2020 Chevrolet Traverse Complaint Log

Prematurely damaged exhaust system. Identical to Special Coverage Adjustment N212356540 Front Exhaust Pipe but my dealer and GM says that my VIN it’s not coveted

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.

Broken exhaust pipe brackets

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?!!

Mounting bracket on front exhaust pipe separated from the exhaust pipe while driving.

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.

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.

[XXX] [XXX] [XXX] [XXX] 4/16/2025 General Motors Customer Assistance Center P.O. Box 33170 Detroit, MI 48232-5170 Subject: Power Steering Issue – 2020 Chevy Traverse (VIN: [XXX] ) To Whom It May Concern, I am writing to express my concern and frustration regarding a serious issue with my 2020 Chevrolet Traverse, VIN [XXX] . On [XXX], while driving, the steering wheel suddenly became very stiff, making it extremely difficult to turn right or left. A warning message appeared on the dashboard that read: "Reduced Steering Assist." I immediately took the vehicle to a certified dealership, where it has now been sitting for over two months. Despite multiple follow-ups, I have not been provided with a clear repair date. When I contacted the manufacturer, I was informed that the required part is currently on backorder, but again, no estimated time of resolution has been given. During this extended wait, I have been forced to rent a car to manage my daily responsibilities, and so far I’ve accumulated close to $1,000 in rental expenses. My case number is: [XXX]. I am requesting the following: 1. A clear update regarding the repair status of my vehicle. 2. Urgent assistance in obtaining the necessary replacement part. 3. Reimbursement or compensation for the rental car expenses caused by the extended delay, which has not been my fault. I trust that General Motors values its customers and the reliability of its vehicles, and I hope for a prompt and fair resolution to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle jerked abnormally and stalled. The check engine warning light was illuminated. Additionally, the message "Shift into Neutral, and Start Vehicle" was displayed on the instrument panel. The vehicle was towed to a local dealer; where the fuel injectors were cleaned; however, the failure persisted. The contact stated that while attempting to use the Push-To-Start feature, the vehicle hesitated to start. The vehicle was taken back to the same local dealer where it was diagnosed and determined that the fuel injectors needed to be replaced. The vehicle was taken to a local Pep Boys for a second opinion, where it was diagnosed, and several unknown error codes were retrieved. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 20V639000 (Fuel System, Gasoline); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 140,000.

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.

The contact owns a 2020 Chevrolet Traverse. The contact stated that while his wife was driving at an undisclosed speed, the vehicle inadvertently lost motive power in the middle of the roadway. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the starter. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 105,000. The VIN was not available.

The car displayed a message on the board advising the following: "Steering assist is reduced, drive with care" right after the message popped out my steering wheel locked and I couldn't turn, and move the car to a safe place was very hard, almost had a crash. I was able to park, and turned the engine off. When turned back on the message disappeared and turned on again. Next day, no message, the car was running fine and after 8 miles of drive did the same and it required towing.

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

See GMBulletin #19-NA-206 I am getting the "shift to park" warning which makes it difficult to turn off/safely park my vehicle. I know the NHTSA is aware of this as well as numerous lawsuits in progress against GM for significant safety issues. Will this go to recall status soon?

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.

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.

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 2020 Chevrolet Traverse. The contact stated while starting the vehicle, there was a loud rattling sound coming from the rear end of the vehicle. The vehicle was taken to the dealer where it was diagnosed that the exhaust pipe had failed and needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic and was diagnosed that the exhaust bracket needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the mechanic where the mechanic confirmed that the vehicle was associated with N212356540 (Front Exhaust Pipe) and referred the contact to the dealer for further assistance. The vehicle was not repaired. The vehicle was taken back to the dealer but was not diagnosed or repaired. The manufacturer was made of the failure and a case was opened. The contact was referred to the NHTSA Hotline for assistance. The approximate failure mileage was 112,000.

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.

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

Failed catalytic converter. I have had this part repaired multiple times and there is still a leaking issue. I have receipts from both auto repair shops and the dealership showing that this is an ongoing issue.

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), 5 U.S.C. 552(B)(6)

The Transmission went out at 128k miles, a BRAND NEW GM transmission was replaced at a cost of $6,800 to me as it was not under warranty. Less than 2 months and 2k miles later, the new transmission went out. I just got my car back yesterday with yet another GM transmission and once again it is jerking, so I’m sure another faulty transmission from General Motors

Vehicle would not start. Towed to repair shop. 350A fuse blown that controls ignition system. Pulled starter to inspect for damage. Transmission Flex Plate had 7 broken teeth with a tooth being lodged in the starter housing.

Severe transmission shudder, issues accelerating. Torque converter failure is very common with this vehicle, even with following routine scheduled maintenance. There is no engine or MIL light on and symptoms appeared out of nowhere. Failing to be able to safely accelerate can cause accidents, putting lives and property at risk. Looking information up online will show that this is a very common issue with this model year and transmission.

