We have experienced same
We have experienced same front headlight problems multiple times. The last change of both front lamps cost us almost $200. Despite changing to lower strength lamps with longer life spans we have still had to replace them frequently on our 2011 Outback. We have 80,000 miles and have had to change headlights at least 4 times compared to once on Mazda with 110,000 miles. This ought to be a class action federal lawsuit against Subaru!
