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

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.

I have 47,078 miles on this vehicle. It currently has a random misfire that is being blamed on bad fuel injectors. To replace all of my fuel injectors will cost me approximately $1783 at my local dealership as my vehicle is 10,000 miles over warranty. I shouldn't have to be replacing fuel injectors on a 1 year old vehicle. It runs on limited power mode when I start it. I have to start it and then shut it off again for it to run in normal operation but it still shows a misfire code.

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.

May 17, 2018 check engine light came on while driving. Dealership said injector #3 was bad. Replaced same day. Then check engine light came on again while driving on 6/13/18. Dealership said injector #6 is bad. In progress of replacing it. This is a new vehicle with 13,000 miles on it currently. Bought the vehicle new from the dealership Sep 30th, 2017. Two bad injectors in 9 months with the occurrences happening within less than a month of each other? something has to be causing the injectors to go bad.
