What owners wrote

Ground wire for passenger side tail light burned up. Ground wire, both sides of electrical connector, and tail light bulb holder all burned up. Passenger side brake light, tail light, turn signal and back up light do not function at all. Improperly rated fuse did not blow before circuit burned up and melted. This circuit is not designed correctly. This is a safety hazard to myself and anyone driving behind me. Car model is a 2008 528xi.

Reported at 72,500 miles, April 2011 Fire

Vehicle is 2008 BMW 535xi wagon. Blocked sunroof drains meant that water drained into the vehicle, gathering in the trunk where the electronics sit. Car had multiple engine failures and warnings of transmission failure, electrical failure, sunroof error and tpm failure. Cause per BMW was blockage of rear sunroof drain. This is a common fault caused by poor design of the sunroof drains (too narrow and prone to blocking).