The transmission on my 2020 Chevrolet Traverse has experienced severe shuddering problems when shifting gears. The vehicle is not old and the integrity of the safety of the vehicle puts myself and my family at risk whenever driving it now. The dealer quotes approximately $8,000 for a fix and a similar search online sees other customers with the same issues. Chevrolet should recall the affected vehicles and not force the consumer to pay out of pocket for the repairs.

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 contact owns a 2020 Chevrolet Traverse. The contact stated while driving 55 MPH, there was an abnormally loud sound coming from the engine. The check engine warning light was illuminated. The vehicle was taken to an unknown dealer, where it was diagnosed and determined that the catalytic converter was leaking and there was a blockage in the catalytic converter. The contact was also informed that coolant was leaking into the engine. The vehicle was not repaired. The contact stated that upon lifting the hood, there was a rodent nest near the engine cover. The contact related the failure to GM Technical Service Bulletin Number: PIP5681C (Exhaust leak, Lean Codes, Rattle Noise, or Catalytic Converter Failure Codes); however, the vehicle was not covered under the TSB. The vehicle was not repaired. The manufacturer was notified of the failure and later informed the contact that the case was closed. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 85,600.

I was driving to work at 0530 on 11/10/24. I was on the highway driving the speed limit. A light came on that read "service ESC". Within 2 minutes of this light coming on, I heard a loud noise and the tail end of my car started to spin out. My power steering went out, my brakes did not work and I hit the guard rail very hard. The "electronic stability control" system in my car, turned off on me with only a minute warning, and almost killed me. My car was totaled and deemed a complete loss. Any advice would be appreciated.

I took my vehicle to the shop for noise while driving. It was diagnosed as a cracked flex pipe. Upon research, the 2019 and 2021 models had recalls for the same issue, but not 2020. I did find a bulletin from gm including all models of traverse stating the cause could be a faulty weld. My vehicle looks the exact same as the bulletin. This is a safety issue as a hole in the exhaust can cause exhaust to backflow into the cabin. I'm very lucky and thankful me and my kids have not yet been medically affected.

The flywheel teeth broke off and became jammed in the starter, which apparently caused a short to the fuse block. The dealership hasn’t commented on exactly what the root cause was though for why that may have happened. I don’t have the original part(s) but the dealer might. I was in the car at the time with my entire family. We were in the middle of driving everyone home from school. The power to the car stayed on but the engine completely died. Given we don’t know what happened with I’m terrified the starter may have tried to engage while driving which would have broken the teeth off. The problem was confirmed by the dealer only in the sense that the parts were broken, but they don’t have root cause. The vehicle was never inspected by insurance as it still fell under the 100k mile certified pre owned warranty. No warning prior to the incident but after there was one brief message that came up saying we needed to check engine system.

On 10/12/24, I received an error code that my charging system needed serviced. I was about an hour from my house when I saw the error. I immediately turned on the voltage display and it said the voltage was 11.8. As I was driving home I had an additional error message that said entering battery saver mode. Luckily, I made it home before I was left stranded on the side of the road in the middle of the night. With only 57,323 miles on my car, I had NO idea it would be the alternator. I took my car to Auto Zone to have the battery tested and they said it was fine. I had my mechanic check on Monday 10/14/24, and it turns out the alternator was indeed bad. S

While taking off after being stop the alclenton the tramssmion slip into gear late and you can notice it while foot on pedel after u take off oil was.change but still the same delership says it comon with this suv

After getting my suv back i been notice that ticking sound while driving over 40 mph can't pin point were it coming from the dealership or anybody cannot locate it it happens with speeds.over 40 not exxeced over 60 mph

2020 traverse was at Chevy dealership for state inspection & emissions test, maintenance service- oil & filter change, rotate tires, check all systems, update system & computer, flush & fill all fluids in car. Chevy certified technician preformed vehicle health inspection, multi point inspection . Car was not picking up acceleration will on a 351 mile trip alone, after stopping I notice the car hood was not on correctly when opened the oil cap was not in place but was on molding, oil had been pouring out leaving engine with no oil, the technician had not replaced cap during service and had no replaced brake fluid, antifreeze coolant, washer fluid and transmission fluid. He had force closed the hood, which could have opened at any time while driving, there was oil pouring from vehicle causes hazardous driving for myself and everyone else on highway. Car has OnStar coverage as well as Chevy safe driver function’s, and alerts on all systems all fluid levels, tire pressure, temperature ext. non of these alerts showed or alerted me putting my safety and the safety of others on the roads in danger. The technician in fact disarmed these systems and alerts when servicing my vehicle. Ciocca Chevrolet dealership in Quakertown pa, caused permanent damage to the engine and power train system, as well as putting myself and others in serious danger. The car was towed by OnStar roadside assist back to dealership where they tried to down play the severity of the damage . I refused to take back the car due to it not being drivable or safe. The service manager agreed to buy out my loan and the car is on lot for sale with tag stating ‘sold as is , no warranty” . Due to the computer system being compromised there is no data showing the service or showing the car being in distress , this issue needs to be know as driving this vehicle with out knowledge of engine damage caused from dealership failure to add all fluids during service puts driver, passenger’s and all others in danger.

