2015 GMC Yukon Powertrain & Transmission Problems

The contact owns a 2015 GMC Yukon. The contact stated that while in reverse(R), the vehicle jerked while depressing the accelerator pedal. There was no warning light illuminated. The contact became aware of fluid spots on the driveway while the vehicle was parked. The vehicle was taken to an independent mechanic who discovered a leak in the transmission oil cooler line. The dealer then informed the contact about NHTSA Campaign Number: 14V152000 (Power Train); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure and transferred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

The transmission failed at 59,700 miles. The transmission will shift up and down by itself. The transmission is revving up when trying to pass and the vehicle will go limp for a few seconds and then the gear with kick in really hard. In stop and go traffic the transmission slips constantly and could cause an accident due to the limp mode.

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.

Steering jerks sometimes transmission would not go into gear just raves up and then there’s times when it drive normal transmission bangs shifts hard stutters late shift driver assist blocked

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 vehicle started out with a rumble and driving rough. Then it started jumping out of gear. Took it to Transmission shop and they said the have had a lot of SUV’s of the same model with the same problem. It was the transmission. Had it fixed, with a hefty price of 4,900 dollars.

Consuming a lot of oil, makes a funny clicking noise sometimes when accelerations, had lil pieces of metal in my oil, Transmisson problems, 1 front headlight and all rear tail lights went out, trailer brake system would come on and go off now it won’t stop dinging and makes a whole bunch of other lights come on (trailer brake system, park assist, low brake fluid, traction control, collision) dings some much I can’t drive it. Called a gm shop near me and they told me it would cost a whole bunch for each diagnosis for every warning that came on.

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.

Today my GMC Yukon, lurked forward so hard it hurt my neck, shoulders, and back, I know this is dangerous and has happened before, the lurches are becoming more forceful and powerful and I'm afraid now of driving it far or distance, I don't want anything to happen to me or my family while driving, I must be able to get to appointments etc. This today scares me really bad and I need help with this vehicle...Had I not braked quick I would have been in the pond in front of me the lurk was hard pain shot from back to neck and I went forward, had on my seat belt loges...If not better in the morning I will seek medical attention, I'm really hurting...GMC said noting wrong on both occasions I asked when it was mild in 2019, again 2023, nothing...no...also no warning lights are on

Vehicle had lifter and valve noise Lifters and valves became stuck due to Active Fuel Management system failure Transmission shifted poorly due to this condition. Resulting in engine failure and engine replacement at my expense Total cost $12,000

There was recall for N182180270 Tail Lamps Inoperative, for some reason my vehicle being a 2015 was not included. This issue is ongoing with my 2015 Yukon Denali and is dangerous while operating, it recently started and is intermittent. Also my vehicle has issues with hard shifting and jerking intermittently when taking off.... also a known issue for this year and make/ model of vehicle

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.

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.
