6L80 transmission failure at only 82k miles. This is a known Chevrolet fail point on all vehicles equipped with this transmission yet Chevrolet does nothing to recall or repair the issue. Customer absorbs full cost of repair ($6k) and chevrolet acts like they know nothing about it. This happens on the highway at speeds and vehicles suddenly have no drive putting occupants at risk of other traffic and trying to get off the roadway where there may be no safe zone to stop.

Transmission failed at 82,000 miles. Had to be completely rebuilt. Paid $5,486.87 out of pocket. (see receipts attached)

Transmission sudden failure. We were driving down the road when we suddenly lost all power to the wheels. No ability to accelerate or maintain vehicle speed, only coast with the remaining speed we had like it was in neutral. No warnings or trouble light, no noticeable symptoms ahead of time. I would press the gas pedal and the engine would Rev high like it was in neutral. I had just pulled out into the flow of traffic and the cars behind me soon had to all come to a stop because i lost accelaration and had nowhere to go with parked cars along the side of the road. Luckily we were not on a really busy road and could eventually get out of traffic. I can only imagine how bad it could have been if I was in the middle of highway traffic, or going up a snowy hill, or trying to cross a divided highway, etc. The car had to be towed to the nearest dealership and is awaiting repair. The dealer says the torque converter failed and subsequently damaged the transmission fluid pump and will require the entire transmission to be replaced and cost us over $6600. It should be available for inspection but I guess you would need to contact Blaise Alexander Chevrolet of phillipsburg pa. I don't know if anyone else has inspected it. I suspect this is a very well known issue/defect. Other mechanics I talked with instantly guessed the failure before the dealer could tell us. I have the 6 speed transmission and I see there is a class action lawsuit for the similar 8 speed failures.

While driving at 70 mph transmission went out. Shifted from N back to D but no response. Coasted to shoulder of interstate and stop. Shut off vehicle and restarted but vehicle would not move. Shut off again and restarted this time if went into D. Could not any faster than 35 mph. Transmission would not shift automatically. Tried manually but same results. Was able to exit interstate. Got vehicle to Chevy dealership and was told I needed a new transmission. Vehicle has 106,000 miles.

1 vehicle electronic panel not working properly.. transmission making loud noise and now slipping due to normal driving unsafe while at traffic light locks lock and unlock by themselves vehicle now unsafe at 5;000 miles felt strange shifting now I had to spend 1900 dollars for broken motor mounts I believe these motor mounts were already broken I bought this vehicle with 3500 miles on it I believe the motor mounts were already broken now 140;000 miles and transmission is either done or electrical issues

While driving on interstate 465 in Indianapolis on Tues 9/12/23 my 2017 Chevy Suburban completely lost any ability to accelerate. Fortunately I was able to coast over to the shoulder and have the vehicle towed to the closest Chevy dealership. The dealership determined it was a catastrophic failure of the transmission and recommends full transmission replacement for the vehicle to be drivable again.

A Chevy Suburban is a vehicle made to transport large families. You would assume these are made with true utmost safety precautions in mind to protect families. At just over 47K miles on my vehicle, our transmission went out, even though we have regular maintenance completed on our vehicle. The check engine light came on while driving on the highway. Was able to make it to a shop who verified it was the transmission. Took it to the dealer who also confirmed it is the transmission, and their 4th one on a newer Chevy Suburban to come in just today. They said they have 37 on the lot with transmission issues on newer Chevys, and some blew out while driving. We were very fortunate it did not blow out while driving, but it’s unacceptable for a family car’s transmission to go out with so little mileage. This has to be a major defect and cause for concern.

The electrical system has gone out completely comes back a few seconds later with different icons saying to roll driver side window down then up, or stabiltrax. It has also caused complete electrical failure being on a road while driving. This has also cause my wheel to jerk taking out the power steering and the engine has shut off completely to the point where I have to wait a few minutes to even turn it on. This has happened while reversing in to a parking spot and the whole car dies. It kills power so much that I have no hazard lights. When I’m able to get it to come Back on it’s like it reset its self. I have taken it to the shop and they have said the battery cables and the mega fuse above the battery. I know this is a known issue in other like vehicles.

I was driving on the highway at 50 mph with my 3 kids and my vehicle stop accelerating . I almost got in a major Car accident . I had no warning lights at all . I contacted the dealership to tow Car and the transmission failed internally, I ask for Assitance since the 8 speed transmission has a class action lawsuit and Chevy denied Assitance since I have a 6 speed transmission. I believe this is a safety issue that may cause fatalities driving with children and no acceleration at 50

At 105000 miles the torque converter on the 6L80 transmission failed. I am having my transmission rebuilt.

