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.

The check engine light comes on, then the reduce engine comes. I have taken my Trail Blazer to the Chevrolet dealership, The gas pedel senor replaced ($395.00) I have had the camshaft sensor replaced ($700.00) Per the dealership it could be over 48 things to make the engine reduce power light come. I can not afford to pay for each item to be replaced. They can assure me that the next thing they want to replace clutch fan ($700.00) will fix the problem. If you can not got the dealership to have your car fix where can you go. I can do the hit or miss problem solving. I actual had more confinence in them than they had in the Trail Blazer.
