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.

2002 Pontiac Grand Prix has a faulty catalytic converter because of the plastic parts. The consumer also stated the upper intake manifold had to be rebuilt as well, due to the plastic parts that were used. The catalytic converter became clogged and caused the upper intake to warp.

2002 Pontiac Grand Prix- - catalytic converter failed at 66,300 miles. Put in shop because GM would not stand by their extended emissions component warranty. My cost $690 car is pure junk. Power windows work when it is colder outside, but when temp is above 75-80 degrees can't open windows to breathe>>>>>>>>>>>>>.
