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.

I slowed down to turn into another side road and was going 25 miles hour and a Reduced engine speed light came on I could not get over 35 miles hour. got home and called had it towed to shop. They put it on a diagnostic machine and could not find the problem. They drove it for 3 days and put on machine again nothing showed wrong. The light never came on again. I just want to know what caused it to happen, I am scared it will do it again. I looked in car's book and it did not show a warning light like that in it. Please I need some answers so I can get it fixed to make sure it won't happen again.
