NHTSA Complaint #11445639 — 2012 BMW X5

Ever since the rain starter my aux water pump don't work and brake light too. And it seems like something has been draining my battery because battery discharge comes up. And I think the idle idle pulley issue affects almost most of that year bmw X5 because my serpentine belt only installed 10,000 miles ago and already see threads being worn out. Unless that's how long they last. I had to bring the car back in multiple times to get it adjusted because kept making squealing noise. They blamed it on water pump and didn't change the thermostat. Water even leak into front passenger side where all the fuses were. When I connected the battery charger I could hear the pump all of sudden working and the radiator tank sputter water out. I don't want to bring it to dealership and get charged for things that they should fix with charging me but they tell me it's some other issue and have me pay for it. The way they act are worse than gangsters because if you get it fix elsewhere they say it's not covered by them them. And the driveshaft issue, even alot of the cars not in recall are affected and how are they to assume which car need replacing and which dont? I think the v8 engine is just too much power for the other parts to handle and they don't want to admit it. Because how many bmw X5 owners complain about these issue ??
