2017 GMC YUKON XL Complaints

I am filing a complaint regarding a serious safety issue with my 2017 GMC Yukon XL related to the brake vacuum pump. According to recall information (NHTSA Recall ID: N192268490), certain 2015-2017 GMC Yukon and Yukon XL vehicles are equipped with a defective vacuum pump that may decrease in output over time. This defect reduces power brake assist, resulting in increased braking effort, a hard brake pedal, and extended stopping distances. These conditions significantly increase the risk of a crash. I have experienced symptoms consistent with this issue, including vibrating brake pedal with no slippage, a hard pedal, ticking noises from the engine, a 'Service Brake Assist' warning message, and difficulty braking. This issues usually occur under 10 mph. These problems compromise the vehicle’s braking performance and pose a direct threat to the safety of myself, my passengers, and other road users.

I report years ago the seat belts wasn’t work, also all time I report with GMC vibrations and stops power at roads or low power to go in the freeways some times are to , and screen for gos and radio wasn’t work, this was a bad car . I take some videos but the agency try to charge me to check the car. Al of those put my person or others person in a risk because I lost the power in the middle of the road also, 2 of the seats belts are not working 1 of those is for my child, and the screen for gps can make me crazy at roads the system report construction or objects at road and I decrease the velocity in roads and the car was behind me slow or the screen jump from gps to radio or news or whatever some times the touch doesn’t work and I was lost in the roads driving around. The last thing is the vibration went I use the brakes to stop the car is shaking this was my first new car and is bad car and unsafe car

The engine developed a ticking noise which turned out to be bad lifters and bent lifter rods, and a bad valve lifter oil manifold.

Transmission Failed at 100,000 miles stalling vehicle brakes pushing back on me.

The contact owns a 2017 GMC Yukon XL. The contact stated while parked and attempting to start the vehicle, the contact heard an abnormal knocking sound coming from the vehicle. The contact attempted to depress the accelerator pedal however, the vehicle failed to respond as needed. The contact stated that a dealer and an independent mechanic were contacted. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the camshaft was not aligned. The contact was informed that the independent mechanic would be able to align the camshaft; however, if the failure persisted there would be a cost for the repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to N232430470 - Special Coverage (Camshaft Position Actuator Valve Solenoid - Bank 2 (Left Side) Exhaust); however, the VIN was not included in the special coverage program. The approximate failure mileage was 131,000.

I purchased a 2017 yukon xl denali. In the short time that I have had the vehicle the transmission has started to make a loud audible popping noise when coming to a complete stop. I have take the vehicle to the GM dealership multiple times to try and get the problem fixed and according to them it is something with the transmission that they don't know exactly how to fix. So I am stuck with this 8l90 transmission that is a piece of junk and can't even get a rebuilt transmission from companies like Jasper due to the issues of these transmissions.

The contact owns a 2017 GMC Yukon XL. The contact stated that while stopped on several occasions, the accelerator pedal was depressed; and there was a loud clunking noise coming from the engine compartment and the vehicle violently jerked each time. There were no warning lights illuminated. The vehicle was taken to a dealer seven times however, the failure was not replicated. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.

Noting that prior to this we only had one issue with transmission and we did the flush and it did fine for several thousand of miles. Fast forward to a few days ago. As I was driving down the highway I came to a stop at the red light. Once it was green and I pressed on the accelerator with my foot per usual. And it did not move it pushed the gas peddle and nothing at all happened. I was stuck in the highway could not move until I’m assuming the transmission finally shifted jarring my entire car and it allowed me to get to a safe place at 20 miles an hour max. Keep in mind I was in the middle of the highway not knowing what was happening. With my precious babies in the car. Thanking God we were not injured. This problem is so common and notorious among GMC Yukons 2017 year models. It’s saddening that now I have a car note on a car that will not go. Transmissions are back ordered who knows when I can have my car back this economy is horrible trying to stay afloat. And now we have a vehicle that won’t drive and no time forks of when it can drive. This needs to be addressed asap. Other people are dealing with the same things and GMC need to make this safety concern a thing of the past. Make a recall.

Had the torque converter replaced at around 58,000 miles because of shutter in transmission. At around under 100,000 miles I called the dealership back up because the shutter is back again and now my NEW torque converter is bad. They said they only had a 25,000 mile warrantee on the new converter and I was out of my replacement window for warrantee. Everything online says torque converters can last well over 150,000 miles and sometimes even the entire life of a vehicle. I have now had two replaced. By searching online for info about this it is CLEARLY a known problem with these vehicles and gmc isn’t doing anything about it.

I want to relate an incident that thankfully did not result in a serious mishap or injury. It Occurred on Canada’s most busy highway. On Saturday [XXX] We were just coming off [XXX] and traffic started to backup. It was heavy. It is then that I lost all control of the Vehicle’s speed. The transmission gave way and left us unable to accelerate as the traffic began to speed up dramatically. I quickly hit the flashers and coasted to the shoulder avoiding the speeding traffic. I managed to get a bit of forward movement to stay out of the way. The transmission would not work at higher speeds. It was nerve racking and we felt unsafe in our predicament. To avoid towing charges, we slowly and carefully took an exit to get on a less travelled road and shut off the vehicle to let it cool. After restarting it we were able to slowly limp to a GM dealership on Fairview in Burlington Ontario Canada. They could not help us as their Transmission mechanic was off for two weeks. My daughter eventually came and picked us up. I left the vehicle at the GM dealer to pick up later after attending our function in Toronto. Later in the evening we returned and were able to return to our Canadian residence in Niagara Falls Ontario Canada by driving well under the speed limit on the [XXX] highway. We then took the vehicle, again at low speed we took the vehicle to Falls Chevrolet, Cadillac, Buick, GMC where their transmission mechanic was out for training. We left the vehicle with them for a week. They advised me that the transmission was basically unrepairable and too costly to rebuild, so we went with a complete replacement. They were very helpful. It was expensive. This happened at 119,000 miles. The Yukon gave no indication of a failure till it happened. We have driven long distances with this vehicle. I understand this is not uncommon with this make and model. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
