Cracked flex pipe. Common issue with all traverse models/years. Needs to be addressed and recalled!

The forward exhaust bracket weld broke causing a rattling noise and allowing exhaust fumes into the car which is incredibly dangerous.

Vehicle is current at 101,102 Miles, however, the issue started to occur at 75,350 miles. It is the common issue crack in the exhaust pipe just before the flex exhaust tube due to poor welding of the bracket causing the exhaust system to rattle and leak exhaust into the cabin. The same issue has been addressed under Special Coverage N222385510 for 2021 vehicles, and another one was issued for 2019 Chevrolet Traverse and Buick Enclave vehicles. GM Bulletin PIP5681C describes the issue in detail and acknowledges that the same process was used on their 2018-2022 vehicles, but they are only covering the repair of the 2019s and 2021 vehicles. Exhaust fumes do reach inside the cabin of the vehicle especially on calm mornings that have no breeze. This is a potential carbon monoxide hazard. The is no scrape marks or damage to the undercarriage that would have caused the issue, only the heating and cooling of the exhaust system.

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.

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.

The contact stated that the vehicle sounded like a motorcycle. The contact stated that the check engine warning light was illuminated, and DTC: P0171 was displayed.

The contact had called the dealer to advise that there was a bulletin covering the cracks on the exhaust and the catalytic converter pipes, but was informed that the cracks on the pipes were on the wrong side and that the vehicle was not covered under warranty. The manufacturer was not informed of the failure. The failure mileage was 110,045.

Exhaust started to rattle, now it is a loud clangy exhaust. Clearly a part has separated or there are holes in it. Dealership told me my car has a repair out for that for years 2019, 2021, 2022 and 2023 but NOT my year, 2020.

The car has 45,000 and started burning oil. The car is in brand new condition and well under mileage for an issue of such to be occurring. Took to car dealership where purchased and was told $8,500 fix!

The dealer notified the manufacturer of the failure, but no assistance was provided. The failure mileage was approximately 85,000.

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.

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 LT

Weld on exhaust was faulty the bracket malfunction. The exhaust system has leak and rattle with exhaust noises, causing the converter fail.

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.

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

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.

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

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

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.

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.

The front mounting bracket has separated from the front exhaust pipe. Because of this the exhaust pipe has developed a hole around the bracket, leading to a leak and increased exhaust noise. My check engine light is on constantly and will not be able to pass State mandated emissions testing until repaired. This problem was recalled for the 2018, 2019 and 2021 vehicles, but for some reason not 2020 for the exact issue. The problem has been diagnosed today 2/12/24 by my dealership but they want to charge for a known safety issue. 2021 - GM Special Coverage (N222385510) 2019 - GM Front Exhaust (N212356540)