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission had a failure. The torque converter along with a valve assembly failed which caused metal to go everywhere inside of the transmission case. Per the transmission shop that completed the rebuild, they have seen this exact problem numerous times before and have fixed it. Rebuilt kit included cooling bypass, billet torque converter and other parts to rebuild transmission. Vehicle only had 85K miles on it and is a 2017. Price to rebuild was $4000, and dealership quoted almost $6000 for a reman. How was your safety or the safety of others put at risk? Vehicle transmission disengaged while attempting to merge into traffic on busy road. Vehicle was stuck in middle of intersection with 3 small children in the back while vehicles were passing at high rates of speed on a 45mph limit roadway. The vehicle was unable to be safely moved until good Samaritans were able to push the vehicle in neutral to the side of the roadway. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle transmission was inspected by both a local Southern NV Chevy dealership as well as a Transmission shop and was confirmed to need replacement due to the damage from the vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The parts that were removed from the vehicle were not inspected by any of the above parties. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No error codes or MILs were present before, during, or after the transmissions failure. Repair invoice available upon request.

Hi, there! I know a few people that have the same car as me Suburban/Yukon/Tahoe and everyone had to replace their transmission. My car has about 78K miles on it and I need to replace the transmission as well. It jerks really bad. When I press the gas pedal it doesn't move for like 2 - 3 seconds, but after that, it takes off like crazy. It seems very unsafe to me. Please look into it.

The transmission jerks a lot, especially when taking off. I know 4 more people that drive a Suburban, Silverado, and Yukon, and all of them had to change the transmission before 100k miles. The dealer doesn't want to fix it, cause the warranty expired, but how is it fair for us consumers to pay 60k for a car that only lasts 5 years? When I called the dealer, even the technician agreed that they have a lot of problems with the transmission and are booked a few weeks ahead just to take a look at it. Please advise. Thank you.

Engine begin clicking or knocking late January 2022, took to dealer and they diagnosed bad lifters, camshaft failure and piston failure. New engine took 4 months to acquire and install, was told by dealer there are 1400+ Suburban waiting on new engines for related issues.

The vacuum levels have dropped, causing a huge increase in braking effort. I could be rolling backwards in reverse and have the brake pedal all the way on the floor with all my strength and my car will still be rolling and eventually come to a stop. This is very unsafe and dangerous for me and also for others because it could cause me to roll into someone else’s vehicle. There has been a recall on this issue but I do not believe my car was serviced for it and it is no longer on the recall list. This is something that can be inspected at anytime seeing as it is only getting worse. Another issue I am now having is my transmission is kicking when going in and out of reverse, it won’t shift out of second and my transmission is now having to be rebuilt. I have no service lights on, no warnings and this was very sudden and out of no where.

Vehicle became hard to stop/pressing brakes while pulling into my garage. Had to stomp the brakes hard to stop. There were no warnings prior to this issue. No check engine alert etc. Upon research, I see that there was a recall for a flaw with the suburban’s powered brake-assist system. When I put in my vin number it states that my vehicle is not included in the recall however this is the exact problem I am experiencing.

While driving my vehicle, it started to shudder and shake. The Vehicle acted like it didn’t have any power. I was on top of a hill, and the car would not go. I tried park, drive, reverse and nothing. I had my 8 yo in the car in a dangerous area. I had to put the vehicle in neutral and drift down a hill, hoping no one would be coming to get to a safer place to get help. My car was towed. When they flushed the transmission there was metal shaving, which I now learned this has been an issue with these power trains. My vehicle is just at 60,800, which is just 800 miles over the gmc warranty.

Transmission failure at 66,909 miles on 5/19/21. Dealership has original replaced transmission. Our safety was put at risk by breaking down and not being able to move vehicle to a safe location. Advised by service agent at dealership that a lot of 2017 Chevrolet suburban transmissions have had problems. The problem was confirmed by dealership and a remanufactured transmission was installed. I have invoice from dealership describing issue and work done. No warning lamps or messages advised of the problem. Slight Transmission slippage started on 5/18/21 complete failure the next day.

