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.

Push botton start doesnt a lot of the time several times a wekk start the engine. Also, the suspension is terribly rough. You can feel every bump!

When pressing the accelerate pedal there seems to be a delay in response. The delay can be as short as a few milliseconds to almost 3 entire seconds. This problem happens randomly, and makes my wife and I very nervous when trying to maneuver or proceed into traffic after being stopped.
