2020 Chevrolet Traverse

General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, Cadillac XT6, Chevrolet Traverse, and GMC Acadia vehicles. The fuel pump's jet nozzle may have a plastic burr remaining from the manufacturing process, possibly causing a blocked nozzle and an insufficient fuel supply to the engine.

General Motors, LLC. (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5 and XT6, Chevrolet Blazer, Silverado 1500, 2500 and 3500 and Traverse and GMC Acadia and Sierra 1500, 2500 and 3500 vehicles. The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.

General Motors LLC (GM) is recalling certain 2020 Buick Enclave and Chevrolet Traverse vehicles. The right-hand frame rail in the engine compartment may be cracked.

I am filing a complaint regarding a persistent safety defect widely known as the "Shift to Park" issue. For over a year, my 2020 Chevrolet Traverse, VIN [XXX] has repeatedly displayed a "Shift to Park" warning message on the instrument cluster when the vehicle is placed in Park and the engine shutoff button is pressed. This occurs multiple times weekly. Despite the vehicle physically being in Park, the internal shifter sensor fails to recognize the gear position. This defect prevents the vehicle from shutting down properly, leaving the electrical system active and causing severe battery drain. Furthermore, because the vehicle does not recognize it is in Park, it creates a roll away risk if the driver exits assuming the vehicle is fully secured. General Motors is aware of this widespread component failure across this vehicle platform but refuses to issue a safety recall or cover the repair costs out of warranty. This is a systemic manufacturing defect that presents a clear financial and safety hazard to consumers. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident Jul 1, 2025

Bracket on the exhaust pipes just before the flex pipes broke free and there is now a hole in the pipe.

Incident Dec 1, 2025

I own a 2020 Chevy Traverse with currently 16,000 miles. I am currently dealing with a know shudder issue that has returned. I have already taken the vehicle under warranty to the dealership where the transmission was replaced on 6/29/2022 at 4919 miles for “catastrophic failure” where the fluids were dark, burnt, and several burnt up clutches. Then the torque converter was replaced separately on 9/20/2022 at 8106 miles for engine shudder. Took the vehicle again in on 7/21/26 for shudder returning at 16,450k miles where diagnostic shows dark, burnt fluid, with metal debri. Repair recommendations are to flush again and if not fixed to again replace the torque converter. There are no open recalls on my vehicle when there should. There is the most recent bulletin, Bulletin No.: 23-NA-072 dated May 2023 that covers the 2020 Chevy Traverse for TCC Shudder: (Typically seen on 4th-5th Upshift as ISS Oscillation) which is referenced on my last car diagnostic report. This car is basically brand new and should never have needed a brand new transmission, torque converter replacement and still having shudder problems. These vehicles need to be recalled for their power train.

Incident Jul 21, 2026

The contact owns a 2020 Chevrolet Traverse. The contact stated that while parking the vehicle, the gear shifter was shifted into park(P); however, the “Shift to Park” message was displayed. The contact shifted the gear shifter back and forth and then shifted into park(P) before the proper gear was recognized. The vehicle was taken to the dealer, who replaced the gear shifter. The manufacturer was made aware of the failure. The failure mileage was 26,818.

Incident Jul 1, 2026

There is a well known exhaust issue with the catalytic converter and the separating manifold and no recall has been issue yet. It causes the vehicle to lose pressure and shuts off in the middle of traffic. The seat belt secure locks are malfunctioning and could cause loss of life in the event of an accident.

Incident Jun 18, 2026

GM published bulletin PIP5681A on 10/05/20 regarding defective welds on the exhaust brackets near the catalytic converter. I had the same exact weld failure and GM is not honoring the warranty coverage, even though their bulletin said that all 2020 Traverse SUVs were included.

Incident Jul 1, 2026

The welds that hold the catalytic converter and exhaust pipe together have pinhole leaks. The hose that connects to the exhaust system is also failing. This has been confirmed by the Chevy dealership we took it too. No warning lights were triggered. We heard a rattling noise after having a prior hose replaced. One week later we were back at the same dealership. At this appointment they discovered the pinhole leaks and confirmed there are pinhole leaks while revving the engine to 1,000 RPMs. We requested GM pay to fix the issue and they have refused. Our safety is at risk because no sensors were triggered and we could smell exhaust fumes in the vehicle while using the air conditioning. This is not the first issue we had with this vehicle. Prior to this the whole car died while my wife was driving it with our 2 kids in the car with her. She had no steering or braking.