I have a 2020 Traverse and it randomly got a hole in the manifold. It was repaired and then not even a year later i have another hole. It makes this god awful loud noise, when we took it to the body shop they said that this is a common problem in these Traverses. We are going to have to pay almost $2,000 on top of what we paid last time to get it repaired, but this time they have to replace the entire thing. I think that this should be looked into and possible reimbursement for people having to replace an entire manifold on their car.

My rear exhaust manifold cracked, was told there should have been have been a recall on them bc they are defective. GM is covering 2019 and 2021 Models, but not 2020 models. I had to replace my alternator at the Chevrolet dealership 6 months ago. In the last month, have had the shift to park message come up on my car and that has something to do with the transmission.

When putting my Traverse in park, the car will intermittently say "shift to park", causing me to have to put it back ion reverse, put it back in park and hope it works. The car will not shut off if it says it's in park, causing you to be stuck in there. Also could cause it to not start if the vehicle thinks it's not in park. To note as well, there is already a recall out for 2018-2019 chevy traverse models, along with others. This needs to be extended to newer models as well.

My 2020 traverse has the exact same issue as the 2019, and 2022 models, both of which have active recalls. I contacted Chevy and their response to me was that there was no recall on my model.

Similar to [XXX] . Exhaust bracket broke, was fixed but stress caused converter to break at engine connection. All other years of this generation are recalled but 2020. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 Chevrolet Traverse. The contact stated that on several occasions while driving at undisclosed speeds and making a left or right turn, the vehicle was not stable and was moving unintendedly. On another occasion, while having maintenance service performed on the vehicle, the mechanic advised the contact that the rear toe links had rotted out due to corrosion and needed to be replaced. The vehicle was not repaired. The vehicle was then taken to a dealer where it was diagnosed and determined that the rear toe links needed to be replaced due to the corrosion. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 44,036.

The contact owns a 2020 Chevrolet Traverse. The contact stated that while the vehicle was parked, after starting the vehicle, the vehicle was making an abnormal sound. There was no warning light illuminated. The vehicle was driven to an independent mechanic, who researched the failure, and informed the contact of an undisclosed NHTSA recall; however, the VIN was not included. The contact was also informed that there was a hole in the exhaust system. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact owns a 2020 Chevrolet Traverse. The contact stated that upon starting the vehicle, there was a loud vibration coming from the vehicle. There were no warning lights illuminated. The contact stated that the failure was related to Special Coverage Adjustment: N212356540 (Front Exhaust Pipe). The vehicle was taken to the local dealer, who diagnosed the failure as a fractured bracket on the muffler. The vehicle was not repaired. The manufacturer confirmed there were no open recalls on the VIN. The failure mileage was approximately 95,000.

The car has started to show a "Shift to Park" message on the dashboard when turning off the car. The car won't shut off until you give it a couple minutes and try again. This seems to be a consistent error with chevrolet models with a few years older and newer getting the 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.

The contact owns a 2020 Chevrolet Traverse. The contact stated that the "Shift to Park" message was displayed on the instrument panel while attempting to park the vehicle. The contact also stated that the ESC (Electronic Stability Control) warning light was displayed while at a complete stop, and an audible chime was heard during the failure. In addition, the START/STOP function failed after removing the foot from the brake pedal while at a stop light. The vehicle shut off without warning as the contact attempted to depress the accelerator pedal. The contact stated that a motorist assisted with pushing the vehicle to the side of the road. The contact called for Roadside Assistance and a Police Officer assisted with jumpstarting the vehicle. The Police Officer then escorted the contact to a nearby gas station where the contact purchased a new battery. Initially after the battery replacement, the contact experienced no failures with the vehicle; however, the shift to park failure had recently returned. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The vehicle was not yet repaired. The failure mileage was approximately 135,000.

The bracket on the front exhaust pipe broke off and created a hole in the exhaust pipe which caused the catalytic converter to become detached from the engine. A recall has already been issued for the previous model year of traverse but the issue is still occurring on this year vehicle.

Car battery drained after it sat unattended for 3 days. A jump-start started the car normally and it functioned normally until turned off. Once turned off, the hazard lights would randomly turn off/on, the door locks would randomly lock/unlock, and the parking lights would randomly come on. Replacing the primary battery had no effect. Outcome: Due to seemingly poor design, a drain pipe passes over the BCM (Body Control Module) and drips water directly into it. The mechanic indicated that this is a known issue to Chevrolet, but I do not see any information in the NHTSA about it. Hefty replacement part/labor cost.
