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.

My stability track light will come on and my tahoe will decrease in speed when this happens. This has happened multiple times in the past couple of months. My dashboard has a huge crack over the instrument cluster. It made a loud pop sound when it split. There is a rubbing noise coming from my steering column when I have to turn a corner.

2 issues--- 1st--dashboard has cracks in it, which 1 crack is on the passenger side. It could be a safety hazard and cause the airbag to explode causing great harm to a person. These cracks are in the same position as many other consumers who have made complaints. 2nd--engine shuts down while driving; no steering or brake control. Radio shuts off & on, all dash components flicker on and off, gauges turn off, door locks engage & disengage. This happens for 3-10 seconds and then will "reset" and function normal. I've looked at different forums to try to find out what could be causing this and many other people are experiencing this issue.

Stability control warning light began flashing. Instrument panel including all gauges stopped working. Stopped the vehicle, waited and restarted it. Instrument panel and gauges began working. From then on instrument panel and all gauges worked only intermittently. After a few weeks gauges stopped working completely. I was unable to determine, speed, amount of fuel, could not tell if the turn signals were working, back up warning sound was not working, cruise control did not work. Dealer said the entire gauge panel required replacement. The vehicle has just under 50,000 miles.

Was driving vehicle and came to a stop light. While at light felt engine shut down and showed "service stabilitrak and service traction control." turned off ignition and started vehicle again but with trouble. Both lights stay on and vehicle was operable with reduced engine speed. This issue has occurred on several occasions and luckily it hasn't been while driving with my family and causing an accident or death.

I started to encounter the following errors on my 2011 chevy tahoe; service traction control, service stabilitrak, engine power reduced during the winter months of 2012-2013. I could be simply doing the task of warming the vehicle up in the morning, driving on a paved road going 35mph, or full blown in the middle of freeway/highway traffic. The vehicle will violently start to idle with the warning indicators mentioned above, I then have to somehow pull over in the middle of traffic because I'm unable to get any power due to the engine power reduction. Shut the vehicle completely off and patiently wait until it decides to reset. This could happen once a day to multiple times a day. It could happen immediately one after another or at any given time. The service engine indicator will stay on for about a day before it goes away. Leaving you with the impression the vehicle is fine. Well it's not until it happens again and again. I was about to take my vehicle in right before it was turning spring weather was warming, (not sure if this had anything to do with the issue) but surprisingly it stopped. All spring and summer I had not one issue until now! January 8th 2014 and the weather is cold. This seems after reading on a few blogs on the web, numerous gm owners are having the same issue. They take the vehicle in to have serviced and the service fails. It sounds more like a faulty product which is unsafe having the engine power reduced with no ability to get out of traffic in the middle of the freeway.

I was driving on the highway at approx 60 MPH. The truck dropped speed rapidly and without warning. Lights starting flashing and stating reduced engine power - service stabilitrak. When attempting to pull over I applied the brakes and the truck lunged forward. This happened three times before the engine sputtered and shut off - on the highway. Gm/chevrolet states this is not under warranty. The truck is less than 3 years old.
