Transmission failure. Remanufactured transmission installed at 160,000 miles. Transmission started shifting abruptly and failed completely on interstate 26 in South Carolina. Had to limp home in a lower gear. Towed to a repair shop for complete replacement with a remanufactured GM transmission Total repair $4500. No warning indication of the problem, thankfully my wife was not driving this vehicle at the time. No inspection except by mechanic who stated based on his experience we got 10,000 miles more than normal for a GM 6L80 transmission. He also stated his shop replaced 5 of those transmissions in the month of August 2022. Documentation available on request.

Transmission Code P0700 and P0796 ( pressure control) I was on the Interstate and my 2015 GMC YUKON SLT Engine locked up and shift down to 2nd gear. Causing other cars to almost hit me from behind and possibly causing an accident. I had to quickly veer off on the side of the road so that they wouldn-€™t hit the back of me. Immediately my engine light came on. Didn-€™t have this problem prior to the breakdown. Brought it to GMC dealership they told me my torque converter was bad along with Computer TCM and Valve body. They said I need a new transmission. My SUV have 132k miles. I called around at other transmission shops and they ALL said they are getting 3-4 GMC YUKONS in to fix a week and knew exactly what the problem was with SUV. They couldn-€™t understand why GMC wasn-€™t correcting the problem. Also, last year had to replace the Cam Shaft, Lifters and Catalytic Convertor that-€™s was $6000 now they tell me $5500 for Transmission. That-€™s $12000+ in repair in lease than 1.5 years. Never have I had this much major problem on a vehicle. This is a major safety issue especially on interstate.

Transmission failure at 167,000 miles. Transmission failed during a 100 mile trip initially slipping and eventually would not engage. Vehicle traveled on I 26 and could have resulted in accident on this 80 mph interstate. This vehicle is typically driven by my wife. No warning and GM Onstar provided vehicle diagnostic check in days prior to failure with no issues. Technician advised this was the 3rd vehicle this month in his shop with 6L80e transmission failure and said they normally fail around 150,000 miles. This is a known failure on numerous general motors vehicles across the product line. Repair required replacement of 6l80e transmission with a factory rebuilt transmission. Cost $4,100.

At certain speeds my vehicle vibrates, like a grinding sound at speeds between 50-55. This is a safety risk because I have children and grandchild that frequently ride with me. I have taken my vehicle back to the dealership and they say it is no codes and send it back to me without fixing the problem. My vehicle has not been inspected by anyone except the GM dealership. I got my vehicle Nov. 2018 and this started happening between Dec. 2018 and Jan. 2019. My check engine light did appear and was flashing around this time. In 2019 I had to replace the rear shocks and I believe they are not working properly now.

Purchased a 2015 Yukon denali back in November 2019. Since purchasing the vehicle we have had to replace the battery, transmission, ac compressor and expansion valve (which still isn't working correctly, because it doesn't blow cold air), and the black panels that are in between the windows. Also, both tail lights have decided to quit working.... which concerns me greatly because cars behind me don't know when I am stopped or applying the breaks. Stopped or have my foot on the break.

Car was parked in front of our house and combusted in the middle of the night while we were sleeping. Car was exploding and engulfed in flames...completely destroyed via fire and the worst damage was in the engine compartment. Cause of the fire is unknown although based on research sounds like NHTSA campaign #14V007000 or 14V152000. Fire department extinguished the fire and police were on the scene.

Brakes don't work well when traveling at low rates of speed. Stopping requires brakes to be pressed to the ground and still may not stop. I have almost had several accidents even after having the issue 'repaired' last year. I've had the problem assessed at 3 different mechanics. I have had to throw my car into park to avoid hitting cars in front of me. Brakes fail while driving in places such as traffic jams, drive thru, school pick up, etc. This is a huge safety hazard and fear that my children may be hurt if this issue is not corrected by the manufacturer. Steering becomes nearly impossible when the brake issues occur. This is an ongoing problem for the last 1.5- 2 years. Also, the tail lights continue to go out even after paying hundreds of dollars for replacements.

On repeated occasions (from 2015 to 2019) I have experienced sudden acceleration at low speeds and sudden jerking motions. The transmission and speed controls are unpredictable and dangerous. This is hazardous and may result in a loss of control. I have also experienced numerous issues with the brakes including a stuck caliper at approximately 42,000 miles. I reported these issues and numerous other issues to GMC corporate, tustin Buick GMC only to be told that it was a software issue and things are satisfactory and safe. GMC contends that the vehicle is fine and declines to assist with issues. This is an ongoing issue. The date below is approximate. The mileage is approximate on all entries.

The 8 speed automatic transmission on my GMC Yukon denali has a slippage issue that has persisted in our vehicle for a while unresolved. GM has replaced torque converter, module and now they are claiming through dealer that the issue resides with at fluid. This slippage is bad because car jerks and sometimes hard. This issue needs to be addressed by GM as they know they have issues with this 8 speed at. The issue happens at stops and at slow speeds.

Vehicle drive train operates erratically in various operating situations and has extensive vibrations between 25-40mph; vibrations are worse in certain gears. Significant lungeing and jerking on shifting gears on acceleration particularly when not accelerating intensely. Most concerning: When decelerating after running at highway speeds and downshifting (I.e. exit ramps, highway service/rest areas), vehicle accelerates (after downshifting) and requires extensive brake pressure to slow and control. Taken in for service 3X at 3 different GMC dealers. Transmission has been reprogrammed 2X. 3rd dealer provided GMC technical service bulletin "#99-04-20-002I: Information on drive train clunk noise - (Nov 18, 2014)" and told it's 'normal operation' and is due to drivetrain 'lash' (aka gear slop or play). Paid $150 to be told "customer concern not duplicated at this time". simply find this hard to believe as the operations as described are readily apparent. In all seriousness: (1) the sudden jerking/slamming of gears on acceleration has been notice by several passengers not just myself, (2) the acceleration on downshifting is a huge liability as the increased possibility of rear end collision is significant and (3) no way is it 'normal' operation.

Transmission has been clunky and jerky from from purchase. The vehicle vibrates between 30 - 35 miles per hour when shifting. The vehicle lurches forward when accelerating as if it has difficulty down-shifting. The problem is present from simply backing up out of the driveway, modest speeds on city streets, or on the highway. When brought back to the dealer, they claimed it was a software issue and "refreshed" the software. The problem has not gone away and did not improve by this software correction. My internet research indicates that this is a common problem with the new 8-speed transmission for the 2015 Yukon denali and Cadillac escalade.
