POWER TRAIN
Transmission started shifting very hard while in motion. The vehicle shudders while at speed. Extremely loud vibrations coming from under the vehicle. This vehicle only has 75 k miles on it. Mechanic first flushed and changed transmission fluid. Vehicle still shifting and running rough. Mechanic says we have to replace the entire transmission. Vehicle has always had top routine maintenance done. This suburban is too new to require a new transmission. Chevrolet needs to recall this issue and replace at their cost! Lost power while on interstate at 65 MPH. Extremely unsafe!!

POWER TRAIN
Transmission malfunction. This has appeared several times at highway speeds and low speeds. We have dad to limp along in the slow lane to exit ramp and take back roads to the nearest dealership. The current problem has been confirmed with error codes P0747. The dealership has scanned this vehicle and detected error codes in the past on two different occasions and found P176C in TCM on 08/01/23 and P17D6 on 10/24/24. Check engine light comes on with a screen prompt “Reduced Acceleration Drive with Care”. The transmission valve body has already been addressed once because of triggering limp mode.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was driving when I received messages saying service ESC, Forward collision System Unavailable, & Service Traction Control. The vehicle began to shake hard when I applied brakes, had loss of power when pressing the gas pedal, and sounded like metal grinding. All of this put my children & I at risk as we were on interstate 35 with cars flying past us and I’m losing power. Initially the spark plugs and coil was were changed to no repair. It was towed to a dealership where they confirmed the lifter & cam failed which put metal in the oil. My only option is a full engine replacement costing 20k on a vehicle that’s 4yrs old. It’s not ok that I have to spend that in order to get my 70k car drivable. Im now without a car, still paying a car note, unable to get my kids places, and having to get help from friends all bc GM can’t build a quality vehicle. I also haven’t been able to get a loaner car. This isn’t happening in only the 6.3L. This is a widely known issue with the 5.3L as well. *There were ZERO warning signs that something was wrong. Drive just fine that morning*

The vehicle only has ~39,000 miles on it and the transmission went out and the car is not drivable. The dealership said it is a faulty valve body and that the part is on national back order and could take 2 to 6 months or even longer to get the part before they can start work.

ENGINE
What component or system failed or malfunctioned, and is it available for inspection upon request? - Initially, the vehicle began making loud 'clanking' sounds from the engine, which immediately affected the ability to drive the vehicle. Upon further inspection by a third-party mechanic, it was determined that the Crank Shaft had malfunctioned. This is a known recall for our vehicle type (model, year, engine), however, no recall notice has been received at this time. How was your safety or the safety of others put at risk? - The vehicle was slowing abruptly while in drive mode, potentially causing a vehicular accident. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes, we did not deliver the vehicle to a dealer, as no assistance was initially offered when we made an attempt to call and inquire. However, a third-party mechanic was able to determine the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? - Not at this time, as the dealer we initially inquired with did not seem inclined to assist. We consulted with a third party. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? -No. Failure messages or icons came on after the engine failure began

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
My Onstar system is not working properly. I first noticed the Forward Collision light then the Wifi hotspot features not working. Reached out to onstar they couldn’t help then referred to dealership. Visited dealership 8/12/2025 was told there’s no error code although they see what’s happening. Doing further investigation of my own i found out this is a very well known issue amongst General Motors, Onstar and the dealerships selling these vehicles. There are varying issues customers are having from wifi not working to vehicles completely shutting down in traffic. Once my visit to the dealership commenced i was informed the Telematic Control Module” is on back order with no estimate on deliveries as there’s “others waiting also” this is a scary situation. I am worried that my issue is going to progress into a bigger problem. I drive 23 miles to work and 23 back. I am scared that my module will eventually fail when i am on the highway…..this is terrifying! Over 80k to play roulette.

ELECTRICAL SYSTEM
My vehicle suddenly stalled while driving. I later replaced the battery and discovered the telecom module was damaged, making the OnStar system inoperable. GM disagreed with my warranty claim and required me to replace the module at my own expense. I discovered the same issue is common in various GM models from 2023-2025. My Suburban and Yukon both have the same issue, making them defective. However, GM will not provide a free replacement under warranty.

ENGINE
The motor on this vehicle has been on recall since April of 2025. Several phone calls and a cancelled appointment by the dealership has netted a consistent "we have no information and aren't ready to fix the vehicle." Today, I was directed to the NHTSA to self-monitor when my vehicle would be ready for repair or inspection. Meanwhile, I drive a Suburban because I have five children that I am constantly transporting to school, sports events, scouts, etc. I have grave concerns over an engine failure while I am transporting my children and the risk of an accident.

FUEL/PROPULSION SYSTEM
I was standing at a red light with my foot on the brake and the car went into neutral and stalled. I could not restart the vehicle and had to be towed to the dealership where there confirmed a fuel pump module failure. There were no precipitating factors or warnings. This is extremely dangerous. The car is only 4 years old and many people have reported the same incident online, which often recurs, even after replacing the fuel pump. The dealership has ordered the part however it is on backorder without any estimated ship time. For a vehicle I paid over $70K for, this is concerning and frustrating. There is a known recall for 2021 Suburbans for this exact issue.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My vehicle completely shuts off while driving. All of the components on the dash and even my steering wheel moves into the prestarted vehicle position. It has happened 3 times in the past week now. One particular instance, I was on the highway and thankfully it came back on immediately before completely stopping but shutting off while driving 65mph is so dangerous.

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.

ELECTRICAL SYSTEM, ENGINE
The engine light comes on and then the rpm's drop to 35 and a notification comes up that says "reduced acceleration. driving with caution". If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. The most recent time they've had it for 5 days and still do not know what's wrong with it. The engine light will not turn off.
