Radio/tape Cd Player problems of the 2011 Volvo XC60

The car has needed 4 battery changes and the last two were in July and October. On one occasion the car died and would not start at all. On October 3, like the multiple times before, the low battery sign came up. When the car was taken in the dealer finally found that there software glitch in their words that was keeping certain modules of the car on despite the car being turned off. We were told a software patch was applied and that would take care of the issue. Today, 11/6/2015, the low battery sign has come on again and the car has automatically decided to switch the radio off to conserve power twice already. This seems to happen every time we are trying to start the car. The first time this happened we were parked and had to get the vehicle towed. The second time the low battery sign came on and we were able to drive the car to the dealer where the battery was replaced. The 3rd time the battery died parked in a parking lot and the car had to be towed to the dealership. The 4th time the low batter sign came on again and I had to drive the car back to the dealership. This is the 5th time the low battery sign has come on and we are about to take the car to the dealership. The sign came on again when we were parked and about to start the car. Additionally, the blind spot assistance system has a camera that keeps malfunctioning. This happens randomly during drives where the camera malfunctions. The only way to get the error to go away is to restart the car.
