Recently purchased a used tahoe from dealership with warranty.while driving in snow making a right turn the stabilitrac light came on, traction control, and ABS. The vehicle fishtaled, engine lost response. The ABS and stabilitrac warnings continue for a short time and went off. I was able to stop the vehicle safely. Second instance in the rain, on the highway. I was traveling in the fast lane, wanted to move over for a fast moving vehicle behind me. As I was changing lanes the stabilitrac light came on again, this time pulsing the a b s breaks. I had to steer harder to the right, to get out of the way. The throttle response was low as well. The tahoe is consuming huge amounts of gas. About 13miles per gallon. Drags up hill. Seems like it hard to shift into higher gears. Return to dealership for service. Dealer cleaned throttle body, replaced mass air flow sensor. Returned it to me, I told the dealer to drive it,before I accepted it back. Three codes popped up. Back to chevy for diagnosis. Yaw sensor not communicating, etc. I told the dealer I feel the vehicle isn't safe. I gave them a list of codes off my code reader. It doesn't seem they are taking it into consideration. We haven't had the vehicle a month. The dealer is providing a rental. Seems like a common issue with the tahoe and other chevy vehicles. The dealer also told me I had to recreate the problem and/or have the check engine light on for warrenty. The stabilitrac lights comes on intermittently as well as check engine light. I don't think that's fair. They are however trying to figure out the issues. I feel like they sold me a car with known issues.

Stabilitrak and ABS light comes on while driving, the door locks go crazy, radio goes in and out and you lose the ability to accelerate. Engine acts like it wants to die out. The first time I had it taken in, they said it was a sensor so I paid $600 to have it fixed. 6 months later it started doing the same thing so the same sensor was replaced again. One month later my tahoe is doing the exact same thing and now the dealership says it's a short. I don't think they know what's going on and they are just trying different things to see if it works, so now I am out of pocket over $1000 for them to keep guessing what going on.

While driving approximately after 30 minutes, the vehicle would have power issues causing erratic behavior. Example, while traveling on interstate at about 70mph the issues would happen when pressing the brakes or turning on a blinker, the vehicle's door looks cycled several times, it would create a startling pop immediately through the speakers, the radio cut off and restarted. While attempting to pull off interstate, the engine then started to stutter loosing power. Stabilitrack and ABS lights came on. After safely pulled over, cut vehicle off. Restarted vehicle, no issues or power problems. Problem would then randomly happen. Random no power issues - like battery was disconnected. Tested batter - it was ok. Problem became sporadic and random. Dtc showed random issues with electronic brake control module (c0710 -steering position sensor), park assist module (u0073, b1325 - device power 1 circuit malfunction) and passenger presence system (b1000- ecu malfunction) identified grounds to be very bad condition at battery negative to engine and frame, and driver side under body ground at the frame.
