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.

2001 GMC Sierra 1500 Owner Comments

problem #1

May 272006

(reported on)

Sierra 1500 LE

  • 42,000 miles


when my battery died, I removed it and replaced it myself. When I turned on the ignition, the radio had a message "LOC". As it turns out, GMC has a secret four number code which they install at the factory to deter theft of the radio. Anytime electrical power is interrupted for more than a minute or so, the radio goes into the "LOC" mode, and will do nothing. My gripe is, that I had to take it to the GMC dealer and pay them $50.00 to find the code (supposedly on the rear of the radio) and program that number back into the radio. Nothing changed within my radio. All of my preprogramed stations were there. What a scam. The owners manual never states anything about the time factor when changing the Battery, and I was never asked if I wanted the :LOC" activated when I bought the vehicle. Sooner or later, every battery dies, and the vehicle owner will be faced with this same $50.00 GMC scam.
