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.

We've replaced the throttle body twice and the gas pedal (due to the sensor behind it) and light still comes on and basically vehicle stops. This is a SAFETY issue - you get no warning - just as soon as the light comes on the vehicle loses power - not just reduced power - but loses all power. I know other drivers are having this issue because I can see the complaints online. Everyone appears to have tried and changed the same parts I have and still have issues. I'm not able to trust it because of this - it's been really good vehicle for me - was hoping to keep it another three years.
