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.

Grand Prix GT 3.8L V6

My speedometer, odometer, and heads up display stopped working one day after the speed jumped up and then back down. I took it into the speedometer shop and they spent 3 days on my car, first they changed out the whole dash thinking that was the problem and they were wrong, so they put mine back in and it turned out that the junction box under the hood was dirty. They still charged 140 to clean this. I guess that is better than charging for their miss diagnosis. I didn't know how fast I was going, except to go off of RPM's and listening to it shift and what I was really worried about was the fact the odometer wasn't reading my miles.
