Has anyone come across this? After bringing it in for an oil change and alignment, My BMW (X6), had an unusual battery alert. That has gone away, but certain electrical aspects are fading. I now have to put the fob in the ignition to start the car. The radio/cd/Bluetooth doesn’t link/work.When I back up it indicates “ no tones”. It seems to run fine, but I’m wondering if it is utilizing the power in the battery and the alternator is faulty and not providing the recharge when I drive? My guess is some of the electrical features, see above, are not functioning due to lack of power. Or perhaps the battery is shot? Any insight would be greatly appreciated.
