2016 Chevrolet Suburban: complete transmission failure

Filed Aug 19, 2026 · Transmission · TX

The transmission failed suddenly and without warning. When I Went to pull out from a stop sign with cross traffic doing 55 mph, the vehicle shuddered and stopped pulling. We barely had enough momentum to get out of the way of oncoming traffic at the last second. The oncoming traffic had to brake and honked. After reading online, this is a common issue with the 6l80 transmission torque converters being a failure point and the fluid temperature being too high. Gm has a service bulletin for a lower temp bypass valve but there is no recall and these units are failing by the tens of thousands.

Just purchased this vehicle used from a business in Moyock, NC. The mileage at purchase was 92,860. We checked Carfax and it showed two previous owners and had a steady maintenance history. On the way home (2 hour drive) and after the vehicle had warmed up it started showing signs of transmission problems. This was not noticeable on the test drive. The RPMs skyrocketed, the car went into neutral, once we got it back into gear it would hardly accelerate. It was a long long drive home! We took it to our local mechanic and must replace the transmission at a cost of $7,000. We will not use the manufacturer's transmission product as a replacement after reading all the complaints that are so similar to ours. Definitely not what we were expecting to have to do within a week of the purchase. There could have been injuries if my wife had not been following me and knew something was wrong when the vehicle slowed down significantly. No one was injured, except for our pride and wallet.

Transmission and Engine Failed. Please inspect. I've had several shops and mechanics inspect. I was towing both times and could have been seriously injured when my transmission went out. Then after that was resolved my engine went out. No symptoms or warnings before incidents occurred.

The transmission shift solenoid stopped working going down the road which caused the vehicle to stall. Going from 65mph to dying without any warning signs no check engine no issues driving before. Check engin came on after the fact took it to a parts store to run the code came back with shift solenoid. More then likely need a new transmission for $6k.

We purchased this vehicle from a local dealership (2/5/2024) and 25 days after purchasing it (3/1/2024) we had to have it towed as the torque converter and transmission went out and we could no longer drive it. This was quite costly at $6600.00.

I purchased my 2016 Chevrolet Suburban from Jupiter Chevrolet on March 18,2021 at that time the car had 74,931 miles on it after driving off it home 35 min away from the car lot I noticed the RPMS would go up on their own I called and asked what the cause of it and they would be said that it was normal because these new vehicle have the downgrade break. I drove it off and on since then this is a vehicle used for when we have a family trip or just store runs. My truck currently has 107,750 miles on it, that is a total of 32,819 miles put on this truck since 2021. On January 28,2023 as I was driving on the highway to the store that is three miles down the road the truck went into limp mode all the sudden Iwas almost hit by an 18-wheeler because it suddenly owed down and would not go over 20 mph. My daughter who is 5 years old was in the car with me at the time. I was able to turn around and slowly get it back home since I was not far, when I got home the check engine light came on I had my neighbor read the code and it said P0700 and P0796 they said to change the fluid and it would probably fix it so I took it to have the transmission oil changed and new filter put in and they told me then that I will need a new transmission because of all of the metal shavings that was in the oil and filter and on the magnet in the oil pan. There is no recall on this problem, I do not have that many miles on my car and have not driven that many miles to be having a transmission problem on my vehicle this is something out see on vehicles with 300k. miles on them. I must have my vehicle and right now I am not able to drive it at all, but I am still having to make the payments on a vehicle I am not able to drive.

While driving at speed between 18-35mph the transmission began to shutter. I attempted to make a left turn and the vehicle would not accelerate as I pushed on gas pedal. I believe the transmission failed almost causing us to be T-boned by another vehicle approaching intersection from opposite direction. This is definitely a important safety concern.

I was getting on the expressway and with no warning as I was speeding up to merge with traffic my RPM’s went through the roof.I felt like I wasn’t going to get up to speed to merge with traffic cars had to slow down to let me on at the end of the merge lane.So I put the cruise on at 50 miles an hour. After I left the expressway it did the same thing when I had to stop at a traffic light, it took a long time to get up to speed limit with cars passing me. I had a check engine light come on as I got home, but I couldn’t back into my driveway like I usually did. No reverse. So I put an OBD-ll reader on it to check the engine light and it was a P0750 for a solenoid. Young’s confirmed this but said I needed a new Transmission and that the one in it was bad, even said it was their bread and butter of transmissions. Now I can see why!

The torque converter/transmission failed in my 2016 Chevrolet Suburban. It started shuddering while I was driving--no warning lights, system errors, info panel alerts or anything--and I came close to losing control of the vehicle, risking the lives of pedestrians, other drivers, myself, and my passengers. The torque converter/transmission problem was confirmed by a 3rd party mechanic, and also by TWO Chevrolet dealerships. Additionally, my mechanic informed me there was an active Technical Service Bulletin relating to this issue: #N212338770: "High Severity Fleet Transmission Torque Converter Proactive Service to Prevent Potential Failure." They told me to take it to a dealership—the dealership should pay for the repair. The TSB even states, "Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through February 28, 2023." However, I have since contacted FOUR different Chevrolet dealerships, and have paid for TWO additional diagnostic testing fees (in addition to the one I already paid my trusted mechanic). I am now out almost $500 and am no closer to having my vehicle repaired and safe to drive. I'm a single mom of 5 so it's rather important I have a mode of transportation that will fit my entire family. I cannot afford a rental for the likely 3 to 6 WEEKS I will be without my vehicle. I'm at a loss and have no idea what to even do next.

TRANSMISSION FAILURE - approximately 4 hours away from home, the transmission failed without warning. No warning lights or prior issue. We were stranded on the side of a major interstate for two hours awaiting a tow truck. After being towed to an independent service station, the mechanics discovered complete disintegration of the unit. There were no incident codes on the computer. A salvaged transmission was located and installed. Upon arriving back home, we had the dealer examine the vehicle which found no lingering issues. Once again, there were no incident codes on the computer.

After replacing my transmission on my 2016 suburban at 83k miles at the cost of $6,097 in January 2022, I was endangered again on 3/2/22 when I attempted to drive on the interstate. My SUV failed to accelerate and the check engine light started flashing. Thankfully, I was able to maneuver and exit the interstate as soon as possible and waited two weeks for an appointment at my local dealer. I did not drive the car on the interstate during this two weeks. I am told that my engine is misfiring and they are going to try to figure out why. My car (that is barely 5 years old - purchased 2/14/17) has both transmission failures and engine problems. And the air conditioner failed. The list goes on and on. the federal safety agency please check into accidents involving chevrolets. I could easily have died on the interstate two weeks ago and no one would have known that it was because my car would not accelerate. I am thankful to be alive after so many close calls with this car, but also fearful for my safety and others.
