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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

While driving vehicle, all electrical stopped, discovered that the ignition had turned off by itself and caused a loss of all power creating dangerous steering and stopping situation.. I was able to pull to the side of road and stopped vehicle. Took the truck to Chevrolet dealer in sarasota rt. 41 and bee ridge and was told it was not part of recall. This does not make sense, it has the same symptoms as the other defective vehicles maybe they don't want to increased their problems with another year and model. Please help, I am unable to drive my truck for work and am losing money and customers, as I am a general one man contractor. Please advise.

Wire harness fire. Water got into the end of one of the connectors from the wire harness going into the trasmission. The result of the water getting into the transmission caused an electrical fire and caused a short in the transmission and engine wire harness, the final result was the wire harness was completely burned up. There was evidence of glueing the connectors years ago.I if the connectors are not sealed, it is possible for water to enter and short out connectors and other electrical components.

The consumer stated that while driving at 50-60 mph 2003 Chevrolet Express stalled. The vehicle sat for about a minute, then it restarted. There were no lights that came on the dashboard. This happened with no warning. The dealership has not been contacted as of now. The manufacturer has not been called. The consumer was going to contact the dealer so they could examine the van. The vehicle was taken to the dealer but they found nothing wrong with the vehicle.
