Constant battery problems with 2019 Ranger Wildtrack

I drive a Ford Ranger Wildtrack with the 213hp machine and have actually always had smaller problems with the battery. 1. In 5 years the start stop has worked exactly 2x, otherwise not 2. On the passenger side the door handle sensor only works when the battery is absolutely full 3. Instead of the usual Ford Sync tones can be heard with all functions only a gruesome beep. 4. The heating works in the winter only the first 20 minutes. After that it gets cold in the vehicle. In addition, it seems that the vehicle falls from a certain outside temperature into a kind of battery protection mode and not necessarily necessary systems simply shut off. I have the circumstance in the past years already repeatedly complained. The dealer found nothing. I had the vehicle in November at the 60,000 inspection and there also the inspection of the battery commissioned. According to the calculation without finding out. HEUTE I get into the car, push on’s button – battery dead. I still managed to start the vehicle, to which I have really switched off every consumer. But how can it be maintained. Anyway, My car has not been able to find any faults in the car.
