2020 Chevrolet Traverse other reported problems

UNKNOWN OR OTHER

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!

2020 Chevrolet Traverse vehicles may experience a loud, rumbling exhaust leak caused by a failing front exhaust pipe bracket weld, frequently noted in complaints. While special coverage exists for other model years, 2020 owners are experiencing similar issues, with some reports suggesting it may not be covered under the same official, extended recall. My vehicle is experiencing the same issues that the 2019, 2021, and 2022 model are experiencing why is my 2020 and other owners of a 2020 year skipped to be covered for this identical problem.

The backup camera system on my 2020 Chevrolet Traverse fails repeatedly and intermittently. When shifting into reverse, the camera frequently displays a black screen, a crossed-out camera icon, or an error message indicating the camera is unavailable. I have brought the vehicle to a Chevrolet dealership multiple times for this issue. The dealer has replaced the rear/front camera twice and replaced a corroded cable, but the problem continues to occur. The repairs have not permanently resolved the issue. The failure happens unpredictably and makes it unsafe to reverse the vehicle, especially around pedestrians, children, or obstacles. This vehicle is equipped with a federally required backup camera, and its repeated failure presents a safety concern. The problem appears to be a recurring defect rather than normal wear, as many other Chevrolet Traverse owners have reported similar issues online. I am concerned this may indicate a broader defect affecting this model year.

Leaking exhaust noise at start up began around 9/22/25. Noise became louder over the following week. Check engine light came on morning of 9/24/25. Immediately took it to local GM dealership for inspection. Dealership first said it was a cracked front exhaust pipe at the bracket and then they called back and said rear pipe at the bracket was broken also the whole system needed to be replaced because the brackets were not separate but welded directly to the pipe. The estimate was over $1300. Dealership then said the error coded was probably because of the exhaust pipe and catalytic converter and that they require replacement. I discovered there are already recalls and special coverage for the same issue on the 2019, 2021 and 2022 year models of this vehicle. I contacted GM and they acknowledged the problem in other model years before and after but said there isn't enough complaints for this model year. This is a known problem and design flaw. This needs to be addressed by GM immediately. NONE of the welds have held on any parts of the exhaust system or the catalytic converter.

Due to exhaust bracket failure where converter with muffler and side down pipe needs replaced. This was diagnosed at the Chevy dealer and appointment for repair is made. The exhaust suddenly became very loud so I took it to the dealership. There were no messages or warning lamps.

When I put my car in park and turn it off I get an error message that I need to "Shift to Park". It shows in the dash that it is in park but my radio, and lights stay on. I have to restart my car and put it in park, reverse, or neutral and try to put it in park again. I takes several try's to make the error message go away.

Rattling noise when starting vehicle started occurring a year ago. Dealership diagnosed a broken bracket weld that holds the exhaust pipes in place. Dealership cut off bracket. A year later there is a hole in one of the exhaust pipes because of the broken bracket and a check engine light comes on. There is a recall for the 2018-2023 Traverse models EXCEPT the 2020 year for the exact same issue. Why is every other covered but not the 2020? Why do I have to pay for a known GM issue that causes a hole in the exhaust pipes from their crappy bracket welds? This is an emissions issue yet we are being denied by our dealership.

I own two 2020 Chevrolete Traverse. I am currently dealing with my second one that has an exhaust leak at the forward joining exhaust bracket. This is a poor design for a hanging exhaust and is a known issue for the 2019 and 2021 models, but not the 2020. These other years have a special coverage to repair the forward exhaust but not the 2020 traverse because there have not been enough reports on it. I already paid out of pocket to repair my other 2020 traverse with this known problem and I refuse to do it again because of a design flaw. This needs to be addressed by Chevrolete immediately.

The car started making a weird sound, thought it was transmission because it only happened when i accelerated. Took it to the dealership abd they wanted to charge me $1000 plus labor. I said no,this is a deffect and it should be covefed by the warranty, the said it wasnt. So i took it to a exhaust shop and they welded it but it cracked again and after a while, it actually tore a little hole into the muffler. So i let it be, maybe make the repair when i had the money to spare. But money being the issue, i went to a muffler shop and had it re soldered, it worked for a while, but now its back. It sucks thay gm put out the recall for specific vehicles knowing that it is a very general thing. Plase help me.

It just started showing a error message to SHIFT TO PARK when the car is already in Park. I took it to Register Chevrolet in Brooksville, Fl on May 14, 2025 and they said it needed a whole new shifter that it is defective. This is a major safety issue. I can currently still turn the car off but alarms start going off and was told I may not be able to turn the vehicle off or not lock the doors and could drain the battery. This is absolutely ridiculous there has not been a recall on the safety issue. I have seen that hundreds of others have had the same issue and there has been class action lawsuits. The dealership said it would be around $800 to fix the defective part. Also, I purchased the vehicle in Ohio but moved to Florida in Sep.2021.

The car violently shudders when it attempts to shift from 1st to 2nd gear. This happens every time I drive the car and I'm unsure what's wrong with it. I am unable to accelerate quickly when attempting to drive on the highway or when making a turn and am afraid of being hit because it won't accelerate shift gears as it should. I've taken it to the Chevy dealership twice, and the issue was not addressed as requested so, I researched online and learned that this is a common issue in Chevy Traverses, and it doesn't seem to be fixed, even after dealership intervention. I'm wondering if this is why the dealership is hesitant to address the issue. I am concerned for my family's safety.

The vehicle start stop feature is malfunctioning (I have a video) .When stopping or coming to a stop after driving through the city, at random times sometimes back to back when being stopped it goes down to 1 rpm then the auto stop feature kicks on and when it's time to depress the break to move again it malfunctions then sounds like a circular saw slicing through metal. At times you have put car in park hit engine ignition button to make it stop then wait a few seconds then start it back up. There's also a smell of strong fuel vapors coming in through the vents including defrost. Navigation stopped working ( turn by turn ) feature, also sounds as if the front end is knocking around going over speed bumps, the front right wheel has an odd rub sound that increases when accelerating. The gas also with a full tank depletes nearly within a day, and ait being a V6 should not guzzle $50 in fuel of 87 grade petrol. This thing is a rolling safety hazard. I have a wife and 6 children I transport daily. If something happens and we are injured I will sue your entire company General Motors.

My backup camera only works about 3% of the time. If the temp are too cold or too hot then the screen goes black with a red triangle. Frequently, this occurs when I'm in the process of backing up and I lose all visibility. I almost struck a pedestrian this morning. I've already had the cable repaired at the dealership once but it immediately began not working about 2 weeks later. I had taken it back to the dealership but they were unable to repair because the representative could not reproduce the error when he attempted to back up. I have videos of what is occurring.