VEHICLE DASH AND HEADLIGHTS TURN OFF WHILE DRIVING, ENGINE STALLS AND DIES, POWER STEERING BECOMES INOPERATIVE. TRANSMISSION POPS OUT OF GEAR AND FREEWHEELS. SERVICE STABILITRACK LIGHT. VERY DANGEROUS SITUATION FOR MY WIFE AND 5 KIDS WHEN THIS HAPPENS ON CURVY BACKROADS AT NIGHT LIKE JUST HAPPENED LAST NIGHT! THIS IS ALSO THE SAME PROBLEM AS OUR PREVIOUS CHEVY TAHOE SO WE KNEW THE PROBLEM WAS LIKELY RELATED TO POOR QUALITY BATTERY CABLES THAT ARE DEGRADING PREMATURELY. THIS SHOULD NOT BE HAPPENING ON A 3-4 YEAR OLD VEHICLE. AFTER SEARCHING A GM WEB FORUM AND FINDING OTHER PEOPLE COMPLAINING ABOUT THE SAME ISSUE, THERE WAS A REFERENCE TO GM TSB 18-NA-161 ON THIS EXACT ISSUE I AM ABSOLUTELY AMAZED THAT GM HAS NOT DONE A RECALL ON THIS YET, AS IT IS A MAJOR SAFETY FAILURE LIKELY TO CAUSE A CRASH AND POTENTIALLY A FATALITY. I CHECKED THE TIGHTNESS ON THE CONNECTIONS BY HAND, WHICH WERE BOTH VERY TIGHT, THEN I RESEATED AND TORQUED THE BATTERY TERMINAL CONNECTION. I MEASURED THE RESISTANCE ACROSS THE POWER JUMPER, LUG TO LUG. THIS IS GM PART NUMBER 84494554, AND I MEASURED 0.3 OHMS ACROSS THIS LITTLE SECTION OF WIRE AT MULTIPLE POINTS ON THE LUGS. TRIMMING BACK THE INSULATION AND CONTINUING THE MEASURE, THE HIGHEST RESISTANCE APPEARS TO BE COMING FROM THE WIRE TO THE LUG CONNECTION AT THE FUSE BUS, AND NOT THE CRIMP CONNECTION AT THE BATTERY TERMINAL, AND NOT THE BOLTED CONNECTION TO THE BUS. THERE WERE SOME STRANDS BROKEN AT THIS CONNECTION. I MADE AND ADDED A TEMPORARY JUMPER OF THE SAME WIRE GAGE, AND THE RESISTANCE ACROSS THE SAME MEASURED POINTS DROPPED TO 0.0 OHMS. ABSOLUTELY A MAJOR SAFETY ISSUE IF THE VEHICLE SUDDENLY DIES WITHOUT WARNING. I CAN SEE THIS SAME ISSUE HAPPENING ONCE, I FORGAVE GM ONCE YEARS AGO, BUT WITH THE SAME ISSUE HAPPENING TO TWO DIFFERENT VEHICLES 8 MODEL YEARS APART, THE SAFETY OF MY FAMILY IS TOO IMPORTANT TO BUY GM PRODUCT IN THE FUTURE.

WHILE DRIVING NORMALLY ON THE HIGHWAY THERE APPEARED TO BE A HARD SHIFT BETWEEN FIRST AND SECOND GEAR AND WHEN SECOND GEAR DID KICK IN, THERE WAS A SUDDEN JERK. ALREADY HAVING MADE AN APPOINTMENT WITH THE DEALERSHIP THE NEXT DAY, THAT MORNING A WHIRLING SOUND APPEARED EACH TIME THE ACCELERATION PEDAL WAS PRESSED. WHEN WE GOT THE VEHICLE TO THE DEALERSHIP, THEY RAN A DIAGNOSTIC AND IT CAME BACK CLEAR. I ALSO PAY FOR ON STAR, AND THEY PROVIDE ME WITH REGULAR DIAGNOSTIC REPORTS, WHICH NEVER INDICATED A PROBLEM AND THE CHECK ENGINE LIGHT NEVER CAME ON. THE VEHICLE APPEARED FINE ON PAPER BUT WITH A TEST RUN, THE DEALERSHIP WAS ABLE TO SEE THE PROBLEM AND TOLD US WE NEEDED A NEW TRANSMISSION. A MECHANIC TOOK OUR OLD TRANSMISSION APART AND SAID THERE WAS A PROBLEM WITH THE TORQUE CONVERTER AND WHEN IT WENT UP IT SENT SHRAPNEL INTO THE PUMPS AND DESTROYED THE TRANSMISSION. THIS SEEMS TO BE A COMMON PROBLEM WITH CERTAIN GM TRUCKS
