The contact owns a 2005 MINICooper S. the contact stated the vehicle would not start. She contacted roadside assistance which jump-started the vehicle. The vehicle resumed normal operation. The failure recurred the next day and she was able to have the vehicle jump-started a second time. The dealer removed the battery and there was excessive water surrounding the battery box. The vehicle resumed normal operation for a while until the failure recurred. The vehicle was towed to the dealer where the contact was informed that the battery was entirely encased in water and exhibited corrosion. In addition, the dealer advised that the BST cables and fuse assembly would need to be replaced. The dealer was unable to provide an explanation for the excessive water in the battery.
