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.

2800 mileage since new because I have problems fueling the tank. I cannot get fuel to pump into the tank correctly. It's been a problem since I purchased the truck. I've taken it to many different gas stations thinking it was a gas pump issue. The pump handle clicks off when trying to fill the tank. It makes no difference how fast you try to fill the tank or how deep the nozzle is inserted into the tube. I had a Chevrolet service person at the local dealership try to fill the tank to verify my issue. He noticed there is a problem. They checked for a "tsb" and there is one detailing a replacement of the fuel tank. Service advisor stated they would call after getting in the part in 3 days. They never called back. I called back after a week because they never returned my complaint issue. She stated that they cannot get the parts to fix the problem from GM. I do not understand how this is not a recall. I must fill my tank with a gas can to get it to take any gas. A major inconvenience and fuel spillage. I like the truck. I just can't fuel it with a gas pump.

I had two episodes of sudden unintended acceleration while driving highway speeds on a highway. Truck is weeks old- 1500miles only. Brakes still worked so I was able to stop. Rpms continued to escalate in neutral and park. Had to turn off engine quickly to abort the problem. I'm taking the truck in for evaluation tomorrow. My wife and two oldest sons were in the vehicle.
