July 2025 the transmission started stuttering. Took to an outside transmission shop, report showed torch converter failure.

For the last year or so my car keeps making this really loud noise and it gets worse within hours/days. We have had it in 3 maybe even 4 different shops to have an exhaust fixed. One shop said that a part of it was never secured like it should have been and they fixed it. Every time we have had it fixed it does it again within a couple weeks/month. I did some research and saw a bunch of people are having the same issue with theirs.

- Shelbyville, KY, USA

The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 45 MPH, the vehicle jerked, with an abnormal sound coming from underneath the vehicle. In addition, the contact stated the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The vehicle was taken to Firestone, where the contact was provided DTC: P0420 (Catalytic converter was fractured and punctured, and a bracket was missing). The vehicle was not repaired. The contact then took the vehicle to the dealer where it was diagnosed and determined that the muffler was punctured and not the catalytic converter. The vehicle was not repaired. The contact then took the vehicle to a Valvoline Center to be diagnosed and DTC: P0420; was retrieved. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that the vehicle was vibrating abnormally while driven with an abnormal rattling sound coming from underneath the vehicle. Upon further investigation, the contact related the failure to Manufacturer's Recall Numbers: N212356540 and N222385510; however, the vehicle was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 102,000.

Engine light came on couple weeks ago. Code is p0420 so I did some research and inspected the exhaust system and found the weld on the support bracket of the exhaust pipes was cracked and wore a hole between the pipe and the bracket. There are others that have the same problem with different year models Chevrolet traverses. Mine is a 2020 Chevrolet traverse

The check engine light is illuminated. The Chevy app indicates there is an emission related concern regarding the catalyst system. After inspected, the catalytic converter bracket has a hole or is separating from the exhaust pipes. This causes the vehicle sound very loud during driving. Additionally the vehicle has less power during acceleration. The vehicles performance is poor and the maintenance is accelerated.

Unknown to some, but yesterday Saturday around 12:30 I was inspecting the speaker ports in the rear 3rd row passenger area and I noticed these square tabs that says airbags, also in the very middle of second row the same thing but in the rear I was removing one of the mouldings to see why the speakers were not playing, upon inspection there are no speakers and neither are there any form of side and or rear collision safety devices ( airbags) other than seatbelts. If that truck were in an accident say like a T-Bone, or rear end collision, or side rear impact no one is guaranteed safely making out without adverse affects on their bodies and health. I'm starting to wonder if this traverse was salvaged and or restored. Why are there no safety features in this truck?!!

Front exhaust pipe broken causing check engine light and vehicle to sound rough. It is an emissions issue. This has been confirmed with a dealership. The issue started around middle of March 2025 when check engine light came on.

- Piedmont, OK, USA

Had noticed a rattle every time when I start the vehicle.I got under and had located a broken front exhaust hanger. A few week later I noticed a different sound coming from under the vehicle. I go back to the under side and locked the exhaust flex pipe has now ripped at the front exhaust bracket. Mine being a 2020 isn't coved by the 2019 or the 2021 special coverage. Chevrolet needs to fix this issue.

The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 25 MPH, the check engine warning light illuminated. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed and determined that the catalytic convertor had failed needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure, and the contact was informed that there were no recalls associated with the VIN. The approximate failure mileage was 58,000.

- Madison, AL, USA

Car started making a -??pinging-?? noise and gradually got worse over time. Finally today, it-??s really bad so I crawl under and look to notice not one but TWO holes in the exhaust pipe. I noticed several recalls on other models with the same issue but not this year.

- Russellville , AR, USA

The exahust leaks and has noise just like all the other Traverse that have the recall, this also needs the same recall

Vehicle developed a large hole in the exhaust pipe going to front converter. Identical failure which is noted in an April 30,2023 bulletin which specifically narrowed defects down to the 2019 Chevy Traverse. ( Special Coverage# N212356540). Dealership did repair defective exhaust section although my warranty coverage refused to cover defect. Significant safety hazard to state the least anytime a section of any exhaust component begins to deteriorate and come apart on welded sections of pipe. My vehicle has approximately 59000 miles of use and I simply cannot understand why GM refuses to reimburse my out of pocket costs related to this defect.

A few weeks ago, I started noticing a purring, kind of sound coming from my vehicle when I would turn it on. I took it in to Chevy and they said there was a leak or a hole in the exhaust that they needed to be replaced for over $1600 and that wasn-??t covered through warranty that it was normal wear and tear. My vehicle has 53,000 miles. They said that it-??s common for a vehicle of over five years to have these kinds of issues. And that it wasn-??t covered through my warranty. Which expires in April

- Los Banos , CA, USA

Noise from under hood, took vehicle to dealer. Dealers inspection identified cracked exhaust PIPES before catalytic converter. Exhaust fumes get into car cabin causing health concerns not to mention a life threatening situation for the occupants. Vehicle was under 70k miles. Seems to be an emission issue/faulty workmanship with failure in QC in weld inspection causing harm to owners

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.

Front Flex pipe broken after failed weld. Issue is known by GM/Chevorlet and has been corrected on all years Except for the 2020 model year. Not sure why 2020 models were left out because they have the same condition.

- Fort Myers, FL, USA

Purchased the 2020 traverse on [XXX] from Basswood in Ft. Payne Alabama. Under the guise of the salesman I was assured that the vehicle was in great shape, with no issues at all, and a very clean Carfax. Well I'm new to purchasing a car via financing with a co-signer in which he was assured the vehicle was in great shape. Well unbeknownst to us my household the car was nothing of the sort. Within a few days the Start/Stop malfunctioned to the point it would not restart 98% of the time without sounding like a Demo Saw, it's a dangerous problem and there's times we smelled fuel once we were able to restart the vehicle. The front right wheel assembly looks as if it were on fire and if that's brake dust and it has a grinding whomp whomp sound when in motion, that's really not good no wonder it's hard to stop at times. The front end sounds like drums when going over bumps, speed bumps, road imperfections etc.. on morning start-up there's an absurd amount of exhaust coming into the cabin area, the codes [P3055 and P3056] are registered from the computer of vehicle. Now the smell of fuel is blowing through all vents whenever the defrost is running or all vents are used front and rear, with the truck in motion. It was so bad today that my entire family had to pull over to a gas station and get fresh air our eyes were burning and my [XXX] son nose started to bleed., so that's two parents and 6 children scrambling for safety. This is our only reliable vehicle other than an old 99 suburban that is hardly even road worthy anymore. I spoke with several people that have purchased vehicles and all agreed that the salesman and mostly the sales managers knew that the vehicle came from an auction and was never serviced nor inspected at the basswood dealership, which equates to them actively concealing major effects and problems with the vehicle in question. Just to make a one time commission on a fraudulent deal! They didn't provide any inspection papers to me! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

The exhaust bracket on the front broke, and caused my catalytic converter to crack and have an exhaust leak. I-??ve talked to different exhaust places and said it is common in the 2020 traverses. The car is running rough.
