2017 GMC Yukon Xl

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)

drivers side tail light flickering and sometimes not working a $900+ cost! I issue with right hand side when suv has 32k miles, seems like this is an ongoing issue, luckily it was still under warranty the 1st time. The AC condenser when out in April, also an know issue with the Yukon, they wanted to charge me $1500 to repair, I was able to find someone to do it for around $600, now the outlet and usb ports seem to not work. I also had an issue with the braking system , dealer couldn't figure it out, I finally found someone to repair it, $500 fix. For what I paid for the Yukon, you would think they would use top of the line parts!

There was a pump in the heart of the transmission. The dealer said told me that was leaking fluid. Apparently this was a faulty hose within the transmission which leaked fluid in the transmission. Therefore, my transmission died. This was a severe I could have been a very dangerous situation if my kids had been in the car. I’ve had to pay almost $8000 for the transmission to be fixed and yeah I see that on the line there was some sort of recall but my dealership is saying there was not. I bought this car brand new and I’ve had it for seven years. I’ve never had an issue with the transmission on any of my vehicles ever.

Truck RPMs were running really high between shifting with normal acceleration. I took the truck to a transmission shop as I purchased an extended warranty. The transmission needed to be rebuilt as many parts were worn. The extended warranty repair was made. After repairs, the truck has started doing the same thing 4 weeks later. It appears the transmission is not properly shifting again, I am not sure if it's a transmission issue as all parts have been replaced, or a computer issue that's causing the malfunction. The vehicle is available for inspection. My safety is put as risk because if the transmission does not shift properly, it is at risk at breaking while in motion which could potentially cause an accident and if the transmission breaks will on the highway, i dont know what type of risk that can entail. The transmission shop has indicated that they are noticing the same issue as before and do not see any reason for the issue to be continuing. There were no warning lamps or indicators that have shown up to indicate an issue. This is noticed by daily driving of the vehicle and noticing normal and not normal RPMs, shifting points and feeling.

Car has 100k miles on it. At 59k the fuel injectors went out and needed to be replaced. Then the transmission went out and needed to be replaced, then the front differential needed to be rebuilt, also had to replace the struts. Now the lifters are going out and that, plus likely the camshaft, need to be fixed. Total costs for all the above is close to $20,000. If not fixed these problems could easily result in catastrophic engine failure while driving leading to personal injury and death. I see that there is a class action lawsuit for the latter.
