One problem related to battery dead has been reported for the 2008 BMW 528. The most recently reported issues are listed below.
"takata recall" my expansion tank cracked, then it blew up. Something is wrong with my cooling system. My fan would make a loud noise every time I started the vehicle. My thermostat hose deteriorated and my check engine light has been on for about 5 months. In addition my electrical/battery is bad and my car is no longer functioning since 2 months ago. Please help!.
