanted to share with you.
