Noises During Shifting problems of the 2007 GMC Acadia

Transmission slipping jerks and bumps when shifting. Passengers noted there was issues also. Loses power going up hills. Took it to cochran pontiac for two years and did not correct situation, since there were no codes on the computer even though the car had no power and was jerking. Engine light, antilock braking, no rear sensors, and the fuel guage lights are now on after another dealer fixed transmission and I had to pay $1,500 and I should have not paid anything. I did not have these lights on my dash board when I went to get the transmission fixed and the dealer has not fixed them. Recently, my car lost power and died on a blind dangerous curve and shut down the engine. I was afraid to get hit and felt my car was unsafe. We put gas in and would not start and engine was hot. I had to have it towed to dealer after two weeks from getting the transmission repaired and told dealer transmission has noises in it and engine was hot and car would not start. They called and said it was out of gas and runs now, however, they did not address the issues noted above for all of the lights that were on the dash board. The gas was not the issue before car was towed since we put gas in there when it broke down. This 2007 Acadia has had issues since 2011 that continue to present and this SUV is known to have many recalls and is unsafe. The car was taken to the dealer numerous times with complaints by the customer.