I have already taken the vehicle under warranty to the dealership where the transmission was replaced on 6/29/2022 at 4919 miles then the torque converter was replaced separately on 9/20/2022 at 8106 miles for engine shudder. This vehicle is practically brand new. I reached out to GM with no help other than to pay to have it diagnosed again at the dealership. There are no open recalls on my vehicle when there should. There is the most recent bulletin, Bulletin No.: 23-NA-072 dated May 2023 that covers the 2020 Chevy Traverse for TCC Shudder: (Typically seen on 4th-5th Upshift as ISS Oscillation) This car is brand new and should never have needed a brand new transmission, torque converter replacement and still having the exact same problems as before.

Incident May 4, 2026

Getting error message on and off last several weeks - "Shift into park" which does not allow the ignition to be turned off!! The only way to resolve this issue is to jiggle the gear shift or restart the car, changing gears and trying again. Sometimes it works on the second or third try! Frustrating!!! What is it doing to the shift assembly? Have called local dealer they will diagnose and repair at my cost! In the neighborhood of $250.00 for diagnostic, which will be applied to the total repair costs. No idea what that bill will be. General Motors just advises if it needs repair save my receipts in the event of recall for reimbursement. The car only has 21,600 miles!! I have seen other complaints on line and there are videos on You Tube on how to repair this issue, obviously I'm not the only one this is happening to. The gear shift boot and console have to be removed to repair. If the above actions do not work, how do you shut the ignition off??? Just let the car run until it's out of gas??? Not what I would classify as safe! General Motors should be taking steps to rectify this problem immediately but since they have not had "enough" complaints to warrant investigating further they are sitting idly by! HELP!

Incident Apr 14, 2026

This is a know issue on 2021 models. The exhaust bracket is breaking away from the muffler/catalytic converter. The weld is breaking causing the exhaust to break away and both pipes must be replaced resulting in a 1500 repair. Why if it bad in later years is there no maintenance bulletin or mandatory fix for the 2020 models? It was repaired and fixed by McClusky Chevrolet in Cincinnati OH.

Incident Apr 1, 2025

Flex pipe for exhaust is broken at 61000 miles rattles and makes noise upon start up and acceleration.doesnt make sense repairs for model years before and after 2020 are being repaired for free

Incident Feb 25, 2026

While driving the stereo went off, the ac, the car stopped in middle of the road and I lost all electrical. I tried turning back on and the emergency brake light was on and the dash said "Steering Assist is Reduced, Drive with Care.” I was able to put it in neutral and get it out of the way. Battery is good Fuses were all checked 350 replaced Car isn’t starting or Turing over, but some of the lights have turned on.

Incident May 27, 2026

Brakes have screeching noise Transmission jumps when changing gear The shift to park is so constant can not even go out because it takes more than 20 to 30 tries for it to accept park and turn Vehicle off! I have taken it to the dealer for the concern stated no recall or warranty At this point I am afraid to even leave it in shift to park and walk to the store and it gets stolen or leaves me stranded with my children

Incident May 17, 2026

2020 Chevrolet Traverse started to shudder and hard shift between 25 to 30 miles per hour. Vehicle only has 64,925 miles on it (4,925 miles above warranty). Vehicle was taken to garage and told the torque converter along with valve body was needed to be replaced. The torque converter malfunctioned right after warranty expired due to mileage and could have left my family stranded on the side of the road. The components have been inspected by Chevrolet manufacturer and they deemed they needed to be replaced and replaced them. No lights or anything came on the only sign was the shudder and hard shift which if not taken in immediately could put the owner past the warranty mileage. Vehicle was purchased brand new and routine maintenance conducted.

Incident Apr 20, 2026

I have 37,000 miles and have taken it to a Chevrolet dealer for all suggested routine maintenance. It started shuddering so I took in to dealer. They said known issue and may need a new torque converter which would cost approximately $8500. They suggested I try changing the transmission fluid even though suggested at 45,000 miles. They said to drive 200 miles and see if it goes away. I haven't yet put 200 miles but am very concerned there is a bigger issue with the Traverses out there and afraid this is a band-aid and feel a recall may be inevitable. Just wanted to share with you.

