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.

I have an exhaust issue with my 2018 Traverse that a Chevrolet/gm refuses to cover. I am getting check engine light that points to a leaking exhaust. The cause for these concerns could be a broken or poor weld with lack of penetration on the bank 2 exhaust flex pipe bracket. It's a known gm issue on the 2018, 2019, 2020, 2021, 2022 models. Gm has a safety bulletin pip5681 and pip5681a for this issue. N222385510 is the number for the 2021 recall. The dealership said it will not cover the repair because my VIN has no associated recall. Gm allowed the repair of the 2020 under the same recall number. This should be covered under exhaust warranty.

Metal found in transmission and new transmission needed. 2018 chevy Traverse.

I am filing this complaint due to a recurring exhaust leak in the front exhaust pipe of my 2023 Chevrolet Traverse, which poses a potential safety hazard. During the vehicle’s bumper-to-bumper warranty period, freedom Chevrolet in san antonio replaced a leaking front exhaust pipe (receipt attached), a known issue covered by a technical service bulletin (TSB) for earlier model years (2018–2022) but not for the 2023 Traverse. Less than two years later, with the vehicle now at approximately 84,000 miles, the front exhaust pipe has failed again, exhibiting the same leak issue. This recurring defect is concerning because exhaust leaks can allow carbon monoxide and other harmful gases to enter the vehicle cabin, posing a risk of poisoning or impaired driver awareness, especially during extended operation. Additionally, the issue may contribute to environmental hazards due to improper emissions control. Despite my requests for assistance from freedom Chevrolet and gm customer care, I have not received a satisfactory resolution, and the repair cost falls on me as the vehicle is out of warranty. I am aware of complaints and tsbs documenting similar exhaust leak issues in Chevrolet Traverse models from 2018–2022, including a recall for the 2019 model year (NHTSA n222385510), suggesting a systemic issue that may extend to the 2023 model. The lack of a TSB or recall for the 2023 Traverse leaves owners like myself vulnerable to repeated failures and safety risks.

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.

Owned brand new vehicle for 48 hours. Fuel injector failure on cylinder 4 at 120 miles on the dash. Check engine light was on. Vehicle is currently at dealership. Engine unreliable/unsafe. Dealer confirmed. Dealer stated up to 10 days waiting on parts. Unknown if further damage has been caused. Wife states vehicle had a rough idle. Diag code p0300, p050d.

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.

I was driving along the highway way at 60-65 mph when suddenly service traction control came on and vehicle started jerking and slowing down. As I tried to accelerate it continued to jerk and then just shut off completely. I hit the guard rail/ jersey wall on the drivers side because I had no control of the vehicle due to the vehicle shutting down. Upon taking it to the dealer after getting it home they stated it could be the junction box which is a known issue but they don’t see anything wrong with it and can’t duplicate the problem. I’ve contacted various mechanics and get that it’s an electrical issue that Chevrolet is aware of but refuses to place a recall for it. I could have gotten seriously injured if not killed by this problem and safety issue.

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 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.

Special coverage n242445280 front exhaust pipe mounting bracket breaks creating a hole in the exhaust pipe. Coverage referrers to left side pipe, but bracket connects to both left and right side pipe and when breaks can brake on both pipes at the bracket location creating an exhaust hole in either / both pipes. Currently gm is only replacing the left side but needs to replace both.

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.

Transmission issues vehicle shakes while accelerating.

The vehicle was taken to a dealer where it was diagnosed; however, the cause of the failure was unknown. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was 35,010. The VIN was invalid.

The power train on 2019 chevy Traverses are horrible! there was a recall back in 2023 that caused me to get a replacement transmission. It hasn’t even been a full 2 years and the transmission is out again! even with recent safety issues for the emissions purge valve and transmission defects on these cars, no one has initiated another recall for the power train system. This is frustrating, inconveniencing, and infuriating. I hope gm makes this right!.

Gm has a TSB # n212356540 for one exhaust pipe. Bracket broken a causes hole in pipe. Weld was bad. Mine was bad on both pipes and only one covered by gm, this led to catalytic converter cracking and flex pipe leaking. I had to pay to have repaired. This second pipe and catalytic converter were not covered.

Multiple issues have occurred with this vehicle. I have had major unsafe issues while driving while on the freeway and streets where my vehicle reads traction control off and engine power reduced which leads my vehicle to lose all power and shut down being stranded and almost hit multiple times while by myself and while my husband and children are present. I believe I am the second or third owner of this vehicle and I was never given any information about any recalls.

Car will not accelerate fast up hills.

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.

Oil consumption issues.

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 contact owns a 2024 Chevrolet Traverse. The contact noticed liquid underneath the vehicle where the radiator system was located. The vehicle was taken to the dealer who diagnosed that the radiator and coolant system had failed. The radiator and coolant were replaced. After having the repair completed, the contact had the vehicle inspected for the dmv admission test and the vehicle was reported as failed. The vehicle was returned to the dealer who could not find the cause of the failed test. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 18,000.

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.
