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.
