I began to smell gas near my gas tank. Upon further inspection, I noticed there was gas leaking down the side of the tank. I then tilted my truck bed to look at the leak from above the tank and I noticed that the plastic piece connector coming out of the fuel pump housing to the supply line was pumping a stream of gas all over the top of the tank. I went to disconnect the hose and the plastic piece broke instantly fully cracking apart. Thankfully this was in my driveway and not driving as this would have been very dangerous. There was no warning light and this would have sprayed fuel everywhere, especially at speed. There are hot parts all over there and would probably resulted in a fire, and at the very least the truck to shut off while driving. I did not take it to a dealer as the damage was extremely obvious. The truck has never been in a crash and I-??ve never changed out any components involving the fueling system, meaning that it simply broke apart on its own. This appears to be a common problem and yet it is not a recall. I had to spend my own money replacing the fuel pump and housing in the tank, as well as the supply line connector as the plastic on that also failed. I started smelling gas and then a few days later is when I found the issue, but I had been driving the truck, including at highway speeds. The truck has 100,365 miles and I-??m the original owner.

Randomly the brakes get stiff, even while on a hill or stop and go traffic. I noticed the first time after first buying it that while on an exit driveway at a decline, the brakes felt like they slipped or went away. I had to push them hard all the way down and thought I was going to roll into oncoming traffic. The truck soon after was making a noise and felt like it was losing power and revving after the keg was taken out and loss of gas mileage. The dealership confirmed the brakes vacuum pump and the high pressure fuel pump were both bad and the gas was leaking into the oil causing problems and possibly ruining the engine, they stated both would need to be replaced. Check engine light comes on soon after fresh oil changes everytime and codes were shown on computer for running rich. No codes after the initial oil changes due to the warning lights appearing after a good amount of gas has leaked into the oil.

There has been loss of power braking at low speeds. The brake pedal has a vibrating feel as it is pressed. The pedal will go down all the way to the floor with very little braking power. I took my truck in for the recall work for the same issue which had no effect. I had a prior problem with a fuel injector going out with less than 50,000 miles on the truck. This caused loss of power in situations where power is needed such as merging on to a freeway. This is a very dangerous situation where someone could be killed. Chevrolet says the fuel injector is not part on the engine even through the maniford had to be removed to replace it. The part was not replace under under warranty. This part should not be failing under any circumstance.

The engine has a ticking noise like a lifter out of adjustment. I'm told this is normal its a ticking fuel pump for the fuel injectors. I think GM is better than that and can figure out how to quite it down. If there engineers can't figure it GM should consider finding some that can! the next time I buy a GM product it will need to be quite if not I'll brake a family tradition for 80 years and buy another brand.

Fuel leaking from engine. With 9595 miles on the engine the truck leaks fuel from the engine like crazy. Vehicle is 6 months old. Can't get Chevy to pickup the rig because they say I need to call the fire department - the fire department tells me there is nothing they can do - been battling with Chevy all day on this. Its a safety hazard cabin smells like the inside of a gas tank - I don't feel save driving it anywhere.
