A couple of years back I had issues where fuses were blowing for no reason. I could also start the car when hazards were on without the key. Ignition off
Solved the situation when auto electricians added quite a few more fuses and unscrambled the circuits where several circuits appeared to use a single fuse.
My car is April 2012.
Seems that it was possible to get feedback across various circuits and separating the circuits with their own fuses stopped this
Had no issues since then. Fingers crossed.
