2005 BMW 6 SERIES User Comment / Complaint

My bmw 745i has been in the shop repeatedly to fix a problem with the gas reading mechanism. the car tells me there is gas when there is none or vice versa. twice the car has completely stopped working having to be towed. the most recent time was this morning while driving on the highway the car just stopped. the gas gauge indicated i had a half a tank of gasoline whereas it turned out it was completely empty. i was under an overpass, alone with cars zipping by on my left, a wall to my right and no one to stop me from being struck from the rear! on five separate occasions the faulty part was allegedly changed. first to the right side and then to the left (whatever that means) it still does not accurately read the gasoline.