Incident Apr 25, 2026

We have had multiple issues with the exhaust system and the brackets that hold the catalytic converter in place. The catalytic converters have been replaced two times in the last 3 years with them currently needing to be replaced AGAIN. This is supposed to be our family car and it is in no way reliable. Not when we have to take it in every couple thousand miles on it to have the exhaust system repaired. We have had it into the dealership multiple times to confirm the problems.

Incident May 1, 2026

Bracket fell off of the exhaust pipe on my 2020 Chevrolet Traverse LT, which in turn cracked the exhaust pipe, making my car create this loud noise every time the car was accelerating.

Incident Apr 18, 2026

The contact owns a 2020 Chevrolet Traverse. The contact stated that upon starting the vehicle, the exhaust system made an abnormally loud sound. There was no warning light illuminated. The vehicle was taken to an unknown dealer, where it was determined that the front clamp on the exhaust system was loose. The dealer tightened the clamp; however, the failure persisted. The contact related the failure to TSB Number: PIP5681A (Exhaust leak, Lean Codes, Rattle Noise, or Catalytic Converter Failures). The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 68,000.

Incident Mar 9, 2026

Issue documented in PIP5681C

Incident Mar 31, 2026

2020 Chevy Traverse High Country Exhaust bank 1 and bank 2. Transmission shudder.

Incident Dec 17, 2025

Failing front exhaust pipe mounting bracket. GM has a special coverage program (N212356540) for 2019-2020 Chevrolet Traverse which covers the repair for 15 years or 150,000 miles from the original service date. The coverage is VIN specific. My vehicle has been having this issue for two years now and my VIN is not covered. This is unfair to the consumer/Chevrolet owners who's VIN's are not listed. This is an obvious ongoing problem for many Chevrolet Traverse owners, it should be an active recall on all 2018-2023 Chevrolet Traverse owners. Especially since Chevrolet/GM is aware of the problem. Most of us are paying off our vehicles because we can't afford a new one and GM is not providing assistance for some of us who at no fault of our own are having to pay for a defect they are aware of.

Incident Mar 13, 2026

Active GM coverage on exhaust falling off, does not include all vins affected. My car is affected by this exact issue reported and refusal to fix or repair issue, because vin “not included” (n212356540) is gm special coverage for exhaust falling off that isn’t including all vehicles affected

Incident Oct 15, 2025

The exhaust has a leak. Loud noise, rattling coming from exhaust. Smell of fumes in the cab of the vehicle. I believe there is a recall for 2018,2019,and 2021 year models for this same issue but no recall for the 2020 model.

Incident Mar 5, 2026

A MANUFACTURER RECALL NOTICE NEEDS TO BE ISSUED ASAP. Exhaust is leaking into passenger cab due to a defective exhaust mounting bracket. Was replaced 1 year ago at the dealer at considerable cost to vehicle owner. Now this defective part has failed a second time. A MANUFACTURER RECALL NOTICE NEEDS TO BE ISSUED ASAP. This presents a health hazard as well as financial loss due to defective manufacturing. Other years of this particular vehicle have been recalled and this defective part was repaired/replaced it is supected to replaced with the same defective OEM part due to its repeated failure. It is unclear why this model year has been discriminated against. A MANUFACTURER RECALL NOTICE NEEDS TO BE ISSUED ASAP.

Incident Feb 2, 2026

ELECTRIC DOOR LOCK OF FRONT PASSENGER DOOR DOES NOT UNLOCK DOOR. PLUNGER TRIES TO MOVE UP WHEN ENERGIZED BUT STAYS IN LOCKED POSITION. DOOR DESIGN DOES NOT INCLUDE MECHANICAL KEY UNLOCK OVERRIDE. A FIRST RESPONDER WOULD NEED NEEDLE NOSE PLIERS TO LIFT UP THE DOOR LOCK STEM. THIS FAILURE PUTS ANY PASSENGER AT RISK OF DELAYED EXIT. THE LEFT REAR PASSENGER DOOR HAD THIS FAILURE MAY 2024, NO PRIOR SYMPTOMS. THE DRIVER DOOR HAD THIS FAILURE A FEW MONTHS LATER. EACH REPAIR COSTS OVER 700, DEALER IS AWARE OF THESE FAILURES. NO WARNINGS OF THIS FAILURE VISIBLE. NO INSPECTIONS MADE OTHER THAN DEALER

