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 positive battery terminal post broke loose from the battery, spilling battery acid on the brake tubing. Discussed battery failure with GM and they refused to replace battery due to the fact the vehicle was out of warranty.

Couldn't start vehicle. Attempted to replace oem delco battery with new battery and found acid had leaked from positive side terminal, totally corroding battery bolt, terminal and cables. Acid had leaked onto high pressure A/C line, electrical wiring and brake lines, corroding them. Significant corrosion on body metal. Repair estimates run in excess of $500. Negotiating with GMC for repairs under a products liability claim.

During summer of 1999, I noticed battery acid residue below battery on lines and wires. Cleaned off with oil. Brakes were mushy. In October, 2000 brakes slowed vehicle but required additional pressure to stop. Noticed additional battery acid build up on lines and wiring. Brakes failed Nov. 22, 2000. Added brake fluid. Vehicle would not start on Nov. 28, 2000. Positive battery post separated from battery. Spent two hours removing broken-off battery from battery bolt, cables and installing battery. Poured baking soda water on affected area of lines and wires.

Battery is leaking acid from around the positive terminal down to the brake line at the front passenger's side, in the area of the front tire. Consumer feels it may eat a hole though brake line, and cause the brakes not to work properly. Dealer replaced battery, but only cleaned the other parts affected by the leaking battery acid, even though there are signs of corrosion on these parts.

Due to battery design flaw acid leaks through a screw hole and causes corrosion. This may result in a no-start condition or stalling.
