Starting smelling gas inside of the cab, at first thought it was non-issue, but the smell persisted. Several days passed, and when I went to warm up my truck in the morning smelled a strong gas odor, and when I looked under the engine - there was a pool of gas, and gas was leaking. Took it in to the dealership (thinking it was a simple loose filter line) but they now say that it is more than that. Not sure if this has been a re-occurring issue with these new trucks, but it could have been a very dangerous situation.

Mon oct 8th, 5pm, my chevy silverado 2500hd diesel truck caught fire driving down a city road(approximately 30mph), with me, my 12yo daughter and her friend in it. The engine died, and I lost power steering and brakes. After wrestling the truck to the side fo the road, a passerby drove backwards in traffic to alert me that the truck was burning. If not for him, we might not have gotten out in time. Flaming fuel was dripping down from in the chassis, driver side, in front of rear wheel, approximately where the fueling receptacle was. The pool of burning fuel on the ground could not be extinguished. A passerby emptied a 15lb fire extinguisher onto the area, and was not able to stop the flaming leaking fuel. By now, it was leaking with the intensity of a small shower head. The entire truck burned to the ground rapidly. The truck was two weeks old, with less than 1000 miles. It was unmodified. Gm, chevrolet, and weseloh chevrolet were utterly unconcerned, and unmoved by this disaster. They treated the incident as if I had wrongly complained that the floor mats didn't fit correctly.

While driving on the interstate, we came to a stop at a gas station. When at a complete stop we started smelling diesel fuel, I assessed the vehicle under the hood and under the truck. It was raining that day so I couldn't tell if anything was leaking from the under carriage. While driving the remaining two hours of our trip, off the interstate, we came to a red-light, while making the right turn the truck got sideways in the intersection. Continuing the trip and almost home we were on a highway going 65mph, the truck got sideways and lost traction again. Concerned because I have my wife and 15 month old in the truck, I pull over again to assess the truck. At this point felt of the tires and they had a oily substance on them, causing the truck to not have any traction in the rain, I also seen a substantial amount of fuel leaking from around the transmission. The next day I took it to the dealership to get looked at. They informed me that the high pressure fuel pipes had a severe fuel leak from the connectors. They also informed me that there were no recalls open on the vehicle. So they are wanting to charge me over $1,300 to repair this, when I feel like this is a huge safety issue caused by a lack of quality assurance and control. Also I am fairly certain that this use to be a recall, and the dealership said that there are no open recalls on my vehicle. I feel like there should be a recall on this issue asap, before it kills someone.

Fuel line leak. Two steel fuel lines were rubbing against each other causing a fuel leak. This is a diesel pick up and the fuel system is reported at 28,000 psi operation pressure. This resulted in a leak of diesel fuel that sprayed onto the exhaust system, which can reach temperatures in excess of 1400f causing a fire hazard. The problem manifested as a strong raw fuel smell in the cab causing an inhalation hazard. This was followed by small stains in my parking spot. The smell was not evident when in motion on the highway only when stopped and running. Repairs were made by casper gmc dealer in casper, wy replacing the fuel lines. There is no buffer (such as a teflon bushing) to insulate such effects.
