headlights on subaru b9 tribeca only work on high beam

What is your question?

The headlamps have been replaced 3 x that I am aware of, most recent was two days ago. The running lights work, but the main large headlight only works on high beam. I just purchased the car this week. I do not believe that either recall/repair offer on this vehicle have been taken care of. Please, someone, have mercy!

How long has your 2007 Subaru B9 Tribeca had this problem?

since I bought it this week
