WHILE DRIVING ON THE FREEWAY, THE ELECTRONIC COOLANT THERMOSTAT SHORTED OUT AND CAUSED ENGINE WIRING HARNESS THE BURN UP. THIS CAUSED THE ENIGINE TO STOP RUNNING. LUCKILY, BURNING WAS RESTRICTED TO WIRES AND NO OTHER COMPONENTS WERE BURNT. CAR IS STILL WAITING FOR A NEW WIRING HARNESS AT THE BMW DEALER ($2000 EST FOR REPAIR). I HAVE HEARD OF SIMILAR OCCURANCES WITH THIS MODEL CAR AND WITH 740I OF ABOUT THE SAME YEAR. THIS SEEMS TO BE A DANGEROUS SITUATION AND SHOULD BE PREVENTED BY A FUSE OR FUSABLE LINK.*AK

While stopped (engine still running) at a gas station, the driver side airbag and driver side side curtain airbag both went off. The battery disconnect feature was also triggered. Very lucky I wasn't driving when this occurred.

MY SON WAS DRIVING HOME IN RUSH HOUR TRAFFIC ON CONNECTICUT AVE. IT WAS RAINING RATHER HARD AND VISIBILITY WAS LOW.

MY TRANSMISSION WOULD NOT ACCELERATE OR MOVE. I HAD THE TRANS REBUILD AND 2 YEARS LATER THE SAME PROBLEM. THE TRANS HAS LOST GEARS 1-3 AND REVERSE, MULTISTATE REPAIRED THE TRANS AGAIN 2013, IFOR THE SECOND TIME, IT NEVER WORKED AFTER REPAIRS. THE ENGINE LIGHT STAYS ON, BMW SAYS I NEED NEW TRANS AND ENGINE. WHEN I LOOKED UP RECALLS FOR 540I, IT STATES THE SAME TRANS PROBLEM AND IT SHOULD BE REPLACED. WHEN I LOOK UP ENGINE THERE ARE KNOWN ENGINE PROBLEMS WITH 540I, NOT MY VIN. I ALSO HAVE ELECTRICAL ISSUES, WHICH HAVE A RECALL ON 540I, BUT…
