The contact owns a 2004 cheverolet Silverado 3500. On April 20, 2008, while driving approximately 70 mph up hill, the vehicle downshifted on its own. The engine lost power. The contact pulled over to the side of the road to check the engine. The engine was still running when he opened the hood and he noticed oil and diesel fuel all over the engine. The vehicle was towed to a Chevrolet dealer. The mechanic tested the cylinder by blowing air into it and the air traveled to the crank case. After the mechanic performed this test, he informed the contact that the piston was cracked and a hole was present. The mechanic also stated that the fuel injector failed and caused the cylinder to fill up with an excessive amount of fuel. The failure caused the engine to overheat and blow. The vehicle has not been repaired. The current and failure mileages were 70,800.
About 1 month after buying a new 2004 Silverado it started surging viloently when cold. It is inconsistant, sometimes lasts for blocks. I almost got rear ended last week while tryig to control the truck. GM refuses to do anything, saying there is no diagnosis codes set and they have never heard of Silverado`S surging. They class it as a feature and say I need to feather the clutch. Feathering the clutch in traffic is a good way to get killed. This has been going on about 4 months now. I believe they know what is wrong and it is happening with more then just my one truck; but they don't want to spend the money to fix it.
While pulling inside of the garage the consumer applied the brakes and the pedal went to the floor. The vehicle stopped by hitting the house wall. The braking before the crash caused the ABS and the engine lights to appear on the dashboard which remained on. The consumer was able to drive to the dealer for inspection. The mechanic informed the driver that the problem could not be duplicated.
The vehicle shuts down and lurched forward when it was cold and during inclement weather. This made it difficult for driver to maintain control of the vehicle, increasing the chance of a crash. Took to dealer for checkup, but results showed that the cause was undetermined.
