2020 CHEVROLET TRAVERSE Unknown Or Other Problems

The vehicle just suddendenly shuts down when driven on the freeway, according to Tillery Chevrolet GMC the engine cracked and needed to replaced for total of $17,291.94

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.

Burning oil. There is something wrong. I took it to the dealership i still have warranty i really think this needs to be looked into.

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.

Exhaust and catalytic converters keep breaking off causing loud noise and check engine light to stay on

Catalyst converter bracket on the front of my exhaust is broken causing loud noise and the check engine light to remain on. This should be in connection with specialized coverage program N212356540

Leaking exhaust noise at start up began around 7/14/25. Noise became louder over the following week. Check engine light came on morning of 7/25. Immediately took it to local GM dealership for inspection. Dealership first said it was a cracked front exhaust pipe but then they also determined that the check engine light was from the catalytic converter. Dealership said both the exhaust pipe and catalytic converter require replacement. Through research, we discovered there are already recalls and special coverage for the same issue on the 2019, 2021 and 2022 year models of this vehicle.

Exhaust system developed a hole due to poor weld, Bulletin # PIP5681A. Updated 10-5-20 to include 2020 Traverse. Fumes are getting into the cabin.

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.

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

Broken exhaust pipe brackets

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.

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.

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.

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

Special coverage for 2019 and 2021 model traverses for front exhaust pipe - but not for 2020 models and it’s the exact same issue.

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.

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.

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.

The vehicle is in park and then turned off but I get the "shift to park" notice that is persistent. While it's doing this, the dash display clearly shows a "P" for park so it is in the correct gear but not recognizing it.

The backup camera in my Chevy Traverse stopped working a few months after purchasing the vehicle new. Whenever the car is put in reverse a black screen appears with an exclamation point inside of a triangle. This seems to be an extremely common issue with 2020 Chevy Traverses as there is numerous postings on online message boards about the same issue of the backup camera dying shortly after purchase with no resolution. Today while backing up I struck another vehicle that was also backing up that I would have been able to see if the backup camera was working. It also appeared the audible object warning did not activate. Luckily there was only minimal damage to the vehicles. It is extremely difficult to backup the vehicle without the backup camera due to the length of the vehicle as well as blind spots in the rear windows. This issue seems to be ongoing with this model and is costing consumers significant amounts of money and time in shop because Chevy does not seem to be able to resolve the issue with their Traverse backup cameras.

According to General Motors, the new GM Special Coverage (N222385510) is only applicable the 2021 model year of the Chevy Traverse. The condition described includes the separation of the front mounting bracket from the front exhaust pipe. This happened to prior year models and are covered under a recall too. All years I searched as well as my mechanic. My vehicle is a 2020 and the same issue is present but has not been covered under a recall.

Rear view camera does not work most of the time. This in turn shuts down Surround Vision system. Cannot see behind the vehicle when this occurs. Has been an issue since new, fix was attempted by dealer several times but has never been resolved.

Exhaust System Flex pipe failed causing additional exhaust noise due to exhaust discharge,before catalitic converters this caused MIL light fault P0420 and potential exhaust leakage under passenger area of vehicle. Vehicle issue has been confirmed several times by dealer and quoted $1800 repair

the exhaust broke, sounded like I was a race car driver. Muffle making loud noise while parking and driving

Alternator failing and needing to be replaced on a 2020 Chevy Traverse with only 33,000 miles. Seems to be a common issue with several Traverse and it's a costly repair as it's past warranty.

I own a 2020 Chevrolet Traverse. At the time of the incident, I was driving at 55 mph and heard a very loud and unusual sound. The vehicle then began to uncontrollably shake so I pulled over to the right shoulder. A truck driver pulled over with me as he thought it was something in his truck that had malfunctioned due to the intensity of the sound that it produced. At the rear right wheel of my vehicle, the metal rim was broken vertically causing the rim to separate into two parts. The tire is completely intact. Thank god, the outermost part of the rim that holds the nuts did not break and stayed completely whole and solid letting me pull off to the right shoulder. To put it into perspective, the wheel was left in three different parts. The first part was the tire. The second part was the cylindrical shaped metal rim that stayed inside the tire. The third part, being the outermost part of the metal rim, can be envisioned as a simple cap. There were not any warning lights that became illuminated on my dash. My vehicle has not been previously repaired or diagnosed by any independent mechanic or dealer. The wheel, tire, and rim are the original fabricated parts that came with my vehicle.

The exhaust broke under 2020 traverse with 41365 miles allowing fumes to come up through the floor into cabin. You have a repair notice # N212356540 for this problem on 2019 traverse and # N222385510 on the 2021 traverse ...dealer says my 2020 is not covered. Please let me know why.

