Headlights would take turns randomly working, then one night both headlights turned off while I was going around a corner at 55mph. This was in the country no street lights. Just as I came to a blind stop there both kicked back on. After getting home I took apart to find some wires were rotting other already bare, and others cracking. I pray this doesnt happen to anyone else because if this problem isn't fixed someone's going to die. Also if someone does crash I pray to god they can quickly get out of car before all those bare wires behind headlight get smashed together and the fire starts.

Failures of multiple wires/electrical components in the tailgate/rear window wiring harnesses. Search for BMW E61 tailgate wiring problems. The failures are caused by a poor design where the wires entering the hinge guides (4) for the glass and tailgate are repeatedly flexed at a sharp angle until the insulation, then the copper wire breaks. Safety issues - possible electrical short circuit leading to fires (highest load is for rear defroster); lighting failures (rear high brake light, license plate lamps and others); reduced visibility due to loss of wiper/washer/defroster; rear glass latch opening while underway, possibly resulting in loss of cargo or ingress of exhaust fumes. This is not an easily repaired problem and has cost over $2000 so far. I'm worried about driving this car as it is the main transportation for my children and their friends.I discovered it when the remote lock/unlock using the key fobs failed, the trunk inoperable and uncloseable, the radio stopped working, the lights in the rear of the car stayed on permanently and I had to drive home one night with the trunk wide open because the wiring had stopped working and it could not be closed. As I investigated I found many broken ground wires, along with several others with broken insulation, some with broken copper strands etc. I have already had the right and left wire harnesses replaced at an independent dealer for about $2200. This is a safety issue and I'm worried that more will come.
