Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

At approximately 2:30 am, November 10th, my husband had just gotten back from the store, and had turned the truck off. The keys were not in the ignition at the time. He was sitting in the truck for about 10 minutes, when he noticed smoke coming from the dashboard. He opened the hood, noticed flames, and tried to put it out with a fire extinguisher. We called the fire department, but by the time they got to the house, the entire cab of the truck was engulfed in flames. The heat was so intense it melted the siding off my house. The truck was used for his business, and he had two chainsaws in the back that were destroyed. There is absolutely nothing left.

Service brakelines rotted and caused a complete loss of service brakes - while driving and close to home - used emergency brakes and low gear to get to home. Spoke to friend at Chevy dealer. They are having problems with this truck series due to corrosion and premature rusting. Truck is currently in garage due to failure (corrosion) of transmission cooling lines. Current mileage 15,211. Lost both anti-lock brake modules and alternator and temperature sensors.

Was driving my 2006 Chevrolet Silverado 2500hd and turned on the air conditioner. I began to smell an odor similar to trash burning. I turned off the ac and turned on just the air fan at which time the truck cab filled with smoke. I was able to pull off the side of the road and contacted the fire department. The fan continued to fill the cab with smoke even though the ignition was off and the keys were removed. The incident did not stop until the fd disconnected the batteries from the truck. The vehicle was towed to a Chevrolet dealer and the problem was diagnosed as a short in air conditioner blower wiring harness which resulted in damage to the relay, they checked with the manufacturer to authorize repair under an extended warranty and told me it is not covered as it is an electrical malfunction.

Loss of blower fan due to burnt/melted wiring harness & blower motor resister burning hot enough to cause a fire. Loss fan motor to A/C & heat. On line there are thousands of the same complaint. What is GM waiting for people to die before they do something about this.

The contact owns a 2006 Chevrolet Silverado 2500. While driving approximately 40 mph on normal road conditions, the contact heard a loud whistling noise coming from the instrument panel on the passenger side. There were no warning indicators illuminated on the instrument panel. The vehicle was taken to an authorized dealer for inspection, but they were unable to determine the cause of the failure. It was suggested that the failure could possibly have been related to the heater core gasket. On five separate occasions, the vehicle was taken to an authorized dealer for identical failures, but there were no resolutions. The vehicle has not been repaired. The failure mileage was 8,000 and current mileage was 21,700. Updated 04/21/09.
