I have a 2012 Hyundai Azera. Every year I have to replace the battery because the battery will run down and the car will not start. ( I buy a brand new battery) When I try to start it, the dashboard lights flash on and off and car makes a click sound. I have had 3 mechanics at the dealership look at it and they can never find anything wrong with it. They hook it up to-do a diagnostic test and find nothing. They replace the battery and it starts right up. It happens every year at the same time every year. ( In Sept) Just wondered if anyone else has had this problem with their Azera....
