First time at 30,000 miles, symptoms appeared to be defective starter or started solenoid- found that the battery was leaking at the positive terminal and corroded/ruined cable connecting to battery. Dealer in North Carolina [parks Chevrolet, charlotte replace battery and cables, free]. second time, at 50,000 miles, I checked battery and found leaking again - soaked cable connections in baking soda water solution and re-installed with new bolt. Since that time, I have cleaned the cable connection at battery positive post with soda/water solution at approximnately 10,000 mile intervals. From talking to other owners, it appears that the batteries are the problem - leaking at the positive bolt/terminal connection. As a former mechanic and factory service rep, I have been able to avoid a serious threat to safety by frequent inspection and maintenance, but this is really a dangerous situation and may have frightening results unless some action is taken to correct
