I brought a 2017 Yukon GMC from a dealership. When I first drove it on a highway it began to pull and shake, to the point it slow down on the highway. Also the dashboard started to shake , vibrate on the highway. When I step on the gas on a local road ,the transmission is pulling to pick up speed. Took it to a Mechanic and explained to him what was going on he test drove it and told me it's the transmission. He also said this year truck " GMC" truck like this has bad transmission. I did my research and find out that it is true. I have a disabled mother that I take to her doctors appointment and I'm scared bto out her in this truck. This is a 1 vehicle and anytime the truck will just slow down or vibrate or shake. No check engine light comes on when it happens.ifni driving on A highway sometimes the check engine light will blink 3 to four times then go back out.

Vehicle Malfunction Incident Report On [11/2724], while stopped at a traffic light, the vehicle experienced a sudden and significant loss of power and gear shifting capabilities. The engine accelerated, but the vehicle struggled to move and shift gears, making it difficult to cross the intersection. After a short distance, the vehicle accelerated again, but there was no forward movement. The vehicle was subsequently parked in a nearby neighborhood, where it became completely immobile. Attempts to engage reverse or drive were unsuccessful. The vehicle emitted a loud noise, and a check of the transmission fluid and other fluids revealed no issues. After turning the engine off and restarting, the vehicle was able to engage drive, but it was limited to second gear. The vehicle then lost momentum again, making it difficult to reach home. It is important to note that no engine light illuminated during the incident, and there were no visible fluid leaks. All routine maintenance has been performed according to the manufacturer's recommendations. A mechanic has inspected the vehicle and diagnosed potential transmission issues.

The engine light has come on spuradically for the last 1.5 years and has been consistently on since May of 2023. This starting approx. 95,000 miles. During this time after starting the Yukon it is chuggy and missing, as I drive off it jerks and darts forward. Seems to be when I stop and start to go this happens, again engine light is always on...sometimes flashing. Starting 9/19/23 (106,000 miles) when slowing down to turn into a parking lot the engine revved high, no movement with the touch of the gas pedal and suddenly takes off with a jerk and a squeal of the tires. VERY SCARY. Since then I have experienced this DAILY, at least once a day. So far it is when I am going slow, either taking off and accelerating or slowing down. The engine and RPMS rev up and go high with no way of moving when touching the gas pedal then suddenly jerks and takes off with the tires squealing. I am also experiencing the transmission shifting VERY hard, mainly when slowing down. I am feeling very timid and scared to drive this vehicle...this is a seriously dangerous situation and can cause a serious accident or life! I believe this fits into the description of the GM Class Action Lawsuit filed over transmission problems. When I previously talked to the dealership they kept saying that there was no recall for the problems and to bring it in. I am not going to continue to get things fixed that do not fix this problem, as I have already. I know of a friend who has the same vehicle/year only a Tahoe and is experiencing the same problem and had work done at a dealership with no fix for their issue neither. Something has to happen with this problem from GM! The contact stated the issue has gotten worse pushing down the gas pedal rendering the vehicle immobile, then all of a sudden it jerks and shifts into gear jolting the vehicle forward.

Check engine light came on and flashing, stabilitrack light comes on, vehicle idles rough and eventually stalled out. This has happened to me twice in my 2017 gmc yukon. Once at ~53k miles, again at ~64k miles. One time it stalled on the side of the road with my kids in the vehicle with me late at night on vacation and had to be towed in the middle of the night and we had to stay in a hotel out of town unexpectedly. The 2nd time happened closer to home but had to pay for a rental car since this is my only vehicle and the dealership no longer does loaners. The vehicle runs rough while driving, loses power, and seems to lose control. It is very scary when it happens. Happened in oct 2019 and again july 2020. It is the same issue as described in n182198000 special coverage memo (dcs5097) from july 26, 2019 but isn't covered in my state yet apparently.

Vehicle has a rough idle at cold start. Also misfires at stoplights and random times. Vehicle stalled once this morning completely. Told by my gmc dealership this is a common problem and I would have to replace all fuel injectors for over $2,000. I just purchased this vehicle in march. The fuel injectors are on back-order currently so I am unable to have it repaired. I was told another vehicle like mine at that service center has been waiting already for 6 weeks for fuel injectors and that I would have to wait at least another month. This means I will not be able to register my vehicle with my state as it will not pass smog inspection with a check engine light. I have been unable to register it due to the dmv closure from covid-19. Its very dangerous to drive a vehicle that can stall at any moment and is impossible to fix without waiting for parts. These parts are obviously on back-order so long because this is a widespread problem. I found a service bulletin from the federal safety agency ( dcs5097 ) which covers my problem exactly. But for some unknown reason, special coverage only applies to 13 states. I believe this is a much more widespread problem than thought and I believe my safety and the safety of those around me is at risk if I drive this vehicle. My vehicle and those like mine should be covered by special coverage as well. And at the very least the parts to fix this should be available given that its been a known issue now for well over a year. These parts have been back-ordered way before covid-19 even hit, so it cannot be attributed to that. Gm has an obligation to keep their vehicles on the road safe and maintained to the best of their ability and when it comes to this issue they are failing to do so.
