2008 BMW 535XI

WHILE DRIVING THE 2008 BMW 535XI, THERE WAS A LOUD SOUND FROM THE ENGINE. A MESSAGE APPEARED "CAR OVERHEATED" AND THE CAR STOPPED IN THE MIDDLE OF THE ROAD. THE WATER PUMP FAILED WITH ABSOLUTELY NO WARNING. THE ACCELERATION WOULD NOT WORK AT ALL AND THE CAR WAS ESSENTIALLY INOPERABLE. IT WAS A VERY DIFFICULT SITUATION WITH VEHICLES APPROACHING ME FROM BEHIND ESPECIALLY WITH NO SHOULDER SPACE AVAILABLE TO PULL THE CAR OVER. I MANAGED TO TURN ONT HE HAZARD LIGHTS AND BARELY MANAGED TO ESCAPE THIS SITUATION WITHOUT AN INCIDENT. THE VEHICLE WAS TOWED TO A DEALER AND I WAS INFORMED THAT THE AUXILIARY WATER PUMP HAD FAILED AND WILL HAVE TO REPLACE IT, THE COST OF WHICH WOULD BE AT LEAST $1,200. WHEN I LOOKED UP ON THE INTERNET REGARDING THIS ISSUE, I HAVE SEEN MANY INDIVIDUALS COMPLAINING ABOUT THE WATER PUMP IN LESS THAN AS LITTLE AS 30,000 MILES. I ALSO STUMBLED ONTO A NHTSA RECALL CAMPAIGN (NO. 11V-521: "ELECTRIC AUXILIARY WATER PUMP") ON CERTAIN 2008 BMW 5-SERIES. I WAS SHOCKED TO KNOW THAT MY VEHICLE WAS NOT INCLUDED IN THIS CAMPAIGN NUMBER. WHAT TYPE OF QUALITY CHECKS ARE THESE PUMPS SUBJECTED TO? I HAVE HEARD OF MANY SUCH INSTANCES WITH THIS YEAR, MAKE AND MODEL. MOST OTHER VEHICLES HAVE WATER PUMPS LASTING OVER 100,000 MILES AND WELL BEYOND. WHY HASN'T BMW ISSUED A RECALL? *TR
