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.

2005 GMC Sierra Owner Comments

problem #4

Jan 312012


  • Automatic transmission
  • 110,000 miles


Speed odometer was all over the map, probably the reasons for my speeding tickets. Thinking about Dodges for the next vehicle.

problem #3

Apr 152010

Sierra 1500 5.3L

  • Automatic transmission
  • 62,000 miles

Problem only occurs on occasion, not worth labor and repair to fix as I am currently unemployed. My girlfriend has a 2003 Tahoe whose speedometer consistently reads 40mph+ actual speed.

Sierra 2500 6.6L Diesel

I have heard through other web sites the problem was recalled from factory if vehicle had less than 80,000 miles. I bought my truck used with 81,000 miles and 1 month after purchase the speedometer quit working with local mechanics saying it would cost $350- $400 to fix problem, some say as much as $500
