My battery has failed three times in less than three years and has had to be replaced. I have been stranded twice having to wait over an hour to get assistance. Each time I take the car into the dealer they say they can't understand why the battery would fail so soon and then they put in a new one.

A 2003 Chevrolet Impala with 25,500 miles, the battery corroded through at the positive terminal. Acid leaked from the battery down to the bottom of the car. In talking to the manager at sears, where I had the battery replaced, 8 out of 10 ac delco batteries that they replace, fail this way. In talking to Chevrolet service managers, they see this quite often. I was told that ac delco now has batteries made off shore. How long before critical systems are affected?
