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.

Car was brought into otto Oldsmobile dealership with 64K for a warranty replacement of a waterpump and for a squealing noise. Was told the intake manifold was leaking and the estimated repair was 600, with the serpentine belt and the waterpump labor total repair was 1100. Car was driven twice after repair, less than 200 miles when squealing returned and engine seized from coolant entering cylinder number four as a result of the manifold leak. Car sat in dealership for three months while we haggled with them and GM for replacement costs. GM denies responsibility and car had an engine installed from a junkyard at a total cost of 350. Car is currently still squealing.
