| Apr 2024 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING,ENGINE | Sunday night 4/7/24, I was on my way to the emergency department with my 5 month old baby to be seen. 30min into my drive i came to a stop light when my truck completely shut off (BLACKOUT) No Power, NO LIGHTS not even my hazard would turn on, my car wouldn't go into park or allow me to press on my breaks it was like they were glued stuck. all my doors locked and I couldn't get them to open, not even manually because of the nobs that go all the way in. I couldn't put the car into park or anything just got locked in my car and I couldn't even hit the OnStar because everything was off! I started to see cars coming from a distance so i started to panic because they were going to rear end us really bad, so i broke the driver window and went to warn drivers to please stop by putting myself at risk to get hit by a car because i didn't know what else to do, i had a 5month old baby in the back seat that would have died if I didn't pull her out and we got hit. I started to scream for help because it was dark and we were stuck. two cars came inches from rear ending us, which caused an accident between the two vehicles. thankfully a police officer was passing by and got behind my traverse to stop traffic. but if it wasn't for the cop i don't know what the outcome would have been. THIS IS A HUGE SAFETY ISSUE. IF THE CAR WAS ON FIRE WE WOULD HAVE BURNED. THIS NEEDS TO BE RECALLED ASAP. Why would they design a car where you cannot get out. and why did it shut off like this. ???? I NEED ANSWERS PLEASE. I'M TERRIFIED TO DRIVE MY CAR AND THIS WAS A $38,000 VEHICAL THIS IS NOT OK!!!! | Crash: Yes Fire: No Towed | Unknown |
| Mar 2024 | SEAT BELTS | Drivers seat belt not able to click and stay also passengers seat belt is hard to get it to click in. The second row on left side seat belt won’t stay clicked in. | Crash: No Fire: No | Unknown |
| Mar 2024 | ENGINE | After routine oil change in January 2023, rattling noise under car was noticed. Returned to dealer who stated front mounting bracket had cracked. Was informed by technician to take vehicle to muffler shop nearby to have bracket welded due to them not "doing" weld jobs there. Had both bracket and crack in front pipe repaired in June 2023 mileage 68,660. February 2024 Noise returned and steadily grew louder. On March 3, 2024 while turning onto neighborhood road, loud bang was heard then car sounded like it was roaring and was barely moving when pressing gas. Made it to driveway and at ignition cut off, gurgling fluid sound was heard. Towed to Hardy Chevrolet on Tuesday 03/05. Mileage 82,059 Still waiting on full diagnostics but front pipe has completely detached at right passenger cat. Bolts stripped out? I will not be able to pass State mandated emissions testing until repaired. This problem was recalled for the 2018, 2019 and 2021 vehicles, but for some reason not 2020 for the exact issue. The dealership wants to charge for a known safety issue. 2021 - GM Special Coverage (N222385510) 2019 - GM Front Exhaust (N212356540) | Crash: No Fire: No | Unknown |

| Feb 2024 | ENGINE | While driving at low and highway speeds, I began hearing a rattle under the vehicle, along with a loud exhaust noise. I looked at the undercarriage of the vehicle and observed a broken bracket on the exhaust pipe causing a hole in the exhaust pipe. I searched and found this was a common issue with this make and model of vehicle. | Crash: No Fire: No | Unknown |
| Feb 2024 | ENGINE | The front mounting bracket has separated from the front exhaust pipe. Because of this the exhaust pipe has developed a hole around the bracket, leading to a leak and increased exhaust noise. My check engine light is on constantly and will not be able to pass State mandated emissions testing until repaired. This problem was recalled for the 2018, 2019 and 2021 vehicles, but for some reason not 2020 for the exact issue.

| Feb 2024 | POWER TRAIN | The transmission failed in the middle of me driving the check engine light popped on and started jerking and accelerating and slowing down in the middle of traffic. It is available for inspection. Stopping randomly and jerking as soon as the light popped on. I am about to be out of thousands of dollars for a 40000.00 car that I'm still paying on always kept maintenance up and just had an 180.00 inspection at dealership prior to this no mention of a transmission failure prior. Everything came back good so this is frustrating several other 2020 traverses have been recalled due to transmission I am not sure how mine isn't included for same year. It conveniently happened right when it wad out of warranty. | Crash: No Fire: No | Unknown |