Incident Mar 8, 2026

2020 Chevrolet Traverse vehicles may experience a loud, rumbling exhaust leak caused by a failing front exhaust pipe bracket weld, frequently noted in complaints. While special coverage exists for other model years, 2020 owners are experiencing similar issues, with some reports suggesting it may not be covered under the same official, extended recall. My vehicle is experiencing the same issues that the 2019, 2021, and 2022 model are experiencing why is my 2020 and other owners of a 2020 year skipped to be covered for this identical problem.

Incident May 7, 2023

Failed/failing hydraulic timing chain tensionors. Common issue for this engine said to be caused by poor oiling. After speaking to many shops, this is just one of the many, very common issues that occurs in this vehicle. Started on February 20th, 2026. There are no warning or check engine lights on for this issue. People who are unfamiliar with the symptoms may be driving a vehicle that may suddenly stop running without warning as there is no light illuminated on the dash. Online it states that this may be caused by not performing oil change services on time. For my particular situation, I am a preventative maintenance specialist for the past ten years. I am professionally trained and perform PM services daily. I know my Traverse has been very well maintained and serviced with premium synthetic motor oil since my ownership. And despite this, I am now having to pay a significant amount of money to have this fixed or risk the safety of myself, my family and really anyone else on the road. My vehicle is available upon request any time.

Incident Feb 20, 2026

Front exhaust bracket weld failed creating a hole in the exhaust system, as covered by GM Bulletin PIP5681C. This resulted in a loud noise as well as exhaust leaking into the cabin since it is near the engine, right above the drivers center console

Incident Feb 13, 2026

My seat belts do not click when fastened or stay fastened. Sometimes I have to try several times to get the seabelt to click.

Incident Jan 1, 2026

Vehicle: 2020 Chevrolet Traverse VIN: [XXX] Mileage: 50,100 miles Ownership: Original owner The driver’s seat belt intermittently fails to latch. This is a primary safety restraint system, federally required, and critical for occupant protection. The failure occurs randomly and cannot be reliably duplicated. The dealer inspected the seat belt buckle and confirmed no debris or obstruction. The dealer was unable to duplicate the issue during their inspection. Video documentation from the owner of the intermittent failure is available. This appears to be a premature mechanical failure of a safety-critical component. The vehicle is only 50,100 miles and properly maintained. Failure of the driver’s seat belt could prevent proper restraint in an accident, creating a serious safety risk. There are no open recalls related to this issue, and the vehicle is out of warranty. I contacted the manufacturer about goodwill assistance for repair. They confirmed that, since there are no open recalls, the issue cannot be duplicated, and the vehicle is out of warranty, they will not provide reimbursement or cost assistance. The driver’s seat belt should not fail during the expected life of the vehicle. At 50,100 miles on a 2020 Traverse, this appears to be a premature mechanical failure of a safety-critical component. I am submitting this complaint to document this issue for this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident Feb 10, 2026

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

Incident Jan 1, 2026

The contact owns a 2020 Chevrolet Traverse. The contact stated that while the vehicle was shifted into the park(P), the message "Shift to Park" was display on the instrument panel. No warning light was illuminated. The contact stated that the gear shifter was shifted out of park and back into park several times before being able to turn off the vehicle. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

Incident Jan 12, 2026

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

Incident Dec 30, 2025

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.

Incident Jun 14, 2024

The contact owns a 2020 Chevrolet Traverse. The contact stated that while the vehicle was parked and occupied in the vehicle, there was a rattling sound coming from the front of the vehicle while stationary or while driving. An independent mechanic was contacted. The vehicle was taken to a dealer, where it was determined that the exhaust mounts needed to be replaced. The vehicle was not repaired. The contact related the failure to Special Coverage Adjustment: N222385510 (Front Exhaust Pipe); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 118,000.
