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.

Gauges work some times and don't, lights go off and on the dash when they do this at night it's hard to see what speed your doing our how much fuel you have. This seems to be a problem with a lot of the trucks my neighbors truck is doing the same thing.

When the weather is below freezing the turn signals do not work until the vehicle has warmed up for atleast 20 minutes. Also the speedometer does not work, and when it does start working it is never the correct reading. It will stick as high as 70 mph, and to bring it down I have to keep restarting and shutting off the engine.
