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.

Upon purchasing the vehicle I noticed prior to purchase that the fuel gauge did not read accuratly. The dealership agreed to reimburse me for the cost of the fix. After a day or two durring a short in town drive I noticed my speedometer was acting "jerky". I arrived at my destination, but when I left the speedometer was reading 60mph at a stop. At what I estimated to be 65mph the speedometer read 120mph. GM has been aware of this wide spread problem for almost a year but they refuse to issue a recall on a obviously flawed product.

The speedometer on my 2003 GMC Sierra sle is faulty. It began at approximately 37,000 miles and reads between 20-60 mph higher than my actual speed. The problem was initially isolated to the speedometer, but now my tachometer is now reading 800-2000 RPM higher than actual and the amp meter has also started to reading high. I contacted a local GMC dealership and got an estimate of around $600 dollars to fix the problem. The technician I spoke to at the GMC dealership informed me that there have been many similar complaints from GMC owners but no recall has been initiated. I did some research online and found discussion forums where many other GMC owners are experiencing the same problems. I believe this to be a safety issue that needs to be addressed and GMC confronted with a solution.
