NHTSA Complaint #10839952 — 2005 BMW X3

I BOUGHT A BMW X3 IN 2005 AND NOTICED THAT WHEN THE MOTOR IS OFF THE HORN DOES NOT SOUND. MY HUSBAND BOUGHT A BMW 3 SERIES IN 2007, AND MY DAUGHTER/SON IN LAW BOUGHT AN X1 TWO MONTHS AGO. AND I HAVE ASKED FRIENDS WHO OWN BMW'S AND THEY SAY THE SAME THING - WHEN THE MOTOR IS OFF, THE HORN DOES NOT SOUND. THIS IS NOT NECESSARILY A SAFETY ISSUE BUT IT CERTAINLY CAN BE. MY BROTHER DRIVES A FORD SUV IN THE CHICAGO AREA. LAST MONTH HIS CAR SLIPPED OFF A VERY ICY ROAD AND WAS COVERED BY SNOW ALMOST IMMEDIATELY! HE WAS REALLY STUCK AND TOLD ME THAT IF HE COULD NOT SOUND THE HORN WHEN A POLICE OFFICER WAS PASSING, HE WOULD HAVE REALLY BEEN IN TROUBLE (CELL PHONE WAS AT HOME - OF COURSE). AND THEN THERE IS MY NOT TOO BIG PROBLEM -- WAITING IN THE CAR FOR HUBBY TO COME OUT AND CAN NOT SOUND THE HORN. LAST WEEK I WAS PARKED IN A LINE WAITING FOR A TRAIN TO COME WHEN THE TRUCK IN FRONT OF ME BEGAN TO BACK UP. MY MOTOR WAS OFF (BEEN WAITING AWHILE) AND I HAD TO FIGURE OUT WHERE I HAD PUT THE KEYS, GET THE MOTOR ENGAGED AND THEN BEEP AT THE TRUCK -- JUST INCHES FROM HIM HITTING ME!