Since Oct 2022, my backup camera has been intermittently working (it doesn’t work most of the time). I have taken it to the dealership and they replaced the coaxial cable in February 2023 but the problem keeps persisting. I have taken it to the dealership a total of 4 separate incidents and the problem has been reproduced and confirmed by the service tech each time. This last time, I was informed there was three codes showing up so they were not sure what the problem was. I was told that even though the service representative saw that the camera wasn’t working when the technician came it was working so they couldn’t do anything. I was told to bring the vehicle back when it did it again. It has constantly not been working properly since I brought it home. When the camera doesn’t work a a red triangle and a circle with a line through it displays on the screen. I feel as this is putting my safety as well as others safety at risk every time it doesn’t function properly. The inability to use my back up camera reduces my ability to see behind the vehicle. This increases the risk of a crash, injury or property damage when the vehicle is backing up. I have not been involved in any incidents but there have been a few near misses.

Months ago I was driving, my 2020 traverse I hit the brakes and I heard a weird grinding noise & my car started wobbling, I figured I needed my brakes pads changed, I took it to Waldorf Chevy they looked at the brakes and told me everything was good I didn’t need pads and everything was ok, they said sometimes the pads get dust on them causing them to squeak, and wobble, i had the front pads replace at a local shop they also looked at the back brakes and said the back pads were good, sometime later I was heading to work I stopped at a gas station and the car wouldn’t start. On the Chevy app it said my antilock brake system and stability control needs serviced which was weird it gave no warning I had it diagnosed the mechanic said the engine seized I towed it to another shop they said the same thing I towed it to Chevy they insisted it was the battery I told them it was the engine, they later said the engine seized but not before charging me $500 for a diagnostic, $371 battery plate. I got oil changes regularly and often did preventive maintenance.

THIS STARTED AROUND MAY 2020... I WAS AT ABOUT 2K MILES IN. I WAS TOLD IT WAS DUE TO WEATHER. AND THAT THEY HAD OTHER CHEVY WITH SAME ISSUE- "SO IT'S NORMAL". I BOUGHT THE 2020 CHEVY TRAVERSE BRAND NEW RIGHT OFF LOT. AFTER WE PACKED UP AND VISITED FAMILY I NOTICED IT HAD SOUNDS. THE SOUNDS WERE LIKE WHINING NOISES JUST LOUD AND SERIOUSLY OBNOXIOUS. IT ONLY HAPPENED WE WERE TURNING VEHICLE AT FIRST. SO WE GET HOME AND IT STARTED BEING LOUDER. I THEN NOTICED AS I WAS DRIVING AND AFTER I SLOWED DOWN TO LIKE 20 HEADING FOR A STOP SIGN THE CAR SUDDENLY HAS THIS BURST OF ENERGY AND SPEEDS UP TO LIKE 33 CAUSING ME TO HIT BREAKS. I TOLD MY HUSBAND AND HE WAS LIKE I DON'T KNOW MAYBE IT IS EXPUNGING GAS. AFTER I SLOW DOWN? ISN'T THAT DANGEROUS. I IGNORED IT BUT IT CONTINUES EVER SO OFTEN AND THIS IS ON REGULAR STREETS -SPEED LIMIT IS 35. THEN THE WHINING NOISE FROM WHEEL HAD ME TERRIFIED. SO WE WENT TO DEALER. THAT WAS COMICAL. DUDE WAS LIKE "IT'S A CHARACTERISTICS OF THE CAR". I'M LIKE WHAT? WHY WOULD THEY MAKE A CAR WITH AN ANNOYING SOUND - ITS DISTRACTING. I DON'T WANT TO DIE BECAUSE OF MY WHEEL. I READ ONLINE OTHER PEOPLE HAD PROBLEMS SO WE WENT TO ANOTHER DEALER AND ANOTHER. THE GUY AT LAST DEALER WAS LIKE THIS IS NOT NORMAL. THEY CREATED CARFAX REPORT AND SWITCHED PART OUT. I COULD GO ON. SO THAT LOUD NOISE NEVER WENT AWAY- AT FIRST IT WAS LOW AND NOW LOUDER. I CALLED CHEVY AGAIN AND THEY ARE LIKE A DEALER HAS TO ACCESS SITUATION AND CALL US. THIS IS NOT SAFE. ALSO THE OTHER PROBLEMS ARE SEATBELT LOCKS. THE MIDDLE SEAT DESIGN IS TERRIBLE. MY DAUGHTER WAS SITTING THERE WHEN IT WENT BACK IN BETWEEN SEAT AND LOCKED IT WOULDN'T LET UP NO MATTER WHAT. HAD TO TAKE SEAT APART TO FIX SEAT BELT. MY SEAT IN FRONT LOCKS AND ITS RELENTLESS. SO UNCOMFORTABLE AND IT CHOKES ME BECAUSE I'M SHORT. TERRIBLE DESIGN BECAUSE IT CAN'T ADJUST LIKE THE GM VERSION. I HAVE VIDEO PROOF/RECEIPTS.
