The contact owns a 2020 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. A passerby helped the contact to push the vehicle into a parking lot. There was no warning light illuminated. The contact left the vehicle in the parking lot. The following day, the vehicle restarted as intended. The contact stated that on a separate occasion, the vehicle failed to start. The Push to Start button occasionally became stuck, and the contact continuously pressed the button to release it. The vehicle was towed to the dealer, but no cause for the failure was found. The vehicle was taken back to the residence, and upon exiting the vehicle, the contact noticed loose cables. The contact's husband plugged the cables back into place. The failure persisted, and the vehicle remained at the residence unrepaired. The contact had not driven the vehicle due to safety concerns. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

Transmission is not functioning properly at 74,300 miles. Engine kept slipping while driving uphill and the RPMs were not matching vehicle speed. Could not go above 50mph while merging onto freeway which was very dangerous. Whirring noise occurred every time I accelerated which was also noted By dealer and transmission shop. No check engine lights on. Took to dealer, but the misdiagnosed it since no lights were on. Took to Transmission shop, and they found that the transmission had several issues that were not displayed. Besides the shop running specific tests, there are still no warning lamps or messages displayed on the vehicle dashboard or using an OBD2 sensor.

Our engine went at 100,800 miles, costing us $15k in June 2025. Then our transmission went 3 months later, now costing us another $7k. GM is offering very little financial assistance. It's quite inconvenient that these major mechanical issues occur right after factory warranty. It is at a dealer getting fixed, again, but how can this be ok with GM to see their product be such a failure for consumers? Recall or not, this has left a horrible taste in our mouth for GM/Chevy vehicles. We will no longer trust the longevity of their vehicles and will educate others to be weary on purchasing vehicles. We can understand mechanical failures over time, but not to this extent, and we're very disappointed in the customer service and available assistance for someone that just spent nearly $23k on a vehicle that's less than 5 years old.

Driving through residential area and noticed loud noise from under hood. Went to pull out onto state highway and wasn’t able to get up to speed almost causing an accident because I could not accelerate. Had to maintain speed at or below 40mph. Brought vehicle to dealership and they confirmed that the transmission was shot. Also went to a local transmission repair shop and he stated that he sees 1-2 of this same transmission weekly. That 2016-2020 Chevrolet transmissions are no good and that Chevrolet knows this. This is a $7000 repair on a vehicle that just hit 100,000 miles. Vehicle has always been well maintained. Just wondering how GM doesn’t have a recall on this particular transmission if there are so many reported problems with it. I was fortunate to be able to pull off of the highway and take back roads to get to the dealership. There was no slipping, no warning signs whatsoever. It just made the loud noise and then boom. Done.

Severe transmission shudder. last month had taken my 2020 chevrolet suburban to the west chevrolet dealer located in alcoa, tennessee. I was advised by a tech that the vehicle needed a new torque converter. I paid 2,200.00 for this repair. This repairs did not fix the issue. After paying my bill and driving through the parking lot, it started back immediately. The technician advised their was nothing else they could do after expressing how big of a safety concern it. So I attempted to drive it home. As I entereded into a busy 4 lane highway (alcoa highway) the vehicle would move and began shudder very bad, almost causing a crash. after doing lots of research, it appears I am not the only one having this issue. I have also reached out to several news meadia outlets to assure this IS addressed to prevent by family getting hurt and/or killed due to the failure of the 6L80 transmission problems. please take into considerations of the seriouness of this issue. The vehicle needs a new transmission that I can not afford. The vehicle has no codes/warning displayed on the dash which puts my famnilt and I at risk when driving.

The vehicle has 70,000 miles. The engine has failed and been replaced two times. We are on the third engine. The first time was in 2021 the second time was in 2024. I heard that others are having a similar issue. This is a 2020 .6.2L RST. The engine failed the first time while driving at high speed the car just stopped working. The second time we heard it failing and were able to drive it to the dealer where the engine fell apart in the parking lot The vehicle has had other issues too. Currently the wire harness has failed. This has happened several times but the dealer has not figured out a repair. Each time it’s failed while driving causing power steering to fail while driving. I don’t not trust my teen drivers around the vehicle or to drive.

The technical service bulletin for the Service Safety Restraint System is for models 2021-2023. I have a 2020 Service Safety Restraint System error code this is appearing intermittently. Turning off and on. It's almost like a short somewhere. We are taking it in for servicing but I feel that the service bulletin should include the 2020 model as well.

Driving on the highway and I started to slow down even while pressing the accelerator. Pulled over and turned the car off and then back on. I was able to almost get to an exit but then it completely stopped moving. Turned it off and on again but car would not move. Not a single light turned on until the last time I attempted to move the car. Had it towed to Chevy dealer and transmission was completely out. Had 2 different mechanic places (dealer and private) tell me that it is extremely common once a 2020 suburban hits around 100k miles. That is completely irresponsible of GM to not put something out so that owners can at least have knowledge that there could be a potential problem. No warning signs, no lights on that is an accident waiting to happen and a potential wrongful death lawsuit coming your way if something isn’t put out.

Out of the blue, while driving, my car started lurching and making a weird rattling noise. I was able to make it to a mechanic, where I learned the cylinder lifters collapsed and crankshaft were broken. The mechanic told me this is a common defect for GM motors. My vehicle is only five years old, so to learn we have a $10-20,000 repair on our hands was paralyzing and devastating.
