If the car is not started within two days, the battery is completely dead. In the past 9-12 months, we bought two new batteries. We've taken it to three mechanics plus the dealer and are told this is a chronic problem with that year Cadillac. Until the last year this was never a problem!! The dealer used the diagnostic machine and found nothing. Car was bought new in '95 and has only 39,000 miles on it. We are at a loss and would appreciate your review and recommendations.
