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.

2004 Chevrolet Silverado Owner Comments

problem #1

Dec 012015

Silverado LS 4.8L

  • Automatic transmission
  • 268,890 miles


i now suspect the Ignition Switch Accessory contact is worn out and losing Contact. All Instruments are sometimes dead and Heater/AC Blower sometimes inoperative at the same time.. Since Odometer info is stored in the Instrument Cluster the mileage is no longer true. This problem is definitely both a Safety Hazard and a royal pain in the butt. Due to the fact that 268,8XX Miles are on the vehicle it obviously is not a covered item. However it is a Safety Hazard to not having a Speedometer..

The JUNK Stepper Motors in the Instrument Cluster that were Original Equipment have been a notorious problem in ALL GM Vehicles in almost all vehicles GM produced since their inception. I have bought upwards of 15 GM vehicles and this one has been plagued with gremlins.
