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.

1998 Buick Regal Owner Comments

Complaint received via E-mail. Intake manifold was causing leakage of the antifreeze that eventually leaked out the exhaust pipe. This led to other repairs that needed to be fixed.

Regal 6-cyl

My car's radiator cooling light came on, and I discovered that the overflow tank was empty. Since it was zero degrees out, I was afraid the engine would freeze. My local repair shop found the upper manifold leaking and charged me over $900 to replace it and refill the cooling system. I now discover that this was in two previous mfg bulletins. Buick refuses to reimburse me saying I had to drive it to their dealer (a distance away). I feel this is unfair. It is a defect that I discovered they have rectified in recent models.
