Transmission failure, slipping in overdrive and during takeoff excessive enginge oil usage.
Last may I was driving my car from work going approximately 40 mph a message came on the information screen. Something about going over 160mph. The car suddenly slowed, couldn't seem to find the proper gear. At the same time the speedometer was going up and down showing 60, 30, 80, 0. Then it cut off. I put the rolling car into neutral and started it. It fired up immediately. I put in gear and continued until it was safe to stop. Let engine cool off and drove home. The speedometer continued to fluctuate, it also cut off and flashed the message again. Called dealership next morning and took in. They came back with diagnosis of transmission failure, need to replace. I shelled out $4000 for the transmission, now it is slipping. I drove home today and that message flashed across my screen along with the transmission struggling to find the proper gear. The speedometer was moving up and down. The speedometer was replaced when the transmission was replaced. I have contacted the dealership to schedule an appointment. I also made a formal complaint to gm.
