The engine light came on after an 3 days after oil change and begin to cut off when I would accelerate. I took it to carmax and they said it was a faulty sensor which was covered by the powertrain warranty. Carmax suggested I take the car to a GMC dealer for repair. I took the car to the GMC dealer, they repaired it and 1 1/2 weeks later the engine light came on and the car was cutting off again. I went to the GMC dealer a second time and they said, "they could not duplicate my concerns, there was no problem with the car, the engine light is not on and the car was driven for 10 minutes without any issues". After driving the car for 5 days, the engine light is on again and the car is stalling. I have to accelerate over 10 - 20 miles for the car to stay on. I know that something is wrong, I have been afraid to drive because with the car cuts off on me and no one has given a reason as to why. I do not want to get hit from behind. I drive the highway with a small child daily. I am concern that this issue is not being taken seriously. Something is wrong with the car!!!.
While driving in stop and go traffic my car stalled, after restarting it it continued to turn off after acceleration and shuddered when miles to 20 miles an hour.
