| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| Jan 2026 | ENGINE | Cracked flex pipe. Common issue with all traverse models/years. Needs to be addressed and recalled! | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | The forward exhaust bracket weld broke causing a rattling noise and allowing exhaust fumes into the car which is incredibly dangerous. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE AND ENGINE COOLING | 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. | Crash: No Fire: No | 118,000 |
| Jan 2026 | UNKNOWN OR OTHER | 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 | Crash: No Fire: No | Unknown |
| Jan 2026 | VISIBILITY/WIPER | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE AND ENGINE COOLING | The contact's son owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle made an abnormal rattling sound, and the check engine warning light was illuminated. The vehicle was initially taken to an independent mechanic who could not perform the repair. The contact was referred to another independent mechanic, where it was diagnosed that a crack in the catalytic converter had caused a defect within the exhaust manifold. The contact was then informed that the failure was related to Technical Service Bulletin Number: PIP5681C and was referred to the dealer for assistance. The contact had taken the vehicle to the dealer, where the contact was informed that the vehicle no longer qualified for the TSB repair due to the mileage. The manufacturer was notified of the failure and made the same assessment. The contact was then referred to the NHTSA Hotline for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 90,100. | Crash: No Fire: No | 90,100 |
| Nov 2025 | ENGINE | Weld on exhaust was faulty the bracket malfunction. The exhaust system has leak and rattle with exhaust noises, causing the converter fail. | Crash: No Fire: No | Unknown |
| Nov 2025 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2020 Chevrolet Traverse. The contact stated that while driving at undisclosed speeds, there were abnormal sounds coming from the exhaust system. 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. Additionally, the contact stated that there were exhaust fumes entering the cabin of the vehicle. The contact had taken the vehicle to a local dealer, where it was diagnosed, and it was determined that there were cracks in the exhaust pipe and the catalytic converter pipe at Bank 2 and Bank 1 that needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to Technical Service Bulletin Number: PIP5681A. 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. | Crash: No Fire: No | 110,045 |
| Oct 2025 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Oct 2025 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | 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! | Crash: No Fire: No | Unknown |
| Oct 2025 | STEERING | A few months ago I was driving and without any warning the steering wheel would lock up and I couldn’t turn it at all. I had to use my strength to wiggle it to unlock it. It happened several times on busy roads and highways. It’s currently at the dealership for the past 2 months because there is a short and the steering gear box needs to be replaced but the part is on back order with no date of when it’ll become available. I obviously can’t drive it due to the steering locking up and that it’s a danger to not only myself and my family but other drivers on the road. Anyone could have been seriously injured or killed had it locked up and caused an accident. It would happen no matter what speed I was going. | Crash: No Fire: No | Unknown |
| Oct 2025 | POWER TRAIN | Receiving a persistent “Shift to Park” message, after the car has been placed in Park. This causes an inability to turn off my engine completely and is draining my battery. As a temp fix, I've had to wiggle the shifter many times, turn the car on and off, place the car from park into drive many times to get the car to realize it's in Park. Scheduled with the dealership and referenced the TSB that was issued for this specific safety issue (in writing). Brought the car in for the repair and the technician and intake person were both aware of this major problem and have seen other Chevy's with the same issue. Repair is $809.00 for a shifter assembly. [XXX] - [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Oct 2025 | EXTERIOR LIGHTING | 19 Sep 2025. The headlights turn off at night while driving. With the switch in the "auto" position, I turned the switch to "off" then back to "auto" and they came back on for a short period of time. They turned off again, I turned them to "on", they came back on for a brief period. I had to keep switching the headlight switch from "on" to "off" and back to "on" every 20 to 30 seconds (estimated) to keep driving. The dealership could not schedule a diagnosis until 8 Oct 2025. This is a potentially fatal issue. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN | Slipping in low gears of transmission. Shaking of vehicle. Potential to break down. | Crash: No Fire: No | Unknown |
| Sep 2025 | SUSPENSION | Exhaust and catalytic converters keep breaking off causing loud noise and check engine light to stay on | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN | Check engine light came on day after I purchased this vehicle. Cracks in both front exhaust pipes. Seem to be an issue with 2020 chevy traverse models. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN | I recently had to replace my transmission (2020 Chevrolet Traverse) due to shuddering from manufacturer's fault in assembly process. Now I'm having to replace the transmission in my mother's 2018 Chevrolet Colorado that has less than 65k miles. These issues cause power loss while driving. I was in the middle of passing another vehicle when my vehicle experienced power loss. This is a HUGE safety issue, not only for my family but many others that I know that are experiencing or have experienced the same issues. I have 3 family members that have had to have the same repairs as well as over 40 acquaintances. I had assumed with the thousands others that I've chatted with on facebook and reddit that this would have been a recall, sadly, GM/Chevrolet doesn't seem to care that it is their fault that their consumers are having to spend THOUSANDS of dollars to correct an issue that leaves the manufacturer at fault. With the thounsands experiencing the same issue, i feel that those that have already had to spend money should be reimbursed. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | 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 | Crash: No Fire: No | Unknown |
