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 stalled while driving at 21000 miles. When the vehicle stalled, the dash read "reduced engine power." The vehicle would not re-start, steering and the braking was limited. The vehicle finally restarted but there was no power, the vehicle idled roughly and would not travel above 3-5 miles per hour. The vehicle was diagnosed with a throttle actuator code. The throttle actuator was replaced.

Silverado 4WD 8-cyl

  • Automatic transmission
  • 46,000 miles


Light ticking noise from engine from about 30,000 miles by 45,000 miles the noise is much more noticeable like lifters tapping. Failure was with one of the cam shaft lobes chipping off a substantial piece of metal ( brake failure as opposed to being wiped ). the repair has not yet been completed but will require new cam shaft, lifters, head bolts, gasket kit.

2004 Chevrolet Silverado. The consumer stated the vehicle stalled while driving on the road. There were no warning lights that come on before this happened. This has happened every time under 50 mph. Was able to be pull over the vehicle and restarted it immediately. The dealership could not duplicate the problem. When the vehicle was restarted it voided the chips memory. This has happened six times. The consumer had the vehicle towed to dealer, and the dealership could not find the cause of the problem. The consumer sent Chevrolet a registered letter with the information, the claim was denied. The problem started on June 29, 2005, and the last time this happened was August 19, 2005. Every time this happened the consumer called the dealership. The dealer determined there was a lower cell N the battery and replaced it but the staling problem recurred. The consumer would like for the manufacturer to buy back the vehicle.
