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.

Front Flex pipe broken after failed weld. Issue is known by GM/Chevorlet and has been corrected on all years Except for the 2020 model year. Not sure why 2020 models were left out because they have the same condition.

Purchased the 2020 traverse on [XXX] from Basswood in Ft. Payne Alabama. Under the guise of the salesman I was assured that the vehicle was in great shape, with no issues at all, and a very clean Carfax. Well I'm new to purchasing a car via financing with a co-signer in which he was assured the vehicle was in great shape. Well unbeknownst to us my household the car was nothing of the sort. Within a few days the Start/Stop malfunctioned to the point it would not restart 98% of the time without sounding like a Demo Saw, it's a dangerous problem and there's times we smelled fuel once we were able to restart the vehicle. The front right wheel assembly looks as if it were on fire and if that's brake dust and it has a grinding whomp whomp sound when in motion, that's really not good no wonder it's hard to stop at times. The front end sounds like drums when going over bumps, speed bumps, road imperfections etc.. on morning start-up there's an absurd amount of exhaust coming into the cabin area, the codes [P3055 and P3056] are registered from the computer of vehicle. Now the smell of fuel is blowing through all vents whenever the defrost is running or all vents are used front and rear, with the truck in motion. It was so bad today that my entire family had to pull over to a gas station and get fresh air our eyes were burning and my [XXX] son nose started to bleed., so that's two parents and 6 children scrambling for safety. This is our only reliable vehicle other than an old 99 suburban that is hardly even road worthy anymore. I spoke with several people that have purchased vehicles and all agreed that the salesman and mostly the sales managers knew that the vehicle came from an auction and was never serviced nor inspected at the basswood dealership, which equates to them actively concealing major effects and problems with the vehicle in question. Just to make a one time commission on a fraudulent deal! They didn't provide any inspection papers to me! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

The exhaust bracket on the front broke, and caused my catalytic converter to crack and have an exhaust leak. I-??ve talked to different exhaust places and said it is common in the 2020 traverses. The car is running rough.

2020 traverse was at Chevy dealership for state inspection & emissions test, maintenance service- oil & filter change, rotate tires, check all systems, update system & computer, flush & fill all fluids in car. Chevy certified technician preformed vehicle health inspection, multi point inspection. Car was not picking up acceleration will on a 351 mile trip alone, after stopping I notice the car hood was not on correctly when opened the oil cap was not in place but was on molding, oil had been pouring out leaving engine with no oil, the technician had not replaced cap during service and had no replaced brake fluid, antifreeze coolant, washer fluid and transmission fluid. He had force closed the hood, which could have opened at any time while driving, there was oil pouring from vehicle causes hazardous driving for myself and everyone else on highway. Car has OnStar coverage as well as Chevy safe driver function-??s, and alerts on all systems all fluid levels, tire pressure, temperature ext. non of these alerts showed or alerted me putting my safety and the safety of others on the roads in danger. The technician in fact disarmed these systems and alerts when servicing my vehicle. Ciocca Chevrolet dealership in Quakertown pa, caused permanent damage to the engine and power train system, as well as putting myself and others in serious danger. 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.

My rear exhaust manifold cracked, was told there should have been have been a recall on them bc they are defective. GM is covering 2019 and 2021 Models, but not 2020 models. I had to replace my alternator at the Chevrolet dealership 6 months ago. In the last month, have had the shift to park message come up on my car and that has something to do with the transmission.

According to Special Coverage bulletin N242445280, some 2022 Traverse units may have a condition where the mounting bracket on the front exhaust pipe can separate from the pipe. If this event were to occur, a hole can develop in the exhaust pipe at the bracket location, and a ratting or increased exhaust noise may be present. This is exactly what has happened to my 2020 Traverse. I took the car to the Chevrolet dealer where I was told that the recall did not pertain to my VIN. While that may be the case now, I am complaining to have this exact same issue applied to the 2020 and 2021 models as well. This design is exactly the same and should be included. My Traverse has an awful rattle where the bracket has broken off and a hole has worn through. It also throws a downstream 02 exhaust sensor code.

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!!!!

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)

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.

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. The problem has been diagnosed today 2/12/24 by my dealership but they want to charge for a known safety issue. 2021 - GM Special Coverage (N222385510) 2019 - GM Front Exhaust (N212356540)

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.
