The contact owns a 2008 Chevrolet Silverado. The contact stated that while driving 10 mph, the accelerator pedal was depressed and became stuck causing the vehicle to crash into five other vehicles. The key was removed from the ignition in order to stop the vehicle. A police report was filed and no injuries were reported. The vehicle was towed to an independent mechanic. The mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 42,000.

The cab to operator communication started slowly diminishing. Eventually all audible beeps, dings and music on the left side of the cab were shutoff. The speed control cruise was not activation, but the button would light up. Currently the left side of the truck, in the cab, is out of power. I am concerned, does this affect the air bag system too? the truck does a self diagnostics monthly and no issues were noted, but they were obvious issues that a diagnostic should have picked up a notable change. The lighting issue I experienced were with each taillight. I would randomly blow tail light bulbs. A closer look showed corrosion and obvious shorting, but no fuse was faulted. Bulb was burned at the connectors. Further review it was noticed that each tail light had water in the bottom. Traveling caused the water to short out and damage the bulb, leaving me with no rear lighting randomly. I have since drilled holes in the bottom of each tail light as there is not way to remove the moisture. I have also inspected the bulb seals and find they are firmly pressing on to the sealing surfaces, which are clean and free from road dust and they are hidden inside the body of the truck. In summary, I would like to receive some level of detail regarding the electrical issue, focusing on how it can be repaired. Regarding the lighting, this is concerning and should be a consideration for risk assessment during design.

Cruise control worked intermittently. Had to replace the brake switch on the brake pedal. This switch does not activate on "light" brake pedal pressure. It is designed to work on firm brake pedal pressure, which can be hazardous when using electric trailer brakes.

Silverado 2500 4WD

  • 20,000 miles
I own a 2008 Chevy Silverado 2500, 4WD, duramax with allison trans. The problem is with the cruise control. Between speeds of 30-45 mph, the cruise will not hold the speed steady going up a modest hill. Rpms fluctuate 500-800 RPM causing the speed to surge upward and then back off only to repeat continuously while going up hill. Had it to dealer twice who said it was normal. Complained to GM hotline at 1-800-222-1020 and was given svc req # 71-806441267. Approximately 10 days later on March 2, 2010, a district rep called me and told me that GM said it was normal and nothing to be done. I complained that this was unsafe, that I never had a vehicle that had a cruise that did this. He was sympathetic but unable to resolve problem. It may not be a widespread problem in that I have a friend living in another state, who has a clone of my vehicle (bought from same dealer) and he states that his truck does not do this. This situation is unsafe and totally unacceptable.

Silverado 2500 8-cyl Diesel

  • miles
Ltr re problems he having with his 2008 chevorlet Silverado 3500 in which he says presents a significant life safety issue; he would like an investigation to be conducted. While driving, the vehicle suddenly began to increase in speed with no action from the consumer. The consumer attempted to apply the brake, but soon the brake pedal went all the way to the floor and smoke started emanating from under the hood. The consumer was able to steer the vehicle into the emergency lane and turned off the ignition. The vehicle was towed to the dealer, however after a diagnoses, no codes were found to determine the rapid acceleration.
