Today I encountered a problem with my vehicle that not only put myself at risk but my children. This problem came out of no where since I have not had any problems with my vehicle before today. When going to leave I turned my car on to have it stall and die. I had someone come out and look at it and got it to work by pushing down on the gas pedals. Said nothing looked wrong since there were no check engine light or any codes coming up on the dash. So I proceeded to leave and go get gas. When going to start my car again it stalled yet again and showed a check engine light. The car then started to smell like smoke and gas to where I immediately turned to car off and had my kids get out. I then tried to start my vehicle again and thankfully was able to get it to work with the check engine light showing. I called the car dealership that I go to for my oil to let them know I’m coming and that it stalled again with the check engine light showing. I made it to the shop and they ran diagnostics on it to show that it was a time change in the engine that was messing up. They then proceeded to let me know that I would have to go to a GMC shop because they can’t do the work at their shop. He then proceeded to tell me not to drive in this because the car will stall in motion and will not go faster than 45 without dying or shutting off. Which to me is a major safety concern since I have to drive it to the shops and let along home with my children in the car. So the whole way I couldn’t go over 45 without my car starting to stall and shake. Thankfully it didn’t shut down with my kids in the car on a main road.

I have taken the vehicle to be repaired 5 times already and GM still refuses to acknowledge the full extent of the issue. My transmission was repaired under 100k miles while under warranty coverage for a slipping 3rd gear, excessive shudder, and hesitation. After a 3 attempts for repair, the 4th involved keeping the vehicle for a number of weeks and replacing internal transmission parts. Within 2 months, the symptoms returned but was out of warranty. The service center refused to diagnose it further without a $1,500 "diagnostics fee". I have brought the vehicle multiple times to the dealership, and have contacted GM seeking assistance on the matter. While the dealership service centers continue to focus on other parts and/or smaller sub-components of the transmission, my vehicle remains UNSAFE to drive outside of my immediate locality. I suffer from stalling, failure to maintain speeds, I cannot pass vehicles, I cannot maintain or obtain highway speeds to keep up with traffic. I have taken it yet again for repair, where the service center refuses to acknowledge the problem. They blamed it on a sensor and sent me on my way, but not only 30 minutes later did the symptoms return full-force. The Check Engine Light has reappeared. Prior to the visit earlier today, it was recently tripped at P0796, Pressure Control Solenoid C stuck or closed. I was on the highway today with avg traffic going 75 MPH. I was unable to merge into traffic and almost got pushed off of the road as a result. The truck also slipped when travelling inclined over the walt whitman bridge in to Philadelphia. It resulted in a bridge closure for 45 minutes while I could get towed off of the bridge. Once i got to the service center, as always, but will not drive over 45 MPH unless its up to 4600 RPM, steadily. This has got to end. Please Help.
