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!

Our vehicle is 2017 and we have to replace the air conditioning condenser. I've read that this a issue with these vehicles and it is very expensive to repair. This problem. There should be a recall in place. We as consumers should not have to pay for the neglect of GMC not properly building this vehicle.

My vehicle began shuddering during acceleration and would violently jerk forward after gas pedal was engaged with decreased power in forward acceleration and increase in rpm. This last a couple of weeks. Now, my vehicle is completely broke down and at a GM certified service center. The Service manager states torque converter completely went out and the transmission is burnt up. The mileage is at $61,000, so GM warranty won-€™t cover it and the company that holds the extended warranty I purchased hasn-€™t been able to be successfully contacted. There is a -€œservice-€ bulletin but no recalls and a class action lawsuit (that I-€™m not a part of) but no recall. My vehicle completely lost power going 50mph on a busy road without warning. This needs to be a recall due to this dangerous circumstance.

The transmission failed while merging and almost caused a collision. After a complete transmission replacement, the fuel injectors failed causing the same issue. GM extended fuel injector warranty due to the number of similar issues, but not in my state.

My car is not shifting right. I took it into GMC, and they said they corrected it. I have taken in two times for this issue already. Today I almost was in a car accident because the car would not shift properly and it shoved me forward like A car hit me from the back. The car is not shifting properly at all. And now it-€™s making a muffling sound and it-€™s like stuck in a gear. I pulled over and I parked and then I reversed and then I went to hit the gas again to try to go slowly and it jolted forward again. This is serious and needs repaie

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 NHTSA ( 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.

The vehicle seems to occasionally stall/sputter when accelerating/proceeding from a stop position at a light or stop sign. Even though on a smooth road surface, the right wheel seems to vibrate. The engine stall is the same instance which occurred in the 2015 vehicle that I traded because it left me stranded. The wheel shaking is not a continuous event. The stalling occurs frequently. An appointment has been scheduled for Monday 8/13 for a dealer inspection of my complaint. Vehicle will be left over and a loaner provided.
