  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.

  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.

  Muffler pipes are rubbing on the metal that was used to hold the muffler pipes from dragging. There is nothing to stop this from happening. If it’s Rubbing holes in the muffler then it’s allowing the fumes into the ozone layer and also wasting gas and messing the engine up m, causing the engine to read wrong.

  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.

• 12/06/2022· ENGINE

  We brought our Traverse into the dealership for a check engine light. The resulting inspection revealed as follows. The bracket welded from the f-pipe to the muffler at bank 2 was found to be cracked by the DeMontrond Chevrolet Dealership in Texas City, Texas where the vehicle was purchased in March of 2020. I am a non-destructive testing inspector; so, once the vehicle got home, I inspected it myself & found it to not only have a crack in the piping but also severe lack of penetration in the welds. Both of these are original manufacturing workmanship defects. The resulting defects present severe health hazards as the vehicle now leaks CO₂ in a location not visible unless inspecting the exhaust system & as the stress fracture grows around the piping it could eventually result in the piping breaking through or loose under the vehicle while driving down the road. If the piping were to break through then the vehicle would no longer be in compliance with the EPA for emissions by a long shot. As it sits the vehicle will fail a state inspection due to the permanent code the computer is throwing from the leak. The above listed hazards have already been noted by the NHTSA in Bulletin No. PIP5681C & in Special Coverage Adjustment N212356540 Front Exhaust Pipe from GM. The bulletin only states the issues; however, the special adjustment provides the 2019 Traverse drivers with an extended warranty for the above listed issues. I would like to request that the 2020 Chevrolet Traverse be considered for the same extended coverage of 15yrs or 150,000mi via GM for the cost of the replacement of the f-pipe, three gaskets, & the muffler as these are original manufacturing defects. If it was not for the vehicles check engine light coming on these issues would have gone unnoticed until an even further point in time taking us further away from the original warranty of 2yrs or 24,000 which is clearly not a long enough period for these issues to present themselves & be corrected.

  I was driving down the street and my car started to randomly jerk. When I pushed the gas the car got slower. Once in a safe place I pulled over and sat there for a few minutes. When I accelerated again the car had a sound like the car was speeding up, but there was no speed. It drifted. So I crossed the traffic light and pulled over again. I turned the car off. I waited for about 5 minutes, turned the car on and that's when the engine light came on. I had to drive slower to make it home. Once I made it home I put the car in Reverse and noticed that my back up camera was not working as well. I am so frustrated.

  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.

  This vehicle has completely lost power and stalled on the freeway twice. The first time, I was with my wife and children when it happened on the highway. The vehicle stalled in the far right lane of traffic and it wouldn't restart. We had to risk our lives and push the vehicle off the freeway and onto the shoulder while other vehicles raced by. We are fortunate that we did not die or become seriously injured. The second time the vehicle stalled on the highway, my wife was crossing the highway and the vehicle once again lost all power and shut-off. She is fortunate that she was not killed in a T-bone collision. The first time, there was a dash warning stating to SERVICE ESC. The second time, there was no warning lights or dash illumination of a problem beforehand. The vehicle has been taken to the Chevrolet dealership twice. They ran a diagnostic and stated the starter was pulling too many amps which caused the vehicles fuse block to blow, resulting in total failure of all vehicle components. Total repair cost for first repair was approximately 1,000 dollars. We are awaiting the service advisors diagnostic for this second incident. The first repair is covered under a 2 year unlimited mile warranty so hopefully when they replace the starter and fuse block this time, they will also find the root cause of the problem. I feel as if our lives and well-being are in jeopardy since the first incident and we no longer feel safe driving this vehicle which has stalled twice during highway conditions. I am confident that we will no longer be GM consumers due to these life risking incidents.

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.

  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.

  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.

• 11/06/2025· 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.

  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 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.

  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.
