Vehicle intermittently loses all electrical controls: Power steering, engine power, stabilitrak, airbags. All electrical systems are compromised and the vehicle loses all power. Once the vehicle is turned off and back on a few times it will go into a 'limp mode'. I've been stranded in the vehicle 4 times. I have had this happen twice while driving down the freeway, once driving in a parking lot, and twice when first starting the vehicle. During one incident on the freeway I was in the center lane and lost all engine power, airbags, safety controls, and power steering. I was able to coast and make my way over to the shoulder. GM and the dealership have been unable to resolve the issue and are now refusing to honor the warranty, replace the vehicle, or refund the purchase. This has been a serious safety issue. I've had my wife and two small children in the vehicle when it has died on the freeway. Not only is it a significant danger to myself and my family, but any other vehicles in close proximity. As such I have refused to drive the vehicle any longer, but GM seems intent on ignoring this.

Entire instrument cluster went out while driving causing loss of needed information such as speed and other pertinent information. Dealer says there is a tsb that the entire truck has to be re-flashed including all modules in the vehicle because it does not recognize the instrument cluster. During this time, all safety systems flashed and appeared to be inactive. Air bag, traction control, ABS, trailer braking etc. This needs to be investigated to see if a recall must happen. If we got in an accident during this occurrence who knows if any of the safety systems on the vehicle were functioning.
