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.

problem #3

Silverado 3500 4WD 8-cyl

  • Automatic transmission
  • 3,000 miles


Lights for instrument panel occasionally does not work. Battery died. Radio made loud humming noise even when car shut off overnight. Air conditioner broke. But the continual problem is the 4WD becomes inoperable and service 4WD message appears. GM has no repair. They state I must stop turn off the vehicle and restart it in order to "wake up" the electronics. It has been in the repair shop 4 times in last six months when I bought it new. The dangerous part is while driving in ice and snow the vehicle's 4WD became inoperable resulting in loss of control of vehicle and a near miss crash.

Consumer had headlight switch problems. Dealer notified. GM sent the consumer a letter which stated when the headlamp/park lamps were on, the trailer light would not work. The consumer stated if the lights were turned on, the brakes would lock. The trailer had come equipped with auto headlights. The light would come on and activate the trailer brakes. The dealer refused to replace the wiring harness plug unless the consumer purchased the new model plug.
