Driving down the expressway at 65MPH, and the Vehicle completely stops, almost causing a collision. After researching the problem at the GMC Dealer, it appears that the entire engine has internally failed. Apparently it was a Complete Engine Failure.

My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue. I kept up on my oil changes and other recommended car maintenance and so did the owner before me. I had my last oil change approx. a week before the loud ticking noise began, then my vehicle began to have a noticeable loss of power when driving and eventually began shuttering and my check engine light began to blink and I took it to the shop. A year ago I had to replace my tail lights. I was able to find where others were recalled by my VIN for some reason was not included in the recall. They started shorting out and working only part of the time which is very dangerous when stopping, especially at night. I had them replaced and paid almost $700 for the two back lights.

My 5 children and I experience a traumatic experience in afternoon traffic as my 2015 GMC Yukon failed to pick up speed while waiting to make a left turn at a traffic light. The vehicle - no matter how hard I pressed on the gas didn't accelerate immediately which almost cost an accident. The vehicle rode smoothly for a few minutes then out of nowhere - it started jerking and stuttering bad for 15 seconds or so then would go back to riding smooth. When pressing the brakes - it seems to "lock" to a certain extent, so I have to press really hard on the brake to slow down/stop the vehicle sometimes makes a strange noise when doing so. I took the vehicle to be accessed by a service center in my area - it was at that time that I was told that my vehicle issues are known common GMC issues in these vehicles & more unfortunately. It's unfair to be penalized with an expensive transmission repair when these issues are known to the manufacture but not the consumer - despite being "VIN specific" as told by GMC customer service. This vehicle is needed as it is utilized to transport my children however, it's unsafe at & parked in my driveway. I was directed to reach out to GMC for remedy of the identified issues.

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.

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.

- Washington, NC, USA

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.
