Horn Assembly Problems of BMW 3 Series

My husband was refueling our 2013 BMW 335i and I was in the passenger seat. During that process, a pickup truck backed up and was close to hitting our car. From the passenger seat, I tried to warn the other driver with our car's horn, but it did not work, so I resorted to screaming as loud as possible since the windows were also closed. Fortunately, my husband heard me and realized what was happening and got the truck¿s attention and prevented a potentially catastrophic collision right next to a gas pump. It never even crossed our minds at the time that a horn did not operate when the car's electrical system was switched off with the ignition key, which one must do for fire safety reasons when refueling. Nevertheless, after we got home we tried the Bmw¿s horn when the car was off and there was no response. We tried our 2005 Subaru outback's horn with its ignition switched off, and its horn worked just fine. I searched on '2013 BMW horn does not work'¿� on the internet and the system returned 18,200 results. While I did not read all of them, I found numerous postings about BMW horns not working when the car is off, as far back as 2006. Some internet postings advised having the key in the ignition. I placed the key in the ignition and the dashboard display and idrive screen activated, but the horn did not. Next, I pushed the start button, without engaging the engine, and only then did the horn work. I contacted BMW assist for technical assistance and spoke to a BMW customer service representative in columbus, OH. He confirmed that the horn is operating as designed. He said he would enter my concern into the customer feedback database. We think being unable to warn distracted drivers about to crash into your occupied but parked car is a hazard at least worthy of prominent warnings to drivers of Bmws and any other vehicle with this "feature".
