Unfair Treatment By BMW, to date

I drive a BMW X3 20D, 2022 model. I am at 77,000km and the vehicle's App has consistently given me one failure/ warning message which requires fixing. The message is Failure risk of the starter battery. This message started appearing 2 months ago and I have taken the vehicle to the dealership thrice now. A first they recharged the battery and said message will disappear on its own. It didnt. I travel a lot so I took it back, again they purported to have resolved the issue. The message remained. Third time, the message still remained. I asked why they are not replacing the battery as indicated by their App, answer I get is wishy-washy. My question is, why cant they replace the battery as needed by the car/ App?? Why are they fighting and defying their own App?? Are they waiting for me to have a breakdown on the road (as the App enumerates so many risks pending due to this, and I am already experiencing some!). Are they waiting for the car to be out of motorplan and then ask me to replace battery? for I am now beginning to think this is it. Right now the message is on App, warning me. God knows what else I am damaging on the car by leaving it with this condition, which they know know would need replacement soon after motorplan! This is so so unfair.