| Dec 2023 | AIR BAGS | Due to a death in the family, we were traveling back from a funeral. We were miles away from another freeway change when a deer came from the ditch and darted in front of my vehicle. With no time to react, I braced for impact. Going at a high rate of speed, I was bracing for airbags. At the time of collision all the safety features engaged. The seatbelts locked in place, hazard lights turned on, and my vehicle was slowing, but my airbags did not deploy. They did however release a white powder substance. I was safely able to get my vehicle off to the side of the road and evaluate the situation. My husband was moaning and grunting in the passenger seat. My three children are scared, frightened and worried. As we were attempting to unbuckle and exit the vehicle to assess the damage, we were unable to free ourselves. As the seatbelts locked, and had no wiggle room to disengage the latch. We had to move the seats back, to allow room to unbuckle. With the impact we received and the size of the deer struck. The insurance has deemed the vehicle a total loss. After many questions, and multiple attempts to get answers. All I have is the airbags should have deployed, with the evidence through the car with the white powder at airbag locations. As I thank to not be as injured as we could have been. Having my whole family walk away with minor bruises and many aches. My heart is broken, I am shattered and unable to process the incident. Having put so much faith in a vehicle to protect myself and others who I love. I feel jaded, lied too, and unable to trust car safety. My heart is unable to let this go and have others being in danger with no airbag protection in an accident. | Crash: Yes Fire: No Towed | Unknown |
| Nov 2023 | POWER TRAIN,ENGINE | My vehicle along with many other make a stuttering feeling when accelerating at low rate of speed. This can lead to a bad transmission and causing the vehicle to cut off making a hazard. | Crash: No Fire: No | Unknown |
| Nov 2023 | POWER TRAIN | In the past 3 years I have received 2 check engine lights giving a code of P0420, meaning the catalyst system efficiency is below threshold. Chevy replaced my catalytic converter in April of 2022… now a year and a half later they need to replace parts again. A catalytic converter is an important exhaust and emission component that is designed to burn up the toxic exhaust gases that come from the engine… carbon monoxide and hydrocarbons to be exact. I just found out today after taking it in for a second time that the first replacement of the catalytic converter was a defect on the manufacturers part. Every time I go in I have to pay the diagnostic cost and I feel as though I was sold a defective car. Catalytic converters are supposed to last the cars lifetime in some cases. | Crash: No Fire: No | Unknown |
| Oct 2023 | WHEELS,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Oct 2023 | WHEELS | The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 55 MPH, the contact heard an abnormal sound. The vehicle then started shaking uncontrollably. The contact was able to pull over to the right shoulder. The passenger’s side rear tire had separated from the rim. There was no warning light illuminated. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 55,000. | Crash: No Fire: No | 55,000 |
| Sep 2023 | ENGINE AND ENGINE COOLING | Good morning, I have an issue with my 2020 Traverse that GM refuses to fix. I am getting warning lights from leaking exhaust. This is to due to weld defects. GM knows of the issue, they did recalls on the 2018, 2019, 2021 models but won't fix my 2020 even though it is the same issue. GM has a safety bulletin PIP5681 and PIP5681A for this issue. N222385510 is the number for the 2021 recall. The dealership has told me that this absolutely should be recalled but GM will not allow them to repair the 2020 under the same recall number. Thanks for your help! | Crash: No Fire: No | Unknown |
| Sep 2023 | ENGINE | I was told that my muffler needed to be replaced and not covered under warranty this vehicle is not even 3 years old yet and I need a new muffler my car sounds LOUD and the check engine light is now on. | Crash: No Fire: No | Unknown |
| Sep 2023 | BACK OVER PREVENTION | When I place the car in reverse, the rear view image does not show on the display screen. This is a recurring issue when it’s approximately 75-85 degrees out. I did some research and found information on where you have done a recall of the 2020 Acadia for the exact same issue, requiring a replacement of the coaxial cable. I wanted to let you know the same issue is happening in the 2020 Traverse. | Crash: No Fire: No | Unknown |
| Sep 2023 | ELECTRICAL SYSTEM | When the vehicle is shifted into "Park" the information system reports an error code "shift into park" and prevents the vehicle from being turned off. On the opposite side of the spectrum, there are times when the vehicle fails to start with error code displayed "shift into park" even though the vehicle is infact in park. The error code is sometimes resolved when the shifter levers forward facing button is actuated multiple times. This false error code is a grave safety concern as it build complacency within the operators. This could potentially lead to an operator ignoring a true "shit into park" error code as a false one and exiting the vehicle while it is actually in gear or neutral and cause death or injury to an innocent bystander or the operator! Please investigate this error as it has apparently existed and been well documented in the Chevrolet Traverse since at least 2018. Yet Chevrolet still fails to acknowledge or resolve it! | Crash: No Fire: No | Unknown |
| Sep 2023 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | The exhaust pipe and muffler developed a hole in both exhaust components at less than 32k miles. This is a known design issue for the model as a previous model year had a special coverage adjustment on 03/2022 [XXX] . It is apparent this is a design flaw that wasn't fixed for the 2020 model year. GM has only offered 50% of repair costs. I am requesting the NHTSA to open review of exhaust failure for the 2020 model year of Chevrolet Traverse, GMC Acadia, and Cadillac XT6 that are equipped with the 3.6 liter V6 engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
