Open the full vehicle complaint log (all categories)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.
IMMEDIATELY AFTER FILLING THE TANK WITH GAS, I STARTED THE ENGINE AND IT ACCELERATED TO FULL CAPACITY. THE ENGINE HAD MADE CLICKING SOUNDS, AND OTHER SOUNDS WHEN IT STARTED.
