After the car is shut off, the coolant pump will stop with the car but after a min the car will stay off but the coolant pump will kick on. Runs until battery is drained. I do understand there is a feature to circulate the coolant so help mitigate burn/hot spots but this continues until the battery is disconnected by ECU. Then it won't start because the battery is too low. Ongoing issue for the past 2 years now, happens intermittently. Frequency is random but happens more when it's cold out. But average happens a few times a week when cold out, sometimes it runs well for a few weeks then starts happening again. We had tried to troubleshoot by BMW but no luck. They have replaced battery, alternator, have tried to diagnose about 4 times now but they haven't fixed it since they can't replicate at the BMW Shop. I can hear the coolant pump running as well as feel the water moving. Also tested by Fluke Meter, it drains at about 40 amps (at 12 volts) when this happens, with the car off. Doing anything (opening doors, trunks, locking, unlocking, stops it for a minute but then pump starts again). No errors pop up for it except when the battery is low and then error battery had high discharge pops up.

EVERY TIME I GO FROM I93 MASS TO I90 HWY ON THE EXIT MY CAR SHUTS OFF FOR 3SEC AND RESTARTS THE ELECTRONICS. NOT SURE WHAT DEFECT OR SENSORS ARE IN THE AREA THAT CAUSES THIS MALFUNCTION. BUT THIS ONLY HAPPENS WHEN I TAKE THE SAME EXACT EXIT EVERY SINGLE TIME.

DRIVING ON 4 LANE ROAD AT 40MPH WHEN 2104 BMW 335I XDRIVE VEHICLE EXPERIENCED TOTAL FAILURE-STARTING WITH THE NAVIGATION SCREEN THEN THE ENTIRE DASHBOARD WENT BLACK AND ENGINE SHUTDOWN (ALL IN FEW SECONDS). THERE WAS NO SHOULDER (CONCRETE CURB) SO VEHICLE CAME TO STOP IN THE RIGHT LANE. HEADLIGHTS WERE "STUCK" ON BUT NOTHING ELSE WORKED INCLUDING THE EMERGENCY FLASHERS! CONTACTED BMW ASSIST BUT THEY WERE UNABLE TO HELP BUT SENT OUT POLICE AND TOW TRUCK. CAR WOULD NOT SHIFT INTO NEUTRAL AND WAS DRAGGED ONTO A FLATBED DAMAGING THE VEHICLE. THIS WAS EXTREMELY FRIGHTENING! WE COULD HAVE BEEN INJURED OR KILLED AS CARS WERE BEARING DOWN ON US THEN SWERVING AS WE COULD NOT WARN THEM WITHOUT EMERGENCY FLASHERS. BEFORE SOMEONE IS INJURED/KILLED, THIS ISSUE NEEDS TO BE ADDRESSED STARTING WITH WHY DOES THIS VEHICLE NOT "FAIL-SAFE"?--I.E., WHERE THE EMERGENCY FLASHERS WORK AND TRANSMISSION CAN BE SHIFTED INTO NEUTRAL? THANK YOU!! *TR
