Car died, got a jump from aaa, after numerous tries car started, car was not acting right, driving out of the parking lot car died, called to have aaa come back, while waiting fumes were coming out of the back seat where the battery is located, mechanic arrived and removed the rear seat to find the battery was leaking from the positive terminal the main positive lead had corroded off the battery, and fumes were coming out, he immediately disconnected the battery there was substantial acid inside the car the body structure was damaged from the acid. This was an ac delco battery. I called GM and ac delco this was an original battery. They didn't want to correct the problem. So I went to a Buick dealer and bought a new battery and put it in. I own two Buick 97 and 2000 this is the third time ac delco battery has failed my 97 has substantial damage in the engine compartment from acid that leaked. And I had to replace the main positive terminal end twice because it rotted off. Ac delco needs to address this problem with their batteries they told me that its due to heat and vibration that their batteries fail. That to me is admission and that they know they have a problem and they are not fixing the problem.

Battery is mounted under the rear passenger seat without a protective cover to prevent the leakage of gas. In the event of a broken vent tube or cracked battery case, there is no protection for passengers from explosive gases or leaking acid. The battery should be enclosed in a protective box. There is a current recall on other vehicles for leaking batteries.
