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.

Consumer was blind, and his wife drove him around. But she was having trouble seeing because there was a foul smell that came into the vehicle, and the substance burnt her eyes. Consumer took the vehicle to the dealer/mechanic 3 times, but the problem was not resolved. Mechanic told consumer that he was waiting for a part before he could repair the problem.

Car has a very strong sulfur odor. Catalytic converter has been replaced but did not fix the problem. Car has been into service 3 times. Odor strong enough that passengers have become ill, especially when the sunroof is open. Children at school back away from car due to odor. GM/Cadillac states it is a problem we "have to live with".
