2017 GMC Yukon Xl

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)

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.

The transmission begin to cause the vehicle to shudder and shake. This caused shifting problems that cause the vehicle to be unable to safely drive down the road. We have confirmed with a mechanic that has seen and fixed this same issue multiple times. Causing the transmission to need to be replaced. This is due to the issues that many vehicles like this one that continues to be a problem. This issues has caused my vehicle to be unable to accelerate and has caused it to stop in the road. This is very unsafe and needs to be fixed for all those with this similar vehicle so no one is severely injured.

The contact owns a 2017 GMC Yukon XL. The contact stated that while at a stop, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated. The contact stated that the vehicle was jerking while driving forward at a slow speed. The contact was able to drive the vehicle to the dealer where the vehicle remained. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 110,000.

Transmission failed with no symptons. No indications of potential issues prior. All recommended service checks done with vehicle, oil changes etc... 75,026 miles. Pulled up to a red light in heavy traffic and transmission would not engage. No forward, reverse, or in Low 1. Tried 4 wheel and 2 wheel drive. Nothing. Yukon 2017 XL SLT model.

We were on the freeway with my 4 small children. The freeway speed is 75 mph. The car had been jerking and hard shifting for over a week and I had it scheduled with a mechanic. As we were driving on the freeway, it lost total power as cars were going to the left and right around us. I was barely able to get it to the side of the road without being hit. This could have been tragic! I took it to the mechanic and the transmission is shaving a lot of metal (that was in the bottom of the pan). I have had to pay to have a whole new transmission redone. This is absurd with a car that is only 4 years old.

Driving on city streets at approximately 45-50 MPH the transmission began shifting erratically and made significant squealing noises. After stopping, the transmission could not be shifted to another gear and was stuck in drive (D) for approximately 30 minutes. After evaluation from a professional auto mechanic, these transmissions were equipped with the incorrect fluid type from the factory that has since been taken off the market. The transmission needed to be replaced at ~99,000 miles.
